-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

+  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

-## 💻 How It Works
+### Hook System
 
-### The Memory Lifecycle
+claude-mem integrates with Claude Code via streaming hooks that capture conversation events:
 
-1. **🎬 Session Start**: Claude-mem loads relevant context from your knowledge base
-2. **💬 Active Session**: You work normally in Claude Code - no changes needed
-3. **🗜️ Memory Compression**: Use `/compact` or `/clear` to trigger intelligent compression
-4. **🧠 Knowledge Extraction**: AI analysis extracts key learnings and patterns
-5. **💾 Persistent Storage**: Memories stored in searchable vector database
-6. **🔄 Context Ready**: Next session starts with relevant memories loaded
+- **user-prompt-submit** - Captures user prompts in real-time
+- **post-tool-use** - Spawns Agent SDK for async compression
+- **stop-streaming** - Generates session overview and cleanup
+- **session-start** - Loads relevant context automatically
 
-### Technical Architecture
+Hooks are configured during installation with a 180-second timeout and run transparently in the background.
 
-- **Vector Database**: ChromaDB for semantic search and storage
-- **MCP Integration**: Model Context Protocol for Claude Code communication
-- **AI Analysis**: Advanced prompt engineering for knowledge extraction
-- **Local Storage**: All data stored locally in `~/.claude-mem/`

+# Windows Installation Guide
+
+## Overview
+
+Claude-mem now includes **experimental Windows support** as of v3.10.0 (October 2025). The cross-platform architecture uses the [Platform utility](/src/utils/platform.ts) for handling Windows-specific differences.
+
+## System Requirements
+
+- **Windows 10/11** (64-bit recommended)
+- **Node.js** >= 18.0.0
+- **PowerShell** 5.1 or later (for hook execution)
+- **Claude Code** with MCP support
+- **npm** package manager
+
+**Note**: Bun (>=1.0.0) is only required for development work on claude-mem itself, not for running it.
+
+## Known Windows-Specific Differences
+
+### 1. Hook Execution
+- **Unix/macOS**: Hooks execute via `/bin/sh`
+- **Windows**: Hooks execute via `powershell`
+
+All hooks are `.js` files that work on both platforms through Node.js.
+
+### 2. Path Handling
+Windows paths use backslashes (`\`) but Node.js normalizes these automatically. The data directory is located at:
+```
+C:\Users\YourUsername\.claude-mem\
+```
+
+### 3. File Permissions
+- **Unix/macOS**: Hook files get `chmod 755` permissions
+- **Windows**: Permission setting is a no-op (not needed)
+
+### 4. Smart Trash™ Alias
+The Smart Trash feature creates shell aliases differently:
+
+**Windows (PowerShell)**:
+```powershell
+# claude-mem smart trash alias
+function rm { claude-mem trash $args }
+```
+
+PowerShell profiles are located at:
+- `Documents\PowerShell\Microsoft.PowerShell_profile.ps1`
+- `Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1`
+
+**Unix/macOS (Bash/Zsh)**:
+```bash
+# claude-mem smart trash alias
+alias rm='claude-mem trash'
+```
+
+### 5. UV Package Manager Installation
+The installer automatically installs `uv` using platform-specific methods:
+
+**Windows**:
+```powershell
+powershell -Command "irm https://astral.sh/uv/install.ps1 | iex"
+```
+
+**Unix/macOS**:
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+## Installation Steps
+
+### 1. Install claude-mem globally
+
+```powershell
+npm install -g claude-mem
+```
+
+### 2. Run the installer
+
+```powershell
+claude-mem install
+```
+
+The installer will:
+1. ✅ Create directory structure at `C:\Users\YourUsername\.claude-mem\`
+2. ✅ Install UV package manager via PowerShell
+3. ✅ Install Chroma MCP server for vector database
+4. ✅ Add CLAUDE.md instructions to `C:\Users\YourUsername\.claude\`
+5. ✅ Install slash commands (save.md, remember.md, claude-mem.md)
+6. ✅ Install memory hooks with PowerShell execution support
+7. ✅ Configure Claude Code settings
+
+### 3. Restart Claude Code
+
+After installation, restart Claude Code to activate the memory system.
+
+## Windows-Specific Caveats
+
+### PowerShell Execution Policy
+If hooks fail to execute, you may need to adjust your PowerShell execution policy:
+
+```powershell
+# Check current policy
+Get-ExecutionPolicy
+
+# Allow local scripts (choose one):
+Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+# OR for more security:
+Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process
+```
+
+### Path Environment Variable
+After installing UV, you may need to restart PowerShell or update your PATH:
+
+```powershell
+# Add to PATH if needed
+$env:PATH = "$env:USERPROFILE\.cargo\bin;$env:PATH"
+```
+
+The installer attempts to set this automatically, but it only affects the current process.
+
+### Better-SQLite3 Native Module
+The hooks use `better-sqlite3` for database access, which requires native compilation:
+- The installer runs `npm install` in the hooks directory
+- If this fails, hooks may still work if `better-sqlite3` is globally available
+- Build errors are silently ignored to prevent installation failure
+
+If you see database errors in logs:
+```powershell
+cd $env:USERPROFILE\.claude-mem\hooks
+npm install better-sqlite3 --build-from-source
+```
+
+## File Locations on Windows
+
+| Component | Windows Path |
+|-----------|-------------|
+| Data directory | `C:\Users\YourUsername\.claude-mem\` |
+| ChromaDB | `C:\Users\YourUsername\.claude-mem\chroma\` |
+| SQLite database | `C:\Users\YourUsername\.claude-mem\claude-mem.db` |
+| Hooks | `C:\Users\YourUsername\.claude-mem\hooks\` |
+| Archives | `C:\Users\YourUsername\.claude-mem\archives\` |
+| Trash | `C:\Users\YourUsername\.claude-mem\trash\` |
+| CLAUDE.md | `C:\Users\YourUsername\.claude\CLAUDE.md` |
+| Settings | `C:\Users\YourUsername\AppData\Roaming\Claude\settings.json` |
+| Commands | `C:\Users\YourUsername\.claude\commands\` |
+
+## Testing Your Installation
+
+### 1. Check installation status
+```powershell
+claude-mem status
+```
+
+### 2. Run diagnostics
+```powershell
+claude-mem doctor
+```
+
+This will verify:
+- ✅ Directory structure
+- ✅ Hook configuration
+- ✅ Database accessibility
+- ✅ MCP server integration
+
+### 3. Test memory storage
+Start Claude Code and have a brief conversation. Then check:
+```powershell
+claude-mem status
+```
+
+You should see memory counts increase.
+
+### 4. Search memories
+In Claude Code, ask:
+```
+Search my memories for [your topic]
+```
+
+Claude should use the `mcp__claude-mem__chroma_query_documents` tool automatically.
+
+## Known Issues & Limitations
+
+### ⚠️ PowerShell Profile Creation
+- **Issue**: PowerShell profiles may not exist by default
+- **Impact**: Smart Trash alias installation creates profile directories
+- **Status**: Installer handles this automatically
+
+### ⚠️ Native Module Compilation
+- **Issue**: `better-sqlite3` requires build tools
+- **Impact**: May need Visual Studio Build Tools installed
+- **Workaround**: Installer attempts silent installation; manually rebuild if needed
+
+### ⚠️ Path Case Sensitivity
+- **Issue**: Windows paths are case-insensitive but ChromaDB metadata stores exact case
+- **Impact**: Path comparisons may fail in edge cases
+- **Status**: Generally works fine; use consistent casing
+
+## Getting Help
+
+If you encounter Windows-specific issues:
+
+1. **Run diagnostics**:
+   ```powershell
+   claude-mem doctor
+   ```
+
+2. **Check logs**:
+   ```powershell
+   claude-mem logs
+   ```
+   Or view directly:
+   ```powershell
+   type $env:USERPROFILE\.claude-mem\logs\*.log
+   ```
+
+3. **Verify hook execution**:
+   Check Claude Code's hook output for errors during session start/stop
+
+4. **Report issues**:
+   - Include `claude-mem doctor` output
+   - Include relevant logs
+   - Specify Windows version and PowerShell version
+   - File at: https://github.com/thedotmack/claude-mem/issues
+
+## Development on Windows
+
+If you're developing claude-mem on Windows:
+
+### Prerequisites
+- Install Bun (Windows support is experimental): https://bun.sh/
+- Install Git for Windows
+- Install Visual Studio Build Tools for native modules
+
+### Build Commands
+```powershell
+# Install dependencies
+npm install
+
+# Build minified bundle
+npm run build
+
+# Link for local testing
+bun link
+
+# Reinstall with latest build
+claude-mem install --force
+```
+
+**Note**: Some npm scripts use Unix-style paths and may not work on Windows. Core development is recommended on Unix/macOS systems.
+
+## Summary
+
+✅ **Works on Windows**:
+- Memory capture via streaming hooks
+- ChromaDB semantic search
+- SQLite metadata storage
+- MCP server integration
+- All CLI commands
+- Smart Trash™ system
+- Automatic context loading
+
+⚠️ **May Require Extra Setup**:
+- PowerShell execution policy
+- Visual Studio Build Tools for native modules
+- Manual PATH configuration
+
+The core claude-mem functionality is fully operational on Windows, with the memory capture, storage, and retrieval systems working identically to Unix/macOS.

+- 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" \\

+  --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

+## 🧠 Memory System Quick Reference
+
+### Search Your Memories (SIMPLE & POWERFUL)
+- **Semantic search is king**: \`mcp__claude-mem__chroma_query_documents(["search terms"])\`
+- **🔒 ALWAYS include project name in query**: \`["claude-mem feature authentication"]\` not just \`["feature authentication"]\`
+- **Include dates for temporal search**: \`["project-name 2025-09-09 bug fix"]\` finds memories from that date
+- **Get specific memory**: \`mcp__claude-mem__chroma_get_documents(ids: ["document_id"])\`
+
+### Search Tips That Actually Work
+- **Project isolation**: Always prefix queries with project name to avoid cross-contamination
+- **Temporal search**: Include dates (YYYY-MM-DD) in query text to find memories from specific times
+- **Intent-based**: "implementing oauth" > "oauth implementation code function"
+- **Multiple queries**: Search with different phrasings for better coverage
+- **Session-specific**: Include session ID in query when you know it
+
+### What Doesn't Work (Don't Do This!)
+- ❌ Complex where filters with $and/$or - they cause errors
+- ❌ Timestamp comparisons ($gte/$lt) - Chroma stores timestamps as strings
+- ❌ Mixing project filters in where clause - causes "Error finding id"
+
+### Storage
+- Collection: "claude_memories"
+- Archives: ~/.claude-mem/archives/

+# Hook Prompts System
+
+This directory contains the centralized prompt configuration for all streaming hooks.
+
+## Quick Edit Guide
+
+**Want to change hook prompts?** Edit this file:
+```
+hook-prompts.config.ts
+```
+
+Then rebuild and reinstall:
+```bash
+bun run build
+bun run dev:install
+```
+
+## Files in This Directory
+
+### hook-prompts.config.ts
+**EDIT THIS FILE** to change prompt content.
+
+Contains:
+- `SYSTEM_PROMPT` - Initial instructions for SDK (190 lines)
+- `TOOL_MESSAGE` - Format for tool responses (10 lines)
+- `END_MESSAGE` - Session completion request (10 lines)
+- `HOOK_CONFIG` - Shared settings (truncation limits, SDK options)
+
+Uses `{{variableName}}` template syntax.
+
+### hook-prompt-renderer.ts
+**DON'T EDIT** unless adding new variables or changing rendering logic.
+
+Contains:
+- `renderSystemPrompt()` - Processes system prompt template
+- `renderToolMessage()` - Processes tool message template
+- `renderEndMessage()` - Processes end message template
+- Template substitution and auto-truncation logic
+
+### templates/context/ContextTemplates.ts
+Session start message formatting (separate from hook prompts).
+
+## Template Variables Reference
+
+### SYSTEM_PROMPT Variables
+```typescript
+{
+  project: string;        // Project name (e.g., "claude-mem-source")
+  sessionId: string;      // Claude Code session ID
+  date: string;           // YYYY-MM-DD format
+  userPrompt: string;     // Auto-truncated to 200 chars
+}
+```
+
+### TOOL_MESSAGE Variables
+```typescript
+{
+  toolName: string;       // Tool name (e.g., "Read", "Bash")
+  toolResponse: string;   // Auto-truncated to 20000 chars
+  userPrompt: string;     // Auto-truncated to 200 chars
+  timestamp: string;      // Full ISO timestamp
+  timeFormatted: string;  // HH:MM:SS format (auto-generated)
+}
+```
+
+### END_MESSAGE Variables
+```typescript
+{
+  project: string;        // Project name
+  sessionId: string;      // Claude Code session ID
+}
+```
+
+## Usage in Hooks
+
+### user-prompt-submit-streaming.js
+```javascript
+import { renderSystemPrompt, HOOK_CONFIG } from '../src/prompts/hook-prompt-renderer.js';
+
+const prompt = renderSystemPrompt({
+  project,
+  sessionId: session_id,
+  date,
+  userPrompt: prompt || ''
+});
+
+query({
+  prompt,
+  options: {
+    model: HOOK_CONFIG.sdk.model,
+    allowedTools: HOOK_CONFIG.sdk.allowedTools,
+    maxTokens: HOOK_CONFIG.sdk.maxTokensSystem
+  }
+});
+```
+
+### post-tool-use-streaming.js
+```javascript
+import { renderToolMessage, HOOK_CONFIG } from '../src/prompts/hook-prompt-renderer.js';
+
+const message = renderToolMessage({
+  toolName: tool_name,
+  toolResponse: toolResponseStr,
+  userPrompt: prompt || '',
+  timestamp: timestamp || new Date().toISOString()
+});
+
+query({
+  prompt: message,
+  options: {
+    model: HOOK_CONFIG.sdk.model,
+    maxTokens: HOOK_CONFIG.sdk.maxTokensTool
+  }
+});
+```
+
+### stop-streaming.js
+```javascript
+import { renderEndMessage, HOOK_CONFIG } from '../src/prompts/hook-prompt-renderer.js';
+
+const message = renderEndMessage({
+  project,
+  sessionId: claudeSessionId
+});
+
+query({
+  prompt: message,
+  options: {
+    model: HOOK_CONFIG.sdk.model,
+    maxTokens: HOOK_CONFIG.sdk.maxTokensEnd
+  }
+});
+```
+
+## Configuration Options
+
+Edit `HOOK_CONFIG` in `hook-prompts.config.ts`:
+
+```typescript
+export const HOOK_CONFIG = {
+  // Truncation limits for template variables
+  maxUserPromptLength: 200,      // Increase to show more context
+  maxToolResponseLength: 20000,  // Increase for larger outputs
+
+  // SDK configuration
+  sdk: {
+    model: 'claude-sonnet-4-5',  // Change model version
+    allowedTools: ['Bash'],      // Add more tools if needed
+    maxTokensSystem: 8192,       // Token limit for system prompt
+    maxTokensTool: 8192,         // Token limit for tool messages
+    maxTokensEnd: 2048,          // Token limit for end message
+  },
+};
+```
+
+## Example: Editing a Prompt
+
+### Before
+```typescript
+export const TOOL_MESSAGE = `# Tool Response {{timeFormatted}}
+
+Tool: {{toolName}}
+User Context: "{{userPrompt}}"
+
+\`\`\`
+{{toolResponse}}
+\`\`\`
+
+Analyze and store if meaningful.`;
+```
+
+### After
+```typescript
+export const TOOL_MESSAGE = `# Analysis Request {{timeFormatted}}
+
+Executed: {{toolName}}
+Context: "{{userPrompt}}"
+Priority: High
+
+Output:
+\`\`\`
+{{toolResponse}}
+\`\`\`
+
+IMPORTANT: Only store if this contains:
+- New code patterns or logic
+- Architecture decisions
+- Error messages with solutions
+- Configuration changes
+
+Skip trivial operations.`;
+```
+
+### Apply Changes
+```bash
+bun run build && bun run dev:install
+```
+
+## Benefits
+
+### DRY Compliance
+- **Before**: 3 files with 188 lines of hardcoded prompts
+- **After**: 1 config file with all prompts centralized
+
+### Maintainability
+- Change prompts without touching hook implementation
+- Type-safe template variables
+- Consistent formatting across all hooks
+- Version-controlled prompt history
+
+### Flexibility
+- Easy A/B testing of different instructions
+- Simple to adjust truncation limits
+- Quick model/token configuration changes
+- Template variables prevent copy-paste errors
+
+## Full Documentation
+
+See `/Users/alexnewman/Scripts/claude-mem-source/docs/HOOK_PROMPTS.md` for:
+- Detailed editing guide
+- Troubleshooting common issues
+- Adding new template variables

+- 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)
