+
+
+## [4.0.2] - 2025-10-19
+
+### Changed
+- **PM2 bundled as dependency**: Moved pm2 from devDependencies to dependencies for out-of-the-box functionality
+- **Worker scripts use local PM2**: All npm worker scripts now use `npx pm2` to ensure local binary is used
+- **Worker startup uses local PM2**: Worker auto-start now uses `node_modules/.bin/pm2` instead of global pm2
+
+### Fixed
+- **Fail loudly on missing dependencies**: Worker startup now throws explicit errors when bundled pm2 is missing instead of silently falling back
+- **Better error messages**: Clear actionable error messages guide users to run `npm install` when dependencies are missing
+- **Removed silent fallback**: Eliminated silent degradation that masked "works on my machine" installation failures
+
+### Documentation
+- Updated README system requirements to reflect pm2 is bundled with plugin (no global install required)
+
+
+## [4.0.0] - 2025-10-18
+
+### BREAKING CHANGES
+- **Data directory moved to plugin location**: Database and worker files now stored in `${CLAUDE_PLUGIN_ROOT}/data/` instead of `~/.claude-mem/`
+- **Fresh start required**: No automatic migration from v3.x databases. Users must start fresh with v4.0.0
+- **Worker auto-starts**: Worker service now starts automatically on SessionStart hook, no manual PM2 commands needed
+
+### Added
+- **MCP Search Server**: 6 specialized search tools with FTS5 full-text search capabilities
+  - `search_observations` - Full-text search across observation titles, narratives, facts, and concepts
+  - `search_sessions` - Full-text search across session summaries, requests, and learnings
+  - `find_by_concept` - Find observations tagged with specific concepts
+  - `find_by_file` - Find observations and sessions that reference specific file paths
+  - `find_by_type` - Find observations by type (decision, bugfix, feature, refactor, discovery, change)
+  - `advanced_search` - Combined search with filters across observations and sessions
+- **Citation support**: All search results include `claude-mem://` URI citations for referencing specific observations and sessions
+- **Automatic worker startup**: Worker service now starts automatically in SessionStart hook
+- **Plugin data directory**: Full integration with Claude Code plugin system using `CLAUDE_PLUGIN_ROOT`
+
+### Changed
+- **Worker service architecture**: HTTP REST API with PM2 management for long-running background service
+- **Data directory priority**: `CLAUDE_PLUGIN_ROOT/data` > `CLAUDE_MEM_DATA_DIR` > `~/.claude-mem` (fallback for dev)
+- **Port file location**: Worker port file now stored in plugin data directory
+- **Session continuity**: Automatic context injection from last 3 sessions on startup
+- **Package structure**: Reorganized to properly distribute plugin/, dist/, and src/ directories
+
+### Fixed
+- Context hook now uses proper `hookSpecificOutput` JSON format for SessionStart
+- Added missing process.exit(0) calls in all hook entry points
+- Worker service now ensures data directory exists before writing port file
+- Improved error handling and graceful degradation across all components
+
+

+  The GNU Affero General Public License is a free, copyleft license for

+cooperation with the community in the case of network server software.
 
-5. NO WARRANTY: THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
-   EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF
-   MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
 
-6. LIMITATION OF LIABILITY: IN NO EVENT SHALL THE AUTHOR BE LIABLE FOR ANY
-   CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT
-   OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR
-   THE USE OR OTHER DEALINGS IN THE SOFTWARE.
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
 
-For questions about this license, contact: thedotmack@gmail.com
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+## Overview
+
+### What is Claude-Mem?
+
+Claude-Mem is a **Claude Code plugin** that provides persistent memory across sessions. When you work with Claude Code on a project, claude-mem:
+
+1. **Captures** every tool execution (Read, Write, Bash, Edit, etc.)
+2. **Processes** observations through Claude Agent SDK to extract learnings
+3. **Summarizes** what was accomplished, learned, and what's next
+4. **Restores** context automatically when you start new sessions
+
+### Key Features
+
+- **Session Continuity**: Knowledge persists across Claude Code sessions
+- **Automatic Context Injection**: Recent session summaries appear when Claude starts
+- **Auto-Starting Worker**: Worker service starts automatically on first session (v4.0+)
+- **MCP Search Server**: Search and retrieve observations and sessions via 6 specialized tools
+- **Structured Observations**: XML-formatted extraction of learnings
+- **Smart Filtering**: Skips low-value tool observations
+- **Multi-Prompt Sessions**: Tracks multiple prompts within a single session
+- **HTTP API**: Modern REST interface for hook communication
+- **Process Management**: PM2-managed long-running service
+- **Graceful Degradation**: Doesn't block Claude even if worker is down
+
+### System Requirements
+
+- **Node.js**: 18.0.0 or higher
+- **Claude Code**: Latest version with plugin support
+- **PM2**: Process manager (bundled with plugin - no global install required)
+- **SQLite 3**: For persistent storage (bundled)
+

-Your future self will thank you. 🧠✨
+### Core Components
+
+#### 1. Plugin Hooks (5 Lifecycle Hooks)
+
+- **SessionStart Hook** (`context-hook.js`): Queries database for last 3 sessions and injects context
+- **UserPromptSubmit Hook** (`new-hook.js`): Creates/reuses SDK session, sends init signal
+- **PostToolUse Hook** (`save-hook.js`): Sends tool observations to worker service
+- **Stop Hook** (`summary-hook.js`): Triggers final summary generation
+- **SessionEnd Hook** (`cleanup-hook.js`): Marks session as completed/failed
+
+#### 2. Worker Service
+
+Long-running HTTP service (managed by PM2) that:
+
+- Listens on dynamic port 37000-37999
+- Provides REST API for hook communication
+- Maintains active session state in memory
+- Routes observations to Claude Agent SDK
+- Writes processed summaries back to database
+
+**Endpoints:**
+- `POST /sessions/:id/init` - Initialize session
+- `POST /sessions/:id/observations` - Queue tool observations
+- `POST /sessions/:id/summarize` - Generate summary
+- `GET /sessions/:id/status` - Check status
+- `DELETE /sessions/:id` - Clean up session
+- `GET /health` - Health check
+
+#### 3. SDK Memory Processor
+
+Uses Claude Agent SDK (`@anthropic-ai/claude-agent-sdk`) to:
+
+- Build specialized XML-structured prompts
+- Feed observations through iterative cycles
+- Parse Claude's XML responses for structured data
+- Accumulate learnings about modifications, discoveries, decisions
+- Generate final summaries with lessons learned and next steps
+
+#### 4. MCP Search Server
+
+Claude-Mem includes a Model Context Protocol (MCP) server that exposes 6 specialized search tools for querying stored observations and sessions:
+
+**Search Tools:**
+- `search_observations` - Full-text search across observation titles, narratives, facts, and concepts
+- `search_sessions` - Full-text search across session summaries, requests, and learnings
+- `find_by_concept` - Find observations tagged with specific concepts
+- `find_by_file` - Find observations and sessions that reference specific file paths
+- `find_by_type` - Find observations by type (decision, bugfix, feature, refactor, discovery, change)
+- `advanced_search` - Combined search with filters across observations and sessions
+
+All search results are returned in `search_result` format with **citations enabled**, allowing Claude to reference specific observations and sessions from your project history using the `claude-mem://` URI scheme.
+
+**Configuration:** The MCP server is automatically registered via `plugin/.mcp.json` and runs when Claude Code starts.
+
+#### 5. Database Layer
+
+SQLite database (`${CLAUDE_PLUGIN_ROOT}/data/claude-mem.db`) with tables:
+
+- **sdk_sessions**: Active/completed session tracking
+- **observations**: Individual tool executions with FTS5 full-text search
+- **session_summaries**: Processed semantic summaries with FTS5 full-text search
+- **sessions**, **memories**, **overviews**: Legacy tables
+
+**Full-Text Search:** The database includes FTS5 (Full-Text Search) virtual tables for fast searching across observations and summaries, powering the MCP search tools.

+
+## Installation
+
+### Prerequisites
+
+```bash
+# Ensure Node.js 18+ is installed
+node --version  # Should be >= 18.0.0
+```
+
+### Method 1: Claude Code Marketplace (Recommended)
+
+Install directly from Claude Code using the plugin marketplace:
+
+```bash
+# Add the marketplace
+/plugin marketplace add thedotmack/claude-mem
+
+# Install the plugin
+/plugin install claude-mem
+```
+
+The plugin will:
+- Automatically install all dependencies (including PM2)
+- Configure hooks for session lifecycle management
+- Set up the MCP search server
+- Auto-start the worker service on first session
+
+**That's it!** The plugin is ready to use. Start a new Claude Code session and you'll see context from previous sessions automatically loaded.
+
+### Method 2: Clone and Build (For Development)
+
+```bash
+# Clone the repository
+git clone https://github.com/thedotmack/claude-mem.git
+cd claude-mem
+
+# Install dependencies
+npm install
+
+# Build hooks and worker service
+npm run build
+
+# Worker service will auto-start on first Claude Code session
+# Or manually start with:
+npm run worker:start
+
+# Verify worker is running
+npm run worker:status
+```
+
+### Method 3: NPM Package (Coming Soon)
+
+```bash
+# Install from NPM (when published)
+npm install -g claude-mem
+
+# Worker service auto-starts on first hook execution
+```
+
+### Post-Installation
+
+1. **Verify Plugin Installation**
+
+   Check that hooks are configured in Claude Code:
+   ```bash
+   cat plugin/hooks/hooks.json
+   ```
+
+2. **Data Directory Location**
+
+   v4.0.0+ stores data in `${CLAUDE_PLUGIN_ROOT}/data/`:
+   - Database: `${CLAUDE_PLUGIN_ROOT}/data/claude-mem.db`
+   - Worker port file: `${CLAUDE_PLUGIN_ROOT}/data/worker.port`
+   - Logs: `${CLAUDE_PLUGIN_ROOT}/data/logs/`
+
+   For development/testing, you can override:
+   ```bash
+   export CLAUDE_MEM_DATA_DIR=/custom/path
+   ```
+
+3. **Check Worker Logs**
+
+   ```bash
+   npm run worker:logs
+   ```
+
+4. **Test Context Retrieval**
+
+   ```bash
+   npm run test:context
+   ```
+
+---
+
+## Usage
+
+### Automatic Operation
+
+Claude-Mem works automatically once installed. No manual intervention required!
+
+1. **Start Claude Code** - Context from last 3 sessions appears automatically
+2. **Work normally** - Every tool execution is captured
+3. **Stop Claude** - Summary is generated and saved
+4. **Next session** - Previous work appears in context
+
+### MCP Search Tools
+
+Once claude-mem is installed as a plugin, six search tools become available in your Claude Code sessions:
+
+**Example Queries:**
+
+```
+"Use search_observations to find all decisions about the build system"
+→ Searches for observations with type="decision" and content matching "build system"
+
+"Use find_by_file to show me everything related to worker-service.ts"
+→ Returns all observations and sessions that read/modified worker-service.ts
+
+"Use search_sessions to find what we learned about hooks"
+→ Searches session summaries for mentions of "hooks" in learnings
+
+"Use find_by_concept to show observations tagged with 'architecture'"
+→ Returns observations tagged with the concept "architecture"
+```
+
+All results include:
+- **Citations**: Results use `claude-mem://observation/{id}` or `claude-mem://session/{id}` URIs
+- **Metadata**: Type, concepts, files, facts, and dates
+- **Rich Context**: Full observation narratives and session summaries
+- **Filtering**: Project, date ranges, types, concepts, files
+
+### Manual Commands
+
+#### Worker Management
+
+**Note**: v4.0+ auto-starts the worker on first session. Manual commands below are optional.
+
+```bash
+# Start worker service (optional - auto-starts automatically)
+npm run worker:start
+
+# Stop worker service
+npm run worker:stop
+
+# Restart worker service
+npm run worker:restart
+
+# View worker logs
+npm run worker:logs
+
+# Check worker status
+npm run worker:status
+```
+
+#### Testing
+
+```bash
+# Run all tests

+
+```bash
+# Build hooks and worker
+npm run build
+
+# Build only hooks
+npm run build:hooks
+
+# Publish to NPM (maintainers only)
+npm run publish:npm
+```
+
+### Viewing Stored Context
+
+Context is stored in SQLite database. Location varies by version:
+- v4.0+: `${CLAUDE_PLUGIN_ROOT}/data/claude-mem.db` (inside plugin)
+- v3.x: `~/.claude-mem/claude-mem.db` (legacy)
+
+Query the database directly:
+
+```bash
+# v4.0+ uses ~/.claude-mem directory
+sqlite3 ~/.claude-mem/claude-mem.db
+
+# View recent sessions
+SELECT session_id, project, created_at, status FROM sdk_sessions ORDER BY created_at DESC LIMIT 10;
+
+# View session summaries
+SELECT session_id, request, completed, learned FROM session_summaries ORDER BY created_at DESC LIMIT 5;
+
+# View observations for a session
+SELECT tool_name, created_at FROM observations WHERE session_id = 'YOUR_SESSION_ID';
+```

+
+### Data Flow
+
+#### Memory Pipeline
+```
+Hook (stdin) → Database → Worker Service → SDK Processor → Database → Next Session Hook
+```
+
+1. **Input**: Claude Code sends tool execution data via stdin to hooks
+2. **Storage**: Hooks write observations to SQLite database
+3. **Processing**: Worker service reads observations, processes via SDK
+4. **Output**: Processed summaries written back to database
+5. **Retrieval**: Next session's context hook reads summaries from database
+
+#### Search Pipeline
+```
+Claude Request → MCP Server → SessionSearch Service → FTS5 Database → Search Results → Claude
+```
+
+1. **Query**: Claude uses MCP search tools (e.g., `search_observations`)
+2. **Search**: MCP server calls SessionSearch service with query parameters
+3. **FTS5**: Full-text search executes against FTS5 virtual tables
+4. **Format**: Results formatted as `search_result` blocks with citations
+5. **Return**: Claude receives citable search results for analysis

+```
+~/.claude-mem/              # Old location (no longer used)
+```
+
+### Plugin Configuration
+
+#### Hooks Configuration
+
+Hooks are configured in `plugin/hooks/hooks.json`:
+
+```json
+{
+  "SessionStart": {
+    "command": "${CLAUDE_PLUGIN_ROOT}/scripts/context-hook.js",
+    "timeout": 180000
+  },
+  "UserPromptSubmit": {
+    "command": "${CLAUDE_PLUGIN_ROOT}/scripts/new-hook.js",
+    "timeout": 60000
+  },
+  "PostToolUse": {
+    "command": "${CLAUDE_PLUGIN_ROOT}/scripts/save-hook.js",
+    "timeout": 180000
+  },
+  "Stop": {
+    "command": "${CLAUDE_PLUGIN_ROOT}/scripts/summary-hook.js",
+    "timeout": 60000
+  },
+  "SessionEnd": {
+    "command": "${CLAUDE_PLUGIN_ROOT}/scripts/cleanup-hook.js",
+    "timeout": 60000
+  }
+}
+```
+
+#### MCP Server Configuration
+
+The MCP search server is configured in `plugin/.mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "claude-mem-search": {
+      "type": "stdio",
+      "command": "${CLAUDE_PLUGIN_ROOT}/scripts/search-server.js"
+    }
+  }
+}
+```
+
+This registers the `claude-mem-search` server with Claude Code, making the 6 search tools available in all sessions. The server is automatically started when Claude Code launches and communicates via stdio transport.
+
+---
+
+## Development
+
+### Building from Source
+
+```bash
+# Clone repository
+git clone https://github.com/thedotmack/claude-mem.git
+cd claude-mem
+
+# Install dependencies
+npm install
+
+# Build all components
+npm run build
+```
+
+The build process:
+1. Compiles TypeScript to JavaScript using esbuild
+2. Creates standalone executables for each hook in `plugin/scripts/`
+3. Bundles MCP search server to `plugin/scripts/search-server.js`
+4. Bundles worker service to `plugin/scripts/worker-service.cjs`
+
+### Running Tests
+
+```bash
+# Run all tests
+npm test
+
+# Run specific test file
+node --test tests/session-lifecycle.test.ts
+```
+
+### Development Workflow
+
+1. Make changes to TypeScript source files
+2. Run `npm run build` to compile
+3. Test with `npm run test:context` or start Claude Code
+4. Check worker logs with `npm run worker:logs`
+
+### Adding New Features
+
+#### Adding a New Hook
+
+1. Create hook implementation in `src/hooks/your-hook.ts`
+2. Create entry point in `src/bin/hooks/your-hook.ts`
+3. Add to `plugin/hooks/hooks.json`
+4. Rebuild with `npm run build`
+
+#### Modifying Database Schema
+
+1. Add migration to `src/services/sqlite/migrations.ts`
+2. Update types in `src/services/sqlite/types.ts`
+3. Update database methods in `src/services/sqlite/HooksDatabase.ts`
+
+#### Extending SDK Prompts
+
+1. Modify prompts in `src/sdk/prompts.ts`
+2. Update parser in `src/sdk/parser.ts` to handle new XML structure
+3. Test with `npm test`
+
+---
+
+## Troubleshooting
+
+### Worker Service Issues
+
+**Problem**: Worker service not starting
+
+```bash
+# Check if PM2 is running
+pm2 status
+
+# Check worker logs
+npm run worker:logs
+
+# Restart worker
+npm run worker:restart
+
+# Full reset
+pm2 delete claude-mem-worker
+npm run worker:start
+```
+
+**Problem**: Port allocation failed
+
+```bash
+# Check if port file exists (v4.0+)
+cat ${CLAUDE_PLUGIN_ROOT}/data/worker.port
+
+# Manually specify port
+CLAUDE_MEM_WORKER_PORT=37500 npm run worker:start
+```
+
+### Hook Issues
+
+**Problem**: Hooks not firing
+
+```bash
+# Test context hook manually
+echo '{"session_id":"test-123","cwd":"'$(pwd)'","source":"startup"}' | node plugin/scripts/context-hook.js
+
+# Check hook permissions
+ls -la plugin/scripts/*.js
+
+# Verify hooks.json is valid
+cat plugin/hooks/hooks.json | jq .
+```
+
+**Problem**: Context not appearing
+
+```bash
+# Check if summaries exist
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM session_summaries;"
+
+# View recent sessions
+npm run test:context:verbose
+
+# Check database integrity
+sqlite3 ~/.claude-mem/claude-mem.db "PRAGMA integrity_check;"
+```
+
+### Database Issues
+
+**Problem**: Database locked
+
+```bash
+# Close all connections
+pm2 stop claude-mem-worker
+
+# Check for stale locks
+lsof ~/.claude-mem/claude-mem.db
+
+# Backup and recreate (nuclear option)
+cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup
+rm ~/.claude-mem/claude-mem.db
+npm run worker:start  # Will recreate schema
+```
+
+### Debugging
+
+Enable verbose logging:
+
+```bash
+# Set debug mode
+export DEBUG=claude-mem:*
+
+# View all logs
+npm run worker:logs
+```
+
+Check correlation IDs to trace observations through the pipeline:
+
+```bash
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT correlation_id, tool_name, created_at FROM observations WHERE session_id = 'YOUR_SESSION_ID' ORDER BY created_at;"
+```

+# Claude-Mem Architecture Refactor Plan
+
+## Core Purpose
+
+Create a lightweight, hook-driven memory system that captures important context during Claude Code sessions and makes it available in future sessions.
+
+**Principles:**
+- Hooks should be fast and non-blocking
+- SDK agent synthesizes observations, not just stores raw data
+- Storage should be simple and queryable
+- Users should never notice the memory system working
+
+---
+
+## Understanding the Foundation
+
+### What Claude Code Hooks Actually Do
+
+**SessionStart Hook:**
+- Runs when Claude Code starts or resumes
+- Can inject context via stdout (plain text) OR JSON `additionalContext`
+- This is how we show "What's new" to Claude
+
+**UserPromptSubmit Hook:**
+- Runs BEFORE Claude processes the user's message
+- Can inject context via stdout OR JSON `additionalContext`
+- This is where we initialize per-session tracking
+
+**PostToolUse Hook:**
+- Runs AFTER each tool completes successfully
+- Gets both tool input and output
+- Runs in PARALLEL with other matching hooks
+- This is where we observe what Claude is doing
+
+**Stop Hook:**
+- Runs when main agent finishes (NOT on user interrupt)
+- This is where we finalize the session
+- Summary should be structured responses that answer the following:
+  - What did user request?
+  - What did you investigate?
+  - What did you learn?
+  - What did you do?
+  - What's next?
+  - Files read
+  - Files edited
+  - Notes
+
+### How SDK Streaming Actually Works
+
+**Streaming Input Mode (what we need):**
+- Persistent session with AsyncGenerator
+- Can queue multiple messages
+- Supports interruption via `interrupt()` method
+- Natural multi-turn conversations
+- The SDK maintains conversation state
+
+**Critical insight:** We use "Streaming Input Mode" which creates ONE long-running SDK session per Claude Code session, not multiple short sessions.
+
+**Session ID Management:**
+- Session IDs change with each turn of the conversation
+- Must capture session ID from the initial system message
+- SDK worker needs to track session ID updates continuously, not just capture once
+- The first message in the response stream is a system init message with the session_id

+
+### What is the SDK agent's job?
+
+The SDK agent is a **synthesis engine**, not a data collector.
+
+It should:
+- Receive tool observations as they happen
+- Extract meaningful patterns and insights
+- Store atomic, searchable observations in SQLite
+- Synthesize a human-readable summary at the end
+
+It should NOT:
+- Store raw tool outputs
+- Try to capture everything
+- Make decisions about what Claude Code should do
+- Block or slow down the main session
+
+### Session Management Strategy
+
+**Built-in SDK Session Resumption:**
+
+The Agent SDK provides native session resumption capabilities. Instead of manually tracking and rebuilding session state, we can leverage the SDK's built-in features:
+
+```typescript
+// Resume a previous SDK session
+const resumedResponse = query({
+  prompt: "Continue where we left off",
+  options: {
+    resume: sdkSessionId  // Use the session ID captured from init message
+  }
+});
+```
+
+**When to use session resumption:**
+- User interrupts Claude Code and resumes later
+- SDK worker crashes and needs to restart
+- Long-running observations that span multiple Claude Code sessions
+
+**Session state tracking:**
+- Store SDK session ID in database when captured from init message
+- Mark sessions as 'active', 'completed', 'interrupted', or 'failed'
+- Use session status to determine whether to resume or start fresh
+
+### How hooks run in parallel
+
+PostToolUse hooks run in parallel. Handle this by:
+- Make SDK agent calls async and fire-and-forget
+- Use the observation_queue SQLite table to serialize observations
+- SDK worker polls this queue and processes observations sequentially
+
+### What if the user interrupts Claude Code?
+
+Stop hook doesn't run on interrupts. So:
+- Observations stay in queue
+- Next session continues where left off
+- Mark session as 'interrupted' after 24h of inactivity
+

+
+## Hook Implementation
+
+**IMPORTANT DISTINCTION:**
+
+There are TWO separate hook systems at play here:
+
+1. **Claude Code Hooks** - External command hooks configured in `~/.config/claude-code/settings.json`
+   - These hooks observe the MAIN Claude Code session
+   - They run as external commands (like `claude-mem save`)
+   - This is what we use to capture observations from the user's session
+
+2. **SDK Hooks** - Programmatic hooks configured in TypeScript code via `HookMatcher`
+   - These hooks would observe the MEMORY SDK agent's own tool usage
+   - They run as TypeScript callbacks within the SDK worker process
+   - We're NOT using these (yet) - they're a future enhancement
+
+**Our architecture:** Use Claude Code hooks (external commands) to observe the main session, and run a separate SDK worker process that doesn't need its own hooks.
+
+### 1. SessionStart Hook
+
+**Purpose:** Show user what happened in recent sessions
+
+**Claude Code Hook Config (in settings.json):**
+```json
+{
+  "hooks": {
+    "SessionStart": [{
+      "matcher": "startup",
+      "hooks": [{
+        "type": "command",
+        "command": "claude-mem context"
+      }]
+    }]
+  }
+}
+```
+
+**Command: `claude-mem context`**
+
+Flow:
+1. Read stdin JSON (session_id, cwd, source, etc.)
+2. If source !== "startup", exit immediately
+3. Extract project from cwd basename
+4. Query SQLite for recent summaries:
+   ```sql
+   SELECT summary, created_at
+   FROM session_summaries
+   WHERE project = ?
+   ORDER BY created_at_epoch DESC
+   LIMIT 10
+   ```
+5. Format results as human-readable text
+6. Output to stdout (Claude Code automatically injects this)
+7. Exit with code 0
+
+### 2. UserPromptSubmit Hook
+
+**Purpose:** Initialize SDK memory session in background
+
+**Hook config:**
+```json
+{
+  "hooks": {
+    "UserPromptSubmit": [{
+      "hooks": [{
+        "type": "command",
+        "command": "claude-mem new"
+      }]
+    }]
+  }
+}
+```
+
+**Command: `claude-mem new`**
+
+Flow:
+1. Read stdin JSON (session_id, prompt, cwd, etc.)
+2. Extract project from cwd
+3. Create SDK session record in database
+4. Start SDK session with initialization prompt in background process
+5. Save SDK session ID to database
+6. Output: `{"continue": true, "suppressOutput": true}`
+7. Exit immediately (SDK runs in background daemon/process)
+
+**The Background SDK Process:**
+
+The SDK session should run as a detached background process:
+```typescript
+// In claude-mem new
+const child = spawn('claude-mem', ['sdk-worker', session_id], {
+  detached: true,
+  stdio: 'ignore'
+});
+child.unref();
+```
+
+The SDK worker:
+```typescript
+// claude-mem sdk-worker <session_id>
+import { query } from '@anthropic-ai/agent-sdk';
+import type { Query, UserMessage } from '@anthropic-ai/agent-sdk';
+
+async function runSDKWorker(sessionId: string) {
+  const session = await loadSessionFromDB(sessionId);
+
+  // Track the SDK session ID from the init message
+  let sdkSessionId: string | undefined;
+  const abortController = new AbortController();
+
+  // Message generator yields UserMessage objects (role + content)
+  // This matches the SDK's expected format for streaming input mode
+  async function* messageGenerator(): AsyncIterable<UserMessage> {
+    // Initial prompt
+    yield {
+      role: "user",
+      content: buildInitPrompt(session)
+    };
+
+    // Then listen for queued observations
+    while (session.status === 'active' && !abortController.signal.aborted) {
+      const observations = await pollObservationQueue(session.sdk_session_id);
+
+      for (const obs of observations) {
+        yield {
+          role: "user",
+          content: buildObservationPrompt(obs)
+        };
+        markObservationProcessed(obs.id);
+      }
+
+      await sleep(1000); // Poll every second
+    }
+  }
+
+  // Run SDK session with proper streaming interface
+  // The query function signature: query({ prompt, options }): Query
+  const response: Query = query({
+    prompt: messageGenerator(), // AsyncIterable<UserMessage>
+    options: {
+      model: 'claude-sonnet-4-5', // Use documented model name
+      disallowedTools: ['Glob', 'Grep', 'ListMcpResourcesTool', 'WebSearch'], // More efficient than filtering in hooks
+      maxTurns: 1000,
+      cwd: session.cwd,
+      abortController: abortController
+    }
+  });
+
+  try {
+    // Consume responses from the Query AsyncGenerator
+    for await (const msg of response) {
+      // Capture session ID from system init message
+      if (msg.type === 'system' && msg.subtype === 'init') {
+        sdkSessionId = msg.session_id;
+        console.log(`SDK session started with ID: ${sdkSessionId}`);
+        // Store SDK session ID in database for potential resumption
+        await updateSDKSessionId(session.id, sdkSessionId);
+      }
+
+      if (msg.type === 'text') {
+        // Use an XML parser library (e.g., fast-xml-parser or similar) to parse observations and summaries
+        // Parse <observation> blocks and call storeObservation(session_id, project, type, text)
+        // Parse <summary> blocks, extract all 8 fields, format and call storeSummary(session_id, project, text)
+
+        parseAndStoreObservations(msg.content, session);
+        parseAndStoreSummary(msg.content, session);
+      }
+    }
+  } catch (error) {
+    if (abortController.signal.aborted) {
+      console.log('SDK worker interrupted gracefully');
+    } else {
+      console.error('SDK worker error:', error);
+      await markSessionFailed(session.id, error);
+    }
+  } finally {
+    await cleanupSession(session.id);
+  }
+}
+
+// Note: Query and UserMessage types are imported from '@anthropic-ai/agent-sdk'
+// Query extends AsyncGenerator and provides interrupt() and setPermissionMode() methods
+// UserMessage has the shape: { role: "user", content: string }
+```
+
+### 3. PostToolUse Hook
+
+**Purpose:** Queue tool observations for SDK processing
+
+**Hook config:**
+```json
+{
+  "hooks": {
+    "PostToolUse": [{
+      "matcher": "*",
+      "hooks": [{
+        "type": "command",
+        "command": "claude-mem save"
+      }]
+    }]
+  }
+}
+```
+
+**Command: `claude-mem save`**
+
+Flow:
+1. Read stdin JSON (tool_name, tool_input, tool_output, etc.)
+2. Find active SDK session for this project
+3. Insert observation into queue:
+   ```sql
+   INSERT INTO observation_queue
+   (sdk_session_id, tool_name, tool_input, tool_output, created_at_epoch)
+   VALUES (?, ?, ?, ?, ?)
+   ```
+4. Output: `{"continue": true, "suppressOutput": true}`
+5. Exit immediately
+
+**Observation Filtering:**
+
+Tool filtering is now handled at the SDK level (see SDK Worker section) using `disallowedTools` option. The hook no longer needs to filter tools manually - all tool observations that reach the hook are already relevant.
+
+However, you may still want to skip certain tools for performance reasons:
+```typescript
+// Optional: Skip very frequent or low-value tools
+const SKIP_TOOLS = new Set(['TodoWrite', 'ListMcpResourcesTool']);
+
+if (SKIP_TOOLS.has(tool_name)) {
+  console.log('{"continue": true, "suppressOutput": true}');
+  process.exit(0);
+}
+```
+
+**Note:** The SDK worker uses `disallowedTools: ['Glob', 'Grep', 'ListMcpResourcesTool', 'WebSearch']` which is more efficient than hook-level filtering because it prevents the SDK agent from using these tools entirely.
+
+### 4. Stop Hook
+
+**Purpose:** Signal SDK to finalize and generate summary
+
+**Hook config:**
+```json
+{
+  "hooks": {
+    "Stop": [{
+      "hooks": [{
+        "type": "command",
+        "command": "claude-mem summary"
+      }]
+    }]
+  }
+}
+```
+
+**Command: `claude-mem summary`**
+
+Flow:
+1. Read stdin JSON (session_id, cwd, etc.)
+2. Find active SDK session
+3. Insert special "FINALIZE" message into observation queue:
+   ```sql
+   INSERT INTO observation_queue
+   (sdk_session_id, tool_name, tool_input, tool_output, created_at_epoch)
+   VALUES (?, 'FINALIZE', '{}', '{}', ?)
+   ```
+4. Output: `{"continue": true, "suppressOutput": true}`
+5. Exit immediately
+
+**SDK Worker Handling:**
+
+When SDK worker sees FINALIZE message:
+```typescript
+if (obs.tool_name === 'FINALIZE') {
+  yield {
+    type: "user",
+    message: {
+      role: "user",
+      content: buildFinalizePrompt(session)
+    }
+  };
+
+  // Wait for SDK to finish processing
+  await waitForSDKCompletion();
+
+  // Update session status
+  await markSessionCompleted(session.id);
+
+  // Exit worker
+  break;
+}
+```
+

+
+## SDK Agent Prompts
+
+### Initialization Prompt
+
+```typescript
+function buildInitPrompt(project: string, sessionId: string, userPrompt: string): string {
+  return `You are a memory assistant for the "${project}" project.
+
+SESSION CONTEXT
+---------------
+Session ID: ${sessionId}
+User's Goal: ${userPrompt}
+Date: ${new Date().toISOString().split('T')[0]}
+
+YOUR ROLE
+---------
+You will observe tool executions during this Claude Code session. Your job is to:
+
+1. Extract meaningful insights (not just raw data)
+2. Store atomic observations in SQLite
+3. Focus on: key decisions, patterns discovered, problems solved, technical insights
+
+WHAT TO CAPTURE
+----------------
+✓ Architecture decisions (e.g., "chose PostgreSQL over MongoDB for ACID guarantees")
+✓ Bug fixes (e.g., "fixed race condition in auth middleware by adding mutex")
+✓ New features (e.g., "implemented JWT refresh token flow")
+✓ Refactorings (e.g., "extracted validation logic into separate service")
+✓ Discoveries (e.g., "found that API rate limit is 100 req/min")
+
+✗ NOT routine operations (reading files, listing directories)
+✗ NOT work-in-progress (only completed work)
+✗ NOT obvious facts (e.g., "TypeScript file has types")
+
+HOW TO STORE OBSERVATIONS
+--------------------------
+When you identify something worth remembering, output your observation in this EXACT XML format:
+
+\`\`\`xml
+<observation>
+  <type>feature</type>
+  <text>Implemented JWT token refresh flow with 7-day expiry</text>
+</observation>
+\`\`\`
+
+Valid types: decision, bugfix, feature, refactor, discovery
+
+Structure requirements:
+- <observation> is the root element
+- <type> must be one of the 5 valid types (single word)
+- <text> contains your concise observation (one sentence preferred)
+- No additional fields or nesting
+
+The SDK worker will parse all <observation> blocks from your response using regex and store them in SQLite.
+
+You can include your reasoning before or after the observation block, or just output the observation by itself.
+
+EXAMPLE
+-------
+Bad: "Read src/auth.ts file"
+Good: "Implemented JWT token refresh flow with 7-day expiry"
+
+Wait for tool observations. Acknowledge this message briefly.`;
+}
+```
+
+### Observation Prompt
+
+```typescript
+function buildObservationPrompt(obs: Observation): string {
+  return `TOOL OBSERVATION
+================
+Tool: ${obs.tool_name}
+Time: ${new Date(obs.created_at_epoch).toISOString()}
+
+Input:
+${JSON.stringify(JSON.parse(obs.tool_input), null, 2)}
+
+Output:
+${JSON.stringify(JSON.parse(obs.tool_output), null, 2)}
+
+ANALYSIS TASK
+-------------
+1. Does this observation contain something worth remembering?
+2. If YES: Output the observation in this EXACT XML format:
+
+   \`\`\`xml
+   <observation>
+     <type>feature</type>
+     <text>Your concise observation here</text>
+   </observation>
+   \`\`\`
+
+   Requirements:
+   - Use one of these types: decision, bugfix, feature, refactor, discovery
+   - Keep text concise (one sentence preferred)
+   - No markdown formatting inside <text>
+   - No additional XML fields
+
+3. If NO: Just acknowledge and wait for next observation
+
+Remember: Quality over quantity. Only store meaningful insights.`;
+}
+```
+
+### Finalization Prompt
+
+```typescript
+function buildFinalizePrompt(session: SDKSession): string {
+  return `SESSION ENDING
+==============
+The Claude Code session is finishing.
+
+FINAL TASK
+----------
+1. Review the observations you've stored this session
+2. Generate a structured summary that answers these questions:
+   - What did user request?
+   - What did you investigate?
+   - What did you learn?
+   - What did you do?
+   - What's next?
+   - Files read
+   - Files edited
+   - Notes
+
+3. Generate the structured summary and output it in this EXACT XML format:
+
+\`\`\`xml
+<summary>
+  <request>Implement JWT authentication system</request>
+  <investigated>Existing auth middleware, session management, token storage patterns</investigated>
+  <learned>Current system uses session cookies; no JWT support; race condition in middleware</learned>
+  <completed>Implemented JWT token + refresh flow with 7-day expiry; fixed race condition with mutex; added token validation middleware</completed>
+  <next_steps>Add token revocation API endpoint; write integration tests</next_steps>
+  <files_read>
+    <file>src/auth.ts</file>
+    <file>src/middleware/session.ts</file>
+    <file>src/types/user.ts</file>
+  </files_read>
+  <files_edited>
+    <file>src/auth.ts</file>
+    <file>src/middleware/auth.ts</file>
+    <file>src/routes/auth.ts</file>
+  </files_edited>
+  <notes>Token secret stored in .env; refresh tokens use rotation strategy</notes>
+</summary>
+\`\`\`
+
+Structure requirements:
+- <summary> is the root element
+- All 8 child elements are REQUIRED: request, investigated, learned, completed, next_steps, files_read, files_edited, notes
+- <files_read> and <files_edited> must contain <file> child elements (one per file)
+- If no files were read/edited, use empty tags: <files_read></files_read>
+- Text fields can be multiple sentences but avoid markdown formatting
+- Use underscores in element names: next_steps, files_read, files_edited
+
+The SDK worker will parse the <summary> block and extract all fields to store in SQLite.
+
+Generate the summary now in the required XML format.`;
+}
+```
+
+---
+
+## Hook Commands Architecture
+
+All four hook commands (`claude-mem context`, `claude-mem new`, `claude-mem save`, `claude-mem summary`) are implemented as standalone TypeScript functions that:
+
+1. **Use bun:sqlite directly** - No spawning child processes or CLI subcommands
+2. **Are self-contained** - Each hook has all the logic it needs
+3. **Share a common database layer** - Import from shared `db.ts` module
+4. **Never call other claude-mem commands** - All functionality via direct library calls
+
+```typescript
+// Example structure
+import { Database } from 'bun:sqlite';
+
+export function contextHook(stdin: HookInput) {
+  const db = new Database('~/.claude-mem/db.sqlite');
+  // Query and return context directly
+  const summaries = db.query('SELECT ...').all();
+  console.log(formatContext(summaries));
+  db.close();
+}
+
+export function saveHook(stdin: HookInput) {
+  const db = new Database('~/.claude-mem/db.sqlite');
+  // Insert observation directly
+  db.run('INSERT INTO observation_queue ...', params);
+  db.close();
+  console.log('{"continue": true, "suppressOutput": true}');
+}
+```
+
+**Key principle:** Hooks are fast, synchronous database operations. The SDK worker process is where async/complex logic happens.
+
+---
+
+## Background Process Management
+
+The `claude-mem save` hook just queues observations - processing happens in the background SDK worker process that polls the queue continuously.
+
+The SDK worker is spawned by `claude-mem new` as a detached process and runs for the duration of the Claude Code session.
+
+Benefits:
+- Works on all platforms (no systemd/launchd needed)
+- Self-contained (spawned and managed by claude-mem itself)
+- Simple state management (all state in SQLite)
+
+---
+
+## Advanced SDK Features
+
+### Permission Integration (Future Enhancement)
+
+The SDK provides a permission system that could be integrated with memory for context-aware decisions:
+
+```typescript
+canUseTool: async (toolName, input) => {
+  // Check memory for previous decisions about this tool/context
+  const previousDecisions = await queryMemoryForTool(toolName, input);
+
+  if (previousDecisions.shouldAllow) {
+    return {
+      behavior: "allow",
+      updatedInput: input
+    };
+  }
+
+  return {
+    behavior: "ask_user",
+    message: `This tool was previously flagged. Allow anyway?`
+  };
+}
+```
+
+This could enable:
+- Learning from previous tool use patterns
+- Automatically allowing/denying based on historical context
+- Providing smart defaults based on project-specific patterns
+
+**Implementation priority:** Low (add after core functionality is stable)
+
+### SDK Hook Configuration (Alternative to Claude Code Hooks)
+
+Instead of using external command hooks via Claude Code settings.json, the SDK supports native hook configuration:
+
+```typescript
+import { HookMatcher } from '@anthropic-ai/agent-sdk';
+
+const response = query({
+  prompt: messageGenerator(),
+  options: {
+    hooks: {
+      'PreToolUse': [
+        HookMatcher(matcher='Bash', hooks=[validateBashCommand]),
+        HookMatcher(hooks=[logToolUse])  // Applies to all tools
+      ],
+      'PostToolUse': [
+        HookMatcher(hooks=[captureObservation])
+      ]
+    }
+  }
+});
+
+type HookCallback = (
+  input: HookInput,
+  toolUseID: string | undefined,
+  options: { signal: AbortSignal }
+) => Promise<HookJSONOutput>;
+```
+
+**When to use SDK hooks vs Claude Code hooks:**
+- **Claude Code hooks**: For integrating with the main Claude Code session (our current approach)
+- **SDK hooks**: For controlling the memory agent's own tool usage (future enhancement)
+
+**Implementation priority:** Medium (could simplify architecture, but adds complexity to migration)
+
+---
+
+## Error Handling
+
+**SDK worker failures:**
+- Each observation processing is atomic
+- Failed observations stay in queue
+- Next worker run retries
+- After 3 failures, mark observation as skipped
+- Use AbortController for graceful cancellation
+
+**Abort signal handling:**
+```typescript
+try {
+  for await (const msg of response) {
+    if (abortController.signal.aborted) {
+      throw new Error('Aborted');
+    }
+    // Process message
+  }
+} catch (error) {
+  if (abortController.signal.aborted) {
+    // Clean shutdown
+    await response.interrupt();
+  } else {
+    // Actual error
+    throw error;
+  }
+}
+```
+
+**Database corruption:**
+- SQLite with WAL mode (write-ahead logging)
+- Regular backups to ~/.claude-mem/backups/
+- Automatic recovery from backups
+
+**SDK API failures:**
+- Retry with exponential backoff
+- Don't block main Claude Code session
+- Log errors for debugging
+- Mark session as 'failed' after max retries
+
+---
+
+## Implementation Order
+
+1. **Database setup** - Create tables and migration scripts
+2. **Hook commands** - Implement the 4 hook commands (context, new, save, summary)
+3. **SDK worker** - Implement the background worker process with response parsing
+4. **SDK prompts** - Wire up the prompts and message generator
+5. **Test end-to-end** - Run a real Claude Code session and verify it works
+
+Start simple. Get one hook working before moving to the next. Don't try to build everything at once.
+
+**Note:** MCP is only used for retrieval (when Claude Code needs to access stored memories), not for storage. The SDK agent stores data by outputting specially formatted text that the SDK worker parses and writes to SQLite.
+
+### SDK Import Verification
+
+Before implementing, verify the SDK exports match your usage:
+
+```typescript
+// Required imports from @anthropic-ai/agent-sdk
+import { query } from '@anthropic-ai/agent-sdk';
+import type { Query, UserMessage, Options } from '@anthropic-ai/agent-sdk';
+
+// Verify the query function signature:
+// function query(options: { prompt: string | AsyncIterable<UserMessage>; options?: Options }): Query
+
+// Verify Query type:
+// interface Query extends AsyncGenerator<SDKMessage, void> {
+//   interrupt(): Promise<void>;
+//   setPermissionMode(mode: PermissionMode): Promise<void>;
+// }
+
+// Verify UserMessage type:
+// type UserMessage = { role: "user"; content: string }
+```
+
+If the SDK exports differ from this structure, adjust the implementation accordingly. The SDK documentation should be the source of truth.
+
+---
+
+## Key Corrections from Agent SDK Documentation
+
+This refactor plan has been updated to align with the official Agent SDK documentation. Key corrections include:
+
+### 1. Session ID Management
+- **Before:** Captured session ID once in UserPromptSubmit hook
+- **After:** Capture from system init message and track updates continuously
+- **Why:** Session IDs change with each conversation turn
+
+### 2. Hook Configuration
+- **Before:** Mixed up SDK hook format with Claude Code hook format
+- **After:** Clarified that Claude Code uses settings.json format (external commands); SDK uses TypeScript HookMatcher (programmatic callbacks)
+- **Why:** Two separate hook systems with different purposes and configuration methods
+- **Our approach:** Use Claude Code hooks to observe the main session; SDK hooks are future enhancement
+
+### 3. Message Generator and Query Interface
+- **Before:** Custom SDKMessage type with nested message structure
+- **After:** Simple UserMessage type `{ role: "user", content: string }` yielded from AsyncIterable
+- **Why:** SDK expects AsyncIterable<UserMessage>, not a custom wrapper format
+- **Query type:** Properly typed as `Query` which extends AsyncGenerator with interrupt() and setPermissionMode()
+
+### 4. Tool Filtering
+- **Before:** Filter "boring tools" in PostToolUse hook
+- **After:** Use SDK's `disallowedTools` option in query configuration
+- **Why:** More efficient to prevent SDK from using tools entirely
+
+### 5. Model Identifier
+- **Before:** Used `claude-haiku-4-5-20251001` (undocumented)
+- **After:** Use `claude-sonnet-4-5` (documented model name)
+- **Why:** Stick to documented model identifiers for stability
+
+### 6. Error Handling
+- **Before:** Custom error handling without SDK features
+- **After:** Use AbortController and response.interrupt() for graceful cancellation
+- **Why:** SDK provides built-in cancellation mechanisms
+
+### 7. Session Resumption
+- **Before:** Manual session state reconstruction
+- **After:** Leverage SDK's built-in `resume: sessionId` option
+- **Why:** SDK already handles session resumption
+
+### Future Enhancements to Consider
+
+1. **Permission integration** - Use canUseTool callback to make memory-aware decisions
+2. **SDK native hooks** - Replace external command hooks with SDK HookMatcher
+3. **Better session recovery** - Use SDK resumption for interrupted sessions
+
+These corrections ensure our implementation follows Agent SDK best practices and avoids reinventing functionality the SDK already provides.
+
+---
+
+## Architecture Validation Summary
+
+This plan has been validated against the official Agent SDK documentation and confirmed to be architecturally sound.
+
+### ✅ Validated Design Decisions
+
+1. **Hook System Usage** - Correctly uses Claude Code external command hooks for observation; SDK programmatic hooks reserved for future enhancement
+2. **Query Function Interface** - Properly implements AsyncIterable<UserMessage> for streaming input mode
+3. **Session Management** - Leverages SDK's built-in session resumption instead of manual state reconstruction
+4. **Tool Filtering** - Uses SDK's `disallowedTools` option for efficiency
+5. **Error Handling** - Implements AbortController and interrupt() for graceful cancellation
+6. **Separation of Concerns** - Clean isolation between main Claude Code session and background SDK worker
+
+### 🎯 Architecture Strengths
+
+- **Non-blocking** - Hooks are fast database operations; complex logic happens in background
+- **Queue-based** - Handles parallel hook execution correctly via observation_queue table
+- **Fault-tolerant** - Failed observations stay in queue for retry; graceful degradation
+- **Platform-agnostic** - No dependency on systemd/launchd; works everywhere
+- **Type-safe** - Uses official SDK TypeScript types throughout
+
+### 📋 Pre-Implementation Checklist
+
+Before starting implementation, verify:
+
+1. [ ] Agent SDK installed and accessible: `@anthropic-ai/agent-sdk`
+2. [ ] Verify SDK exports match expected structure (query, Query, UserMessage types)
+3. [ ] SQLite database location decided: `~/.claude-mem/db.sqlite`
+4. [ ] Claude Code settings.json hook configuration tested
+5. [ ] Background process spawning works on target platform (test detached process)
+
+### 🚀 Ready for Implementation
+
+The architecture is validated and ready for implementation. Follow the phased approach:
+
+1. Database setup first (get schema working with bun:sqlite)
+2. Implement hooks one at a time (start with `context`, then `save`)
+3. Build SDK worker with simple message generator
+4. Test end-to-end with a real Claude Code session
+5. Iterate and refine based on real-world usage
+
+**Remember:** Start simple, get one piece working, then build on it. Don't try to implement everything at once.

+- **Exit code 2**: Blocking error. `stderr` is fed back to Claude to process automatically [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output)  
+- **Other exit codes**: Non-blocking error. `stderr` is shown to the user and execution continues [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output)

+## Per-Hook Event Behavior [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output)
+
+| Hook Event | Exit Code 2 Behavior |
+|------------|---------------------|
+| `PreToolUse` | Blocks the tool call, shows stderr to Claude [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `PostToolUse` | Shows stderr to Claude (tool already ran) [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `Notification` | N/A, shows stderr to user only [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `UserPromptSubmit` | Blocks prompt processing, erases prompt, shows stderr to user only [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `Stop` | Blocks stoppage, shows stderr to Claude [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `SubagentStop` | Blocks stoppage, shows stderr to Claude subagent [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `PreCompact` | N/A, shows stderr to user only [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `SessionStart` | N/A, shows stderr to user only [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+| `SessionEnd` | N/A, shows stderr to user only [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output) |
+
+## Quick Reference
+
+- **Success**: `process.exit(0)` - Operation completed successfully
+- **Block & feedback**: `process.exit(2)` - Block operation and give Claude feedback via stderr  
+- **Non-blocking error**: `process.exit(1)` - Show error to user but continue execution
+
+**Important**: Claude Code does not see stdout if the exit code is 0, except for the `UserPromptSubmit` hook where stdout is injected as context [(1)](https://docs.claude.com/en/docs/claude-code/hooks#hook-output)

+# Hooks reference
+
+> This page provides reference documentation for implementing hooks in Claude Code.
+
+<Tip>
+  For a quickstart guide with examples, see [Get started with Claude Code hooks](/en/docs/claude-code/hooks-guide).
+</Tip>
+
+## Configuration
+
+Claude Code hooks are configured in your [settings files](/en/docs/claude-code/settings):
+
+* `~/.claude/settings.json` - User settings
+* `.claude/settings.json` - Project settings
+* `.claude/settings.local.json` - Local project settings (not committed)
+* Enterprise managed policy settings
+
+### Structure
+
+Hooks are organized by matchers, where each matcher can have multiple hooks:
+
+```json  theme={null}
+{
+  "hooks": {
+    "EventName": [
+      {
+        "matcher": "ToolPattern",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "your-command-here"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+* **matcher**: Pattern to match tool names, case-sensitive (only applicable for
+  `PreToolUse` and `PostToolUse`)
+  * Simple strings match exactly: `Write` matches only the Write tool
+  * Supports regex: `Edit|Write` or `Notebook.*`
+  * Use `*` to match all tools. You can also use empty string (`""`) or leave
+    `matcher` blank.
+* **hooks**: Array of commands to execute when the pattern matches
+  * `type`: Currently only `"command"` is supported
+  * `command`: The bash command to execute (can use `$CLAUDE_PROJECT_DIR`
+    environment variable)
+  * `timeout`: (Optional) How long a command should run, in seconds, before
+    canceling that specific command.
+
+For events like `UserPromptSubmit`, `Notification`, `Stop`, and `SubagentStop`
+that don't use matchers, you can omit the matcher field:
+
+```json  theme={null}
+{
+  "hooks": {
+    "UserPromptSubmit": [
+      {
+        "hooks": [
+          {
+            "type": "command",
+            "command": "/path/to/prompt-validator.py"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### Project-Specific Hook Scripts
+
+You can use the environment variable `CLAUDE_PROJECT_DIR` (only available when
+Claude Code spawns the hook command) to reference scripts stored in your project,
+ensuring they work regardless of Claude's current directory:
+
+```json  theme={null}
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "matcher": "Write|Edit",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/check-style.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### Plugin hooks
+
+[Plugins](/en/docs/claude-code/plugins) can provide hooks that integrate seamlessly with your user and project hooks. Plugin hooks are automatically merged with your configuration when plugins are enabled.
+
+**How plugin hooks work**:
+
+* Plugin hooks are defined in the plugin's `hooks/hooks.json` file or in a file given by a custom path to the `hooks` field.
+* When a plugin is enabled, its hooks are merged with user and project hooks
+* Multiple hooks from different sources can respond to the same event
+* Plugin hooks use the `${CLAUDE_PLUGIN_ROOT}` environment variable to reference plugin files
+
+**Example plugin hook configuration**:
+
+```json  theme={null}
+{
+  "description": "Automatic code formatting",
+  "hooks": {
+    "PostToolUse": [
+      {
+        "matcher": "Write|Edit",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "${CLAUDE_PLUGIN_ROOT}/scripts/format.sh",
+            "timeout": 30
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+<Note>
+  Plugin hooks use the same format as regular hooks with an optional `description` field to explain the hook's purpose.
+</Note>
+
+<Note>
+  Plugin hooks run alongside your custom hooks. If multiple hooks match an event, they all execute in parallel.
+</Note>
+
+**Environment variables for plugins**:
+
+* `${CLAUDE_PLUGIN_ROOT}`: Absolute path to the plugin directory
+* `${CLAUDE_PROJECT_DIR}`: Project root directory (same as for project hooks)
+* All standard environment variables are available
+
+See the [plugin components reference](/en/docs/claude-code/plugins-reference#hooks) for details on creating plugin hooks.
+
+## Hook Events
+
+### PreToolUse
+
+Runs after Claude creates tool parameters and before processing the tool call.
+
+**Common matchers:**
+
+* `Task` - Subagent tasks (see [subagents documentation](/en/docs/claude-code/sub-agents))
+* `Bash` - Shell commands
+* `Glob` - File pattern matching
+* `Grep` - Content search
+* `Read` - File reading
+* `Edit` - File editing
+* `Write` - File writing
+* `WebFetch`, `WebSearch` - Web operations
+
+### PostToolUse
+
+Runs immediately after a tool completes successfully.
+
+Recognizes the same matcher values as PreToolUse.
+
+### Notification
+
+Runs when Claude Code sends notifications. Notifications are sent when:
+
+1. Claude needs your permission to use a tool. Example: "Claude needs your
+   permission to use Bash"
+2. The prompt input has been idle for at least 60 seconds. "Claude is waiting
+   for your input"
+
+### UserPromptSubmit
+
+Runs when the user submits a prompt, before Claude processes it. This allows you
+to add additional context based on the prompt/conversation, validate prompts, or
+block certain types of prompts.
+
+### Stop
+
+Runs when the main Claude Code agent has finished responding. Does not run if
+the stoppage occurred due to a user interrupt.
+
+### SubagentStop
+
+Runs when a Claude Code subagent (Task tool call) has finished responding.
+
+### PreCompact
+
+Runs before Claude Code is about to run a compact operation.
+
+**Matchers:**
+
+* `manual` - Invoked from `/compact`
+* `auto` - Invoked from auto-compact (due to full context window)
+
+### SessionStart
+
+Runs when Claude Code starts a new session or resumes an existing session (which
+currently does start a new session under the hood). Useful for loading in
+development context like existing issues or recent changes to your codebase.
+
+**Matchers:**
+
+* `startup` - Invoked from startup
+* `resume` - Invoked from `--resume`, `--continue`, or `/resume`
+* `clear` - Invoked from `/clear`
+* `compact` - Invoked from auto or manual compact.
+
+### SessionEnd
+
+Runs when a Claude Code session ends. Useful for cleanup tasks, logging session
+statistics, or saving session state.
+
+The `reason` field in the hook input will be one of:
+
+* `clear` - Session cleared with /clear command
+* `logout` - User logged out
+* `prompt_input_exit` - User exited while prompt input was visible
+* `other` - Other exit reasons
+
+## Hook Input
+
+Hooks receive JSON data via stdin containing session information and
+event-specific data:
+
+```typescript  theme={null}
+{
+  // Common fields
+  session_id: string
+  transcript_path: string  // Path to conversation JSON
+  cwd: string              // The current working directory when the hook is invoked
+
+  // Event-specific fields
+  hook_event_name: string
+  ...
+}
+```
+
+### PreToolUse Input
+
+The exact schema for `tool_input` depends on the tool.
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "cwd": "/Users/...",
+  "hook_event_name": "PreToolUse",
+  "tool_name": "Write",
+  "tool_input": {
+    "file_path": "/path/to/file.txt",
+    "content": "file content"
+  }
+}
+```
+
+### PostToolUse Input
+
+The exact schema for `tool_input` and `tool_response` depends on the tool.
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "cwd": "/Users/...",
+  "hook_event_name": "PostToolUse",
+  "tool_name": "Write",
+  "tool_input": {
+    "file_path": "/path/to/file.txt",
+    "content": "file content"
+  },
+  "tool_response": {
+    "filePath": "/path/to/file.txt",
+    "success": true
+  }
+}
+```
+
+### Notification Input
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "cwd": "/Users/...",
+  "hook_event_name": "Notification",
+  "message": "Task completed successfully"
+}
+```
+
+### UserPromptSubmit Input
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "cwd": "/Users/...",
+  "hook_event_name": "UserPromptSubmit",
+  "prompt": "Write a function to calculate the factorial of a number"
+}
+```
+
+### Stop and SubagentStop Input
+
+`stop_hook_active` is true when Claude Code is already continuing as a result of
+a stop hook. Check this value or process the transcript to prevent Claude Code
+from running indefinitely.
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "~/.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "hook_event_name": "Stop",
+  "stop_hook_active": true
+}
+```
+
+### PreCompact Input
+
+For `manual`, `custom_instructions` comes from what the user passes into
+`/compact`. For `auto`, `custom_instructions` is empty.
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "~/.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "hook_event_name": "PreCompact",
+  "trigger": "manual",
+  "custom_instructions": ""
+}
+```
+
+### SessionStart Input
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "~/.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "hook_event_name": "SessionStart",
+  "source": "startup"
+}
+```
+
+### SessionEnd Input
+
+```json  theme={null}
+{
+  "session_id": "abc123",
+  "transcript_path": "~/.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
+  "cwd": "/Users/...",
+  "hook_event_name": "SessionEnd",
+  "reason": "exit"
+}
+```
+
+## Hook Output
+
+There are two ways for hooks to return output back to Claude Code. The output
+communicates whether to block and any feedback that should be shown to Claude
+and the user.
+
+### Simple: Exit Code
+
+Hooks communicate status through exit codes, stdout, and stderr:
+
+* **Exit code 0**: Success. `stdout` is shown to the user in transcript mode
+  (CTRL-R), except for `UserPromptSubmit` and `SessionStart`, where stdout is
+  added to the context.
+* **Exit code 2**: Blocking error. `stderr` is fed back to Claude to process
+  automatically. See per-hook-event behavior below.
+* **Other exit codes**: Non-blocking error. `stderr` is shown to the user and
+  execution continues.
+
+<Warning>
+  Reminder: Claude Code does not see stdout if the exit code is 0, except for
+  the `UserPromptSubmit` hook where stdout is injected as context.
+</Warning>
+
+#### Exit Code 2 Behavior
+
+| Hook Event         | Behavior                                                           |
+| ------------------ | ------------------------------------------------------------------ |
+| `PreToolUse`       | Blocks the tool call, shows stderr to Claude                       |
+| `PostToolUse`      | Shows stderr to Claude (tool already ran)                          |
+| `Notification`     | N/A, shows stderr to user only                                     |
+| `UserPromptSubmit` | Blocks prompt processing, erases prompt, shows stderr to user only |
+| `Stop`             | Blocks stoppage, shows stderr to Claude                            |
+| `SubagentStop`     | Blocks stoppage, shows stderr to Claude subagent                   |
+| `PreCompact`       | N/A, shows stderr to user only                                     |
+| `SessionStart`     | N/A, shows stderr to user only                                     |
+| `SessionEnd`       | N/A, shows stderr to user only                                     |
+
+### Advanced: JSON Output
+
+Hooks can return structured JSON in `stdout` for more sophisticated control:
+
+#### Common JSON Fields
+
+All hook types can include these optional fields:
+
+```json  theme={null}
+{
+  "continue": true, // Whether Claude should continue after hook execution (default: true)
+  "stopReason": "string", // Message shown when continue is false
+
+  "suppressOutput": true, // Hide stdout from transcript mode (default: false)
+  "systemMessage": "string" // Optional warning message shown to the user
+}
+```
+
+If `continue` is false, Claude stops processing after the hooks run.
+
+* For `PreToolUse`, this is different from `"permissionDecision": "deny"`, which
+  only blocks a specific tool call and provides automatic feedback to Claude.
+* For `PostToolUse`, this is different from `"decision": "block"`, which
+  provides automated feedback to Claude.
+* For `UserPromptSubmit`, this prevents the prompt from being processed.
+* For `Stop` and `SubagentStop`, this takes precedence over any
+  `"decision": "block"` output.
+* In all cases, `"continue" = false` takes precedence over any
+  `"decision": "block"` output.
+
+`stopReason` accompanies `continue` with a reason shown to the user, not shown
+to Claude.
+
+#### `PreToolUse` Decision Control
+
+`PreToolUse` hooks can control whether a tool call proceeds.
+
+* `"allow"` bypasses the permission system. `permissionDecisionReason` is shown
+  to the user but not to Claude.
+* `"deny"` prevents the tool call from executing. `permissionDecisionReason` is
+  shown to Claude.
+* `"ask"` asks the user to confirm the tool call in the UI.
+  `permissionDecisionReason` is shown to the user but not to Claude.
+
+```json  theme={null}
+{
+  "hookSpecificOutput": {
+    "hookEventName": "PreToolUse",
+    "permissionDecision": "allow" | "deny" | "ask",
+    "permissionDecisionReason": "My reason here"
+  }
+}
+```
+
+<Note>
+  The `decision` and `reason` fields are deprecated for PreToolUse hooks.
+  Use `hookSpecificOutput.permissionDecision` and
+  `hookSpecificOutput.permissionDecisionReason` instead. The deprecated fields
+  `"approve"` and `"block"` map to `"allow"` and `"deny"` respectively.
+</Note>
+
+#### `PostToolUse` Decision Control
+
+`PostToolUse` hooks can provide feedback to Claude after tool execution.
+
+* `"block"` automatically prompts Claude with `reason`.
+* `undefined` does nothing. `reason` is ignored.
+* `"hookSpecificOutput.additionalContext"` adds context for Claude to consider.
+
+```json  theme={null}
+{
+  "decision": "block" | undefined,
+  "reason": "Explanation for decision",
+  "hookSpecificOutput": {
+    "hookEventName": "PostToolUse",
+    "additionalContext": "Additional information for Claude"
+  }
+}
+```
+
+#### `UserPromptSubmit` Decision Control
+
+`UserPromptSubmit` hooks can control whether a user prompt is processed.
+
+* `"block"` prevents the prompt from being processed. The submitted prompt is
+  erased from context. `"reason"` is shown to the user but not added to context.
+* `undefined` allows the prompt to proceed normally. `"reason"` is ignored.
+* `"hookSpecificOutput.additionalContext"` adds the string to the context if not
+  blocked.
+
+```json  theme={null}
+{
+  "decision": "block" | undefined,
+  "reason": "Explanation for decision",
+  "hookSpecificOutput": {
+    "hookEventName": "UserPromptSubmit",
+    "additionalContext": "My additional context here"
+  }
+}
+```
+
+#### `Stop`/`SubagentStop` Decision Control
+
+`Stop` and `SubagentStop` hooks can control whether Claude must continue.
+
+* `"block"` prevents Claude from stopping. You must populate `reason` for Claude
+  to know how to proceed.
+* `undefined` allows Claude to stop. `reason` is ignored.
+
+```json  theme={null}
+{
+  "decision": "block" | undefined,
+  "reason": "Must be provided when Claude is blocked from stopping"
+}
+```
+
+#### `SessionStart` Decision Control
+
+`SessionStart` hooks allow you to load in context at the start of a session.
+
+* `"hookSpecificOutput.additionalContext"` adds the string to the context.
+* Multiple hooks' `additionalContext` values are concatenated.
+
+```json  theme={null}
+{
+  "hookSpecificOutput": {
+    "hookEventName": "SessionStart",
+    "additionalContext": "My additional context here"
+  }
+}
+```
+
+#### `SessionEnd` Decision Control
+
+`SessionEnd` hooks run when a session ends. They cannot block session termination
+but can perform cleanup tasks.
+
+#### Exit Code Example: Bash Command Validation
+
+```python  theme={null}
+#!/usr/bin/env python3
+import json
+import re
+import sys
+
+# Define validation rules as a list of (regex pattern, message) tuples
+VALIDATION_RULES = [
+    (
+        r"\bgrep\b(?!.*\|)",
+        "Use 'rg' (ripgrep) instead of 'grep' for better performance and features",
+    ),
+    (
+        r"\bfind\s+\S+\s+-name\b",
+        "Use 'rg --files | rg pattern' or 'rg --files -g pattern' instead of 'find -name' for better performance",
+    ),
+]
+
+
+def validate_command(command: str) -> list[str]:
+    issues = []
+    for pattern, message in VALIDATION_RULES:
+        if re.search(pattern, command):
+            issues.append(message)
+    return issues
+
+
+try:
+    input_data = json.load(sys.stdin)
+except json.JSONDecodeError as e:
+    print(f"Error: Invalid JSON input: {e}", file=sys.stderr)
+    sys.exit(1)
+
+tool_name = input_data.get("tool_name", "")
+tool_input = input_data.get("tool_input", {})
+command = tool_input.get("command", "")
+
+if tool_name != "Bash" or not command:
+    sys.exit(1)
+
+# Validate the command
+issues = validate_command(command)
+
+if issues:
+    for message in issues:
+        print(f"• {message}", file=sys.stderr)
+    # Exit code 2 blocks tool call and shows stderr to Claude
+    sys.exit(2)
+```
+
+#### JSON Output Example: UserPromptSubmit to Add Context and Validation
+
+<Note>
+  For `UserPromptSubmit` hooks, you can inject context using either method:
+
+  * Exit code 0 with stdout: Claude sees the context (special case for `UserPromptSubmit`)
+  * JSON output: Provides more control over the behavior
+</Note>
+
+```python  theme={null}
+#!/usr/bin/env python3
+import json
+import sys
+import re
+import datetime
+
+# Load input from stdin
+try:
+    input_data = json.load(sys.stdin)
+except json.JSONDecodeError as e:
+    print(f"Error: Invalid JSON input: {e}", file=sys.stderr)
+    sys.exit(1)
+
+prompt = input_data.get("prompt", "")
+
+# Check for sensitive patterns
+sensitive_patterns = [
+    (r"(?i)\b(password|secret|key|token)\s*[:=]", "Prompt contains potential secrets"),
+]
+
+for pattern, message in sensitive_patterns:
+    if re.search(pattern, prompt):
+        # Use JSON output to block with a specific reason
+        output = {
+            "decision": "block",
+            "reason": f"Security policy violation: {message}. Please rephrase your request without sensitive information."
+        }
+        print(json.dumps(output))
+        sys.exit(0)
+
+# Add current time to context
+context = f"Current time: {datetime.datetime.now()}"
+print(context)
+
+"""
+The following is also equivalent:

+    "additionalContext": context,
+  },
+}))
+"""
+
+# Allow the prompt to proceed with the additional context
+sys.exit(0)
+```
+
+#### JSON Output Example: PreToolUse with Approval
+
+```python  theme={null}
+#!/usr/bin/env python3
+import json
+import sys
+
+# Load input from stdin
+try:
+    input_data = json.load(sys.stdin)
+except json.JSONDecodeError as e:
+    print(f"Error: Invalid JSON input: {e}", file=sys.stderr)
+    sys.exit(1)
+
+tool_name = input_data.get("tool_name", "")
+tool_input = input_data.get("tool_input", {})
+
+# Example: Auto-approve file reads for documentation files
+if tool_name == "Read":
+    file_path = tool_input.get("file_path", "")
+    if file_path.endswith((".md", ".mdx", ".txt", ".json")):
+        # Use JSON output to auto-approve the tool call
+        output = {
+            "decision": "approve",
+            "reason": "Documentation file auto-approved",
+            "suppressOutput": True  # Don't show in transcript mode
+        }
+        print(json.dumps(output))
+        sys.exit(0)
+
+# For other cases, let the normal permission flow proceed
+sys.exit(0)
+```
+
+## Working with MCP Tools
+
+Claude Code hooks work seamlessly with
+[Model Context Protocol (MCP) tools](/en/docs/claude-code/mcp). When MCP servers
+provide tools, they appear with a special naming pattern that you can match in
+your hooks.
+
+### MCP Tool Naming
+
+MCP tools follow the pattern `mcp__<server>__<tool>`, for example:
+
+* `mcp__memory__create_entities` - Memory server's create entities tool
+* `mcp__filesystem__read_file` - Filesystem server's read file tool
+* `mcp__github__search_repositories` - GitHub server's search tool
+
+### Configuring Hooks for MCP Tools
+
+You can target specific MCP tools or entire MCP servers:
+
+```json  theme={null}
+{
+  "hooks": {
+    "PreToolUse": [
+      {
+        "matcher": "mcp__memory__.*",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "echo 'Memory operation initiated' >> ~/mcp-operations.log"
+          }
+        ]
+      },
+      {
+        "matcher": "mcp__.*__write.*",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "/home/user/scripts/validate-mcp-write.py"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+## Examples
+
+<Tip>
+  For practical examples including code formatting, notifications, and file protection, see [More Examples](/en/docs/claude-code/hooks-guide#more-examples) in the get started guide.
+</Tip>
+
+## Security Considerations
+
+### Disclaimer
+
+**USE AT YOUR OWN RISK**: Claude Code hooks execute arbitrary shell commands on
+your system automatically. By using hooks, you acknowledge that:
+
+* You are solely responsible for the commands you configure
+* Hooks can modify, delete, or access any files your user account can access
+* Malicious or poorly written hooks can cause data loss or system damage
+* Anthropic provides no warranty and assumes no liability for any damages
+  resulting from hook usage
+* You should thoroughly test hooks in a safe environment before production use
+
+Always review and understand any hook commands before adding them to your
+configuration.
+
+### Security Best Practices
+
+Here are some key practices for writing more secure hooks:
+
+1. **Validate and sanitize inputs** - Never trust input data blindly
+2. **Always quote shell variables** - Use `"$VAR"` not `$VAR`
+3. **Block path traversal** - Check for `..` in file paths
+4. **Use absolute paths** - Specify full paths for scripts (use
+   "\$CLAUDE\_PROJECT\_DIR" for the project path)
+5. **Skip sensitive files** - Avoid `.env`, `.git/`, keys, etc.
+
+### Configuration Safety
+
+Direct edits to hooks in settings files don't take effect immediately. Claude
+Code:
+
+1. Captures a snapshot of hooks at startup
+2. Uses this snapshot throughout the session
+3. Warns if hooks are modified externally
+4. Requires review in `/hooks` menu for changes to apply
+
+This prevents malicious hook modifications from affecting your current session.
+
+## Hook Execution Details
+
+* **Timeout**: 60-second execution limit by default, configurable per command.
+  * A timeout for an individual command does not affect the other commands.
+* **Parallelization**: All matching hooks run in parallel
+* **Deduplication**: Multiple identical hook commands are deduplicated automatically
+* **Environment**: Runs in current directory with Claude Code's environment
+  * The `CLAUDE_PROJECT_DIR` environment variable is available and contains the
+    absolute path to the project root directory (where Claude Code was started)
+* **Input**: JSON via stdin
+* **Output**:
+  * PreToolUse/PostToolUse/Stop/SubagentStop: Progress shown in transcript (Ctrl-R)
+  * Notification/SessionEnd: Logged to debug only (`--debug`)
+  * UserPromptSubmit/SessionStart: stdout added as context for Claude
+
+## Debugging
+
+### Basic Troubleshooting
+
+If your hooks aren't working:
+
+1. **Check configuration** - Run `/hooks` to see if your hook is registered
+2. **Verify syntax** - Ensure your JSON settings are valid
+3. **Test commands** - Run hook commands manually first
+4. **Check permissions** - Make sure scripts are executable
+5. **Review logs** - Use `claude --debug` to see hook execution details
+
+Common issues:
+
+* **Quotes not escaped** - Use `\"` inside JSON strings
+* **Wrong matcher** - Check tool names match exactly (case-sensitive)
+* **Command not found** - Use full paths for scripts
+
+### Advanced Debugging
+
+For complex hook issues:
+
+1. **Inspect hook execution** - Use `claude --debug` to see detailed hook
+   execution
+2. **Validate JSON schemas** - Test hook input/output with external tools
+3. **Check environment variables** - Verify Claude Code's environment is correct
+4. **Test edge cases** - Try hooks with unusual file paths or inputs
+5. **Monitor system resources** - Check for resource exhaustion during hook
+   execution
+6. **Use structured logging** - Implement logging in your hook scripts
+
+### Debug Output Example
+
+Use `claude --debug` to see hook execution details:
+
+```
+[DEBUG] Executing hooks for PostToolUse:Write
+[DEBUG] Getting matching hook commands for PostToolUse with query: Write
+[DEBUG] Found 1 hook matchers in settings
+[DEBUG] Matched 1 hooks for query "Write"
+[DEBUG] Found 1 hook commands to execute
+[DEBUG] Executing hook command: <Your command> with timeout 60000ms
+[DEBUG] Hook command completed with status 0: <Your stdout>
+```
+
+Progress messages appear in transcript mode (Ctrl-R) showing:
+
+* Which hook is running
+* Command being executed
+* Success/failure status
+* Output or error messages

+# Plugins
+
+> Extend Claude Code with custom commands, agents, hooks, and MCP servers through the plugin system.
+
+<Tip>
+  For complete technical specifications and schemas, see [Plugins reference](/en/docs/claude-code/plugins-reference). For marketplace management, see [Plugin marketplaces](/en/docs/claude-code/plugin-marketplaces).
+</Tip>
+
+Plugins let you extend Claude Code with custom functionality that can be shared across projects and teams. Install plugins from [marketplaces](/en/docs/claude-code/plugin-marketplaces) to add pre-built commands, agents, hooks, and MCP servers, or create your own to automate your workflows.
+
+## Quickstart
+
+Let's create a simple greeting plugin to get you familiar with the plugin system. We'll build a working plugin that adds a custom command, test it locally, and understand the core concepts.
+
+### Prerequisites
+
+* Claude Code installed on your machine
+* Basic familiarity with command-line tools
+
+### Create your first plugin
+
+<Steps>
+  <Step title="Create the marketplace structure">
+    ```bash  theme={null}
+    mkdir test-marketplace
+    cd test-marketplace
+    ```
+  </Step>
+
+  <Step title="Create the plugin directory">
+    ```bash  theme={null}
+    mkdir my-first-plugin
+    cd my-first-plugin
+    ```
+  </Step>
+
+  <Step title="Create the plugin manifest">
+    ```bash Create .claude-plugin/plugin.json theme={null}
+    mkdir .claude-plugin
+    cat > .claude-plugin/plugin.json << 'EOF'
+    {
+    "name": "my-first-plugin",
+    "description": "A simple greeting plugin to learn the basics",
+    "version": "1.0.0",
+    "author": {
+    "name": "Your Name"
+    }
+    }
+    EOF
+    ```
+  </Step>
+
+  <Step title="Add a custom command">
+    ```bash Create commands/hello.md theme={null}
+    mkdir commands
+    cat > commands/hello.md << 'EOF'
+    ---
+    description: Greet the user with a personalized message
+    ---
+
+    # Hello Command
+
+    Greet the user warmly and ask how you can help them today. Make the greeting personal and encouraging.
+    EOF
+    ```
+  </Step>
+
+  <Step title="Create the marketplace manifest">
+    ```bash Create marketplace.json theme={null}
+    cd ..
+    mkdir .claude-plugin
+    cat > .claude-plugin/marketplace.json << 'EOF'
+    {
+    "name": "test-marketplace",
+    "owner": {
+    "name": "Test User"
+    },
+    "plugins": [
+    {
+      "name": "my-first-plugin",
+      "source": "./my-first-plugin",
+      "description": "My first test plugin"
+    }
+    ]
+    }
+    EOF
+    ```
+  </Step>
+
+  <Step title="Install and test your plugin">
+    ```bash Start Claude Code from parent directory theme={null}
+    cd ..
+    claude
+    ```
+
+    ```shell Add the test marketplace theme={null}
+    /plugin marketplace add ./test-marketplace
+    ```
+
+    ```shell Install your plugin theme={null}
+    /plugin install my-first-plugin@test-marketplace
+    ```
+
+    Select "Install now". You'll then need to restart Claude Code in order to use the new plugin.
+
+    ```shell Try your new command theme={null}
+    /hello
+    ```
+
+    You'll see Claude use your greeting command! Check `/help` to see your new command listed.
+  </Step>
+</Steps>
+
+You've successfully created and tested a plugin with these key components:
+
+* **Plugin manifest** (`.claude-plugin/plugin.json`) - Describes your plugin's metadata
+* **Commands directory** (`commands/`) - Contains your custom slash commands
+* **Test marketplace** - Allows you to test your plugin locally
+
+### Plugin structure overview
+
+Your plugin follows this basic structure:
+
+```
+my-first-plugin/
+├── .claude-plugin/
+│   └── plugin.json          # Plugin metadata
+├── commands/                 # Custom slash commands (optional)
+│   └── hello.md
+├── agents/                   # Custom agents (optional)
+│   └── helper.md
+├── skills/                   # Agent Skills (optional)
+│   └── my-skill/
+│       └── SKILL.md
+└── hooks/                    # Event handlers (optional)
+    └── hooks.json
+```
+
+**Additional components you can add:**
+
+* **Commands**: Create markdown files in `commands/` directory
+* **Agents**: Create agent definitions in `agents/` directory
+* **Skills**: Create `SKILL.md` files in `skills/` directory
+* **Hooks**: Create `hooks/hooks.json` for event handling
+* **MCP servers**: Create `.mcp.json` for external tool integration
+
+<Note>
+  **Next steps**: Ready to add more features? Jump to [Develop more complex plugins](#develop-more-complex-plugins) to add agents, hooks, and MCP servers. For complete technical specifications of all plugin components, see [Plugins reference](/en/docs/claude-code/plugins-reference).

+
+## Install and manage plugins
+
+Learn how to discover, install, and manage plugins to extend your Claude Code capabilities.
+
+### Prerequisites
+
+* Claude Code installed and running
+* Basic familiarity with command-line interfaces
+
+### Add marketplaces
+
+Marketplaces are catalogs of available plugins. Add them to discover and install plugins:
+
+```shell Add a marketplace theme={null}
+/plugin marketplace add your-org/claude-plugins
+```
+
+```shell Browse available plugins theme={null}
+/plugin
+```
+
+For detailed marketplace management including Git repositories, local development, and team distribution, see [Plugin marketplaces](/en/docs/claude-code/plugin-marketplaces).
+
+### Install plugins
+
+#### Via interactive menu (recommended for discovery)
+
+```shell Open the plugin management interface theme={null}
+/plugin
+```
+
+Select "Browse Plugins" to see available options with descriptions, features, and installation options.
+
+#### Via direct commands (for quick installation)
+
+```shell Install a specific plugin theme={null}
+/plugin install formatter@your-org
+```
+
+```shell Enable a disabled plugin theme={null}
+/plugin enable plugin-name@marketplace-name
+```
+
+```shell Disable without uninstalling theme={null}
+/plugin disable plugin-name@marketplace-name
+```
+
+```shell Completely remove a plugin theme={null}
+/plugin uninstall plugin-name@marketplace-name
+```
+
+### Verify installation
+
+After installing a plugin:
+
+1. **Check available commands**: Run `/help` to see new commands
+2. **Test plugin features**: Try the plugin's commands and features
+3. **Review plugin details**: Use `/plugin` → "Manage Plugins" to see what the plugin provides
+
+## Set up team plugin workflows
+
+Configure plugins at the repository level to ensure consistent tooling across your team. When team members trust your repository folder, Claude Code automatically installs specified marketplaces and plugins.
+
+**To set up team plugins:**
+
+1. Add marketplace and plugin configuration to your repository's `.claude/settings.json`
+2. Team members trust the repository folder
+3. Plugins install automatically for all team members
+
+For complete instructions including configuration examples, marketplace setup, and rollout best practices, see [Configure team marketplaces](/en/docs/claude-code/plugin-marketplaces#how-to-configure-team-marketplaces).
+
+***
+
+## Develop more complex plugins
+
+Once you're comfortable with basic plugins, you can create more sophisticated extensions.
+
+### Add Skills to your plugin
+
+Plugins can include [Agent Skills](/en/docs/claude-code/skills) to extend Claude's capabilities. Skills are model-invoked—Claude autonomously uses them based on the task context.
+
+To add Skills to your plugin, create a `skills/` directory at your plugin root and add Skill folders with `SKILL.md` files. Plugin Skills are automatically available when the plugin is installed.
+
+For complete Skill authoring guidance, see [Agent Skills](/en/docs/claude-code/skills).
+
+### Organize complex plugins
+
+For plugins with many components, organize your directory structure by functionality. For complete directory layouts and organization patterns, see [Plugin directory structure](/en/docs/claude-code/plugins-reference#plugin-directory-structure).
+
+### Test your plugins locally
+
+When developing plugins, use a local marketplace to test changes iteratively. This workflow builds on the quickstart pattern and works for plugins of any complexity.
+
+<Steps>
+  <Step title="Set up your development structure">
+    Organize your plugin and marketplace for testing:
+
+    ```bash Create directory structure theme={null}
+    mkdir dev-marketplace
+    cd dev-marketplace
+    mkdir my-plugin
+    ```
+
+    This creates:
+
+    ```
+    dev-marketplace/
+    ├── .claude-plugin/marketplace.json  (you'll create this)
+    └── my-plugin/                        (your plugin under development)
+        ├── .claude-plugin/plugin.json
+        ├── commands/
+        ├── agents/
+        └── hooks/
+    ```
+  </Step>
+
+  <Step title="Create the marketplace manifest">
+    ```bash Create marketplace.json theme={null}
+    mkdir .claude-plugin
+    cat > .claude-plugin/marketplace.json << 'EOF'
+    {
+    "name": "dev-marketplace",
+    "owner": {
+    "name": "Developer"
+    },
+    "plugins": [
+    {
+      "name": "my-plugin",
+      "source": "./my-plugin",
+      "description": "Plugin under development"
+    }
+    ]
+    }
+    EOF
+    ```
+  </Step>
+
+  <Step title="Install and test">
+    ```bash Start Claude Code from parent directory theme={null}
+    cd ..
+    claude
+    ```
+
+    ```shell Add your development marketplace theme={null}
+    /plugin marketplace add ./dev-marketplace
+    ```
+
+    ```shell Install your plugin theme={null}
+    /plugin install my-plugin@dev-marketplace
+    ```
+
+    Test your plugin components:
+
+    * Try your commands with `/command-name`
+    * Check that agents appear in `/agents`
+    * Verify hooks work as expected
+  </Step>
+
+  <Step title="Iterate on your plugin">
+    After making changes to your plugin code:
+
+    ```shell Uninstall the current version theme={null}
+    /plugin uninstall my-plugin@dev-marketplace
+    ```
+
+    ```shell Reinstall to test changes theme={null}
+    /plugin install my-plugin@dev-marketplace
+    ```
+
+    Repeat this cycle as you develop and refine your plugin.
+  </Step>
+</Steps>
+
+<Note>
+  **For multiple plugins**: Organize plugins in subdirectories like `./plugins/plugin-name` and update your marketplace.json accordingly. See [Plugin sources](/en/docs/claude-code/plugin-marketplaces#plugin-sources) for organization patterns.
+</Note>
+
+### Debug plugin issues
+
+If your plugin isn't working as expected:
+
+1. **Check the structure**: Ensure your directories are at the plugin root, not inside `.claude-plugin/`
+2. **Test components individually**: Check each command, agent, and hook separately
+3. **Use validation and debugging tools**: See [Debugging and development tools](/en/docs/claude-code/plugins-reference#debugging-and-development-tools) for CLI commands and troubleshooting techniques
+
+### Share your plugins
+
+When your plugin is ready to share:
+
+1. **Add documentation**: Include a README.md with installation and usage instructions
+2. **Version your plugin**: Use semantic versioning in your `plugin.json`
+3. **Create or use a marketplace**: Distribute through plugin marketplaces for easy installation
+4. **Test with others**: Have team members test the plugin before wider distribution
+
+<Note>
+  For complete technical specifications, debugging techniques, and distribution strategies, see [Plugins reference](/en/docs/claude-code/plugins-reference).
+</Note>
+

+<Note>Models with the same snapshot date (e.g., 20240620) are identical across all platforms and do not change. The snapshot date in the model name ensures consistency and allows developers to rely on stable performance across different environments.</Note>
+
+<Note>Starting with **Claude Sonnet 4.5 and all future models**, AWS Bedrock and Google Vertex AI offer two endpoint types: **global endpoints** (dynamic routing for maximum availability) and **regional endpoints** (guaranteed data routing through specific geographic regions). For more information, see the [third-party platform pricing section](/en/docs/about-claude/pricing#third-party-platform-pricing).</Note>
+
+### Model aliases
+
+For convenience during development and testing, we offer aliases for our model ids. These aliases automatically point to the most recent snapshot of a given model. When we release new model snapshots, we migrate aliases to point to the newest version of a model, typically within a week of the new release.
+
+<Tip>
+  While aliases are useful for experimentation, we recommend using specific model versions (e.g., `claude-sonnet-4-5-20250929`) in production applications to ensure consistent behavior.

+*<sup>1 - Claude Sonnet 4.5 and Claude Sonnet 4 support a [1M token context window](/en/docs/build-with-claude/context-windows#1m-token-context-window) when using the `context-1m-2025-08-07` beta header. [Long context pricing](/en/docs/about-claude/pricing#long-context-pricing) applies to requests exceeding 200K tokens.</sup>*
+
+*<sup>2 - **Reliable knowledge cutoff** indicates the date through which a model's knowledge is most extensive and reliable. **Training data cutoff** is the broader date range of training data used. For example, Claude Sonnet 4.5 was trained on publicly available information through July 2025, but its knowledge is most extensive and reliable through January 2025. For more information, see [Anthropic's Transparency Hub](https://www.anthropic.com/transparency).</sup>*
+
+*<sup>3 - Some Haiku models have a single training data cutoff date.</sup>*
+
+<Note>
+  Include the beta header `output-128k-2025-02-19` in your API request to increase the maximum output token length to 128k tokens for Claude Sonnet 3.7.
+
+  We strongly suggest using our [streaming Messages API](/en/docs/build-with-claude/streaming) to avoid timeouts when generating longer outputs.
+  See our guidance on [long requests](/en/api/errors#long-requests) for more details.

+## Prompt and output performance
+
+Claude 4 models excel in:
+
+* **Performance**: Top-tier results in reasoning, coding, multilingual tasks, long-context handling, honesty, and image processing. See the [Claude 4 blog post](http://www.anthropic.com/news/claude-4) for more information.
+* **Engaging responses**: Claude models are ideal for applications that require rich, human-like interactions.
+
+  * If you prefer more concise responses, you can adjust your prompts to guide the model toward the desired output length. Refer to our [prompt engineering guides](/en/docs/build-with-claude/prompt-engineering) for details.
+  * For specific Claude 4 prompting best practices, see our [Claude 4 best practices guide](/en/docs/build-with-claude/prompt-engineering/claude-4-best-practices).
+* **Output quality**: When migrating from previous model generations to Claude 4, you may notice larger improvements in overall performance.
+
+## Migrating to Claude 4.5
+
+If you're currently using Claude 3 models, we recommend migrating to Claude 4.5 to take advantage of improved intelligence and enhanced capabilities. For detailed migration instructions, see [Migrating to Claude 4.5](/en/docs/about-claude/models/migrating-to-claude-4).

+# Plugins reference
+
+> Complete technical reference for Claude Code plugin system, including schemas, CLI commands, and component specifications.
+
+<Tip>
+  For hands-on tutorials and practical usage, see [Plugins](/en/docs/claude-code/plugins). For plugin management across teams and communities, see [Plugin marketplaces](/en/docs/claude-code/plugin-marketplaces).
+</Tip>
+
+This reference provides complete technical specifications for the Claude Code plugin system, including component schemas, CLI commands, and development tools.
+
+## Plugin components reference
+
+This section documents the five types of components that plugins can provide.
+
+### Commands
+
+Plugins add custom slash commands that integrate seamlessly with Claude Code's command system.
+
+**Location**: `commands/` directory in plugin root
+
+**File format**: Markdown files with frontmatter
+
+For complete details on plugin command structure, invocation patterns, and features, see [Plugin commands](/en/docs/claude-code/slash-commands#plugin-commands).
+
+### Agents
+
+Plugins can provide specialized subagents for specific tasks that Claude can invoke automatically when appropriate.
+
+**Location**: `agents/` directory in plugin root
+
+**File format**: Markdown files describing agent capabilities
+
+**Agent structure**:
+
+```markdown  theme={null}
+---
+description: What this agent specializes in
+capabilities: ["task1", "task2", "task3"]
+---
+
+# Agent Name
+
+Detailed description of the agent's role, expertise, and when Claude should invoke it.
+
+## Capabilities
+- Specific task the agent excels at
+- Another specialized capability
+- When to use this agent vs others
+
+## Context and examples
+Provide examples of when this agent should be used and what kinds of problems it solves.
+```
+
+**Integration points**:
+
+* Agents appear in the `/agents` interface
+* Claude can invoke agents automatically based on task context
+* Agents can be invoked manually by users
+* Plugin agents work alongside built-in Claude agents
+
+### Skills
+
+Plugins can provide Agent Skills that extend Claude's capabilities. Skills are model-invoked—Claude autonomously decides when to use them based on the task context.
+
+**Location**: `skills/` directory in plugin root
+
+**File format**: Directories containing `SKILL.md` files with frontmatter
+
+**Skill structure**:
+
+```
+skills/
+├── pdf-processor/
+│   ├── SKILL.md
+│   ├── reference.md (optional)
+│   └── scripts/ (optional)
+└── code-reviewer/
+    └── SKILL.md
+```
+
+**Integration behavior**:
+
+* Plugin Skills are automatically discovered when the plugin is installed
+* Claude autonomously invokes Skills based on matching task context
+* Skills can include supporting files alongside SKILL.md
+
+For SKILL.md format and complete Skill authoring guidance, see:
+
+* [Use Skills in Claude Code](/en/docs/claude-code/skills)
+* [Agent Skills overview](/en/docs/agents-and-tools/agent-skills/overview#skill-structure)
+
+### Hooks
+
+Plugins can provide event handlers that respond to Claude Code events automatically.
+
+**Location**: `hooks/hooks.json` in plugin root, or inline in plugin.json
+
+**Format**: JSON configuration with event matchers and actions
+
+**Hook configuration**:
+
+```json  theme={null}
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "matcher": "Write|Edit",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "${CLAUDE_PLUGIN_ROOT}/scripts/format-code.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+**Available events**:
+
+* `PreToolUse`: Before Claude uses any tool
+* `PostToolUse`: After Claude uses any tool
+* `UserPromptSubmit`: When user submits a prompt
+* `Notification`: When Claude Code sends notifications
+* `Stop`: When Claude attempts to stop
+* `SubagentStop`: When a subagent attempts to stop
+* `SessionStart`: At the beginning of sessions
+* `SessionEnd`: At the end of sessions
+* `PreCompact`: Before conversation history is compacted
+
+**Hook types**:
+
+* `command`: Execute shell commands or scripts
+* `validation`: Validate file contents or project state
+* `notification`: Send alerts or status updates
+
+### MCP servers
+
+Plugins can bundle Model Context Protocol (MCP) servers to connect Claude Code with external tools and services.
+
+**Location**: `.mcp.json` in plugin root, or inline in plugin.json
+
+**Format**: Standard MCP server configuration
+
+**MCP server configuration**:
+
+```json  theme={null}
+{
+  "mcpServers": {
+    "plugin-database": {
+      "command": "${CLAUDE_PLUGIN_ROOT}/servers/db-server",
+      "args": ["--config", "${CLAUDE_PLUGIN_ROOT}/config.json"],
+      "env": {
+        "DB_PATH": "${CLAUDE_PLUGIN_ROOT}/data"
+      }
+    },
+    "plugin-api-client": {
+      "command": "npx",
+      "args": ["@company/mcp-server", "--plugin-mode"],
+      "cwd": "${CLAUDE_PLUGIN_ROOT}"
+    }
+  }
+}
+```
+
+**Integration behavior**:
+
+* Plugin MCP servers start automatically when the plugin is enabled
+* Servers appear as standard MCP tools in Claude's toolkit
+* Server capabilities integrate seamlessly with Claude's existing tools
+* Plugin servers can be configured independently of user MCP servers
+
+***
+
+## Plugin manifest schema
+
+The `plugin.json` file defines your plugin's metadata and configuration. This section documents all supported fields and options.

+
+### Component path fields
+
+| Field        | Type           | Description                          | Example                                |

+| `mcpServers` | string\|object | MCP config path or inline config     | `"./mcp.json"`                         |
+
+### Path behavior rules
+
+**Important**: Custom paths supplement default directories - they don't replace them.
+
+* If `commands/` exists, it's loaded in addition to custom command paths
+* All paths must be relative to plugin root and start with `./`
+* Commands from custom paths use the same naming and namespacing rules
+* Multiple paths can be specified as arrays for flexibility
+
+**Path examples**:
+
+```json  theme={null}
+{
+  "commands": [
+    "./specialized/deploy.md",
+    "./utilities/batch-process.md"
+  ],
+  "agents": [
+    "./custom-agents/reviewer.md",
+    "./custom-agents/tester.md"
+  ]
+}
+```
+
+### Environment variables
+
+**`${CLAUDE_PLUGIN_ROOT}`**: Contains the absolute path to your plugin directory. Use this in hooks, MCP servers, and scripts to ensure correct paths regardless of installation location.
+
+```json  theme={null}
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "hooks": [
+          {
+            "type": "command",
+            "command": "${CLAUDE_PLUGIN_ROOT}/scripts/process.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+

+# Streaming Input
+
+> Understanding the two input modes for Claude Agent SDK and when to use each
+
+## Overview
+
+The Claude Agent SDK supports two distinct input modes for interacting with agents:
+
+* **Streaming Input Mode** (Default & Recommended) - A persistent, interactive session
+* **Single Message Input** - One-shot queries that use session state and resuming
+
+This guide explains the differences, benefits, and use cases for each mode to help you choose the right approach for your application.
+
+## Streaming Input Mode (Recommended)
+
+Streaming input mode is the **preferred** way to use the Claude Agent SDK. It provides full access to the agent's capabilities and enables rich, interactive experiences.
+
+It allows the agent to operate as a long lived process that takes in user input, handles interruptions, surfaces permission requests, and handles session management.
+
+### How It Works
+

+%%{init: {"theme": "base", "themeVariables": {"edgeLabelBackground": "#F0F0EB", "lineColor": "#91918D", "primaryColor": "#F0F0EB", "primaryTextColor": "#191919", "primaryBorderColor": "#D9D8D5", "secondaryColor": "#F5E6D8", "tertiaryColor": "#CC785C", "noteBkgColor": "#FAF0E6", "noteBorderColor": "#91918D"}, "sequence": {"actorMargin": 50, "width": 150, "height": 65, "boxMargin": 10, "boxTextMargin": 5, "noteMargin": 10, "messageMargin": 35}}}%%

+
+          # Process responses
+          async for message in client.receive_response():
+              if isinstance(message, AssistantMessage):
+                  for block in message.content:
+                      if isinstance(block, TextBlock):
+                          print(block.text)
+
+  asyncio.run(streaming_analysis())
+  ```
+</CodeGroup>
+
+## Single Message Input
+
+Single message input is simpler but more limited.
+
+### When to Use Single Message Input
+
+Use single message input when:
+
+* You need a one-shot response
+* You do not need image attachments, hooks, etc.
+* You need to operate in a stateless environment, such as a lambda function
+
+### Limitations
+
+<Warning>
+  Single message input mode does **not** support:
+
+  * Direct image attachments in messages
+  * Dynamic message queueing
+  * Real-time interruption
+  * Hook integration
+  * Natural multi-turn conversations
+</Warning>
+
+### Implementation Example
+
+<CodeGroup>
+  ```typescript TypeScript theme={null}
+  import { query } from "@anthropic-ai/claude-agent-sdk";
+
+  // Simple one-shot query
+  for await (const message of query({
+    prompt: "Explain the authentication flow",
+    options: {
+      maxTurns: 1,
+      allowedTools: ["Read", "Grep"]
+    }
+  })) {
+    if (message.type === "result") {
+      console.log(message.result);
+    }
+  }
+
+  // Continue conversation with session management
+  for await (const message of query({
+    prompt: "Now explain the authorization process",
+    options: {
+      continue: true,
+      maxTurns: 1
+    }
+  })) {
+    if (message.type === "result") {
+      console.log(message.result);
+    }
+  }
+  ```
+
+  ```python Python theme={null}
+  from claude_agent_sdk import query, ClaudeAgentOptions, ResultMessage
+  import asyncio
+
+  async def single_message_example():
+      # Simple one-shot query using query() function
+      async for message in query(
+          prompt="Explain the authentication flow",
+          options=ClaudeAgentOptions(
+              max_turns=1,

+# Context Engineering for AI Agents: Best Practices Cheat Sheet
+
+## Core Principle
+**Find the smallest possible set of high-signal tokens that maximize the likelihood of your desired outcome.**
+
+---
+
+## Context Engineering vs Prompt Engineering
+
+**Prompt Engineering**: Writing and organizing LLM instructions for optimal outcomes (one-time task)
+
+**Context Engineering**: Curating and maintaining the optimal set of tokens during inference across multiple turns (iterative process)
+
+Context engineering manages:
+- System instructions
+- Tools
+- Model Context Protocol (MCP)
+- External data
+- Message history
+- Runtime data retrieval
+
+---
+
+## The Problem: Context Rot
+
+**Key Insight**: LLMs have an "attention budget" that gets depleted as context grows
+
+- Every token attends to every other token (n² relationships)
+- As context length increases, model accuracy decreases
+- Models have less training experience with longer sequences
+- Context must be treated as a finite resource with diminishing marginal returns
+
+---
+
+## System Prompts: Find the "Right Altitude"
+
+### The Goldilocks Zone
+
+**Too Prescriptive** ❌
+- Hardcoded if-else logic
+- Brittle and fragile
+- High maintenance complexity
+
+**Too Vague** ❌
+- High-level guidance without concrete signals
+- Falsely assumes shared context
+- Lacks actionable direction
+
+**Just Right** ✅
+- Specific enough to guide behavior effectively
+- Flexible enough to provide strong heuristics
+- Minimal set of information that fully outlines expected behavior
+
+### Best Practices
+- Use simple, direct language
+- Organize into distinct sections (`<background_information>`, `<instructions>`, `## Tool guidance`, etc.)
+- Use XML tags or Markdown headers for structure
+- Start with minimal prompt, add based on failure modes
+- Note: Minimal ≠ short (provide sufficient information upfront)
+
+---
+
+## Tools: Minimal and Clear
+
+### Design Principles
+- **Self-contained**: Each tool has a single, clear purpose
+- **Robust to error**: Handle edge cases gracefully
+- **Extremely clear**: Intended use is unambiguous
+- **Token-efficient**: Returns relevant information without bloat
+- **Descriptive parameters**: Unambiguous input names (e.g., `user_id` not `user`)
+
+### Critical Rule
+**If a human engineer can't definitively say which tool to use in a given situation, an AI agent can't be expected to do better.**
+
+### Common Failure Modes to Avoid
+- Bloated tool sets covering too much functionality
+- Tools with overlapping purposes
+- Ambiguous decision points about which tool to use
+
+---
+
+## Examples: Diverse, Not Exhaustive
+
+**Do** ✅
+- Curate a set of diverse, canonical examples
+- Show expected behavior effectively
+- Think "pictures worth a thousand words"
+
+**Don't** ❌
+- Stuff in a laundry list of edge cases
+- Try to articulate every possible rule
+- Overwhelm with exhaustive scenarios
+
+---
+
+## Context Retrieval Strategies
+
+### Just-In-Time Context (Recommended for Agents)
+**Approach**: Maintain lightweight identifiers (file paths, queries, links) and dynamically load data at runtime
+
+**Benefits**:
+- Avoids context pollution
+- Enables progressive disclosure
+- Mirrors human cognition (we don't memorize everything)
+- Leverages metadata (file names, folder structure, timestamps)
+- Agents discover context incrementally
+
+**Trade-offs**:
+- Slower than pre-computed retrieval
+- Requires proper tool guidance to avoid dead-ends
+
+### Pre-Inference Retrieval (Traditional RAG)
+**Approach**: Use embedding-based retrieval to surface context before inference
+
+**When to Use**: Static content that won't change during interaction
+
+### Hybrid Strategy (Best of Both)
+**Approach**: Retrieve some data upfront, enable autonomous exploration as needed
+
+**Example**: Claude Code loads CLAUDE.md files upfront, uses glob/grep for just-in-time retrieval
+
+**Rule of Thumb**: "Do the simplest thing that works"
+
+---
+
+## Long-Horizon Tasks: Three Techniques
+
+### 1. Compaction
+**What**: Summarize conversation nearing context limit, reinitiate with summary
+
+**Implementation**:
+- Pass message history to model for compression
+- Preserve critical details (architectural decisions, bugs, implementation)
+- Discard redundant outputs
+- Continue with compressed context + recently accessed files
+
+**Tuning Process**:
+1. **First**: Maximize recall (capture all relevant information)
+2. **Then**: Improve precision (eliminate superfluous content)
+
+**Low-Hanging Fruit**: Clear old tool calls and results
+
+**Best For**: Tasks requiring extensive back-and-forth
+
+### 2. Structured Note-Taking (Agentic Memory)
+**What**: Agent writes notes persisted outside context window, retrieved later
+
+**Examples**:
+- To-do lists
+- NOTES.md files
+- Game state tracking (Pokémon example: tracking 1,234 steps of training)
+- Project progress logs
+
+**Benefits**:
+- Persistent memory with minimal overhead
+- Maintains critical context across tool calls
+- Enables multi-hour coherent strategies
+
+**Best For**: Iterative development with clear milestones
+
+### 3. Sub-Agent Architectures
+**What**: Specialized sub-agents handle focused tasks with clean context windows
+
+**How It Works**:
+- Main agent coordinates high-level plan
+- Sub-agents perform deep technical work
+- Sub-agents explore extensively (tens of thousands of tokens)
+- Return condensed summaries (1,000-2,000 tokens)
+
+**Benefits**:
+- Clear separation of concerns
+- Parallel exploration
+- Detailed context remains isolated
+
+**Best For**: Complex research and analysis tasks
+
+---
+
+## Quick Decision Framework
+
+| Scenario | Recommended Approach |
+|----------|---------------------|
+| Static content | Pre-inference retrieval or hybrid |
+| Dynamic exploration needed | Just-in-time context |
+| Extended back-and-forth | Compaction |
+| Iterative development | Structured note-taking |
+| Complex research | Sub-agent architectures |
+| Rapid model improvement | "Do the simplest thing that works" |
+
+---
+
+## Key Takeaways
+
+1. **Context is finite**: Treat it as a precious resource with an attention budget
+2. **Think holistically**: Consider the entire state available to the LLM
+3. **Stay minimal**: More context isn't always better
+4. **Be iterative**: Context curation happens each time you pass to the model
+5. **Design for autonomy**: As models improve, let them act intelligently
+6. **Start simple**: Test with minimal setup, add based on failure modes
+
+---
+
+## Anti-Patterns to Avoid
+
+- ❌ Cramming everything into prompts
+- ❌ Creating brittle if-else logic
+- ❌ Building bloated tool sets
+- ❌ Stuffing exhaustive edge cases as examples
+- ❌ Assuming larger context windows solve everything
+- ❌ Ignoring context pollution over long interactions
+
+---
+
+## Remember
+
+> "Even as models continue to improve, the challenge of maintaining coherence across extended interactions will remain central to building more effective agents."
+
+Context engineering will evolve, but the core principle stays the same: **optimize signal-to-noise ratio in your token budget**.

+# Phase 1 Implementation - Complete ✅
+
+Phase 1 of the REFACTOR-PLAN.md has been successfully implemented and tested.
+
+## What Was Implemented
+
+### 1. Database Schema (Migration 004)
+Created four new tables to support the SDK agent architecture:
+
+- **`sdk_sessions`** - Tracks SDK streaming sessions
+- **`observation_queue`** - Message queue for pending observations
+- **`observations`** - Stores extracted observations from SDK
+- **`session_summaries`** - Stores structured session summaries
+
+All tables include proper indexes for performance and foreign key constraints for data integrity.
+
+### 2. Shared Database Layer
+Created `HooksDatabase` class ([src/services/sqlite/HooksDatabase.ts](src/services/sqlite/HooksDatabase.ts)) that provides:
+
+- Simple, synchronous database operations for hooks
+- No complex logic - just basic CRUD operations
+- Optimized SQLite settings (WAL mode, foreign keys enabled)
+- Methods for all hook operations:
+  - `getRecentSummaries()` - Retrieve session context
+  - `createSDKSession()` - Initialize new session
+  - `queueObservation()` - Add observation to queue
+  - `storeObservation()` - Save SDK observations
+  - `storeSummary()` - Save session summaries
+  - And more...
+
+### 3. Hook Functions
+Implemented all four hook functions in [src/hooks/](src/hooks/):
+
+#### **context.ts** - SessionStart Hook
+- Shows user recent session context on startup
+- Formats summaries in markdown for Claude
+- Exits silently if no context or errors occur
+
+#### **save.ts** - PostToolUse Hook
+- Queues tool observations for SDK processing
+- Skips low-value tools (TodoWrite, ListMcpResourcesTool)
+- Non-blocking - returns immediately
+
+#### **new.ts** - UserPromptSubmit Hook
+- Initializes SDK session in database
+- Prepares for SDK worker spawn (TODO in Phase 2)
+- Non-blocking - returns immediately
+
+#### **summary.ts** - Stop Hook
+- Queues FINALIZE message for SDK
+- Signals SDK to generate session summary
+- Non-blocking - returns immediately
+
+### 4. CLI Integration
+Added four new commands to [src/bin/cli.ts](src/bin/cli.ts:227-274):
+
+```bash
+claude-mem context   # SessionStart hook
+claude-mem new       # UserPromptSubmit hook
+claude-mem save      # PostToolUse hook
+claude-mem summary   # Stop hook
+```
+
+All commands read JSON input from stdin and execute the corresponding hook function.
+
+### 5. Testing
+Created comprehensive test suite ([test-phase1.ts](test-phase1.ts)) that validates:
+
+- ✅ Database schema migration 004 applied correctly
+- ✅ All four tables exist
+- ✅ SDK session creation and retrieval
+- ✅ Observation queue operations
+- ✅ Observation and summary storage
+- ✅ Session status transitions
+
+**All tests pass! 🎉**
+
+## What's Left for Phase 2
+
+The foundation is complete. Next steps:
+
+1. **SDK Worker Process** - Implement the background agent that:
+   - Polls observation queue
+   - Sends observations to Claude SDK
+   - Parses XML responses (`<observation>` and `<summary>` blocks)
+   - Stores results in database
+
+2. **SDK Prompts** - Implement the three prompt builders:
+   - `buildInitPrompt()` - Initialize SDK agent
+   - `buildObservationPrompt()` - Send tool observation
+   - `buildFinalizePrompt()` - Request session summary
+
+3. **Process Management** - Update [src/hooks/new.ts](src/hooks/new.ts:35-42) to spawn SDK worker as detached process
+
+4. **End-to-End Testing** - Test with real Claude Code session
+
+## File Changes
+
+### New Files
+- [src/services/sqlite/HooksDatabase.ts](src/services/sqlite/HooksDatabase.ts) - Shared database layer
+- [src/hooks/context.ts](src/hooks/context.ts) - SessionStart hook
+- [src/hooks/save.ts](src/hooks/save.ts) - PostToolUse hook
+- [src/hooks/new.ts](src/hooks/new.ts) - UserPromptSubmit hook
+- [src/hooks/summary.ts](src/hooks/summary.ts) - Stop hook
+- [src/hooks/index.ts](src/hooks/index.ts) - Exports
+- [test-phase1.ts](test-phase1.ts) - Test suite
+
+### Modified Files
+- [src/services/sqlite/migrations.ts](src/services/sqlite/migrations.ts:205-315) - Added migration 004
+- [src/services/sqlite/index.ts](src/services/sqlite/index.ts:13) - Exported HooksDatabase
+- [src/bin/cli.ts](src/bin/cli.ts:227-274) - Added hook commands
+
+## Verification
+
+To verify Phase 1 implementation:
+
+```bash
+# Build
+bun run build
+
+# Run tests
+bun test-phase1.ts
+
+# Check hook commands exist
+./dist/claude-mem.min.js --help | grep -A 1 'context\|new\|save\|summary'
+```
+
+All should pass without errors.
+
+## Next Steps
+
+Ready to proceed to Phase 2: **SDK Worker Implementation**
+
+The architecture is sound, the database layer is working, and all hook functions are ready to integrate with the SDK worker process.

+📌 Version: 3.9.16
+✓ Bun detected
+✓ Cleaned dist directory
+✓ Bundle created
+✓ Shebang added
+✓ Made executable
+✅ Build complete! (344.57 KB)
+```
+
+## Success Criteria
+
+All Phase 2 success criteria have been met:
+
+- [x] SDK worker runs as detached process
+- [x] Worker polls observation queue continuously
+- [x] Worker sends observations to Claude SDK
+- [x] Worker parses `<observation>` and `<summary>` XML correctly
+- [x] Worker stores results in database using HooksDatabase
+- [x] Worker handles FINALIZE message and exits gracefully
+- [x] All tests pass
+- [x] No blocking of main Claude Code session
+
+## Known Limitations
+
+1. **Bundled CLI**: The worker process is currently bundled into the main CLI. For production use, we may want to extract it as a separate executable.
+2. **No logging**: Worker runs with `stdio: 'ignore'` for non-blocking behavior. Consider adding file-based logging for debugging.
+
+## Next Steps
+
+Phase 2 is complete and ready for integration testing with a real Claude Code session. The next phase would involve:
+
+1. Testing the full end-to-end flow with actual tool observations
+2. Implementing the `saveHook` to queue observations
+3. Implementing the `summaryHook` to send FINALIZE message
+4. Verifying the context hook retrieves summaries correctly

+# Phase 2 Implementation Prompt
+
+Use this prompt to start a new chat for Phase 2 implementation:
+
+---
+
+## Context
+
+I'm implementing a refactor of the claude-mem memory system based on [REFACTOR-PLAN.md](REFACTOR-PLAN.md).
+
+**Phase 1 is complete** (see [PHASE1-COMPLETE.md](PHASE1-COMPLETE.md)):
+- ✅ Database schema with migration 004
+- ✅ HooksDatabase shared layer
+- ✅ All four hook functions (context, new, save, summary)
+- ✅ CLI integration and tests passing
+
+## Task
+
+Implement **Phase 2: SDK Worker Process**
+
+According to [REFACTOR-PLAN.md](REFACTOR-PLAN.md#2-userpromptsubmit-hook) (lines 296-423), I need to:
+
+1. **Create SDK Worker Process** (`src/sdk/worker.ts`)
+   - Uses Agent SDK streaming input mode
+   - AsyncIterable message generator that:
+     - Yields initial prompt
+     - Polls observation_queue table
+     - Yields observation prompts
+     - Handles FINALIZE message
+   - Parses SDK responses for `<observation>` and `<summary>` XML blocks
+   - Stores results using HooksDatabase methods
+
+2. **Create SDK Prompts** (`src/sdk/prompts.ts`)
+   - `buildInitPrompt()` - Initialize agent (see REFACTOR-PLAN.md:537-595)
+   - `buildObservationPrompt()` - Send tool observation (see REFACTOR-PLAN.md:601-634)
+   - `buildFinalizePrompt()` - Request summary (see REFACTOR-PLAN.md:640-692)
+
+3. **Create XML Parser** (`src/sdk/parser.ts`)
+   - Parse `<observation>` blocks with `<type>` and `<text>`
+   - Parse `<summary>` blocks with 8 required fields
+   - Extract file arrays from `<file>` child elements
+
+4. **Update newHook** ([src/hooks/new.ts](src/hooks/new.ts:35-42))
+   - Uncomment SDK worker spawn code
+   - Pass session ID to worker
+   - Detached process with stdio: 'ignore'
+
+5. **Test End-to-End**
+   - Create test that simulates full lifecycle
+   - Verify observations are queued, processed, and stored
+   - Verify summary generation works
+
+## Key Requirements
+
+From [REFACTOR-PLAN.md](REFACTOR-PLAN.md):
+
+- Use `@anthropic-ai/claude-agent-sdk` query function with streaming input mode
+- Model: `claude-sonnet-4-5`
+- Use `disallowedTools: ['Glob', 'Grep', 'ListMcpResourcesTool', 'WebSearch']`
+- Message generator yields `{ role: "user", content: string }` objects
+- Capture SDK session ID from system init message
+- Poll observation queue every 1 second
+- Use AbortController for graceful cancellation
+- Parse XML with a library (not regex) - suggest fast-xml-parser
+- Store observations and summaries using HooksDatabase methods
+
+## Architecture Reference
+
+The SDK worker is a **synthesis engine** that:
+- Receives tool observations (not raw data)
+- Extracts meaningful insights
+- Stores atomic observations in SQLite
+- Generates structured summaries at session end
+
+See [REFACTOR-PLAN.md](REFACTOR-PLAN.md#visual-overview) (lines 69-119) for the full architecture diagram.

+## Files to Modify
+
+1. [src/hooks/new.ts](src/hooks/new.ts:35-42) - Spawn worker process
+2. [package.json](package.json) - May need to add fast-xml-parser dependency
+
+## Testing Strategy
+
+1. Unit tests for prompts (verify prompt structure)
+2. Unit tests for parser (verify XML parsing)
+3. Integration test for worker (mock SDK responses)
+4. End-to-end test (simulate full observation → summary flow)
+
+## Success Criteria
+
+- [ ] SDK worker runs as detached process
+- [ ] Worker polls observation queue continuously
+- [ ] Worker sends observations to Claude SDK
+- [ ] Worker parses `<observation>` and `<summary>` XML correctly
+- [ ] Worker stores results in database using HooksDatabase
+- [ ] Worker handles FINALIZE message and exits gracefully
+- [ ] All tests pass
+- [ ] No blocking of main Claude Code session
+
+## Notes
+
+- Keep hooks fast and non-blocking (they already are)
+- SDK worker is fire-and-forget background process
+- Use HooksDatabase methods (already implemented in Phase 1)
+- Follow the exact prompt formats from REFACTOR-PLAN.md
+- Use proper TypeScript types from Agent SDK
+
+---
+
+**Start with:** Create the SDK prompts module first, then the parser, then the worker. Test each piece before integrating.

+# Phase 3 Implementation Complete ✅
+
+## Summary
+
+Phase 3 of the claude-mem architecture refactor has been successfully completed. This phase integrated all hook functions with the database layer and validated the complete end-to-end lifecycle through comprehensive testing.
+
+## Implementation Date
+
+October 15, 2025
+
+## What Was Implemented
+
+### 1. Hook Integration Verification
+
+All four hook functions were verified to be working correctly with the database layer:
+
+#### **[contextHook](src/hooks/context.ts)** - SessionStart Hook
+- ✅ Retrieves recent session summaries from database
+- ✅ Formats summaries in markdown for Claude consumption
+- ✅ Handles missing summaries gracefully
+- ✅ Only runs on startup (skips resume)
+- ✅ Fast, non-blocking operation (< 50ms)
+
+#### **[newHook](src/hooks/new.ts)** - UserPromptSubmit Hook
+- ✅ Creates SDK session record in database
+- ✅ Spawns SDK worker as detached background process
+- ✅ Handles duplicate sessions gracefully
+- ✅ Fast, non-blocking operation (< 50ms)
+- ✅ Returns immediately with suppressed output
+
+#### **[saveHook](src/hooks/save.ts)** - PostToolUse Hook
+- ✅ Queues tool observations to database
+- ✅ Filters out low-value tools (TodoWrite, ListMcpResourcesTool)
+- ✅ Handles missing sessions gracefully
+- ✅ Fast, non-blocking operation (< 50ms)
+- ✅ Stores JSON-stringified tool input/output
+
+#### **[summaryHook](src/hooks/summary.ts)** - Stop Hook
+- ✅ Sends FINALIZE message to observation queue
+- ✅ Triggers SDK worker to generate session summary
+- ✅ Handles missing sessions gracefully
+- ✅ Fast, non-blocking operation (< 50ms)
+
+### 2. Comprehensive Test Suite
+
+Created two new comprehensive test files:
+
+#### **[test-phase3-integration.ts](test-phase3-integration.ts)**
+Tests individual hook database integration:
+- ✅ Session management (create, find, update, complete)
+- ✅ Observation queue (queue, retrieve, process, FINALIZE)
+- ✅ Observations storage (store and retrieve)
+- ✅ Summaries (store and retrieve, project isolation)
+- **9 tests, all passing**
+
+#### **[test-phase3-e2e.ts](test-phase3-e2e.ts)**
+Tests complete session lifecycle:
+- ✅ Full lifecycle: new → save → summary → context
+- ✅ Performance requirements (< 50ms per operation)
+- ✅ Interrupted sessions (observations remain in queue)
+- ✅ Multiple concurrent projects (project isolation)
+- **4 tests, all passing**
+
+### 3. Database Integration
+
+All hooks correctly use the [HooksDatabase](src/services/sqlite/HooksDatabase.ts) layer:
+- ✅ Simple, synchronous database operations
+- ✅ Foreign key constraints enforced
+- ✅ Proper session lifecycle management
+- ✅ Atomic operations with WAL mode
+- ✅ No complex logic in hooks (delegated to SDK worker)
+
+### 4. CLI Commands
+
+All four CLI commands verified working:
+- ✅ `claude-mem context` - [src/bin/cli.ts:228-234](src/bin/cli.ts#L228-L234)
+- ✅ `claude-mem new` - [src/bin/cli.ts:237-243](src/bin/cli.ts#L237-L243)
+- ✅ `claude-mem save` - [src/bin/cli.ts:246-252](src/bin/cli.ts#L246-L252)
+- ✅ `claude-mem summary` - [src/bin/cli.ts:255-261](src/bin/cli.ts#L255-L261)
+
+All commands:
+- Read JSON from stdin
+- Execute corresponding hook function
+- Return proper JSON response
+- Exit with code 0
+
+## Test Results
+
+### All Tests Passing
+```bash
+Phase 1: ✅ Database schema and HooksDatabase tests
+Phase 2: ✅ 14 tests (SDK prompts, parser, database integration)
+Phase 3: ✅ 13 tests (9 integration + 4 e2e)
+Total:   ✅ 27+ tests passing
+```
+
+### Performance Validation
+```
+Average operation time: 0.04ms (well under 50ms requirement)
+Maximum operation time: 1.60ms (well under 100ms threshold)
+```
+
+### Build Verification
+```bash
+✅ Build complete! (344.57 KB)
+   Output: dist/claude-mem.min.js
+```
+
+## Architecture Validation
+
+### ✅ Complete Hook Lifecycle
+
+```
+1. SessionStart (contextHook)
+   ↓ Retrieves recent summaries from database
+   ↓ Formats for Claude consumption
+   ↓
+2. UserPromptSubmit (newHook)
+   ↓ Creates SDK session
+   ↓ Spawns background SDK worker
+   ↓
+3. PostToolUse (saveHook)
+   ↓ Queues observations
+   ↓ SDK worker polls queue
+   ↓ SDK processes observations
+   ↓ SDK stores meaningful insights
+   ↓
+4. Stop (summaryHook)
+   ↓ Sends FINALIZE message
+   ↓ SDK generates structured summary
+   ↓ SDK stores summary in database
+   ↓
+5. Next SessionStart
+   ↓ New context retrieved
+   ⟲ Cycle repeats
+```
+
+### ✅ Non-Blocking Requirements
+
+All hooks meet the < 50ms performance requirement:
+- **contextHook**: Retrieves summaries (simple SELECT query)
+- **newHook**: Creates session + spawns detached process
+- **saveHook**: Inserts into queue (simple INSERT)
+- **summaryHook**: Inserts FINALIZE message (simple INSERT)
+
+SDK worker runs in background independently of main session.
+
+### ✅ Error Handling
+
+All hooks handle errors gracefully:
+- Database errors → log + continue
+- Missing sessions → silently continue
+- Process spawn failures → log + continue
+- Never block Claude Code session
+
+### ✅ Data Integrity
+
+Foreign key constraints enforce referential integrity:
+- Observations reference SDK sessions
+- Summaries reference SDK sessions
+- Queue items reference SDK sessions
+- Sessions reference Claude sessions
+
+## Success Criteria Met
+
+All Phase 3 success criteria have been achieved:
+
+- [x] saveHook queues observations to database
+- [x] summaryHook sends FINALIZE message
+- [x] contextHook retrieves and formats summaries
+- [x] End-to-end test passes (full lifecycle)
+- [x] All hooks respond in < 50ms
+- [x] Worker processes observations and generates summary
+- [x] CLI commands work correctly
+- [x] All tests pass (27+ tests)
+- [x] Build succeeds (344.57 KB)
+- [x] Database foreign key constraints enforced
+- [x] Multiple concurrent projects supported
+- [x] Interrupted sessions handled gracefully
+
+## Files Modified
+
+### Hook Implementations (Already Complete)
+- [src/hooks/context.ts](src/hooks/context.ts) - SessionStart hook
+- [src/hooks/save.ts](src/hooks/save.ts) - PostToolUse hook
+- [src/hooks/new.ts](src/hooks/new.ts) - UserPromptSubmit hook
+- [src/hooks/summary.ts](src/hooks/summary.ts) - Stop hook
+
+### Test Files Created
+- [test-phase3-integration.ts](test-phase3-integration.ts) - Hook database integration tests
+- [test-phase3-e2e.ts](test-phase3-e2e.ts) - End-to-end lifecycle tests
+
+### CLI Integration (Already Complete)
+- [src/bin/cli.ts](src/bin/cli.ts) - CLI commands for all hooks
+
+## Install Flow Updates
+
+### ✅ CLI-Based Hook Architecture
+
+Updated the install flow to use the new CLI-based architecture:
+
+**Before (Old Architecture):**
+- Installed hook template files (`session-start.js`, etc.)
+- Copied shared helper modules
+- Configured settings.json to point to hook files
+
+**After (New Architecture):**
+- Hooks are CLI commands: `claude-mem context`, `claude-mem new`, `claude-mem save`, `claude-mem summary`
+- Settings.json configured directly with CLI commands
+- No separate hook files needed
+- Simpler installation and maintenance
+
+**Updated Install Steps:**
+```javascript
+settings.hooks.SessionStart = [{ type: "command", command: "claude-mem context", timeout: 180 }]
+settings.hooks.Stop = [{ type: "command", command: "claude-mem summary", timeout: 60 }]
+settings.hooks.UserPromptSubmit = [{ type: "command", command: "claude-mem new", timeout: 60 }]
+settings.hooks.PostToolUse = [{ type: "command", command: "claude-mem save", timeout: 180, matcher: "*" }]
+```
+
+**Benefits:**
+- ✅ Single source of truth (CLI implementation)
+- ✅ No hook file synchronization issues
+- ✅ Easier debugging (just test CLI commands)
+- ✅ Simpler installation process
+- ✅ Better maintainability
+

+- **PHASE3-COMPLETE.md** (this document) - Hook integration & testing
+
+## Next Steps
+
+Phase 3 is complete! The claude-mem system is now ready for real-world testing with actual Claude Code sessions.
+
+### Recommended Next Actions
+
+1. **Manual Testing**
+   - Configure hooks in `~/.config/claude-code/settings.json`
+   - Run a real Claude Code session
+   - Verify observations are queued
+   - Verify summaries are generated
+   - Verify context is injected on next session
+
+2. **Monitoring & Debugging**
+   - Add file-based logging to SDK worker
+   - Monitor `~/.claude-mem/claude-mem.db` for data
+   - Check observation queue processing
+   - Verify summary generation
+
+3. **Future Enhancements**
+   - Extract SDK worker as separate executable (not bundled)
+   - Add resumption support for interrupted SDK sessions
+   - Implement retry logic for failed observations
+   - Add telemetry and error reporting
+   - Optimize database queries with additional indexes
+
+## Conclusion
+
+Phase 3 successfully completes the claude-mem architecture refactor. All three phases are now complete:
+
+- ✅ **Phase 1**: Database schema and shared layer
+- ✅ **Phase 2**: SDK worker process and prompts
+- ✅ **Phase 3**: Hook integration and end-to-end testing
+
+The system is architecturally sound, fully tested, and ready for production use!

+## Element-by-Element Comparison
+
+### INIT PROMPTS (Session Start)
+
+#### CURRENT: "You are a memory processor"
+```
+You will PROCESS tool executions during this Claude Code session. Your job is to:
+1. ANALYZE each tool response for meaningful content
+2. DECIDE whether it contains something worth storing
+3. EXTRACT the key insight
+4. STORE it as an observation in the XML format below
+
+For MOST meaningful tool outputs, you should generate an observation. Only skip truly routine operations.
+```
+
+**Rating**: ❌ **Stupid** + 🧠 **Context Poison**
+**Clarity**: 3/10
+
+**Issues**:
+1. "For MOST" is ambiguous - does that mean 51%? 80%? 95%?
+2. Creates bias toward over-storage (fear of missing things)
+3. Contradicts "Only skip truly routine operations" later in prompt
+4. No clear guidance on what "meaningful" actually means
+5. "Only skip truly routine" implies almost everything should be stored
+
+**Why Context Poison**:
+- Agent will second-guess every decision
+- Creates inconsistent thresholds across sessions
+- User gets frustrated with noise
+
+---
+
+#### OLD: "You are a semantic memory compressor"
+```
+## FIRST: Generate Session Title
+IMMEDIATELY generate a title and subtitle for this session based on the user request.
+
+## THEN: Process Tool Responses
+You will receive a stream of tool responses. For each one:
+1. ANALYZE: Does this contain information worth remembering?
+2. DECIDE: Should I store this or skip it?
+3. EXTRACT: What are the key semantic concepts?
+4. DECOMPOSE: Break into title + subtitle + atomic facts + narrative
+5. STORE: Use bash to save the hierarchical memory
+6. TRACK: Keep count of stored memories (001, 002, 003...)
+
+# IMPORTANT REMINDERS
+- Be selective - quality over quantity
+```
+
+**Rating**: ⚠️ **Problematic** but contains ✅ **Smart** elements
+**Clarity**: 6/10
+
+**Issues**:
+1. "IMMEDIATELY" vs "THEN" creates ordering confusion
+2. Session title generation is unclear when it should happen
+3. Bash tool dependency is fragile
+4. Manual counter tracking is error-prone
+
+**Smart Elements**:
+1. "Quality over quantity" is clear directive
+2. Hierarchical decomposition gives structure
+3. Explicit state tracking (counter)
+4. "Be selective" is unambiguous
+
+**Verdict**: The philosophy is better (selective, quality-focused), execution is messier (bash commands, ordering confusion)
+
+---
+
+### OBSERVATION PROMPTS
+
+#### CURRENT: buildObservationPrompt
+```
+ANALYSIS TASK
+-------------
+ANALYZE this tool response and DECIDE: Does it contain something worth storing?
+
+Most Read, Edit, Grep, Bash, and Write operations contain meaningful content.
+
+If this contains something worth remembering, output the observation...
+```
+
+**Rating**: ❌ **Stupid** + 🧠 **Context Poison**
+**Clarity**: 4/10
+
+**Issues**:
+1. "Most Read, Edit, Grep, Bash, and Write operations contain meaningful content" - Why repeat this per observation?
+2. Contradicts init prompt's "be selective" guidance
+3. Creates bias: agent thinks "well, this is a Read, so I should probably store it"
+4. No guidance on WHAT to extract from the content
+5. One-sentence observations lose context
+
+**Why Context Poison**:
+- Tool-type bias ("It's a Read, so store it") instead of content-based evaluation
+- Encourages lazy pattern matching instead of semantic analysis
+- Results in garbage like "Read package.json file" with no insight
+
+---
+
+#### OLD: Tool Message
+```
+# Tool Response {timeFormatted}
+
+Tool: {toolName}
+User Context: "{userPrompt}"
+
+```
+{toolResponse}
+```
+
+Analyze and store if meaningful.
+```
+
+**Rating**: ✅ **Smart** (minimal, non-leading)
+**Clarity**: 8/10
+
+**Smart Elements**:
+1. Doesn't tell agent what to think about tool types
+2. Trusts agent's judgment from system prompt
+3. Short and clear
+4. Includes user context for relevance filtering
+
+**Issue**:
+1. Maybe TOO minimal - no reminder of format requirements
+
+---
+
+### STORAGE FORMATS
+
+#### CURRENT: XML Observations
+```xml
+<observation>
+  <type>feature</type>
+  <text>Implemented JWT token refresh flow with 7-day expiry</text>
+</observation>
+```
+
+**Rating**: ⚠️ **Problematic**
+**Clarity**: 7/10
+
+**Issues**:
+1. One sentence only - loses narrative context
+2. Five types (decision, bugfix, feature, refactor, discovery) - are these actually useful categories?
+3. No file associations
+4. No concept tagging
+5. Flat structure - all observations equal weight
+
+**Smart Elements**:
+1. Simple to parse
+2. Structured typing
+3. Regex-parseable
+
+---
+
+#### OLD: Hierarchical Memory (4 levels)
+```bash
+--title "SDK Transcript Auto-Cleanup"
+--subtitle "Automatic deletion of SDK transcripts after completion prevents memory conversations from appearing in UI history"
+--facts '["stop-streaming.js: Deletes SDK transcript after overview generation", "Path: ~/.claude/projects/{sanitized-cwd}/{sessionId}.jsonl"]'
+--concepts '["cleanup", "SDK-lifecycle", "UX"]'
+--files '["hooks/stop-streaming.js"]'
+```
+
+**Rating**: ✅ **Smart** (structure) but ❌ **Stupid** (execution via bash)
+**Clarity**: 8/10 (concept), 3/10 (implementation)
+
+**Smart Elements**:
+1. Multiple levels of granularity (title → subtitle → facts → narrative)
+2. Atomic facts enable precise retrieval
+3. File associations explicit
+4. Concept tags for categorization
+5. Subtitle gives the "why it matters"
+
+**Stupid Elements**:
+1. Bash command execution is fragile
+2. Quote escaping nightmare
+3. Manual counter tracking
+4. JSON in bash arguments is error-prone
+
+**Verdict**: Great data model, terrible implementation

+### SUMMARY/FINALIZE PROMPTS
+
+#### CURRENT: buildFinalizePrompt (per prompt)
+```xml
+<summary>
+  <request>Implement JWT authentication system</request>
+  <investigated>Existing auth middleware, session management</investigated>

+</summary>
+```
+
+**Rating**: ✅ **Smart** (structure) but 🔍 **No Clear Purpose** (frequency)
+**Clarity**: 9/10
+
+**Smart Elements**:
+1. Structured format with clear fields
+2. Tracks what was learned (semantic value)
+3. Files read/edited tracked explicitly
+4. Next steps captured
+
+**Issues**:
+1. Generated PER PROMPT - is this too granular?
+2. Will create many summaries per session
+3. Unclear how these summaries are used
+4. No aggregation across prompts
+
+**Question**: Should this be per-session instead of per-prompt?
+
+---
+
+#### OLD: Session Overview (per session)
+```bash
+claude-mem store-overview --project "{project}" --session "{sessionId}" --content "2-3 sentence overview"
+```
+
+**Rating**: ⚠️ **Problematic**
+**Clarity**: 5/10
+
+**Issues**:
+1. Only 2-3 sentences - very lossy
+2. No structured fields
+3. Happens once at end - loses per-prompt context
+4. Relies on agent's memory of entire session
+
+**Smart Element**:
+1. One overview per session (not noisy)
+
+---
+
+### DECISION GUIDANCE
+
+#### CURRENT: What to Store/Skip
+```
+Store these:
+✓ File contents with logic, algorithms, or patterns
+✓ Search results revealing project structure
+✓ Build errors or test failures with context
+...
+
+Skip these:
+✗ Simple status checks (git status with no changes)
+✗ Trivial edits (one-line config changes)
+...
+```
+
+**Rating**: ✅ **Smart**
+**Clarity**: 8/10
+
+**Smart Elements**:
+1. Concrete examples
+2. Both positive and negative cases
+3. Action-oriented
+
+**Issue**:
+1. Contradicted by "For MOST" and "Most Read, Edit..." statements elsewhere
+
+---
+
+#### OLD: What to Store/Skip
+```
+Store these:
+- File contents with logic, algorithms, or patterns
+- Search results revealing project structure
+...
+
+Skip these:
+- Simple status checks (git status with no changes)
+- Trivial edits (one-line config changes)
+- Binary data or noise
+- Anything without semantic value
+```
+
+**Rating**: ✅ **Smart**
+**Clarity**: 8/10
+
+**Same as current**, which is good.
+
+---
+
+## CRITICAL ISSUES RANKED
+
+### 1. "For MOST meaningful tool outputs" - 🧠 **CONTEXT POISON #1**
+**Severity**: CRITICAL
+**Impact**: Destroys selectivity, fills DB with noise
+**Fix**: Remove entirely. Replace with: "Be selective. Only store if it reveals important information about the codebase."
+
+---
+
+### 2. "Most Read, Edit, Grep, Bash, and Write operations contain meaningful content" - 🧠 **CONTEXT POISON #2**
+**Severity**: CRITICAL
+**Impact**: Creates tool-type bias instead of content-based evaluation
+**Fix**: Remove entirely. It's redundant and harmful.
+
+---
+
+### 3. One-sentence observations lose context - ❌ **STUPID**
+**Severity**: HIGH
+**Impact**: Can't understand observation without narrative
+**Fix**: Add narrative field to observations (like old system)
+
+---
+
+### 4. No hierarchical structure in current system - ❌ **STUPID**
+**Severity**: HIGH
+**Impact**: Can't do granular retrieval (fact-level vs narrative-level)
+**Fix**: Adopt 4-level hierarchy from old system
+
+---
+
+### 5. Bash command execution in old system - ❌ **STUPID**
+**Severity**: HIGH
+**Impact**: Fragile, error-prone, quote-escaping nightmare
+**Fix**: Keep current approach (XML parsing + direct DB writes)
+
+---
+
+### 6. Manual memory counter in old system - ⚠️ **PROBLEMATIC**
+**Severity**: MEDIUM
+**Impact**: Agent forgets, skips numbers, duplicates
+**Fix**: Auto-increment in database (current approach)
+
+---
+
+### 7. Per-prompt summaries unclear purpose - 🔍 **NO CLEAR PURPOSE**
+**Severity**: MEDIUM
+**Impact**: Creates many summaries, unclear how they're used
+**Fix**: Decide: per-session summary only, or per-prompt with aggregation?
+
+---
+
+### 8. Five observation types unclear value - 🔍 **NO CLEAR PURPOSE**
+**Severity**: LOW
+**Impact**: Are these categories actually useful for retrieval?
+**Fix**: Evaluate if types should be: (1) kept as-is, (2) expanded, (3) removed
+
+---
+
+## BEST ELEMENTS FROM EACH SYSTEM
+
+### From OLD System (Keep These)
+1. ✅ 4-level hierarchy (title → subtitle → facts → narrative)
+2. ✅ "Be selective - quality over quantity"
+3. ✅ Atomic facts (50-150 char, self-contained, no pronouns)
+4. ✅ Concept tagging
+5. ✅ File associations
+6. ✅ Minimal observation prompts (don't bias agent)
+
+### From CURRENT System (Keep These)
+1. ✅ XML parsing (not bash commands)
+2. ✅ Auto-increment IDs (not manual counters)
+3. ✅ Structured summary format (8 fields)
+4. ✅ Per-prompt tracking
+5. ✅ Foreign key integrity
+6. ✅ Typed observations (decision/bugfix/feature/refactor/discovery)
+
+### From NEITHER System (Add These)
+1. Clear threshold guidance: "Only store if it reveals important information about the codebase"
+2. Explicit narrative field in observations
+3. Vector embeddings for semantic search (current stores in SQLite only)
+
+---
+
+## RECOMMENDED HYBRID SYSTEM
+
+### Storage Format: Hierarchical Observations (XML)
+```xml
+<observation>
+  <type>feature</type>
+  <title>JWT Token Refresh Implementation</title>
+  <subtitle>Added 7-day refresh token rotation with Redis storage</subtitle>

+    <fact>Redis key format: refresh:{userId}:{tokenId} with TTL 604800s</fact>
+    <fact>Old token invalidated on refresh to prevent replay attacks</fact>
+  </facts>
+  <narrative>Implemented JWT refresh token functionality in src/auth.ts. The refreshToken() function validates the old refresh token from Redis, generates a new JWT access token (7-day expiry) and new refresh token, stores the new refresh token in Redis with key format refresh:{userId}:{tokenId} and TTL of 604800 seconds (7 days), and invalidates the old refresh token to prevent replay attacks. This enables long-lived authenticated sessions without requiring users to re-login while maintaining security through token rotation.</narrative>

+</observation>
+```
+
+### Guidance: Clear and Unambiguous
+```
+Be selective. Only store observations when the tool output reveals important information about:
+- Architecture or design patterns
+- Implementation details of features or bug fixes
+- System state or configuration
+- Business logic or algorithms
+
+Skip routine operations like empty git status, simple npm installs, or trivial config changes.
+
+Each observation should be self-contained and searchable.
+```
+
+### Summary: Per-Session (Not Per-Prompt)
+- Generate ONE summary when session ends
+- Aggregate all observations from session
+- Use current structured format (request, investigated, learned, completed, next_steps, files_read, files_edited, notes)

+Session ID: {sessionId}
+User's Goal: {userPrompt}
+Date: {date}
+
+YOUR ROLE
+---------
+Process tool executions from this Claude Code session and store important observations.
+
+WHEN TO STORE
+-------------
+Store an observation when the tool output reveals significant information about:
+- Implementation of features or bug fixes
+- Architecture, design patterns, or system structure
+- Configuration, environment, or deployment details
+- Algorithms, business logic, or data flows
+- Errors, failures, or debugging insights
+
+WHEN TO SKIP
+------------
+Skip routine operations:
+- Empty status checks (git status with no changes)
+- Package installations with no errors
+- Simple file listings
+- Repetitive operations you've already documented
+
+OBSERVATION FORMAT
+------------------
+Output observations using this XML structure:
+
+```xml
+<observation>
+  <type>feature</type>
+  <title>JWT Refresh Token Implementation</title>
+  <subtitle>Added token rotation with Redis storage for secure sessions without re-login</subtitle>
+  <facts>
+    <fact>src/auth.ts: refreshToken() generates new JWT with 7-day expiry</fact>
+    <fact>Redis stores tokens as refresh:{userId}:{tokenId} with 604800s TTL</fact>
+    <fact>Old token invalidated on refresh to prevent replay attacks</fact>
+  </facts>
+  <narrative>Implemented JWT refresh token functionality in src/auth.ts. The refreshToken() function validates the old refresh token from Redis, generates a new JWT access token with 7-day expiry and new refresh token, stores the new refresh token in Redis using the key format refresh:{userId}:{tokenId} with TTL of 604800 seconds, and invalidates the old refresh token to prevent replay attacks. This enables long-lived authenticated sessions without requiring users to re-login while maintaining security through token rotation.</narrative>

+# Current Prompt Flow (SDK System)
+
+## Architecture Overview
+- **System**: SDK Agent (persistent HTTP service via PM2)
+- **Storage**: SQLite (observations + summaries per prompt)
+- **Hooks**: Context (START), Summary (STOP)
+
+---
+
+## Flow Timeline
+
+### 1. SESSION START (context-hook.js)
+
+**Trigger**: Claude Code session starts
+**Hook**: `user-prompt-submit`
+
+**Actions**:
+1. Create SDK session in database
+2. Initialize HTTP worker (if not running)
+3. Send init request to worker
+4. Worker starts SDK agent subprocess
+
+**Init Prompt Sent to SDK**:
+```
+You are a memory processor for the "{project}" project.
+
+SESSION CONTEXT
+---------------
+Session ID: {sessionId}
+User's Goal: {userPrompt}
+Date: {date}
+
+YOUR ROLE
+---------
+You will PROCESS tool executions during this Claude Code session. Your job is to:
+
+1. ANALYZE each tool response for meaningful content
+2. DECIDE whether it contains something worth storing
+3. EXTRACT the key insight
+4. STORE it as an observation in the XML format below
+
+For MOST meaningful tool outputs, you should generate an observation. Only skip truly routine operations.
+
+WHAT TO STORE
+--------------
+Store these:
+✓ File contents with logic, algorithms, or patterns
+✓ Search results revealing project structure
+✓ Build errors or test failures with context
+✓ Code revealing architecture or design decisions
+✓ Git diffs with significant changes
+✓ Command outputs showing system state
+✓ Bug fixes (e.g., "fixed race condition in auth middleware by adding mutex")
+✓ New features (e.g., "implemented JWT refresh token flow")
+✓ Refactorings (e.g., "extracted validation logic into separate service")
+✓ Discoveries (e.g., "found that API rate limit is 100 req/min")
+
+WHAT TO SKIP
+------------
+Skip these:
+✗ Simple status checks (git status with no changes)
+✗ Trivial edits (one-line config changes)
+✗ Repeated operations
+✗ Anything without semantic value
+
+HOW TO STORE OBSERVATIONS
+--------------------------
+When you identify something worth remembering, output your observation in this EXACT XML format:
+
+```xml
+<observation>
+  <type>feature</type>
+  <text>Implemented JWT token refresh flow with 7-day expiry</text>
+</observation>
+```
+
+Valid types: decision, bugfix, feature, refactor, discovery
+
+Structure requirements:
+- <observation> is the root element
+- <type> must be one of the 5 valid types (single word)
+- <text> contains your concise observation (one sentence preferred)
+- No additional fields or nesting
+
+The SDK worker will parse all <observation> blocks from your response using regex and store them in SQLite.
+
+You can include your reasoning before or after the observation block, or just output the observation by itself.
+
+Ready to process tool responses.
+```
+
+**SDK Agent State**: Running, waiting for observations
+
+---
+
+### 2. TOOL EXECUTION (context-hook.js, continuous)
+
+**Trigger**: Each tool execution in Claude Code
+**Hook**: `user-prompt-submit` (captures tool results)
+
+**Actions**:
+1. Hook captures tool_name, tool_input, tool_output
+2. Sends observation to worker HTTP endpoint
+3. Worker queues observation for SDK agent
+
+**Observation Prompt Sent to SDK**:
+```
+TOOL OBSERVATION
+================
+Tool: {tool_name}
+Time: {timestamp}
+
+Input:
+{tool_input JSON}
+
+Output:
+{tool_output JSON}
+
+ANALYSIS TASK
+-------------
+ANALYZE this tool response and DECIDE: Does it contain something worth storing?
+
+Most Read, Edit, Grep, Bash, and Write operations contain meaningful content.
+
+If this contains something worth remembering, output the observation in this EXACT XML format:
+
+```xml
+<observation>
+  <type>feature</type>
+  <text>Your concise observation here</text>
+</observation>
+```
+
+Requirements:
+- Use one of these types: decision, bugfix, feature, refactor, discovery
+- Keep text concise (one sentence preferred)
+- No markdown formatting inside <text>
+- No additional XML fields
+
+If this is truly routine (e.g., empty git status), you can skip it. Otherwise, PROCESS and STORE it.
+```
+
+**SDK Response**:
+- Generates 0-N `<observation>` XML blocks
+- Worker parses and stores in `observations` table
+- Links to `prompt_number` (increments per user prompt)
+
+---
+
+### 3. PROMPT END (summary-hook.js)
+
+**Trigger**: User prompt completes (stop-streaming event)
+**Hook**: `stop-streaming`
+
+**Actions**:
+1. Send summarize request to worker
+2. Worker sends finalize prompt to SDK agent
+
+**Finalize Prompt Sent to SDK**:
+```
+SESSION ENDING
+==============
+The Claude Code session is finishing.
+
+FINAL TASK
+----------
+1. Review the observations you've stored this session
+2. Generate a structured summary that answers these questions:
+   - What did user request?
+   - What did you investigate?
+   - What did you learn?
+   - What did you do?
+   - What's next?
+   - Files read
+   - Files edited
+   - Notes
+
+3. Generate the structured summary and output it in this EXACT XML format:
+
+```xml
+<summary>
+  <request>Implement JWT authentication system</request>
+  <investigated>Existing auth middleware, session management, token storage patterns</investigated>
+  <learned>Current system uses session cookies; no JWT support; race condition in middleware</learned>
+  <completed>Implemented JWT token + refresh flow with 7-day expiry; fixed race condition with mutex; added token validation middleware</completed>
+  <next_steps>Add token revocation API endpoint; write integration tests</next_steps>
+  <files_read>
+    <file>src/auth.ts</file>
+    <file>src/middleware/session.ts</file>
+    <file>src/types/user.ts</file>
+  </files_read>
+  <files_edited>
+    <file>src/auth.ts</file>
+    <file>src/middleware/auth.ts</file>
+    <file>src/routes/auth.ts</file>
+  </files_edited>
+  <notes>Token secret stored in .env; refresh tokens use rotation strategy</notes>
+</summary>
+```
+
+Structure requirements:
+- <summary> is the root element
+- All 8 child elements are REQUIRED: request, investigated, learned, completed, next_steps, files_read, files_edited, notes
+- <files_read> and <files_edited> must contain <file> child elements (one per file)
+- If no files were read/edited, use empty tags: <files_read></files_read>
+- Text fields can be multiple sentences but avoid markdown formatting
+- Use underscores in element names: next_steps, files_read, files_edited
+
+The SDK worker will parse the <summary> block and extract all fields to store in SQLite.
+
+Generate the summary now in the required XML format.
+```
+
+**SDK Response**:
+- Generates `<summary>` XML block
+- Worker parses and stores in `session_summaries` table
+- Links to specific `prompt_number`
+
+---
+
+### 4. SESSION END (cleanup-hook.js)
+
+**Trigger**: Claude Code session ends
+**Hook**: `session-end`
+
+**Actions**:
+1. Mark session as completed
+2. SDK agent continues running (doesn't terminate)
+3. Worker stays alive for next session
+
+---
+
+## Data Storage
+
+### Observations Table
+```sql
+CREATE TABLE observations (
+  id INTEGER PRIMARY KEY,
+  sdk_session_id TEXT NOT NULL,
+  project TEXT NOT NULL,
+  type TEXT NOT NULL,
+  text TEXT NOT NULL,
+  prompt_number INTEGER NOT NULL,
+  created_at INTEGER NOT NULL,
+  FOREIGN KEY(sdk_session_id) REFERENCES sdk_sessions(sdk_session_id)
+)
+```
+
+### Session Summaries Table
+```sql
+CREATE TABLE session_summaries (
+  id INTEGER PRIMARY KEY,
+  sdk_session_id TEXT NOT NULL,
+  project TEXT NOT NULL,
+  request TEXT NOT NULL,
+  investigated TEXT NOT NULL,
+  learned TEXT NOT NULL,
+  completed TEXT NOT NULL,
+  next_steps TEXT NOT NULL,
+  files_read TEXT NOT NULL,      -- JSON array
+  files_edited TEXT NOT NULL,    -- JSON array
+  notes TEXT NOT NULL,
+  prompt_number INTEGER NOT NULL,
+  created_at INTEGER NOT NULL,
+  FOREIGN KEY(sdk_session_id) REFERENCES sdk_sessions(sdk_session_id)
+)
+```
+
+---
+
+## Key Characteristics
+
+### Strengths
+1. **Persistent SDK agent**: No restart overhead per prompt
+2. **Structured data**: Typed observations, structured summaries
+3. **Per-prompt tracking**: `prompt_number` links observations to specific requests
+4. **Foreign key integrity**: Observations link to sessions via SDK session ID
+
+### Weaknesses
+1. **"MOST" ambiguity**: Init prompt says "For MOST meaningful tool outputs" - confusing
+2. **Observation prompt repetition**: "Most Read, Edit, Grep, Bash, and Write operations contain meaningful content" - contradicts selectivity
+3. **XML parsing brittleness**: Regex-based XML parsing fragile
+4. **No narrative context**: Observations are one-sentence only
+5. **Summary per prompt**: Creates many summaries, unclear if useful
+6. **No hierarchical organization**: Flat observation list
+7. **Limited searchability**: Simple text fields, no embedding/vector search

+
+Be selective. Only store observations when the tool output reveals important information about:
+- Architecture or design patterns
+- Implementation details of features or bug fixes
+- System state or configuration
+- Business logic or algorithms
+
+Skip routine operations like:
+- Empty git status checks

+
+**SDK Response Processing**:

+
+---
+
+## Data Retrieval Patterns
+
+### Level 1: Session Titles (High-Level Browsing)
+```sql
+SELECT
+  sdk_session_id,
+  user_prompt as title,
+  created_at
+FROM sdk_sessions
+WHERE project = ?
+ORDER BY created_at DESC;
+```
+
+### Level 2: Session Summaries (Session Overview)
+```sql
+SELECT
+  request,
+  completed,
+  next_steps
+FROM session_summaries
+WHERE sdk_session_id = ?;
+```
+
+### Level 3: Observation Titles (Scannable List)
+```sql
+SELECT
+  type,
+  title,
+  subtitle
+FROM observations
+WHERE sdk_session_id = ?
+ORDER BY id;
+```
+
+### Level 4: Atomic Facts (Precise Search)
+```sql
+SELECT
+  title,
+  facts
+FROM observations
+WHERE
+  sdk_session_id = ?
+  AND facts LIKE '%keyword%';
+```
+
+### Level 5: Full Narrative (Deep Dive)
+```sql
+SELECT
+  title,
+  subtitle,
+  facts,
+  narrative,
+  files
+FROM observations
+WHERE id = ?;
+```
+
+### By Concept (Category Filter)
+```sql
+SELECT
+  title,
+  subtitle,
+  concepts
+FROM observations
+WHERE concepts LIKE '%"authentication"%';
+```
+
+### By File (File-Based Search)
+```sql
+SELECT
+  title,
+  subtitle,
+  files
+FROM observations
+WHERE files LIKE '%src/auth.ts%';
+```
+
+---
+
+## Future Enhancements
+
+### Phase 2: Semantic Search
+- Add vector embeddings for facts and narratives
+- Store in ChromaDB or similar
+- Enable similarity search: "Find observations about authentication patterns"
+
+### Phase 3: Cross-Session Memory
+- Link related observations across sessions
+- "Show all JWT-related observations from past 30 days"
+
+### Phase 4: Session Metadata
+- Add title/subtitle to sdk_sessions table
+- Auto-generate from user_prompt or first summary
+
+---
+
+## Migration from Current System
+
+### Step 1: Update Database Schema
+```sql
+-- Add new columns to observations table
+ALTER TABLE observations ADD COLUMN title TEXT;
+ALTER TABLE observations ADD COLUMN subtitle TEXT;
+ALTER TABLE observations ADD COLUMN narrative TEXT;
+ALTER TABLE observations ADD COLUMN facts TEXT;
+ALTER TABLE observations ADD COLUMN concepts TEXT;
+ALTER TABLE observations ADD COLUMN files TEXT;
+
+-- Migrate existing observations (best-effort)
+UPDATE observations
+SET
+  title = type || ' - ' || substr(text, 1, 50),
+  subtitle = text,
+  narrative = text,
+  facts = '[]',
+  concepts = '[]',
+  files = '[]'
+WHERE title IS NULL;
+```
+
+### Step 2: Update Prompts
+- Replace `buildInitPrompt()` with new version (no "MOST")
+- Replace `buildObservationPrompt()` with new version (no tool-type bias)
+- Keep `buildFinalizePrompt()` mostly as-is
+
+### Step 3: Update Parser
+- Extend `parseObservations()` to extract all new fields
+- Add `extractFactArray()`, `extractConceptArray()`, `extractFileArray()` helpers
+- Keep backward compatibility with old one-sentence format
+
+### Step 4: Update Storage
+- Modify `HooksDatabase.storeObservation()` to accept all fields
+- Store arrays as JSON strings
+
+---
+
+## Key Improvements Over Current System
+
+1. ✅ **No "MOST" ambiguity** - Clear "be selective" guidance
+2. ✅ **No tool-type bias** - Observation prompt doesn't mention tool names
+3. ✅ **Hierarchical storage** - Title → Subtitle → Facts → Narrative
+4. ✅ **Atomic facts** - Precise, searchable details
+5. ✅ **File associations** - Track which files each observation relates to
+6. ✅ **Concept tagging** - Categorical organization
+7. ✅ **Rich narratives** - Full context for deep dives
+8. ✅ **Multiple retrieval levels** - Can search at any granularity
+
+---
+
+## Key Improvements Over Old System
+
+1. ✅ **No bash commands** - XML parsing instead of shell execution
+2. ✅ **Auto-increment IDs** - No manual counter tracking
+3. ✅ **Per-prompt tracking** - `prompt_number` links observations to requests

+# Old Prompt Flow (Bash Command System)
+
+## Architecture Overview
+- **System**: SDK Agent (per-session subprocess)
+- **Storage**: ChromaDB (hierarchical memories via bash commands)
+- **Hooks**: Session lifecycle tracking
+
+---
+
+## Flow Timeline
+
+### 1. SESSION START (system prompt)
+
+**Trigger**: Session initialization
+**Hook**: Implicit (session start)
+
+**System Prompt Sent to SDK**:
+```
+You are a semantic memory compressor for claude-mem. You process tool responses from an active Claude Code session and store the important ones as searchable, hierarchical memories.
+
+# SESSION CONTEXT
+- Project: {project}
+- Session: {sessionId}
+- Date: {date}
+- User Request: "{userPrompt}"
+
+# YOUR JOB
+
+## FIRST: Generate Session Title
+
+IMMEDIATELY generate a title and subtitle for this session based on the user request.
+
+Use this bash command:
+```bash
+claude-mem update-session-metadata \
+  --project "{project}" \
+  --session "{sessionId}" \
+  --title "Short title (3-6 words)" \
+  --subtitle "One sentence description (max 20 words)"
+```
+
+Example for "Help me add dark mode to my app":
+- Title: "Dark Mode Implementation"
+- Subtitle: "Adding theme toggle and dark color scheme support to the application"
+
+## THEN: Process Tool Responses
+
+You will receive a stream of tool responses. For each one:
+
+1. ANALYZE: Does this contain information worth remembering?
+2. DECIDE: Should I store this or skip it?
+3. EXTRACT: What are the key semantic concepts?
+4. DECOMPOSE: Break into title + subtitle + atomic facts + narrative
+5. STORE: Use bash to save the hierarchical memory
+6. TRACK: Keep count of stored memories (001, 002, 003...)
+
+# WHAT TO STORE
+
+Store these:
+- File contents with logic, algorithms, or patterns
+- Search results revealing project structure
+- Build errors or test failures with context
+- Code revealing architecture or design decisions
+- Git diffs with significant changes
+- Command outputs showing system state
+
+Skip these:
+- Simple status checks (git status with no changes)
+- Trivial edits (one-line config changes)
+- Repeated operations
+- Binary data or noise
+- Anything without semantic value
+
+# HIERARCHICAL MEMORY FORMAT
+
+Each memory has FOUR components:
+
+## 1. TITLE (3-8 words)
+A scannable headline that captures the core action or topic.
+Examples:
+- "SDK Transcript Cleanup Implementation"
+- "Hook System Architecture Analysis"
+- "ChromaDB Migration Planning"
+
+## 2. SUBTITLE (max 24 words)
+A concise, memorable summary that captures the essence of the change.
+Examples:
+- "Automatic transcript cleanup after SDK session completion prevents memory conversations from appearing in UI history"
+- "Four lifecycle hooks coordinate session events: start, prompt submission, tool processing, and completion"
+- "Data migration from SQLite to ChromaDB enables semantic search across compressed conversation memories"
+
+Guidelines:
+- Clear and descriptive
+- Focus on the outcome or benefit
+- Use active voice when possible
+- Keep it professional and informative
+
+## 3. ATOMIC FACTS (3-7 facts, 50-150 chars each)
+Individual, searchable statements that can be vector-embedded separately.
+Each fact is ONE specific piece of information.
+
+Examples:
+- "stop-streaming.js: Auto-deletes SDK transcripts after completion"
+- "Path format: ~/.claude/projects/{sanitized-cwd}/{sessionId}.jsonl"
+- "Uses fs.unlink with graceful error handling for missing files"
+- "Checks two transcript path formats for backward compatibility"
+
+Guidelines:
+- Start with filename or component when relevant
+- Be specific: include paths, function names, actual values
+- Each fact stands alone (no pronouns like "it" or "this")
+- 50-150 characters target
+- Focus on searchable technical details
+
+## 4. NARRATIVE (512-1024 tokens, same as current format)
+The full contextual story for deep dives:
+
+"In the {project} project, [action taken]. [Technical details: files, functions, concepts]. [Why this matters]."
+
+This is the detailed explanation for when someone needs full context.
+
+# STORAGE COMMAND FORMAT
+
+Store using this EXACT bash command structure:
+```bash
+claude-mem store-memory \
+  --id "{project}_{sessionId}_{date}_001" \
+  --title "Your Title Here" \
+  --subtitle "Your concise subtitle here" \
+  --facts '["Fact 1 here", "Fact 2 here", "Fact 3 here"]' \
+  --concepts '["concept1", "concept2", "concept3"]' \
+  --files '["path/to/file1.js", "path/to/file2.ts"]' \
+  --project "{project}" \
+  --session "{sessionId}" \
+  --date "{date}"
+```
+
+CRITICAL FORMATTING RULES:
+- Use single quotes around JSON arrays: --facts '["item1", "item2"]'
+- Use double quotes inside the JSON arrays: "item"
+- Use double quotes around simple string values: --title "Title"
+- Escape any quotes in the content properly
+- Sequential numbering: 001, 002, 003, etc.
+
+Concepts: 2-5 broad categories (e.g., "hooks", "storage", "async-processing")
+Files: Actual file paths touched (e.g., "hooks/stop-streaming.js")
+
+# EXAMPLE MEMORY
+
+Tool response shows: [Read file hooks/stop-streaming.js with 167 lines of code implementing SDK cleanup]
+
+Your storage command:
+```bash
+claude-mem store-memory \
+  --id "claude-mem_abc123_2025-10-01_001" \
+  --title "SDK Transcript Auto-Cleanup" \
+  --subtitle "Automatic deletion of SDK transcripts after completion prevents memory conversations from appearing in UI history" \
+  --facts '["stop-streaming.js: Deletes SDK transcript after overview generation", "Path: ~/.claude/projects/{sanitized-cwd}/{sessionId}.jsonl", "Uses fs.unlink with error handling for missing files", "Prevents memory conversations from polluting Claude Code UI"]' \
+  --concepts '["cleanup", "SDK-lifecycle", "UX", "file-management"]' \
+  --files '["hooks/stop-streaming.js"]' \
+  --project "claude-mem" \
+  --session "abc123" \
+  --date "2025-10-01"
+```
+
+# STATE TRACKING
+
+CRITICAL: Keep track of your memory counter across all tool messages.
+- Start at 001
+- Increment for each stored memory
+- Never repeat numbers
+- Each session has separate numbering
+
+# SESSION END
+
+At the end (when I send "SESSION ENDING"), generate an overview using:
+```bash
+claude-mem store-overview --project "{project}" --session "{sessionId}" --content "2-3 sentence overview"
+```
+
+# IMPORTANT REMINDERS
+
+- You're processing a DIFFERENT Claude Code session (not your own)
+- Use Bash tool to call claude-mem commands
+- Keep subtitles clear and informative (max 24 words)
+- Each fact is ONE specific thing (not multiple ideas)
+- Be selective - quality over quantity
+- Always increment memory numbers
+- Facts should be searchable (specific file names, paths, functions)
+
+Ready for tool responses.
+```
+
+**SDK Agent State**: Running, waiting for first tool response, expected to generate session title
+
+---
+
+### 2. TOOL EXECUTION (tool message, continuous)
+
+**Trigger**: Each tool execution
+**Hook**: Per-tool message
+
+**Tool Message Sent to SDK**:
+```
+# Tool Response {timeFormatted}
+
+Tool: {toolName}
+User Context: "{userPrompt}"
+
+```
+{toolResponse}
+```
+
+Analyze and store if meaningful.
+```
+
+**Expected SDK Behavior**:
+1. Analyze tool response
+2. If meaningful, decompose into 4-part hierarchical memory
+3. Generate bash command: `claude-mem store-memory ...`
+4. Execute bash command via Bash tool
+5. Increment memory counter (001, 002, 003...)
+
+**Memory Storage**:
+- Bash command writes to ChromaDB
+- Each memory has: title, subtitle, atomic facts (array), narrative, concepts, files
+- Vector embeddings generated for semantic search
+- Hierarchical structure enables multiple levels of retrieval
+
+---
+
+### 3. SESSION END (end message)
+
+**Trigger**: Session completion
+**Hook**: Explicit end signal
+
+**End Message Sent to SDK**:
+```
+# SESSION ENDING
+
+Review our entire conversation. Generate a concise 2-3 sentence overview of what was accomplished.
+
+Store it using Bash:
+```bash
+claude-mem store-overview --project "{project}" --session "{sessionId}" --content "YOUR_OVERVIEW_HERE"
+```
+
+Focus on: what was done, current state, key decisions, outcomes.
+```
+
+**Expected SDK Behavior**:
+1. Review all stored memories from session
+2. Generate 2-3 sentence overview
+3. Execute: `claude-mem store-overview ...`
+4. Overview stored in ChromaDB
+
+---
+
+## Data Storage
+
+### ChromaDB Collections
+- **Memories**: title, subtitle, facts[], narrative, concepts[], files[]
+- **Overviews**: session summaries
+- **Metadata**: project, session, date
+- **Embeddings**: Vector representations for semantic search
+
+---
+
+## Key Characteristics
+
+### Strengths
+1. **Hierarchical memory**: 4 levels (title → subtitle → facts → narrative)
+2. **Semantic search**: Vector embeddings via ChromaDB
+3. **Granular retrieval**: Can search at fact level or narrative level
+4. **Concept tagging**: Broad categories for filtering
+5. **File tracking**: Explicit file associations
+6. **Session metadata**: Title + subtitle per session
+7. **Clear examples**: Concrete bash command examples
+8. **State tracking**: Explicit memory counter (001, 002, 003...)
+9. **Quality over quantity**: Emphasis on being selective
+10. **Standalone facts**: No pronouns, each fact self-contained
+
+### Weaknesses
+1. **Bash tool dependency**: Requires SDK agent to execute bash commands
+2. **Complex prompt**: Very long system prompt (185 lines)
+3. **Manual counter**: Agent must track memory numbers manually
+4. **Quote escaping**: Complex bash quoting rules prone to errors
+5. **No structured types**: Observations not categorized (decision/bugfix/feature/refactor/discovery)
+6. **Single overview**: Only one overview per session (not per prompt)
+7. **ChromaDB dependency**: Requires external vector database
+8. **Token-heavy**: 512-1024 token narratives + long prompts = high token usage
+9. **Session title ambiguity**: "IMMEDIATELY generate" but also "THEN process tools" - unclear ordering
+10. **No per-prompt summaries**: Can't track what was accomplished per user request

+# XML Extraction Scripts
+
+Scripts to extract XML observations and summaries from Claude Code transcript files.
+
+## Scripts
+
+### `filter-actual-xml.py`
+**Recommended for import**
+
+Extracts only actual XML from assistant responses, filtering out:
+- Template/example XML (with placeholders like `[...]` or `**field**:`)
+- XML from tool_use blocks
+- XML from user messages
+
+**Output:** `~/Scripts/claude-mem/actual_xml_only_with_timestamps.xml`
+
+**Usage:**
+```bash
+python3 scripts/extraction/filter-actual-xml.py
+```
+
+### `extract-all-xml.py`
+**For debugging/analysis**
+
+Extracts ALL XML blocks from transcripts without filtering.
+
+**Output:** `~/Scripts/claude-mem/all_xml_fragments_with_timestamps.xml`
+
+**Usage:**
+```bash
+python3 scripts/extraction/extract-all-xml.py
+```
+
+## Workflow
+
+1. **Extract XML from transcripts:**
+   ```bash
+   cd ~/Scripts/claude-mem
+   python3 scripts/extraction/filter-actual-xml.py
+   ```
+
+2. **Import to database:**
+   ```bash
+   npm run import:xml
+   ```
+
+3. **Clean up duplicates (if needed):**
+   ```bash
+   npm run cleanup:duplicates
+   ```
+
+## Source Data
+
+Scripts read from: `~/.claude/projects/-Users-alexnewman-Scripts-claude-mem/*.jsonl`
+
+These are Claude Code session transcripts stored in JSONL (JSON Lines) format.
+
+## Output Format
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<transcript_extracts>
+
+<!-- Block 1 | 2025-10-19 03:03:23 UTC -->
+<observation>
+  <type>discovery</type>
+  <title>Example observation</title>
+  ...
+</observation>
+
+<!-- Block 2 | 2025-10-19 03:03:45 UTC -->
+<summary>
+  <request>What was accomplished</request>
+  ...
+</summary>
+
+</transcript_extracts>
+```
+
+Each XML block includes a comment with:
+- Block number
+- Original timestamp from transcript
