+- Used by developers working on claude-mem
+- Not included in the plugin distribution
+- Project-specific workflows (version bumps, release management, etc.)
+- Not synced to `~/.claude/plugins/marketplaces/thedotmack/`

 # Version Bump Skill
 
-IMPORTANT: This skill manages semantic versioning across the claude-mem project. YOU MUST update all FOUR version-tracked files consistently and create a git tag.
+Manage semantic versioning across the claude-mem project with consistent updates to all version-tracked files.
 
 ## Quick Reference
 
-**Files requiring updates:**
+**Files requiring updates (ALL FOUR):**
 1. `package.json` (line 3)
 2. `.claude-plugin/marketplace.json` (line 13)
 3. `plugin/.claude-plugin/plugin.json` (line 3)
 4. `CLAUDE.md` (line 9 ONLY - version number, NOT version history)
 
 **Semantic versioning:**
-- PATCH (x.y.Z): Bugfixes only
-- MINOR (x.Y.0): New features, backward compatible
-- MAJOR (X.0.0): Breaking changes
+- **PATCH** (x.y.Z): Bugfixes only
+- **MINOR** (x.Y.0): New features, backward compatible
+- **MAJOR** (X.0.0): Breaking changes
 
-## Workflow
+## Quick Decision Guide
 
-When invoked, follow this process:
+**What changed?**
+- "Fixed a bug" → PATCH (5.3.0 → 5.3.1)
+- "Added new feature" → MINOR (5.3.0 → 5.4.0)
+- "Breaking change" → MAJOR (5.3.0 → 6.0.0)
 
-### 1. Analyze Changes
-First, understand what changed:
-```bash
-git log --oneline -5
-git diff HEAD~1
-```
+**If unclear, ASK THE USER explicitly.**
 
-### 2. Determine Version Type
-Ask yourself:
-- Breaking changes? → MAJOR
-- New features? → MINOR
-- Bugfixes only? → PATCH
+## Standard Workflow
 
-If unclear, ASK THE USER explicitly.
+See [operations/workflow.md](operations/workflow.md) for detailed step-by-step process.
 
-### 3. Calculate New Version
-From current version in `package.json`:
-```bash
-grep '"version"' package.json
-```
-
-Apply semantic versioning rules:
-- Patch: increment Z (4.2.8 → 4.2.9)
-- Minor: increment Y, reset Z (4.2.8 → 4.3.0)
-- Major: increment X, reset Y and Z (4.2.8 → 5.0.0)
-
-### 4. Preview Changes
-BEFORE making changes, show the user:
-```
-Current version: 4.2.8
-New version: 4.2.9 (PATCH)
-Reason: Fixed database query bug
-
-Files to update:
-- package.json: "version": "4.2.9"
-- marketplace.json: "version": "4.2.9"
-- plugin.json: "version": "4.2.9"
-- CLAUDE.md line 9: "**Current Version**: 4.2.9" (version number ONLY)
-- Git tag: v4.2.9
-
-Proceed? (yes/no)
-```
-
-### 5. Update Files
-
-**Update package.json:**
-```json
-{
-  "name": "claude-mem",
-  "version": "4.2.9",
-  ...
-}
-```
-
-**Update .claude-plugin/marketplace.json:**
-```json
-{
-  "name": "claude-mem",
-  "version": "4.2.9",
-  ...
-}
-```
-
-**Update plugin/.claude-plugin/plugin.json:**
-```json
-{
-  "name": "claude-mem",
-  "version": "4.2.9",
-  ...
-}
-```
-
-**Update CLAUDE.md:**
-ONLY update line 9 with the version number:
-```markdown
-**Current Version**: 4.2.9
-```
-
-**CRITICAL**: DO NOT add version history entries to CLAUDE.md. Version history is managed separately outside this skill.
-
-### 6. Verify Consistency
-```bash
-# Check all versions match
-grep -n '"version"' package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json
-# Should show same version in all three files
-```
-
-### 7. Test
-```bash
-# Verify the plugin loads correctly
-npm run build
-```
-
-### 8. Commit and Tag
-```bash
-# Stage all version files
-git add package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json CLAUDE.md plugin/scripts/
-
-# Commit with descriptive message
-git commit -m "Release vX.Y.Z: [Brief description]"
-
-# Create annotated git tag
-git tag vX.Y.Z -m "Release vX.Y.Z: [Brief description]"
-
-# Push commit and tags
-git push && git push --tags
-```
-
-### 9. Create GitHub Release
-```bash
-# Create GitHub release from the tag
-gh release create vX.Y.Z --title "vX.Y.Z" --notes "[Brief release notes]"
-
-# Or generate notes automatically from commits
-gh release create vX.Y.Z --title "vX.Y.Z" --generate-notes
-```
-
-**IMPORTANT**: Always create the GitHub release immediately after pushing the tag. This makes the release discoverable to users and triggers any automated workflows.
+**Quick version:**
+1. Determine version type (PATCH/MINOR/MAJOR)
+2. Calculate new version from current
+3. Preview changes to user
+4. Update ALL FOUR files
+5. Verify consistency
+6. Build and test
+7. Commit and create git tag
+8. Push and create GitHub release
 
 ## Common Scenarios
 
-**Scenario 1: Bug fix after testing**
-```
-User: "Fixed the memory leak in the search function"
-You: Determine → PATCH
-     Calculate → 4.2.8 → 4.2.9
-     Update all four files (version numbers only)
-     Build and commit
-     Create git tag v4.2.9
-     Push commit and tags
-     Create GitHub release v4.2.9
-```
+See [operations/scenarios.md](operations/scenarios.md) for examples:
+- Bug fix releases
+- New feature releases
+- Breaking change releases
 
-**Scenario 2: New MCP tool added**
-```
-User: "Added web search MCP integration"
-You: Determine → MINOR (new feature)
-     Calculate → 4.2.8 → 4.3.0
-     Update all four files (version numbers only)
-     Build and commit
-     Create git tag v4.3.0
-     Push commit and tags
-     Create GitHub release v4.3.0
-```
+## Critical Rules
 
-**Scenario 3: Database schema redesign**
-```
-User: "Rewrote storage layer, old data needs migration"
-You: Determine → MAJOR (breaking change)
-     Calculate → 4.2.8 → 5.0.0
-     Update all four files (version numbers only)
-     Build and commit
-     Create git tag v5.0.0
-     Push commit and tags
-     Create GitHub release v5.0.0
-```
-
-## Error Prevention
-
-**ALWAYS verify:**
-- [ ] All FOUR files have matching version numbers (package.json, marketplace.json, plugin.json, CLAUDE.md)
-- [ ] Git tag created with format vX.Y.Z
-- [ ] GitHub release created from the tag
-- [ ] CLAUDE.md: ONLY updated line 9 (version number), did NOT touch version history
-- [ ] Commit and tags pushed to remote
+**ALWAYS:**
+- Update ALL FOUR files with matching version numbers
+- Create git tag with format `vX.Y.Z`
+- Create GitHub release from the tag
+- Ask user if version type is unclear
 
 **NEVER:**
-- Update only one, two, or three files - ALL FOUR must be updated
+- Update only one, two, or three files
 - Skip the verification step
-- Forget to create git tag
-- Forget to create GitHub release
-- Forget to ask user if version type is unclear
+- Forget to create git tag or GitHub release
 - Add version history entries to CLAUDE.md (that's managed separately)
 
+## Verification Checklist
+
+Before considering the task complete:
+- [ ] All FOUR files have matching version numbers
+- [ ] `npm run build` succeeds
+- [ ] Git commit created with all version files
+- [ ] Git tag created (format: vX.Y.Z)
+- [ ] Commit and tags pushed to remote
+- [ ] GitHub release created from the tag
+- [ ] CLAUDE.md: ONLY line 9 updated (version number), NOT version history
+

+```
+
+## Semantic Versioning Rules
+
+### Version Format: MAJOR.MINOR.PATCH
+
+**MAJOR (X.0.0):**
+- Breaking changes
+- Incompatible API changes
+- Schema changes requiring migration
+- Removes features
+
+**MINOR (x.Y.0):**
+- New features (backward compatible)
+- New functionality
+- Deprecations (but not removals)
+- Resets PATCH to 0
+
+**PATCH (x.y.Z):**
+- Bug fixes
+- Performance improvements
+- Documentation fixes
+- No new features
+
+### Incrementing Rules
+
+```
+PATCH: 5.3.2 → 5.3.3
+MINOR: 5.3.2 → 5.4.0 (resets patch)
+MAJOR: 5.3.2 → 6.0.0 (resets minor and patch)
+```
+
+## Common Patterns
+
+### Bug Fix Release
+
+```bash
+# Example: 5.3.0 → 5.3.1
+# 1. Update all four files to 5.3.1
+# 2. Build and test
+npm run build
+# 3. Commit and tag
+git add package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json CLAUDE.md plugin/scripts/
+git commit -m "Release v5.3.1: Fixed observer crash"
+git tag v5.3.1 -m "Release v5.3.1: Fixed observer crash"
+git push && git push --tags
+# 4. Create release
+gh release create v5.3.1 --title "v5.3.1" --notes "Fixed observer crash on empty content"
+```
+
+### Feature Release
+
+```bash
+# Example: 5.3.0 → 5.4.0
+# 1. Update all four files to 5.4.0
+# 2. Build and test
+npm run build
+# 3. Commit and tag
+git add package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json CLAUDE.md plugin/scripts/
+git commit -m "Release v5.4.0: Added dark mode support"
+git tag v5.4.0 -m "Release v5.4.0: Added dark mode support"
+git push && git push --tags
+# 4. Create release
+gh release create v5.4.0 --title "v5.4.0" --generate-notes
+```
+
+### Breaking Change Release
+
+```bash
+# Example: 5.3.0 → 6.0.0
+# 1. Update all four files to 6.0.0
+# 2. Build and test
+npm run build
+# 3. Commit and tag
+git add package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json CLAUDE.md plugin/scripts/
+git commit -m "Release v6.0.0: Storage layer redesign"
+git tag v6.0.0 -m "Release v6.0.0: Storage layer redesign"
+git push && git push --tags
+# 4. Create release with warning
+gh release create v6.0.0 --title "v6.0.0" --notes "⚠️ Breaking change: Storage layer redesigned. Migration required."
+```
+
+## Rollback Commands
+
+### Delete Tag
+
+```bash
+# Delete local tag
+git tag -d vX.Y.Z
+
+# Delete remote tag
+git push origin :refs/tags/vX.Y.Z
+# Or: git push --delete origin vX.Y.Z
+```
+
+### Delete Release
+
+```bash
+# Delete GitHub release
+gh release delete vX.Y.Z
+
+# Confirm deletion
+gh release delete vX.Y.Z --yes
+```
+
+### Revert Commit
+
+```bash
+# Revert last commit (creates new commit)
+git revert HEAD
+
+# Reset to previous commit (destructive)
+git reset --hard HEAD~1
+git push --force  # Dangerous! Only if not shared
+```
+
+## Error Prevention
+
+### Pre-commit Checks
+
+```bash
+# Check all versions match before committing
+V1=$(grep '"version"' package.json | head -1 | sed 's/.*"\([^"]*\)".*/\1/')
+V2=$(grep '"version"' .claude-plugin/marketplace.json | sed 's/.*"\([^"]*\)".*/\1/')
+V3=$(grep '"version"' plugin/.claude-plugin/plugin.json | head -1 | sed 's/.*"\([^"]*\)".*/\1/')
+
+if [ "$V1" = "$V2" ] && [ "$V2" = "$V3" ]; then
+  echo "✓ All versions match: $V1"
+else
+  echo "✗ Version mismatch!"
+  echo "  package.json: $V1"
+  echo "  marketplace.json: $V2"
+  echo "  plugin.json: $V3"
+fi
+```
+
+### Pre-push Checks
+
+```bash
+# Check tag exists
+git tag -l | grep vX.Y.Z || echo "Warning: Tag not created"
+
+# Check build succeeds
+npm run build || echo "Error: Build failed"
+
+# Check no uncommitted changes
+git status --porcelain | grep -q . && echo "Warning: Uncommitted changes"
+```

+# Common Version Bump Scenarios
+
+Real-world examples of version bumps with decision rationale.
+
+## Scenario 1: Bug Fix After Testing
+
+**User request:**
+> "Fixed the memory leak in the search function"
+
+**Analysis:**
+- What changed: Bug fix
+- Breaking changes: No
+- New features: No
+- **Decision: PATCH**
+
+**Workflow:**
+```
+Current: 4.2.8
+New: 4.2.9 (PATCH)
+
+Steps:
+1. Update all four files to 4.2.9
+2. npm run build
+3. git commit -m "Release v4.2.9: Fixed memory leak in search"
+4. git tag v4.2.9 -m "Release v4.2.9: Fixed memory leak in search"
+5. git push && git push --tags
+6. gh release create v4.2.9 --title "v4.2.9" --notes "Fixed memory leak in search function"
+```
+
+## Scenario 2: New Feature Added
+
+**User request:**
+> "Added web search MCP integration"
+
+**Analysis:**
+- What changed: New feature (MCP integration)
+- Breaking changes: No
+- Backward compatible: Yes
+- **Decision: MINOR**
+
+**Workflow:**
+```
+Current: 4.2.8
+New: 4.3.0 (MINOR - reset patch to 0)
+
+Steps:
+1. Update all four files to 4.3.0
+2. npm run build
+3. git commit -m "Release v4.3.0: Added web search MCP integration"
+4. git tag v4.3.0 -m "Release v4.3.0: Added web search MCP integration"
+5. git push && git push --tags
+6. gh release create v4.3.0 --title "v4.3.0" --generate-notes
+```
+
+## Scenario 3: Database Schema Redesign
+
+**User request:**
+> "Rewrote storage layer, old data needs migration"
+
+**Analysis:**
+- What changed: Storage layer rewrite
+- Breaking changes: Yes (requires migration)
+- Backward compatible: No
+- **Decision: MAJOR**
+
+**Workflow:**
+```
+Current: 4.2.8
+New: 5.0.0 (MAJOR - reset minor and patch to 0)
+
+Steps:
+1. Update all four files to 5.0.0
+2. npm run build
+3. git commit -m "Release v5.0.0: Storage layer redesign with migration required"
+4. git tag v5.0.0 -m "Release v5.0.0: Storage layer redesign"
+5. git push && git push --tags
+6. gh release create v5.0.0 --title "v5.0.0" --notes "⚠️ Breaking change: Storage layer redesigned. Migration required."
+```
+
+## Scenario 4: Multiple Small Bug Fixes
+
+**User request:**
+> "Fixed three bugs: observer crash, viewer pagination, and date formatting"
+
+**Analysis:**
+- What changed: Multiple bug fixes
+- Breaking changes: No
+- New features: No
+- **Decision: PATCH** (one patch covers all fixes)
+
+**Workflow:**
+```
+Current: 4.2.8
+New: 4.2.9 (PATCH)
+
+Steps:
+1. Update all four files to 4.2.9
+2. npm run build
+3. git commit -m "Release v4.2.9: Multiple bug fixes
+
+- Fixed observer crash on empty content
+- Fixed viewer pagination edge case
+- Fixed date formatting in timeline"
+4. git tag v4.2.9 -m "Release v4.2.9: Multiple bug fixes"
+5. git push && git push --tags
+6. gh release create v4.2.9 --title "v4.2.9" --generate-notes
+```
+
+## Scenario 5: Feature + Bug Fix
+
+**User request:**
+> "Added dark mode support and fixed the viewer crash bug"
+
+**Analysis:**
+- What changed: New feature + bug fix
+- Breaking changes: No
+- **Decision: MINOR** (feature trumps bug fix)
+
+**Workflow:**
+```
+Current: 5.1.0
+New: 5.2.0 (MINOR)
+
+Steps:
+1. Update all four files to 5.2.0
+2. npm run build
+3. git commit -m "Release v5.2.0: Dark mode support + bug fixes
+
+Features:
+- Added dark mode toggle to viewer UI
+
+Bug fixes:
+- Fixed viewer crash on empty database"
+4. git tag v5.2.0 -m "Release v5.2.0: Dark mode support"
+5. git push && git push --tags
+6. gh release create v5.2.0 --title "v5.2.0" --generate-notes
+```
+
+## Scenario 6: Documentation Only
+
+**User request:**
+> "Updated README with new installation instructions"
+
+**Analysis:**
+- What changed: Documentation only
+- Breaking changes: No
+- Code changes: No
+- **Decision: PATCH** (or skip version bump if no code changes)
+
+**Workflow:**
+```
+Option 1: PATCH (if you want to tag doc improvements)
+Current: 4.2.8
+New: 4.2.9
+
+Option 2: No version bump (documentation-only changes don't require versioning)
+Just commit without bumping version
+```
+
+**Recommendation:** Skip version bump for documentation-only changes unless it's a significant documentation overhaul.
+
+## Scenario 7: Configuration Change
+
+**User request:**
+> "Changed default observation count from 50 to 30"
+
+**Analysis:**
+- What changed: Default configuration
+- Breaking changes: Yes (behavior changes)
+- Users might notice different context size
+- **Decision: MINOR or MAJOR** (ask user)
+
+**Workflow:**
+```
+Ask user:
+"This changes default behavior (context size). Users will see different results.
+Is this:
+- MINOR (acceptable behavior change): 4.2.8 → 4.3.0
+- MAJOR (breaking change): 4.2.8 → 5.0.0
+
+Which should I use?"
+```
+
+## Scenario 8: Dependency Update
+
+**User request:**
+> "Updated Claude SDK from 1.2.0 to 1.3.0"
+
+**Analysis:**
+- What changed: Dependency version
+- Breaking changes: Depends on SDK changes
+- **Decision: Ask user or check SDK changelog**
+
+**Workflow:**
+```
+1. Check SDK changelog for breaking changes
+2. If SDK has breaking changes → MAJOR
+3. If SDK adds features → MINOR
+4. If SDK only fixes bugs → PATCH
+
+Typical: PATCH (unless SDK breaks compatibility)
+```
+
+## Decision Tree
+
+```
+Is there a breaking change?
+├─ Yes → MAJOR (X.0.0)
+└─ No
+   ├─ Is there a new feature?
+   │  ├─ Yes → MINOR (x.Y.0)
+   │  └─ No
+   │     ├─ Is there a bug fix?
+   │     │  ├─ Yes → PATCH (x.y.Z)
+   │     │  └─ No → Don't bump version (docs only, etc.)
+   │     └─ Configuration change? → Ask user (MINOR or MAJOR)
+   └─ Multiple changes? → Use highest level (MAJOR > MINOR > PATCH)
+```

+Step-by-step process for bumping versions in the claude-mem project.
+
+## Step 1: Analyze Changes
+
+First, understand what changed:
+
+```bash
+# View recent commits
+git log --oneline -5
+
+# See what changed in last commit
+git diff HEAD~1
+
+# Or see all changes since last tag
+LAST_TAG=$(git describe --tags --abbrev=0)
+git log $LAST_TAG..HEAD --oneline
+git diff $LAST_TAG..HEAD
+```
+
+## Step 2: Determine Version Type
+
+Ask yourself:
+- **Breaking changes?** → MAJOR
+- **New features?** → MINOR
+- **Bugfixes only?** → PATCH
+
+**If unclear, ASK THE USER explicitly.**
+
+### Decision Matrix
+
+| Change Type | Version Bump | Example |
+|------------|--------------|---------|
+| Bug fix | PATCH | 4.2.8 → 4.2.9 |
+| New feature (backward compatible) | MINOR | 4.2.8 → 4.3.0 |
+| Breaking change | MAJOR | 4.2.8 → 5.0.0 |
+| Multiple features | MINOR | 4.2.8 → 4.3.0 |
+| Feature + breaking change | MAJOR | 4.2.8 → 5.0.0 |
+
+## Step 3: Calculate New Version
+
+From current version in `package.json`:
+
+```bash
+grep '"version"' package.json
+```
+
+Apply semantic versioning rules:
+- **Patch:** increment Z (4.2.8 → 4.2.9)
+- **Minor:** increment Y, reset Z (4.2.8 → 4.3.0)
+- **Major:** increment X, reset Y and Z (4.2.8 → 5.0.0)
+
+## Step 4: Preview Changes
+
+**BEFORE making changes, show the user:**
+
+```
+Current version: 4.2.8
+New version: 4.2.9 (PATCH)
+Reason: Fixed database query bug
+
+Files to update:
+- package.json: "version": "4.2.9"
+- marketplace.json: "version": "4.2.9"
+- plugin.json: "version": "4.2.9"
+- CLAUDE.md line 9: "**Current Version**: 4.2.9" (version number ONLY)
+- Git tag: v4.2.9
+
+Proceed? (yes/no)
+```
+
+Wait for user confirmation before proceeding.
+
+## Step 5: Update Files
+
+### Update package.json
+
+File: `package.json`
+
+```json
+{
+  "name": "claude-mem",
+  "version": "4.2.9",
+  ...
+}
+```
+
+Update line 3 with new version.
+
+### Update marketplace.json
+
+File: `.claude-plugin/marketplace.json`
+
+```json
+{
+  "name": "claude-mem",
+  "version": "4.2.9",
+  ...
+}
+```
+
+Update line 13 with new version.
+
+### Update plugin.json
+
+File: `plugin/.claude-plugin/plugin.json`
+
+```json
+{
+  "name": "claude-mem",
+  "version": "4.2.9",
+  ...
+}
+```
+
+Update line 3 with new version.
+
+### Update CLAUDE.md
+
+File: `CLAUDE.md`
+
+**ONLY update line 9 with the version number:**
+
+```markdown
+**Current Version**: 4.2.9
+```
+
+**CRITICAL:** DO NOT add version history entries to CLAUDE.md. Version history is managed separately outside this skill.
+
+## Step 6: Verify Consistency
+
+```bash
+# Check all versions match
+grep -n '"version"' package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json
+
+# Should show same version in all three files:
+# package.json:3:  "version": "4.2.9",
+# .claude-plugin/marketplace.json:13:  "version": "4.2.9",
+# plugin/.claude-plugin/plugin.json:3:  "version": "4.2.9",
+```
+
+All three must match exactly.
+
+## Step 7: Test
+
+```bash
+# Verify the plugin loads correctly
+npm run build
+```
+
+Build must succeed before proceeding.
+
+## Step 8: Commit and Tag
+
+```bash
+# Stage all version files
+git add package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json CLAUDE.md plugin/scripts/
+
+# Commit with descriptive message
+git commit -m "Release vX.Y.Z: [Brief description]
+
+[Optional detailed description]
+
+🤖 Generated with [Claude Code](https://claude.com/claude-code)
+
+Co-Authored-By: Claude <noreply@anthropic.com>"
+
+# Create annotated git tag
+git tag vX.Y.Z -m "Release vX.Y.Z: [Brief description]"
+
+# Push commit and tags
+git push && git push --tags
+```
+
+Replace `X.Y.Z` with actual version (e.g., `4.2.9`).
+
+## Step 9: Create GitHub Release
+
+```bash
+# Create GitHub release from the tag
+gh release create vX.Y.Z --title "vX.Y.Z" --notes "[Brief release notes]"
+
+# Or generate notes automatically from commits
+gh release create vX.Y.Z --title "vX.Y.Z" --generate-notes
+```
+
+**IMPORTANT:** Always create the GitHub release immediately after pushing the tag. This makes the release discoverable to users and triggers any automated workflows.
+
+## Verification
+
+After completing all steps, verify:
+
+```bash
+# Check git tag created
+git tag -l | grep vX.Y.Z
+
+# Check remote has tag
+git ls-remote --tags origin | grep vX.Y.Z
+
+# Check GitHub release exists
+gh release view vX.Y.Z
+
+# Verify versions match
+grep '"version"' package.json .claude-plugin/marketplace.json plugin/.claude-plugin/plugin.json
+```
+
+All checks should pass.
+
+## Rollback (If Needed)
+
+If you made a mistake:
+
+```bash
+# Delete local tag
+git tag -d vX.Y.Z
+
+# Delete remote tag (if already pushed)
+git push origin :refs/tags/vX.Y.Z
+
+# Delete GitHub release (if created)
+gh release delete vX.Y.Z
+
+# Revert commits if needed
+git revert HEAD
+```
+
+Then restart the workflow with correct version.

+## [5.4.0] - 2025-11-09
+
+### ⚠️ BREAKING CHANGE: MCP Search Tools Removed
+
+**Migration**: None required. Claude automatically uses the search skill when needed.
+
+### Changed
+- **Skill-Based Search Architecture**: Replaced MCP search tools with skill-based HTTP API
+  - **Token Savings**: ~2,250 tokens per session start

+  - Search functionality works identically but with better efficiency
+  - No user action required - migration is transparent
+
+### Added
+- **10 New HTTP Search API Endpoints** in worker service:
+  - `GET /api/search/observations` - Full-text search observations
+  - `GET /api/search/sessions` - Full-text search session summaries
+  - `GET /api/search/prompts` - Full-text search user prompts
+  - `GET /api/search/by-concept` - Find observations by concept tag
+  - `GET /api/search/by-file` - Find work related to specific files
+  - `GET /api/search/by-type` - Find observations by type (bugfix, feature, etc.)
+  - `GET /api/context/recent` - Get recent session context
+  - `GET /api/context/timeline` - Get timeline around specific point in time
+  - `GET /api/timeline/by-query` - Search + timeline in one call

+# PR Summary: Fix SDK Agent Missing Working Directory Context (CWD)
+
+## Problem
+The SDK agent lacked spatial awareness because working directory (CWD) information was captured at the hook level but deliberately not passed to the worker service. This caused:
+- SDK agent searching wrong repositories
+- False "file not found" reports even when files existed
+- Inability to match user-requested paths to tool execution paths
+- Inaccurate observations due to spatial confusion
+
+## Solution
+Added CWD propagation through the entire data pipeline from hook to SDK agent, enabling spatial awareness.
+
+## Technical Changes
+
+### Data Flow
+```
+PostToolUseInput.cwd → save-hook → Worker API → SessionManager → SDK Agent → Prompt XML
+```
+
+### Files Modified (8 source + 2 build artifacts + 2 docs)
+1. `src/services/worker-types.ts` - Added `cwd?: string` to interfaces
+2. `src/hooks/save-hook.ts` - Extract and pass CWD to worker
+3. `src/services/worker-service.ts` - Accept CWD in observations endpoint
+4. `src/services/worker/SessionManager.ts` - Include CWD in message queue
+5. `src/services/worker/SDKAgent.ts` - Pass CWD to prompt builder
+6. `src/sdk/prompts.ts` - Include `<tool_cwd>` in XML + spatial awareness docs
+7. `tests/cwd-propagation.test.ts` - 8 comprehensive tests (NEW)
+8. `docs/CWD_CONTEXT_FIX.md` - Technical documentation (NEW)
+9. `CHANGELOG.md` - User-facing changelog entry
+
+### Example Output
+Before (no spatial awareness):
+```xml
+<tool_used>
+  <tool_name>ReadTool</tool_name>
+  <tool_time>2025-11-10T19:18:03.065Z</tool_time>
+  <tool_input>{"path":"src/index.ts"}</tool_input>
+  <tool_output>{"content":"..."}</tool_output>
+</tool_used>
+```
+
+After (with spatial awareness):
+```xml
+<tool_used>
+  <tool_name>ReadTool</tool_name>
+  <tool_time>2025-11-10T19:18:03.065Z</tool_time>
+  <tool_cwd>/home/user/awesome-project</tool_cwd>
+  <tool_input>{"path":"src/index.ts"}</tool_input>
+  <tool_output>{"content":"..."}</tool_output>
+</tool_used>
+```
+
+### Init Prompt Enhancement
+Added "SPATIAL AWARENESS" section explaining:
+- Tool executions include working directory (tool_cwd)
+- Which repository/project is being worked on
+- Where files are located relative to project root
+- How to match requested paths to actual execution paths
+
+## Testing
+
+### Unit Tests
+✅ 8 tests in `tests/cwd-propagation.test.ts` - all passing
+- Interface definitions include cwd
+- Hook extracts cwd from input
+- Worker API accepts cwd
+- SessionManager queues cwd
+- SDK Agent passes cwd to prompts
+- Prompt builder includes tool_cwd element
+- End-to-end flow validation
+
+### Build Verification
+✅ All builds successful
+- `plugin/scripts/save-hook.js` includes `cwd:s||""`
+- `plugin/scripts/worker-service.cjs` includes `<tool_cwd>` element
+- `plugin/scripts/worker-service.cjs` includes "SPATIAL AWARENESS" section
+
+### Security Scan
+✅ CodeQL: 0 vulnerabilities
+
+## Benefits
+
+1. **Spatial Awareness**: SDK agent knows which directory/repository it's observing
+2. **Accurate Path Matching**: Can verify if requested paths match executed paths
+3. **Better Observations**: Won't search wrong repositories or report false negatives
+4. **Universal Model Support**: Works with Haiku, Sonnet, and Opus (no premium workaround needed)
+
+## Backward Compatibility
+
+- ✅ `cwd` is optional (`cwd?: string`) - no breaking changes
+- ✅ Missing `cwd` handled gracefully (defaults to empty string)
+- ✅ Existing observations without `cwd` continue to work
+- ✅ No database migration required (CWD is transient, not persisted)
+
+## Evidence from Issue
+
+**Test Case**: User requested "Review and understand ai_docs/continuous-improvement/rules.md"
+
+**Before Fix**:
+1. File exists at `/Users/.../dev/personal/lunar-claude/ai_docs/...` ✅
+2. Read tool successfully read the file ✅
+3. SDK agent received tool executions but **no CWD** ❌
+4. SDK agent searched **claude-mem repository** instead of lunar-claude ❌
+5. Summary reported: "File does not exist" ❌
+
+**After Fix**:
+1. File exists at `/Users/.../dev/personal/lunar-claude/ai_docs/...` ✅
+2. Read tool successfully read the file ✅
+3. SDK agent receives tool executions **with CWD** ✅
+4. SDK agent searches **correct repository (lunar-claude)** ✅
+5. Summary accurate: "Reviewed rules.md in lunar-claude project" ✅
+
+## Validation Checklist
+
+- [x] TypeScript compiles without errors
+- [x] All tests pass (8/8)
+- [x] Build artifacts include CWD propagation
+- [x] No security vulnerabilities
+- [x] Documentation complete
+- [x] Backward compatible
+- [x] Example prompts verified

-Claude-Mem provides 9 specialized search tools:
+Claude-Mem provides intelligent search through a skill that auto-invokes when you ask about past work:
 
-1. **search_observations** - Full-text search across observations
-2. **search_sessions** - Full-text search across session summaries
-3. **search_user_prompts** - Search raw user requests
-4. **find_by_concept** - Find by concept tags (discovery, problem-solution, pattern, etc.)
-5. **find_by_file** - Find observations referencing specific files
-6. **find_by_type** - Find by type (decision, bugfix, feature, refactor, discovery, change)
-7. **get_recent_context** - Get recent session context for a project
-8. **get_context_timeline** - Get unified timeline of context around a specific point in time
-9. **get_timeline_by_query** - Search for observations and get timeline context around best match

+- ✅ Optional field (`cwd?: string`) - missing values default to empty string
+- ✅ No direct file system operations using CWD
+- ✅ CWD is only used for context in prompts (read-only)
+- ✅ No shell command injection risk (not passed to exec/spawn)
+
+### 2. Data Flow Security
+```
+Hook Input → Worker API → SessionManager → SDK Agent → Prompt Text
+```
+
+- ✅ CWD passed through JSON serialization (escaped)
+- ✅ No SQL injection risk (not stored in database)
+- ✅ No XSS risk (used in backend prompts, not web UI)
+- ✅ No path traversal risk (not used for file operations)
+
+### 3. Prompt Injection Considerations
+The CWD is included in XML prompts sent to the SDK agent:
+```xml
+<tool_cwd>/home/user/project</tool_cwd>
+```
+
+**Risk Assessment**: LOW
+- CWD comes from Claude Code runtime (trusted source)
+- Claude Code validates and sanitizes session context
+- SDK agent operates in isolated subprocess
+- No user-controlled prompt injection vector
+
+### 4. Backward Compatibility
+- ✅ Optional field - no breaking changes
+- ✅ Graceful degradation when CWD missing
+- ✅ No changes to existing security boundaries
+- ✅ No new external dependencies
+
+## Security Best Practices Applied
+
+1. **Defense in Depth**: CWD is display-only context, not used for authorization
+2. **Least Privilege**: No elevated permissions required
+3. **Input Validation**: Type-safe interfaces with optional fields
+4. **Safe Defaults**: Missing CWD defaults to empty string (safe)
+5. **Immutability**: CWD is read-only once extracted from hook input
+
+## Potential Future Considerations
+
+While the current implementation is secure, future enhancements should consider:
+
+1. **Path Sanitization**: If CWD is ever used for file operations, implement strict path validation
+2. **Length Limits**: Consider max length for CWD field to prevent buffer issues
+3. **Allowlist**: If needed, implement allowlist of permitted directories
+4. **Audit Logging**: Log CWD values for security monitoring (if required)
+
+## Conclusion
+
+✅ **No security vulnerabilities identified**
+✅ **Implementation follows security best practices**
+✅ **Ready for production deployment**
+
+The CWD context fix introduces no new security risks and maintains the existing security posture of the claude-mem plugin.

+# CWD Context Fix - Technical Documentation
+
+## Overview
+
+This fix adds working directory (CWD) context propagation through the entire claude-mem pipeline, enabling the SDK agent to have spatial awareness of which directory/repository it's observing.
+
+## Problem Statement
+
+Previously, the SDK agent would:
+- Search wrong repositories when analyzing file operations
+- Report "file not found" for files that actually exist
+- Lack context about which project was being worked on
+- Generate inaccurate observations due to spatial confusion
+
+## Solution
+
+The CWD information now flows through the entire system:
+
+```
+Hook Input (cwd) → Worker API (cwd) → SessionManager (cwd) → SDK Agent (tool_cwd)
+```
+
+## Data Flow
+
+### 1. Hook Layer (`save-hook.ts`)
+```typescript
+export interface PostToolUseInput {
+  session_id: string;
+  cwd: string;  // ← Captured from Claude Code
+  tool_name: string;
+  tool_input: any;
+  tool_response: any;
+}
+```
+
+The hook extracts `cwd` and includes it in the worker API request:
+```typescript
+body: JSON.stringify({
+  tool_name,
+  tool_input,
+  tool_response,
+  prompt_number,
+  cwd: cwd || ''  // ← Passed to worker
+})
+```
+
+### 2. Worker Service (`worker-service.ts`)
+```typescript
+const { tool_name, tool_input, tool_response, prompt_number, cwd } = req.body;
+
+this.sessionManager.queueObservation(sessionDbId, {
+  tool_name,
+  tool_input,
+  tool_response,
+  prompt_number,
+  cwd  // ← Forwarded to queue
+});
+```
+
+### 3. Session Manager (`SessionManager.ts`)
+```typescript
+session.pendingMessages.push({
+  type: 'observation',
+  tool_name: data.tool_name,
+  tool_input: data.tool_input,
+  tool_response: data.tool_response,
+  prompt_number: data.prompt_number,
+  cwd: data.cwd  // ← Included in message queue
+});
+```
+
+### 4. SDK Agent (`SDKAgent.ts`)
+```typescript
+content: buildObservationPrompt({
+  id: 0,
+  tool_name: message.tool_name!,
+  tool_input: JSON.stringify(message.tool_input),
+  tool_output: JSON.stringify(message.tool_response),
+  created_at_epoch: Date.now(),
+  cwd: message.cwd  // ← Passed to prompt builder
+})
+```
+
+### 5. Prompt Generation (`prompts.ts`)
+```typescript
+return `<tool_used>
+  <tool_name>${obs.tool_name}</tool_name>
+  <tool_time>${new Date(obs.created_at_epoch).toISOString()}</tool_time>${obs.cwd ? `
+  <tool_cwd>${obs.cwd}</tool_cwd>` : ''}  // ← Included in XML
+  <tool_input>${JSON.stringify(toolInput, null, 2)}</tool_input>
+  <tool_output>${JSON.stringify(toolOutput, null, 2)}</tool_output>
+</tool_used>`;
+```
+
+## SDK Agent Prompt Changes
+
+The init prompt now includes a "SPATIAL AWARENESS" section:
+
+```
+SPATIAL AWARENESS: Tool executions include the working directory (tool_cwd) to help you understand:
+- Which repository/project is being worked on
+- Where files are located relative to the project root
+- How to match requested paths to actual execution paths
+```
+
+## Example Usage
+
+When a user executes a read operation in `/home/user/my-project`:
+
+```xml
+<tool_used>
+  <tool_name>ReadTool</tool_name>
+  <tool_time>2025-11-10T19:18:03.065Z</tool_time>
+  <tool_cwd>/home/user/my-project</tool_cwd>
+  <tool_input>
+  {
+    "path": "src/index.ts"
+  }
+  </tool_input>
+  <tool_output>
+  {
+    "content": "export default..."
+  }
+  </tool_output>
+</tool_used>
+```
+
+The SDK agent now knows:
+1. The operation happened in `/home/user/my-project`
+2. The file `src/index.ts` is relative to that directory
+3. Which repository context to search when generating observations
+
+## Testing
+
+8 comprehensive tests validate the CWD propagation:
+
+```bash
+npx tsx --test tests/cwd-propagation.test.ts
+```
+
+All tests verify:
+- Type interfaces include `cwd` fields
+- Hook extracts and passes `cwd`
+- Worker accepts and forwards `cwd`
+- SDK agent includes `cwd` in prompts
+- End-to-end flow is correct
+
+## Benefits
+
+1. **Spatial Awareness**: SDK agent knows which directory/repository it's observing
+2. **Accurate Path Matching**: Can verify if requested paths match executed paths
+3. **Better Summaries**: Won't search wrong repositories or report false negatives
+4. **Works with All Models**: Even Haiku benefits from correct context (no need for Opus workaround)
+
+## Backward Compatibility
+
+- `cwd` is optional in all interfaces (`cwd?: string`)
+- Missing `cwd` values are handled gracefully (defaults to empty string)
+- Existing observations without `cwd` continue to work
+- No database migration required (CWD is transient, not persisted)
+

+ Plan: Migrate to Skill-Based Search (Deprecate MCP)
+
+ Goal
+
+ Replace MCP search tools with a skill-based approach, reducing session
+ start context from ~2,500 tokens to ~250 tokens. Clean migration, no
+ toggles.
+
+ Implementation Steps
+
+ 1. Add HTTP API Endpoints to Worker Service
+
+ File: src/services/worker-service.ts
+
+ Add 10 new routes that wrap existing SessionSearch methods:
+ - GET /api/search/observations?query=...&format=index&limit=20&project=...
+ - GET /api/search/sessions?query=...&format=index&limit=20
+ - GET /api/search/prompts?query=...&format=index&limit=20
+ - GET /api/search/by-concept?concept=discovery&format=index&limit=5
+ - GET /api/search/by-file?filePath=...&format=index&limit=10
+ - GET /api/search/by-type?type=bugfix&format=index&limit=10
+ - GET /api/context/recent?project=...&limit=3
+ - GET /api/context/timeline?anchor=123&depth_before=10&depth_after=10
+ - GET 
+ /api/timeline/by-query?query=...&mode=auto&depth_before=10&depth_after=10
+ - GET /api/search/help - Returns available endpoints and usage docs
+
+ All endpoints return JSON. Skill parses and formats for readability.
+
+ 2. Create Search Skill
+
+ File: plugin/skills/search/SKILL.md
+
+ Frontmatter:
+ ---
+ name: search
+ description: Search claude-mem persistent memory for past sessions,
+ observations, bugs fixed, features implemented, decisions made, code
+ changes, and previous work. Use when answering questions about history,
+ finding past decisions, or researching previous implementations.
+ ---
+
+ Content: Instructions for all 9 search types using curl to call HTTP
+ endpoints, formatting guidelines, common workflows.
+
+ 3. Remove MCP Search Server
+
+ Files to modify:
+ - Remove plugin/.mcp.json entry for claude-mem-search
+ - Keep src/servers/search-server.ts for reference but don't build it
+ - Update scripts/build-plugin.js to skip building search-server.mjs
+ - Archive search-server implementation (don't delete, for reference)
+
+ 4. Update Documentation
+
+ File: CLAUDE.md
+
+ Remove MCP search references, add skill search explanation:
+ - Token savings: ~2,250 tokens per session
+ - How skill auto-invokes (model-driven, not user-driven)
+ - Available search operations
+ - Examples of triggering searches
+
+ 5. Add Migration Notice
+
+ File: CHANGELOG.md or release notes
+
+ Document the breaking change:
+ ## v5.4.0 - Skill-Based Search Migration
+
+ **BREAKING CHANGE**: MCP search tools have been replaced with a
+ skill-based approach.
+
+ **What changed**:
+ - Removed 9 MCP search tools (search_observations, search_sessions, etc.)
+ - Added `search` skill that provides the same functionality
+ - Reduced session start context by ~2,250 tokens
+
+ **Migration**: None required. Claude automatically uses the search skill
+ when needed.
+ The skill provides the same search capabilities with better token
+ efficiency.
+
+ **Why**: Skill-based search uses progressive disclosure (~250 tokens for
+ frontmatter)
+ instead of loading all 9 tool definitions (~2,500 tokens) on every session
+  start.
+
+ 6. Testing Checklist
+
+ - All 10 HTTP endpoints return correct data
+ - Skill auto-invokes when asking about past work
+ - Skill successfully calls endpoints via curl
+ - Skill formats results as readable markdown
+ - Worker restart updates endpoints
+ - Skill distributed correctly with plugin
+ - No MCP search server registered
+ - Session start context reduced by ~2,250 tokens
+
+ Token Impact
+
+ - Before: ~2,500 tokens (9 MCP tool definitions)
+ - After: ~250 tokens (skill frontmatter only)
+ - Savings: ~2,250 tokens per session start
+
+ User Experience
+
+ New behavior:
+ - User: "What bug did we fix last session?"
+ - Claude sees skill description matches → invokes search skill
+ - Skill loads full instructions → uses curl to call HTTP API → formats
+ results
+ - User sees formatted answer
+
+ No user action required: Migration is transparent, searches work
+ automatically.
+
+ Build & Deploy
+
+ npm run build                # Builds skill, skips MCP server
+ npm run sync-marketplace     # Syncs plugin with skill
+ npm run worker:restart       # Restart worker with new HTTP endpoints
+
+ Rollout
+
+ 1. Ship as breaking change in v5.4.0
+ 2. Update plugin marketplace listing
+ 3. All users get automatic token savings on update
+ 4. Archive MCP search implementation for reference

+# Agent Skills in the SDK
+
+> Extend Claude with specialized capabilities using Agent Skills in the Claude Agent SDK
+
+## Overview
+
+Agent Skills extend Claude with specialized capabilities that Claude autonomously invokes when relevant. Skills are packaged as `SKILL.md` files containing instructions, descriptions, and optional supporting resources.
+
+For comprehensive information about Skills, including benefits, architecture, and authoring guidelines, see the [Agent Skills overview](/en/docs/agents-and-tools/agent-skills/overview).
+
+## How Skills Work with the SDK
+
+When using the Claude Agent SDK, Skills are:
+
+1. **Defined as filesystem artifacts**: Created as `SKILL.md` files in specific directories (`.claude/skills/`)
+2. **Loaded from filesystem**: Skills are loaded from configured filesystem locations. You must specify `settingSources` (TypeScript) or `setting_sources` (Python) to load Skills from the filesystem
+3. **Automatically discovered**: Once filesystem settings are loaded, Skill metadata is discovered at startup from user and project directories; full content loaded when triggered
+4. **Model-invoked**: Claude autonomously chooses when to use them based on context
+5. **Enabled via allowed\_tools**: Add `"Skill"` to your `allowed_tools` to enable Skills
+
+Unlike subagents (which can be defined programmatically), Skills must be created as filesystem artifacts. The SDK does not provide a programmatic API for registering Skills.
+
+<Note>
+  **Default behavior**: By default, the SDK does not load any filesystem settings. To use Skills, you must explicitly configure `settingSources: ['user', 'project']` (TypeScript) or `setting_sources=["user", "project"]` (Python) in your options.
+</Note>
+
+## Using Skills with the SDK
+
+To use Skills with the SDK, you need to:
+
+1. Include `"Skill"` in your `allowed_tools` configuration
+2. Configure `settingSources`/`setting_sources` to load Skills from the filesystem
+
+Once configured, Claude automatically discovers Skills from the specified directories and invokes them when relevant to the user's request.
+
+<CodeGroup>
+  ```python Python theme={null}
+  import asyncio
+  from claude_agent_sdk import query, ClaudeAgentOptions
+
+  async def main():
+      options = ClaudeAgentOptions(
+          cwd="/path/to/project",  # Project with .claude/skills/
+          setting_sources=["user", "project"],  # Load Skills from filesystem
+          allowed_tools=["Skill", "Read", "Write", "Bash"]  # Enable Skill tool
+      )
+
+      async for message in query(
+          prompt="Help me process this PDF document",
+          options=options
+      ):
+          print(message)
+
+  asyncio.run(main())
+  ```
+
+  ```typescript TypeScript theme={null}
+  import { query } from "@anthropic-ai/claude-agent-sdk";
+
+  for await (const message of query({
+    prompt: "Help me process this PDF document",
+    options: {
+      cwd: "/path/to/project",  // Project with .claude/skills/
+      settingSources: ["user", "project"],  // Load Skills from filesystem
+      allowedTools: ["Skill", "Read", "Write", "Bash"]  // Enable Skill tool
+    }
+  })) {
+    console.log(message);
+  }
+  ```
+</CodeGroup>
+
+## Skill Locations
+
+Skills are loaded from filesystem directories based on your `settingSources`/`setting_sources` configuration:
+
+* **Project Skills** (`.claude/skills/`): Shared with your team via git - loaded when `setting_sources` includes `"project"`
+* **User Skills** (`~/.claude/skills/`): Personal Skills across all projects - loaded when `setting_sources` includes `"user"`
+* **Plugin Skills**: Bundled with installed Claude Code plugins
+
+## Creating Skills
+
+Skills are defined as directories containing a `SKILL.md` file with YAML frontmatter and Markdown content. The `description` field determines when Claude invokes your Skill.
+
+**Example directory structure**:
+
+```bash  theme={null}
+.claude/skills/processing-pdfs/
+└── SKILL.md
+```
+
+For complete guidance on creating Skills, including SKILL.md structure, multi-file Skills, and examples, see:
+
+* [Agent Skills in Claude Code](https://code.claude.com/docs/skills): Complete guide with examples
+* [Agent Skills Best Practices](/en/docs/agents-and-tools/agent-skills/best-practices): Authoring guidelines and naming conventions
+
+## Tool Restrictions
+
+<Note>
+  The `allowed-tools` frontmatter field in SKILL.md is only supported when using Claude Code CLI directly. **It does not apply when using Skills through the SDK**.
+
+  When using the SDK, control tool access through the main `allowedTools` option in your query configuration.
+</Note>
+
+To restrict tools for Skills in SDK applications, use the `allowedTools` option:
+
+<Note>
+  Import statements from the first example are assumed in the following code snippets.
+</Note>
+
+<CodeGroup>
+  ```python Python theme={null}
+  options = ClaudeAgentOptions(
+      setting_sources=["user", "project"],  # Load Skills from filesystem
+      allowed_tools=["Skill", "Read", "Grep", "Glob"]  # Restricted toolset
+  )
+
+  async for message in query(
+      prompt="Analyze the codebase structure",
+      options=options
+  ):
+      print(message)
+  ```
+
+  ```typescript TypeScript theme={null}
+  // Skills can only use Read, Grep, and Glob tools
+  for await (const message of query({
+    prompt: "Analyze the codebase structure",
+    options: {
+      settingSources: ["user", "project"],  // Load Skills from filesystem
+      allowedTools: ["Skill", "Read", "Grep", "Glob"]  // Restricted toolset
+    }
+  })) {
+    console.log(message);
+  }
+  ```
+</CodeGroup>
+
+## Discovering Available Skills
+
+To see which Skills are available in your SDK application, simply ask Claude:
+
+<CodeGroup>
+  ```python Python theme={null}
+  options = ClaudeAgentOptions(
+      setting_sources=["user", "project"],  # Load Skills from filesystem
+      allowed_tools=["Skill"]
+  )
+
+  async for message in query(
+      prompt="What Skills are available?",
+      options=options
+  ):
+      print(message)
+  ```
+
+  ```typescript TypeScript theme={null}
+  for await (const message of query({
+    prompt: "What Skills are available?",
+    options: {
+      settingSources: ["user", "project"],  // Load Skills from filesystem
+      allowedTools: ["Skill"]
+    }
+  })) {
+    console.log(message);
+  }
+  ```
+</CodeGroup>
+
+Claude will list the available Skills based on your current working directory and installed plugins.
+
+## Testing Skills
+
+Test Skills by asking questions that match their descriptions:
+
+<CodeGroup>
+  ```python Python theme={null}
+  options = ClaudeAgentOptions(
+      cwd="/path/to/project",
+      setting_sources=["user", "project"],  # Load Skills from filesystem
+      allowed_tools=["Skill", "Read", "Bash"]
+  )
+
+  async for message in query(
+      prompt="Extract text from invoice.pdf",
+      options=options
+  ):
+      print(message)
+  ```
+
+  ```typescript TypeScript theme={null}
+  for await (const message of query({
+    prompt: "Extract text from invoice.pdf",
+    options: {
+      cwd: "/path/to/project",
+      settingSources: ["user", "project"],  // Load Skills from filesystem
+      allowedTools: ["Skill", "Read", "Bash"]
+    }
+  })) {
+    console.log(message);
+  }
+  ```
+</CodeGroup>
+
+Claude automatically invokes the relevant Skill if the description matches your request.
+
+## Troubleshooting
+
+### Skills Not Found
+
+**Check settingSources configuration**: Skills are only loaded when you explicitly configure `settingSources`/`setting_sources`. This is the most common issue:
+
+<CodeGroup>
+  ```python Python theme={null}
+  # Wrong - Skills won't be loaded
+  options = ClaudeAgentOptions(
+      allowed_tools=["Skill"]
+  )
+
+  # Correct - Skills will be loaded
+  options = ClaudeAgentOptions(
+      setting_sources=["user", "project"],  # Required to load Skills
+      allowed_tools=["Skill"]
+  )
+  ```
+
+  ```typescript TypeScript theme={null}
+  // Wrong - Skills won't be loaded
+  const options = {
+    allowedTools: ["Skill"]
+  };
+
+  // Correct - Skills will be loaded
+  const options = {
+    settingSources: ["user", "project"],  // Required to load Skills
+    allowedTools: ["Skill"]
+  };
+  ```
+</CodeGroup>
+
+For more details on `settingSources`/`setting_sources`, see the [TypeScript SDK reference](/en/docs/agent-sdk/typescript#settingsource) or [Python SDK reference](/en/docs/agent-sdk/python#settingsource).
+
+**Check working directory**: The SDK loads Skills relative to the `cwd` option. Ensure it points to a directory containing `.claude/skills/`:
+
+<CodeGroup>
+  ```python Python theme={null}
+  # Ensure your cwd points to the directory containing .claude/skills/
+  options = ClaudeAgentOptions(
+      cwd="/path/to/project",  # Must contain .claude/skills/
+      setting_sources=["user", "project"],  # Required to load Skills
+      allowed_tools=["Skill"]
+  )
+  ```
+
+  ```typescript TypeScript theme={null}
+  // Ensure your cwd points to the directory containing .claude/skills/
+  const options = {
+    cwd: "/path/to/project",  // Must contain .claude/skills/
+    settingSources: ["user", "project"],  // Required to load Skills
+    allowedTools: ["Skill"]
+  };
+  ```
+</CodeGroup>
+
+See the "Using Skills with the SDK" section above for the complete pattern.
+
+**Verify filesystem location**:
+
+```bash  theme={null}
+# Check project Skills
+ls .claude/skills/*/SKILL.md
+
+# Check personal Skills
+ls ~/.claude/skills/*/SKILL.md
+```
+
+### Skill Not Being Used
+
+**Check the Skill tool is enabled**: Confirm `"Skill"` is in your `allowedTools`.
+
+**Check the description**: Ensure it's specific and includes relevant keywords. See [Agent Skills Best Practices](/en/docs/agents-and-tools/agent-skills/best-practices#writing-effective-descriptions) for guidance on writing effective descriptions.
+
+### Additional Troubleshooting

+# Agent Skills
+
+> Create, manage, and share Skills to extend Claude's capabilities in Claude Code.
+
+This guide shows you how to create, use, and manage Agent Skills in Claude Code. Skills are modular capabilities that extend Claude's functionality through organized folders containing instructions, scripts, and resources.
+
+## Prerequisites
+
+* Claude Code version 1.0 or later
+* Basic familiarity with [Claude Code](/en/quickstart)
+
+## What are Agent Skills?
+
+Agent Skills package expertise into discoverable capabilities. Each Skill consists of a `SKILL.md` file with instructions that Claude reads when relevant, plus optional supporting files like scripts and templates.
+
+**How Skills are invoked**: Skills are **model-invoked**—Claude autonomously decides when to use them based on your request and the Skill's description. This is different from slash commands, which are **user-invoked** (you explicitly type `/command` to trigger them).
+
+**Benefits**:
+
+* Extend Claude's capabilities for your specific workflows
+* Share expertise across your team via git
+* Reduce repetitive prompting
+* Compose multiple Skills for complex tasks
+
+Learn more in the [Agent Skills overview](https://docs.claude.com/en/docs/agents-and-tools/agent-skills/overview).
+
+<Note>
+  For a deep dive into the architecture and real-world applications of Agent Skills, read our engineering blog: [Equipping agents for the real world with Agent Skills](https://www.anthropic.com/engineering/equipping-agents-for-the-real-world-with-agent-skills).
+</Note>
+
+## Create a Skill
+
+Skills are stored as directories containing a `SKILL.md` file.
+
+### Personal Skills
+
+Personal Skills are available across all your projects. Store them in `~/.claude/skills/`:
+
+```bash  theme={null}
+mkdir -p ~/.claude/skills/my-skill-name
+```
+
+**Use personal Skills for**:
+
+* Your individual workflows and preferences
+* Experimental Skills you're developing
+* Personal productivity tools
+
+### Project Skills
+
+Project Skills are shared with your team. Store them in `.claude/skills/` within your project:
+
+```bash  theme={null}
+mkdir -p .claude/skills/my-skill-name
+```
+
+**Use project Skills for**:
+
+* Team workflows and conventions
+* Project-specific expertise
+* Shared utilities and scripts
+
+Project Skills are checked into git and automatically available to team members.
+
+### Plugin Skills
+
+Skills can also come from [Claude Code plugins](/en/plugins). Plugins may bundle Skills that are automatically available when the plugin is installed. These Skills work the same way as personal and project Skills.
+
+## Write SKILL.md
+
+Create a `SKILL.md` file with YAML frontmatter and Markdown content:
+
+```yaml  theme={null}

+
+# Your Skill Name
+
+## Instructions
+Provide clear, step-by-step guidance for Claude.
+
+## Examples
+Show concrete examples of using this Skill.
+```
+
+**Field requirements**:
+
+* `name`: Must use lowercase letters, numbers, and hyphens only (max 64 characters)
+* `description`: Brief description of what the Skill does and when to use it (max 1024 characters)
+
+The `description` field is critical for Claude to discover when to use your Skill. It should include both what the Skill does and when Claude should use it.
+
+See the [best practices guide](https://docs.claude.com/en/docs/agents-and-tools/agent-skills/best-practices) for complete authoring guidance including validation rules.
+
+## Add supporting files
+
+Create additional files alongside SKILL.md:
+
+```
+my-skill/
+├── SKILL.md (required)
+├── reference.md (optional documentation)
+├── examples.md (optional examples)
+├── scripts/
+│   └── helper.py (optional utility)
+└── templates/
+    └── template.txt (optional template)
+```
+
+Reference these files from SKILL.md:
+
+````markdown  theme={null}
+For advanced usage, see [reference.md](reference.md).
+
+Run the helper script:
+```bash
+python scripts/helper.py input.txt
+```
+````
+
+Claude reads these files only when needed, using progressive disclosure to manage context efficiently.
+
+## Restrict tool access with allowed-tools
+
+Use the `allowed-tools` frontmatter field to limit which tools Claude can use when a Skill is active:
+
+```yaml  theme={null}
+---
+name: safe-file-reader
+description: Read files without making changes. Use when you need read-only file access.
+allowed-tools: Read, Grep, Glob
+---
+
+# Safe File Reader
+
+This Skill provides read-only file access.
+
+## Instructions
+1. Use Read to view file contents
+2. Use Grep to search within files
+3. Use Glob to find files by pattern
+```
+
+When this Skill is active, Claude can only use the specified tools (Read, Grep, Glob) without needing to ask for permission. This is useful for:
+
+* Read-only Skills that shouldn't modify files
+* Skills with limited scope (e.g., only data analysis, no file writing)
+* Security-sensitive workflows where you want to restrict capabilities
+
+If `allowed-tools` is not specified, Claude will ask for permission to use tools as normal, following the standard permission model.
+
+<Note>
+  `allowed-tools` is only supported for Skills in Claude Code.
+</Note>
+
+## View available Skills
+
+Skills are automatically discovered by Claude from three sources:
+
+* Personal Skills: `~/.claude/skills/`
+* Project Skills: `.claude/skills/`
+* Plugin Skills: bundled with installed plugins
+
+**To view all available Skills**, ask Claude directly:
+
+```
+What Skills are available?
+```
+
+or
+
+```
+List all available Skills
+```
+
+This will show all Skills from all sources, including plugin Skills.
+
+**To inspect a specific Skill**, you can also check the filesystem:
+
+```bash  theme={null}
+# List personal Skills
+ls ~/.claude/skills/
+
+# List project Skills (if in a project directory)
+ls .claude/skills/
+
+# View a specific Skill's content
+cat ~/.claude/skills/my-skill/SKILL.md
+```
+
+## Test a Skill
+
+After creating a Skill, test it by asking questions that match your description.
+
+**Example**: If your description mentions "PDF files":
+
+```
+Can you help me extract text from this PDF?
+```
+
+Claude autonomously decides to use your Skill if it matches the request—you don't need to explicitly invoke it. The Skill activates automatically based on the context of your question.
+
+## Debug a Skill
+
+If Claude doesn't use your Skill, check these common issues:
+
+### Make description specific
+
+**Too vague**:
+
+```yaml  theme={null}
+description: Helps with documents
+```
+
+**Specific**:
+
+```yaml  theme={null}
+description: Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
+```
+
+Include both what the Skill does and when to use it in the description.
+
+### Verify file path
+
+**Personal Skills**: `~/.claude/skills/skill-name/SKILL.md`
+**Project Skills**: `.claude/skills/skill-name/SKILL.md`
+
+Check the file exists:
+
+```bash  theme={null}
+# Personal
+ls ~/.claude/skills/my-skill/SKILL.md
+
+# Project
+ls .claude/skills/my-skill/SKILL.md
+```
+
+### Check YAML syntax
+
+Invalid YAML prevents the Skill from loading. Verify the frontmatter:
+
+```bash  theme={null}
+cat SKILL.md | head -n 10
+```
+
+Ensure:
+
+* Opening `---` on line 1
+* Closing `---` before Markdown content
+* Valid YAML syntax (no tabs, correct indentation)
+
+### View errors
+
+Run Claude Code with debug mode to see Skill loading errors:
+
+```bash  theme={null}
+claude --debug
+```
+
+## Share Skills with your team
+
+**Recommended approach**: Distribute Skills through [plugins](/en/plugins).
+
+To share Skills via plugin:
+
+1. Create a plugin with Skills in the `skills/` directory
+2. Add the plugin to a marketplace
+3. Team members install the plugin
+
+For complete instructions, see [Add Skills to your plugin](/en/plugins#add-skills-to-your-plugin).
+
+You can also share Skills directly through project repositories:
+
+### Step 1: Add Skill to your project
+
+Create a project Skill:
+
+```bash  theme={null}
+mkdir -p .claude/skills/team-skill
+# Create SKILL.md
+```
+
+### Step 2: Commit to git
+
+```bash  theme={null}
+git add .claude/skills/
+git commit -m "Add team Skill for PDF processing"
+git push
+```
+
+### Step 3: Team members get Skills automatically
+
+When team members pull the latest changes, Skills are immediately available:
+
+```bash  theme={null}
+git pull
+claude  # Skills are now available
+```
+
+## Update a Skill
+
+Edit SKILL.md directly:
+
+```bash  theme={null}
+# Personal Skill
+code ~/.claude/skills/my-skill/SKILL.md
+
+# Project Skill
+code .claude/skills/my-skill/SKILL.md
+```
+
+Changes take effect the next time you start Claude Code. If Claude Code is already running, restart it to load the updates.
+
+## Remove a Skill
+
+Delete the Skill directory:
+
+```bash  theme={null}
+# Personal
+rm -rf ~/.claude/skills/my-skill
+
+# Project
+rm -rf .claude/skills/my-skill
+git commit -m "Remove unused Skill"
+```
+
+## Best practices
+
+### Keep Skills focused
+
+One Skill should address one capability:
+
+**Focused**:
+
+* "PDF form filling"
+* "Excel data analysis"
+* "Git commit messages"
+
+**Too broad**:
+
+* "Document processing" (split into separate Skills)
+* "Data tools" (split by data type or operation)
+
+### Write clear descriptions
+
+Help Claude discover when to use Skills by including specific triggers in your description:
+
+**Clear**:
+
+```yaml  theme={null}
+description: Analyze Excel spreadsheets, create pivot tables, and generate charts. Use when working with Excel files, spreadsheets, or analyzing tabular data in .xlsx format.
+```
+
+**Vague**:
+
+```yaml  theme={null}
+description: For files
+```
+
+### Test with your team
+
+Have teammates use Skills and provide feedback:
+
+* Does the Skill activate when expected?
+* Are the instructions clear?
+* Are there missing examples or edge cases?
+
+### Document Skill versions
+
+You can document Skill versions in your SKILL.md content to track changes over time. Add a version history section:
+
+```markdown  theme={null}
+# My Skill
+
+## Version History
+- v2.0.0 (2025-10-01): Breaking changes to API
+- v1.1.0 (2025-09-15): Added new features
+- v1.0.0 (2025-09-01): Initial release
+```
+
+This helps team members understand what changed between versions.
+
+## Troubleshooting
+
+### Claude doesn't use my Skill
+
+**Symptom**: You ask a relevant question but Claude doesn't use your Skill.
+
+**Check**: Is the description specific enough?
+
+Vague descriptions make discovery difficult. Include both what the Skill does and when to use it, with key terms users would mention.
+
+**Too generic**:
+
+```yaml  theme={null}
+description: Helps with data
+```
+
+**Specific**:
+
+```yaml  theme={null}
+description: Analyze Excel spreadsheets, generate pivot tables, create charts. Use when working with Excel files, spreadsheets, or .xlsx files.
+```
+
+**Check**: Is the YAML valid?
+
+Run validation to check for syntax errors:
+
+```bash  theme={null}
+# View frontmatter
+cat .claude/skills/my-skill/SKILL.md | head -n 15
+
+# Check for common issues
+# - Missing opening or closing ---
+# - Tabs instead of spaces
+# - Unquoted strings with special characters
+```
+
+**Check**: Is the Skill in the correct location?
+
+```bash  theme={null}
+# Personal Skills
+ls ~/.claude/skills/*/SKILL.md
+
+# Project Skills
+ls .claude/skills/*/SKILL.md
+```
+
+### Skill has errors
+
+**Symptom**: The Skill loads but doesn't work correctly.
+
+**Check**: Are dependencies available?
+
+Claude will automatically install required dependencies (or ask for permission to install them) when it needs them.
+
+**Check**: Do scripts have execute permissions?
+
+```bash  theme={null}
+chmod +x .claude/skills/my-skill/scripts/*.py
+```
+
+**Check**: Are file paths correct?
+
+Use forward slashes (Unix style) in all paths:
+
+**Correct**: `scripts/helper.py`
+**Wrong**: `scripts\helper.py` (Windows style)
+
+### Multiple Skills conflict
+
+**Symptom**: Claude uses the wrong Skill or seems confused between similar Skills.
+
+**Be specific in descriptions**: Help Claude choose the right Skill by using distinct trigger terms in your descriptions.
+
+Instead of:
+
+```yaml  theme={null}
+# Skill 1
+description: For data analysis
+
+# Skill 2
+description: For analyzing data
+```
+
+Use:
+
+```yaml  theme={null}
+# Skill 1
+description: Analyze sales data in Excel files and CRM exports. Use for sales reports, pipeline analysis, and revenue tracking.
+
+# Skill 2
+description: Analyze log files and system metrics data. Use for performance monitoring, debugging, and system diagnostics.
+```
+
+## Examples
+
+### Simple Skill (single file)
+
+```

+# JIT Context Filtering: Post-Mortem
+
+**Date:** November 9, 2025
+**Duration:** 3.5 hours (7:45 PM - 11:11 PM)
+**Branches:** `feature/jit-context`, `failed/jit-context`
+**Status:** Failed, reverted to main
+**Commits:**
+- `3ac0790` - feat: Implement JIT context hook for user prompt submission
+- `adf7bf4` - Refactor JIT context handling in SDKAgent and WorkerService
+
+## Executive Summary
+
+Attempted to implement JIT (Just-In-Time) context filtering—a feature that would dynamically generate relevant context timelines on every user prompt, potentially replacing the static session-start context entirely. After multiple architectural iterations spanning 3.5 hours and adding ~2,850 lines of code, the implementation was abandoned and reverted. The revert was not due to lack of vision (the feature aligns with long-term architectural goals), but due to implementation complexity and the need for a simpler initial approach. Significant architectural knowledge was gained about hook limitations, worker patterns, and proper separation of concerns.
+
+## What We Tried to Build
+
+### Goal
+When a user submits a prompt, dynamically generate a relevant context timeline instead of the static session-start context. Use the fast search infrastructure (SQLite FTS5 + ChromaDB) to fetch precisely relevant context on-demand.
+
+### The Vision
+**Current approach:** SessionStart hook loads 50 recent observations blindly, displays them all.
+
+**Proposed approach:** UserPromptSubmit hook analyzes the prompt, queries the timeline search API, and loads only the relevant context window dynamically.
+
+**Why this makes sense:**
+- We already have fast search: SQLite FTS5 + Chroma semantic search
+- Dynamic context timeline search is implemented and tested
+- Search results come back in <200ms
+- Could **replace** session-start context entirely with smarter, prompt-specific context
+
+### User Experience
+```
+User types: "How did we fix the authentication bug?"
+
+Behind the scenes:
+1. Analyze prompt: "authentication bug fix"
+2. Query timeline search for relevant period
+3. Load 5-10 observations from that specific timeline
+4. Inject as context
+5. Claude answers with precisely relevant historical context
+
+vs. Current:
+Load 50 most recent observations regardless of relevance
+```
+
+### Why Checkbox Settings Became Less Important
+Originally asked for checkboxes to customize session-start context display. But if JIT context could replace session-start context with intelligent, prompt-specific timelines, the display customization became a non-issue.
+
+## Architectural Attempts
+
+### Attempt 1: Hook-Based Filtering (7:45 PM - 9:30 PM)
+
+**Approach:** Call Agent SDK `query()` directly in `new-hook.ts` during UserPromptSubmit event.
+
+**Implementation:**
+- Created `jit-context-hook.ts` (~432 lines)
+- Added `generateJitContext()` function in hook
+- Called SDK `query()` with observation list and user prompt
+- Expected hook to block for ~1-2s while Haiku filters
+
+**Failure:**
+```
+Error: Claude Code executable not found at
+/Users/alexnewman/.claude/plugins/marketplaces/thedotmack/plugin/scripts/cli.js
+```
+
+**Root Cause:** Hooks run in sandboxed environment without access to `claudePath` (path to Claude Code executable). The Agent SDK requires this path, which is only available in the worker service.
+
+**Architectural Violation:** This broke the established pattern where hooks handle orchestration and workers handle AI processing. The `save-hook` sets the precedent: hooks capture data, send to worker, worker runs SDK queries asynchronously.
+
+### Attempt 2: Worker-Based with Simple Queries (9:30 PM - 10:30 PM)
+
+**Approach:** Move JIT filtering to worker service, keep it simple with per-request SDK queries.
+
+**Implementation:**
+- Documented architecture fix plan in `docs/jit-context-architecture-fix.md`
+- Moved `generateJitContext()` to worker (considered creating `src/services/worker/JitContext.ts`)
+- Modified `/sessions/:id/init` endpoint to accept `jitEnabled` flag
+- Worker would run one-shot SDK query per prompt
+
+**Architecture:**
+```
+UserPromptSubmit → new-hook → POST /sessions/:id/init { jitEnabled: true }
+                                      ↓
+                              Worker spawns Claude Haiku
+                                      ↓
+                              Filters 50 obs → 3-5 IDs
+                                      ↓
+                              Returns { context: [...] }
+                                      ↓
+                              Hook injects context → Claude
+```
+
+**Issues Identified:**
+- Each filter request spawns a new Claude subprocess (~200-500ms overhead)
+- Observation list re-sent on every prompt (~5-10KB per request)
+- No token caching between requests
+- Performance worse than just loading all observations directly
+
+**Decision:** Pivoted to persistent sessions to solve performance issues.
+
+### Attempt 3: Persistent JIT Sessions (10:30 PM - 11:11 PM)
+
+**Approach:** Create a long-lived Agent SDK session that persists throughout user session, similar to main memory session pattern.
+
+**Implementation (291 new lines in SDKAgent.ts):**
+
+1. **Session Lifecycle:**
+   - Added `jitSessionId`, `jitAbortController`, `jitGeneratorPromise` to `ActiveSession` interface
+   - `startJitSession()`: Creates persistent SDK session at session init
+   - `cleanupJitSession()`: Terminates JIT session at session end
+
+2. **Request Queue Architecture:**
+   - `jitFilterQueues` Map: Per-session request queues
+   - `JITFilterRequest` interface: `{ userPrompt, resolve, reject }`
+   - EventEmitter coordination: Wake generator when new requests arrive
+
+3. **Message Generator Pattern:**
+   - `createJitMessageGenerator()`: Async generator that yields filter requests
+   - Initial prompt: Load 50 observations, wait for "READY" response
+   - Loop: Wait for EventEmitter signal → yield user prompt → parse response → resolve promise
+   - Pattern: Persistent session stays alive between requests
+
+4. **Filter Query Flow:**
+   ```typescript
+   runFilterQuery(sessionDbId, userPrompt) {
+     // Queue request
+     queue.requests.push({ userPrompt, resolve, reject });
+     queue.emitter.emit('request');
+
+     // Wait for response (30s timeout)
+     return Promise.race([
+       new Promise((resolve, reject) => { /* queued */ }),
+       timeout(30000)
+     ]);
+   }
+   ```
+
+5. **Response Processing:**
+   - `processJitFilterResponse()`: Accumulate streaming text
+   - Parse IDs: "1,5,23,41" or "NONE"
+   - Resolve queued promise with ID array
+
+**Added Files:**
+- `src/services/worker/SDKAgent.ts`: +291 lines
+- `src/services/worker-types.ts`: +3 fields (jit state tracking)
+- `src/services/worker/SessionManager.ts`: +26 lines (JIT cleanup)
+- `src/services/worker-service.ts`: +102 lines (JIT initialization)
+- `src/shared/settings.ts`: +65 lines (JIT config)
+- `src/hooks/jit-context-hook.ts`: +208 lines (orchestration)
+- `docs/jit-context-architecture-fix.md`: +265 lines
+- `context/session-pattern-parity.md`: +298 lines
+
+**Total Changes:** 18 files, +2,852 lines, -133 lines
+
+**Final Status at Revert:** Implementation was complete and likely functional, but...
+
+## Why It Failed
+
+### 1. Architectural Complexity Explosion
+
+**Problem:** The persistent session pattern added enormous complexity for marginal benefit.
+
+**Evidence:**
+- Parallel session management: Regular + JIT sessions running concurrently
+- Complex coordination: EventEmitter + promise queues + generator pattern
+- Lifecycle coupling: Session init, request handling, cleanup all intertwined
+- State explosion: 3 new fields per session (`jitSessionId`, `jitAbortController`, `jitGeneratorPromise`)
+
+**Code Smell:** When the "optimization" requires 300 lines of coordination code, it's probably not an optimization.
+
+### 2. Premature Optimization
+
+**YAGNI Violation:** Built elaborate token caching and persistent session architecture before proving the feature provided value.
+
+**Reality Check:**
+- **Current approach:** Load 50 observations = ~25KB context, works fine
+- **JIT overhead:** Haiku query = 1-2s latency + coordination complexity
+- **User benefit:** Unclear—users haven't complained about context relevance
+- **Token savings:** Marginal—Claude caches long contexts efficiently anyway
+
+**Quote from CLAUDE.md:**
+> "Write the dumb, obvious thing first. Add complexity only when you actually hit the problem."
+
+We didn't hit a problem. We invented one.
+
+### 3. Implementation Complexity, Not Vision
+
+**The Vision is Sound:**
+- Dynamic context is better than static context
+- Timeline search API exists and is fast
+- Infrastructure (SQLite + Chroma) can support this
+- Replacing session-start context with prompt-specific context makes sense
+
+**The Problem:**
+We jumped to the complex persistent-session approach without trying the simple per-request approach first.
+
+**What We Should Have Done:**
+```typescript
+// Simple version (not tried):
+app.post('/sessions/:id/init', async (req, res) => {
+  const { userPrompt } = req.body;
+
+  // Query timeline search API (already exists, fast)
+  const timeline = await timelineSearch(project, userPrompt, depth=10);
+
+  // Return observations
+  return res.json({ context: timeline });
+});
+```
+
+**This would have:**
+- Validated the feature's value quickly
+- Used existing infrastructure
+- Avoided all the persistence complexity
+- Taken 30 minutes instead of 3.5 hours
+
+### 4. Pattern Divergence
+
+**Inconsistency:** JIT sessions work fundamentally differently from memory sessions.
+
+**Memory Session Pattern:**
+```typescript
+// One-shot: Init → Process observations → Complete
+startSession() → yield prompts → parse responses → complete
+```
+
+**JIT Session Pattern:**
+```typescript
+// Persistent: Init → Wait indefinitely → Process on-demand → Complete
+startJitSession() → yield initial load → LOOP:
+  - Wait for EventEmitter signal
+  - Yield filter request
+  - Parse response
+  - Resolve promise
+  - GOTO LOOP
+```
+
+**Maintenance Burden:** Two completely different session patterns means:
+- Doubled testing complexity
+- Increased cognitive load for contributors
+- Higher risk of subtle bugs in lifecycle management
+
+**Session Pattern Parity Document:** The 298-line `session-pattern-parity.md` was created to document the differences—a sign that maybe they shouldn't be different.
+
+### 5. Blocking I/O in Critical Path
+
+**Performance Impact:** Every user prompt now blocks for 1-2s waiting for Haiku filtering.
+
+**Current Flow:**
+```
+User types prompt → 10ms → Claude responds
+```
+
+**JIT Flow:**
+```
+User types prompt → 10ms init → 1-2s Haiku filter → Claude responds
+```
+
+**User Experience:** We added 1-2 seconds of latency to every interaction for questionable benefit.
+
+**Alternative:** If context filtering is valuable, do it asynchronously and apply to next prompt.
+
+### 6. Missing the Forest for the Trees
+
+**Real Issue:** We focused on technical implementation without asking strategic questions:
+
+- **Is context relevance actually a problem?** No evidence.
+- **Do users want this?** No feedback requested.
+- **Is 50 observations too many?** Not proven.
+- **Does filtering improve responses?** Not tested.
+
+**Anti-Pattern:** Solution in search of a problem.
+
+## What We Should Have Done
+
+### Option 1: Don't Build It
+
+**Justification:** No validated user need. Current system works fine.
+
+**Next Step:** Wait for user feedback indicating context relevance is an issue.
+
+### Option 2: Simple MVP
+
+If we really wanted to explore this:
+
+1. **Week 1:** Add basic filtering in worker with one-shot queries
+   - Accept slight performance hit (~500ms overhead)
+   - Measure filter accuracy and user impact
+   - Gather feedback
+
+2. **Week 2:** If proven valuable, optimize
+   - Add token caching only if needed
+   - Consider persistent sessions only if performance is bottleneck
+
+3. **Week 3:** If still valuable, scale
+   - Polish error handling
+   - Add configuration options
+   - Document patterns
+
+**Philosophy:** Incremental validation, not big-bang architecture.
+
+### Option 3: Different Approach Entirely
+
+**Alternative:** Pre-computed relevance scores
+
+Instead of on-demand filtering:
+- Score observations at creation time (save-hook)
+- Store relevance embeddings in Chroma
+- At session start, query Chroma with user's first prompt
+- Load top 10-20 most relevant observations
+- No runtime latency, better accuracy, simpler architecture
+
+**Benefit:** Leverages existing Chroma infrastructure, avoids runtime overhead.
+
+## Technical Lessons Learned
+
+### 1. EventEmitter Coordination Anti-Pattern
+
+**Code:**
+```typescript
+queue.emitter.on('request', () => {
+  // Wake up generator to process request
+});
+```
+
+**Issue:** Complex async coordination using event-driven wakeup signals is hard to reason about.
+
+**Better:** Use async queues or channels (e.g., `async-queue` package) that handle coordination internally.
+
+### 2. Generator Pattern Complexity
+
+**Pattern:**
+```typescript
+async *createJitMessageGenerator() {
+  yield initialPrompt;
+  while (!aborted) {
+    await waitForEvent();  // Blocks here
+    yield nextRequest;
+  }
+}
+```
+
+**Tradeoff:** Generators are great for iteration, but terrible for event-driven request/response patterns.
+
+**Better:** Use explicit session object with `sendMessage()/waitForResponse()` methods.
+
+### 3. Dual Session Management
+
+**Complexity:** Managing two concurrent SDK sessions per user session is inherently complex.
+
+**Alternatives Considered:**
+- Single session handling both observations and filtering (rejected: tight coupling)
+- Separate service for filtering (rejected: too much infrastructure)
+- Pre-computed filtering (not considered: should have been)
+
+**Lesson:** When parallel state management feels hard, question whether you need parallel state.
+
+### 4. Promise Queue Pattern
+
+**Implementation:**
+```typescript
+interface QueuedRequest {
+  resolve: (result: T) => void;
+  reject: (error: Error) => void;
+}
+queue.push({ resolve, reject });
+// Later...
+queue[0].resolve(result);
+```
+
+**Good:** Clean async API for callers
+**Bad:** Easy to leak promises if error handling isn't perfect
+**Improvement:** Use libraries like `p-queue` that handle edge cases
+
+## Process Lessons Learned
+
+### 1. No Incremental Validation
+
+**Mistake:** Went from "idea" to "complete architecture" without validation points.
+
+**Better Process:**
+1. Write one-pager explaining user value
+2. Build simplest possible version (2 hours max)
+3. Test with real usage
+4. Measure impact
+5. Decide: kill, iterate, or scale
+
+**Checkpoint Questions:**
+- After 1 hour: "Does this solve a real problem?"
+- After 2 hours: "Is this getting too complex?"
+- After 3 hours: "Should I just ship the simple version?"
+
+### 2. Architecture Astronomy
+
+**Definition:** Designing elaborate systems without building/testing them.
+
+**Evidence:**
+- 265-line architecture doc written before any code
+- 298-line session pattern parity analysis
+- Multiple complete rewrites of the same feature
+
+**Better:** Code first, document later. Spike solutions, learn from implementation.
+
+### 3. Sunk Cost Fallacy
+
+**Timeline:**
+- **Hour 1:** "This seems complex but achievable"
+- **Hour 2:** "We're halfway done, can't stop now"
+- **Hour 3:** "Just need to fix this one coordination issue"
+- **Hour 4:** "It's working, but... this feels wrong"
+
+**Correct Decision:** Revert. Took courage to throw away 4 hours of work.
+
+**Learning:** Time invested is not a reason to continue. Quality of outcome matters more.
+
+### 4. Missing User Feedback Loop
+
+**No User Input:**
+- Didn't ask: "Is context relevance a problem for you?"
+- Didn't test: "Does filtered context improve your responses?"
+- Didn't measure: "Are you hitting context limits?"
+
+**Engineering Theater:** Building impressive-sounding features without user validation.
+
+## What We Actually Learned (The Real Value)
+
+Despite reverting, this was productive R&D:
+
+### 1. Deep Understanding of Hook Architecture
+
+**Critical Discovery:** Hooks run in sandboxed environment without `claudePath`.
+- Hooks cannot call Agent SDK `query()` directly
+- All AI processing must happen in worker service
+- This architectural constraint is now documented
+
+**Learned Pattern:**
+```
+Hook (orchestration) → Worker (AI processing)
+✓ save-hook: Captures data → Worker processes with SDK
+✓ new-hook: Creates session → Worker returns confirmation
+✗ jit-hook: Tried SDK in hook → Failed, no claudePath
+```
+
+**Value:** Future features will avoid this mistake. We now know the boundary.
+
+### 2. Worker Architecture Patterns
+
+**Blocking vs. Non-Blocking:**
+- SessionStart: Can be non-blocking (context loads async)
+- UserPromptSubmit: Must be blocking (session must exist before processing)
+- JIT Context: Must be blocking (context needed before prompt processed)
+
+**Established Pattern:**
+```typescript
+// Worker endpoint for features requiring AI
+app.post('/sessions/:id/operation', async (req, res) => {
+  const { operationData } = req.body;
+  const result = await sdkAgent.performOperation(operationData);
+  return res.json({ result });
+});
+```
+
+### 3. Persistent Session Management
+
+**Architecture Knowledge Gained:**
+- How to maintain long-lived SDK sessions
+- EventEmitter coordination patterns for request/response
+- Promise queue management for async operations
+- Proper cleanup with AbortControllers
+
+**Pattern Documented:**
+- Dual session management (regular + JIT)
+- Generator-based message loops
+- Request queuing with timeouts
+
+**Value:** When we build the simpler version, we'll know these patterns.
+
+### 4. Configuration Infrastructure
+
+`src/shared/settings.ts` (65 lines) provides reusable configuration patterns:
+```typescript
+export function getConfigValue(key: string, defaultValue: string): string {
+  // Priority: settings.json → env var → default
+}
+```
+
+**Kept After Revert:** This module is useful for other features.
+
+### 5. Key Architectural Decisions Made
+
+**Decisions that will guide future implementation:**
+1. JIT context filtering must happen in worker (proven via failed hook attempt)
+2. Context must be blocking on UserPromptSubmit (session needs context before processing)
+3. Dynamic timeline search is the right approach (fast, precise, leverages existing infrastructure)
+4. Simple per-request queries should be tried before persistent sessions
+
+### 6. Documentation Quality
+
+- `jit-context-architecture-fix.md`: Documents why hooks can't run SDK queries
+- `session-pattern-parity.md`: Reference for implementing dual sessions
+- Hooks reference: Comprehensive hook documentation added
+
+**Value:** These docs help future contributors understand the system constraints.
+
+### 7. Infrastructure Validation
+
+**Confirmed that our search stack is ready:**
+- SQLite FTS5: Fast full-text search (<50ms)
+- ChromaDB: Semantic search (<200ms with 8,000+ vectors)
+- Timeline search API: Already implemented and tested
+- Worker service: Can handle synchronous AI operations
+
+**The infrastructure exists. We just need a simpler integration.**
+
+## Recommendations
+
+### Immediate Actions
+
+1. **Archive the work:**
+   - Keep `failed/jit-context` branch for reference
+   - Extract reusable components (settings.ts)
+   - Save architecture docs for future features
+
+2. **Document the anti-patterns:**
+   - Add this post-mortem to CLAUDE.md references
+   - Update coding standards with lessons learned
+
+3. **Reset focus:**
+   - Return to validated user needs
+   - Prioritize features with clear value propositions
+
+### Future Feature Development
+
+**Gating Questions (Answer before coding):**
+
+1. **User Value:** What specific user problem does this solve?
+2. **Evidence:** Have users requested this or reported the underlying issue?
+3. **Measurement:** How will we know if it's successful?
+4. **Simplicity:** What's the dumbest version that could work?
+5. **Time Limit:** If we can't prove value in 2 hours, should we build it?
+
+**Process:**
+
+```
+VALIDATE → BUILD SIMPLE → TEST → MEASURE → DECIDE
+   ↑                                          ↓
+   └──────────── ITERATE OR KILL ────────────┘
+```
+
+### If Context Filtering Returns
+
+Should we revisit this idea in the future:
+
+**Prerequisites:**
+- User feedback requesting better context relevance
+- Metrics showing current context is too broad
+- Evidence that filtering improves response quality
+
+**Simple Approach:**
+```typescript
+// In worker-service.ts /sessions/:id/init
+if (jitEnabled) {
+  const observations = await db.getRecentObservations(project, 50);
+  const filtered = await simpleFilter(observations, userPrompt);  // One-shot query
+  return { context: filtered };
+}
+```
+
+**Acceptance Criteria:**
+- <100 lines of code
+- <500ms latency impact
+- No new session types
+- Degrades gracefully on errors
+
+**If that works:** Then consider optimization.
+
+## Conclusion
+
+JIT context filtering failed not because the vision was wrong, but because we jumped to the complex implementation without validating the simple one first. The feature aligns with long-term goals (dynamic, prompt-specific context using our fast search infrastructure), but the persistent-session architecture was premature optimization.
+
+**The right call:** Revert the complex implementation. Build the simple version when ready.
+
+**Key Takeaway:** The vision is sound. The execution was overcomplicated. We now have:
+- Deep knowledge of hook/worker architecture constraints
+- Documented patterns for persistent SDK sessions
+- Validated fast search infrastructure
+- Clear understanding of what to build next time (simple timeline search API integration)
+
+**This was R&D, not failure.** We learned what doesn't work (SDK in hooks), what does work (worker-based AI processing), and how to approach it next time (simple API calls before persistent sessions).
+
+**Next Implementation:**
+When we revisit this (and we should), start with:
+1. Worker endpoint that accepts prompt
+2. Queries existing timeline search API
+3. Returns context
+4. Hook injects context
+5. Validate it improves responses
+6. Then optimize if needed
+
+**Final Thought:** Sometimes you have to build the wrong thing to understand the right thing. That's R&D.
+
+---
+
+**Branch Status:**
+- `feature/jit-context`: Abandoned
+- `failed/jit-context`: Archived for reference
+- `main`: Stable at v5.4.0
+
+**Files to Keep:**
+- `src/shared/settings.ts`: Reusable config utilities
+
+**Files Discarded:**
+- Everything else (+2,850 lines)
+
+**Emotional State:** Relieved. Dodged a maintenance nightmare.

-      "created_at": "2025-11-06T10:25:00Z"
-    },
-    {
-      "type": "user-prompt",
-      "id": 45,
-      "prompt": "User request",
-      "created_at": "2025-11-06T10:28:00Z"
-    },
-    {
-      "type": "observation",
-      "id": 123,
-      "title": "Anchor observation",
-      "created_at": "2025-11-06T10:30:00Z",
-      "isAnchor": true
-    },
-    {
-      "type": "session",
-      "id": "S456",
-      "request": "Session summary",
-      "created_at": "2025-11-06T10:32:00Z"
-    }
-  ],
-  "anchor": {
-    "type": "observation",
-    "id": 123
-  }
-}
-```
-
-### 9. get_timeline_by_query
-
-Search for observations using natural language and get timeline context around the best match. Combines search + timeline into a single operation.
-
-**Parameters**:
-- `query` (required): Natural language search query to find relevant observations
-- `mode` (default: "auto"): Operation mode
-  - `"auto"`: Automatically use top search result as timeline anchor
-  - `"interactive"`: Return top N search results for manual anchor selection
-- `depth_before` (default: 10): Number of timeline records before anchor (max: 50)
-- `depth_after` (default: 10): Number of timeline records after anchor (max: 50)
-- `limit` (default: 5): For interactive mode - number of top search results to display (max: 20)
-- `project`: Filter by project name
-
-**Use Case**: Faster context discovery - "show me what happened around when we fixed the authentication bug"
-
-**Example - Auto Mode**:
-```
-# Automatically find and show timeline for "authentication bug"
-get_timeline_by_query with query="authentication bug" and mode="auto" and depth_before=10 and depth_after=10
-```
-
-**Example - Interactive Mode**:
-```
-# Show top 5 matches, let user choose anchor
-get_timeline_by_query with query="authentication bug" and mode="interactive" and limit=5
-```
-
-**Auto Mode Response**:
-```json
-{
-  "search_result": {
-    "id": 123,
-    "title": "Fix authentication bug",
-    "relevance": 0.95
-  },
-  "timeline": [
-    /* timeline records before and after observation 123 */
-  ]
-}
-```
-
-**Interactive Mode Response**:
-```json
-{
-  "top_results": [
-    {
-      "id": 123,
-      "title": "Fix authentication bug",
-      "relevance": 0.95,
-      "created_at": "2025-11-06T10:30:00Z"
-    },
-    {
-      "id": 98,
-      "title": "Authentication refactor",
-      "relevance": 0.82,
-      "created_at": "2025-11-05T14:20:00Z"
-    }
-  ],
-  "message": "Select an observation ID to view its timeline context"
-}
-```
-
-## Output Formats
-
-All search tools support two output formats:
-
-### Index Format (Default)
-
-Returns titles, dates, and source URIs only. Uses ~10x fewer tokens than full format.
-
-**Always use index format first** to get an overview and identify relevant results.
-
-**Example Output**:
-```
-1. [decision] Implement graceful session cleanup
-   Date: 2025-10-21 14:23:45
-   Source: claude-mem://observation/123
-
-2. [feature] Add FTS5 full-text search
-   Date: 2025-10-21 13:15:22
-   Source: claude-mem://observation/124
-```
-
-### Full Format
-
-Returns complete observation/summary details including narrative, facts, concepts, files, etc.
-
-**Only use after reviewing index results** to dive deep into specific items of interest.
-
-## Search Strategy
-
-**Recommended Workflow**:
-
-1. **Initial search**: Use default (index) format to see titles, dates, and sources
-2. **Review results**: Identify which items are most relevant to your needs
-3. **Deep dive**: Only then use `format: "full"` on specific items of interest
-4. **Narrow down**: Use filters (type, dateRange, concepts, files) to refine results
-
-**Token Efficiency**:
-- Index format: ~50-100 tokens per result
-- Full format: ~500-1000 tokens per result
-- Start with 3-5 results to avoid MCP token limits
-
-## Citations
-
-All search results use the `claude-mem://` URI scheme for citations:
-
-- `claude-mem://observation/{id}` - References specific observations
-- `claude-mem://session/{id}` - References specific sessions
-- `claude-mem://user-prompt/{id}` - References specific user prompts
-
-These citations allow Claude to reference specific historical context in responses.
-
-## FTS5 Query Syntax
-
-The `query` parameter supports SQLite FTS5 full-text search syntax:
-
-- **Simple**: `"error handling"`
-- **AND**: `"error" AND "handling"`
-- **OR**: `"bug" OR "fix"`
-- **NOT**: `"bug" NOT "feature"`
-- **Phrase**: `"'exact phrase'"`
-- **Column**: `title:"authentication"`
-
-## Security
-
-As of v4.2.3, all FTS5 queries are properly escaped to prevent SQL injection attacks:
-- Double quotes are escaped: `query.replace(/"/g, '""')`
-- Comprehensive test suite with 332 injection attack tests
-- Affects: `search_observations`, `search_sessions`, `search_user_prompts`
-
-## Example Queries
-
-```
-# Find all decisions about build system
-search_observations with query="build system" and type="decision"
-
-# Show everything related to worker-service.ts
-find_by_file with filePath="worker-service.ts"
-
-# Search what we learned about hooks
-search_sessions with query="hooks"
-
-# Show observations tagged with 'architecture'
-find_by_concept with concept="architecture"
-
-# Find what user asked about authentication
-search_user_prompts with query="authentication"
-
-# Get recent context for debugging
-get_recent_context with limit=5
-
-# Timeline around a specific observation
-get_context_timeline with anchor=123 and depth_before=10 and depth_after=10
-
-# Quick timeline search for authentication work
-get_timeline_by_query with query="authentication bug" and mode="auto"
-```
-
-## Implementation
-
-The MCP search server is implemented using:
-- `@modelcontextprotocol/sdk` (v1.20.1)
-- `SessionSearch` service for FTS5 queries
-- `SessionStore` for database access
-- `zod-to-json-schema` for parameter validation
-
-**Source Code**: `src/servers/search-server.ts`
-
-## Troubleshooting
-
-### Tool Not Available
-
-If search tools are not available in Claude Code sessions:
-
-1. Check MCP configuration:
-   ```bash
-   cat plugin/.mcp.json
-   ```
-
-2. Verify search server is built:
-   ```bash
-   ls -l plugin/scripts/search-server.mjs
-   ```
-
-3. Rebuild if needed:
-   ```bash
-   npm run build
-   ```
-
-### Search Returns No Results
-
-1. Check database has data:
-   ```bash
-   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
-   ```
-
-2. Verify FTS5 tables exist:
-   ```bash
-   sqlite3 ~/.claude-mem/claude-mem.db "SELECT name FROM sqlite_master WHERE type='table' AND name LIKE '%_fts';"
-   ```
-
-3. Test query syntax:
-   ```bash
-   # Simple query should work
-   search_observations with query="test"
-   ```
-
-### Token Limit Errors
-
-If you hit MCP token limits:
-
-1. Use `format: "index"` instead of `format: "full"`
-2. Reduce `limit` parameter (try 3-5 instead of 20)
-3. Use more specific filters to narrow results
-4. Use `offset` to paginate through results

+
+# Search Architecture
+
+Claude-Mem uses a skill-based search architecture that provides intelligent memory retrieval through natural language queries. This replaced the MCP-based approach in v5.4.0, saving ~2,250 tokens per session start.
+
+## Overview
+
+**Architecture**: Skill-Based Search + HTTP API + Progressive Disclosure
+
+**Key Components**:
+1. **Search Skill** (`plugin/skills/search/SKILL.md`) - Auto-invoked when users ask about past work
+2. **HTTP API Endpoints** (10 routes) - Fast, efficient search operations on port 37777
+3. **Worker Service** - Express.js server with FTS5 full-text search
+4. **SQLite Database** - Persistent storage with FTS5 virtual tables
+5. **Chroma Vector DB** - Semantic search with hybrid retrieval
+
+## How It Works
+
+### 1. User Query (Natural Language)
+
+```
+User: "What bugs did we fix last session?"
+```
+
+### 2. Skill Invocation
+
+Claude recognizes the intent and invokes the search skill:
+- Skill frontmatter (~250 tokens) loaded at session start
+- Full skill instructions loaded on-demand when skill is invoked
+- Progressive disclosure pattern minimizes context overhead
+
+### 3. HTTP API Call
+
+The skill uses `curl` to call the HTTP API:
+
+```bash
+curl "http://localhost:37777/api/search/observations?query=bugs&type=bugfix&limit=5"
+```
+
+### 4. FTS5 Search
+
+Worker service queries SQLite FTS5 virtual tables:
+
+```sql
+SELECT * FROM observations_fts
+WHERE observations_fts MATCH ?
+AND type = 'bugfix'
+ORDER BY rank
+LIMIT 5
+```
+
+### 5. Results Formatted
+
+Skill formats results and returns to Claude:
+
+```
+## Recent Bugfixes
+
+1. [bugfix] Fixed authentication token expiry
+   Date: 2025-11-08 14:23:45
+   Files: src/auth/jwt.ts
+
+2. [bugfix] Resolved database connection leak
+   Date: 2025-11-08 13:15:22
+   Files: src/services/database.ts
+```
+
+### 6. User Sees Answer
+
+Claude presents the formatted results naturally in conversation.
+
+## Architecture Change (v5.4.0)
+
+### Before: MCP-Based Search
+
+**Approach**: 9 MCP tools registered at session start
+
+**Token Cost**: ~2,500 tokens in tool definitions per session
+- Each tool's schema, parameters, descriptions loaded
+- All 9 tools available whether needed or not
+- No progressive disclosure
+
+**Example MCP Tool**:
+```json
+{
+  "name": "search_observations",
+  "description": "Full-text search across observations...",
+  "inputSchema": {
+    "type": "object",
+    "properties": {
+      "query": { "type": "string", "description": "..." },
+      "type": { "type": "array", "items": { "enum": [...] } },
+      "format": { "enum": ["index", "full"] },
+      // ... many more parameters
+    }
+  }
+}
+```
+
+### After: Skill-Based Search
+
+**Approach**: 1 search skill with progressive disclosure
+
+**Token Cost**: ~250 tokens in skill frontmatter per session
+- Only skill description loaded at session start
+- Full instructions loaded on-demand when skill is invoked
+- HTTP API endpoints instead of MCP protocol
+
+**Example Skill Frontmatter**:
+```markdown
+# Claude-Mem Search Skill
+
+Access claude-mem's persistent memory through a comprehensive HTTP API.
+Search for past work, understand context, and learn from previous decisions.
+
+## When to Use This Skill
+
+Invoke this skill when users ask about:
+- Past work: "What did we do last session?"
+- Bug fixes: "Did we fix this before?"
+- Features: "How did we implement authentication?"
+...
+```
+
+**Token Savings**: ~2,250 tokens per session start (90% reduction)
+
+## HTTP API Endpoints
+
+The worker service exposes 10 search endpoints:
+
+### Full-Text Search
+
+```
+GET /api/search/observations
+GET /api/search/sessions
+GET /api/search/prompts
+```
+
+**Parameters**:

+- `type` - Filter by type (bugfix, feature, refactor, etc.)
+- `project` - Filter by project name
+- `limit` - Maximum results (default: 20)
+- `offset` - Pagination offset
+- `format` - Response format (index or full)
+
+**Example**:
+```bash
+curl "http://localhost:37777/api/search/observations?query=authentication&type=decision&limit=5"
+```
+
+### Filtered Search
+
+```
+GET /api/search/by-type
+GET /api/search/by-concept

+```
+
+### Context Retrieval
+
+```
+GET /api/context/recent
+GET /api/context/timeline
+GET /api/timeline/by-query
+```
+
+**Parameters**:
+- `project` - Filter by project
+- `limit` - Number of sessions/records
+- `anchor` - Timeline anchor point (ID or timestamp)
+- `depth_before` - Records before anchor
+- `depth_after` - Records after anchor
+
+**Example**:
+```bash
+curl "http://localhost:37777/api/context/recent?project=claude-mem&limit=5"
+```
+
+### Documentation
+
+```
+GET /api/search/help
+```
+
+Returns API documentation in JSON format.
+
+## Progressive Disclosure Pattern
+
+The search skill uses progressive disclosure to minimize token usage:
+
+### Layer 1: Skill Frontmatter (Session Start)
+
+**What's Loaded**: Skill description and when to use it (~250 tokens)
+
+**Purpose**: Claude can recognize when to invoke the skill
+
+**Example**:
+```markdown
+# Claude-Mem Search Skill
+
+Access claude-mem's persistent memory through a comprehensive HTTP API.
+
+## When to Use This Skill
+Invoke this skill when users ask about:
+- Past work: "What did we do last session?"
+- Bug fixes: "Did we fix this before?"
+...
+```
+
+### Layer 2: Full Skill Instructions (On-Demand)
+
+**What's Loaded**: Complete operation documentation (~2,500 tokens)
+
+**Purpose**: Detailed instructions for each search operation
+
+**When Loaded**: Only when Claude invokes the skill
+
+**Example Structure**:
+```
+/skills/search/
+├── SKILL.md (main frontmatter)
+├── operations/
+│   ├── observations.md (detailed instructions)
+│   ├── sessions.md
+│   ├── prompts.md

+│   ├── timeline-by-query.md
+│   ├── help.md
+│   ├── formatting.md
+│   └── common-workflows.md
+```
+
+### Layer 3: API Response
+
+**What's Returned**: Search results in requested format
+
+**Format Options**:
+- `index` - Titles, dates, IDs only (~50-100 tokens per result)
+- `full` - Complete details (~500-1000 tokens per result)
+
+**Progressive Usage**: Start with `index`, drill down with `full` as needed

+```
+
+### Worker Service Integration
+
+**File**: `src/services/worker-service.ts`
+
+**Search Routes**:
+```typescript
+// Full-text search
+app.get('/api/search/observations', handleSearchObservations);
+app.get('/api/search/sessions', handleSearchSessions);
+app.get('/api/search/prompts', handleSearchPrompts);
+
+// Filtered search
+app.get('/api/search/by-type', handleSearchByType);
+app.get('/api/search/by-concept', handleSearchByConcept);
+app.get('/api/search/by-file', handleSearchByFile);
+
+// Context retrieval
+app.get('/api/context/recent', handleRecentContext);
+app.get('/api/context/timeline', handleTimeline);
+app.get('/api/timeline/by-query', handleTimelineByQuery);
+
+// Documentation
+app.get('/api/search/help', handleHelp);
+```
+
+**Database Access**:
+- Uses `SessionSearch` service for FTS5 queries
+- Uses `SessionStore` for structured queries
+- Hybrid search with ChromaDB for semantic similarity
+
+### Security
+
+**FTS5 Injection Prevention** (v4.2.3):
+```typescript
+function escapeFTS5Query(query: string): string {
+  return query.replace(/"/g, '""');
+}
+```
+
+All user-provided search queries are properly escaped to prevent SQL injection.
+
+**Comprehensive Testing**: 332 injection attack tests covering:
+- Special characters
+- SQL keywords
+- Quote escaping
+- Boolean operators
+
+## Benefits
+
+### 1. Token Efficiency
+
+**Before (MCP)**:
+- Session start: ~2,500 tokens for tool definitions
+- Every session pays this cost
+- No progressive disclosure
+
+**After (Skill)**:
+- Session start: ~250 tokens for skill frontmatter
+- Full instructions: ~2,500 tokens (only when invoked)
+- Net savings: ~2,250 tokens per session (~90% reduction)
+
+### 2. Natural Language Interface
+
+**Before**: Users needed to learn MCP tool syntax
+```
+search_observations with query="authentication" and type="decision"
+```
+
+**After**: Users ask naturally
+```
+"What decisions did we make about authentication?"
+```
+
+Claude translates to appropriate API call.
+
+### 3. Flexibility
+
+**HTTP API Benefits**:
+- Can be called from skills, MCP tools, or other clients
+- Easy to test with curl
+- Standard REST conventions
+- JSON responses
+
+**Progressive Disclosure**:
+- Loads only what's needed
+- Can add more operations without increasing base cost
+- Documentation co-located with operations
+
+### 4. Performance
+
+**Fast Queries**: FTS5 full-text search <10ms for typical queries
+
+**Caching**: HTTP layer allows response caching
+
+**Pagination**: Efficient result pagination with offset/limit
+
+## Migration Notes
+
+### For Users
+
+**No Action Required**: The migration from MCP to skill-based search is transparent.
+
+**Same Questions Work**: Natural language queries work exactly the same way.
+
+**Invisible Change**: Users won't notice any difference except better performance.
+
+### For Developers
+
+**Deprecated**: MCP search server (`src/servers/search-server.ts`)
+- Source file kept for reference
+- No longer built or registered
+- MCP configuration removed from `plugin/.mcp.json`
+
+**New Implementation**: Skill-based search
+- Skill files: `plugin/skills/search/`
+- HTTP endpoints: `src/services/worker-service.ts` (lines 200-400)
+- Build script: `npm run build` includes skill files
+- Sync script: `npm run sync-marketplace` copies to plugin directory
+
+## Troubleshooting
+
+### Worker Service Not Running
+
+If searches fail, check worker service:
+
+```bash
+pm2 list                    # Check status
+npm run worker:restart      # Restart worker
+npm run worker:logs         # View logs
+```
+
+### HTTP Endpoints Not Responding
+
+Test endpoints directly:
+
+```bash
+# Health check
+curl http://localhost:37777/health
+
+# Search test
+curl "http://localhost:37777/api/search/observations?query=test&limit=1"
+```
+
+### Skill Not Invoking
+
+If Claude doesn't invoke the skill:
+
+1. Check skill files exist: `ls ~/.claude/plugins/marketplaces/thedotmack/plugin/skills/search/`
+2. Restart Claude Code session
+3. Try explicit skill invocation: `/skill search`

-# MCP Search Tools Usage
+# Skill-Based Search Usage
 
-Once claude-mem is installed as a plugin, 9 search tools become available in your Claude Code sessions for querying project history.
+Once claude-mem is installed as a plugin, you can search your project history using natural language. Claude automatically invokes the search skill when you ask about past work.
+
+## How It Works
+
+**v5.4.0 Migration**: Claude-Mem now uses a skill-based search architecture instead of MCP tools, saving ~2,250 tokens per session start through progressive disclosure.
+
+**Simple Usage:**
+- Just ask naturally: *"What did we do last session?"*
+- Claude recognizes the intent and invokes the search skill
+- The skill uses HTTP API endpoints to query your memory
+- Results are formatted and presented to you
+
+**Benefits:**
+- **Token Efficient**: ~250 tokens (skill frontmatter) vs ~2,500 tokens (MCP tool definitions)
+- **Natural Language**: No need to learn specific tool syntax
+- **Progressive Disclosure**: Only loads detailed instructions when needed
+- **Auto-Invoked**: Claude knows when to search based on your questions

-get_timeline_by_query with query="authentication implementation"
-```
-Automatically uses the top search result as timeline anchor and returns surrounding context.
-
-**Interactive mode:**
-```
-get_timeline_by_query with query="authentication" and mode="interactive" and limit=5
-```
-Shows top 5 search results for you to manually choose which to use as timeline anchor.

-- Investigate issues: Find a bug fix and see what led to it
-- Decision archaeology: Search for a decision and understand the context
-- Feature timeline: See the complete story of a feature implementation
-
-**Benefits:**
-- Single-step operation (no need to search, then timeline separately)
-- Auto mode provides instant context
-- Interactive mode gives you control over anchor selection
-- Natural language search makes it easy to find relevant moments
+- All record types (observations, sessions, prompts) in chronological view
+- Understand what was happening before and after important changes
 
 ## Search Strategy
 
-### 1. Start with Index Format
+The search skill uses a progressive disclosure pattern to efficiently retrieve information:
 
-**Always use index format first** to get an overview:
+### 1. Ask Naturally
 
+Start with a natural language question:
 ```
-search_observations with query="authentication" and format="index"
+"What bugs did we fix related to authentication?"
 ```
 
-**Why?**
-- Index format uses ~10x fewer tokens than full format
-- See titles, dates, and sources to identify relevant results
-- Avoid hitting MCP token limits
+### 2. Claude Invokes Search Skill
 
-### 2. Review Results
+Claude recognizes your intent and loads the search skill (~250 tokens for skill frontmatter).
 
-Look at the index results to identify items of interest:
+### 3. Skill Uses HTTP API
 
+The skill calls the appropriate HTTP endpoint (e.g., `/api/search/observations`) with the query.
+
+### 4. Results Formatted
+
+Results are formatted and presented to you, usually starting with an index/summary format.
+
+### 5. Deep Dive if Needed
+
+If you need more details, ask follow-up questions:
 ```
-1. [decision] Implement JWT authentication
-   Date: 2025-10-21 14:23:45
-   Source: claude-mem://observation/123
-
-2. [feature] Add user authentication endpoints
-   Date: 2025-10-21 13:15:22
-   Source: claude-mem://observation/124
-
-3. [bugfix] Fix authentication token expiry
-   Date: 2025-10-20 16:45:30
-   Source: claude-mem://observation/125
+"Tell me more about observation #123"
+"Show me the full details of that decision"
 ```
 
-### 3. Deep Dive with Full Format
-
-Only use full format for specific items:
-
-```
-search_observations with query="JWT authentication" and format="full" and limit=3
-```
-
-### 4. Use Filters to Narrow Results
-
-Combine filters for precise searches:
-
-```
-search_observations with query="authentication" and type="decision" and dateRange={start: "2025-10-20", end: "2025-10-21"}
-```
+**Benefits of This Approach:**
+- **Token Efficient**: Only loads what you need, when you need it
+- **Natural**: No syntax to learn
+- **Progressive**: Start with overview, drill down as needed
+- **Automatic**: Claude handles the search invocation
 
 ## Advanced Filtering
 
+You can refine searches using natural language filters:
+
 ### Date Ranges
 
-Search within specific time periods:
-
-```json
-{
-  "dateRange": {
-    "start": "2025-10-01",
-    "end": "2025-10-31"
-  }
-}
 ```
-
-Or use epoch timestamps:
-
-```json
-{
-  "dateRange": {
-    "start": 1729449600,
-    "end": 1732128000
-  }
-}
+"What bugs did we fix in October?"
+"Show me work from last week"
+"Find decisions made between October 1-31"
 ```
 
 ### Multiple Types
 
-Search across multiple observation types:
-
 ```
-find_by_type with type=["decision", "feature", "refactor"]
+"Show me all decisions and features"
+"Find bugfixes and refactorings"
 ```
 
-### Multiple Concepts
-
-Search observations with specific concepts:
+### Concepts
 
 ```
-search_observations with query="database" and concepts=["architecture", "performance"]
+"Find database work related to architecture and performance"
+"Show security observations"
 ```
 
-### File Filtering
-
-Search observations that touched specific files:
+### File-Specific
 
 ```
-search_observations with query="refactor" and files="worker-service.ts"
+"Show refactoring work that touched worker-service.ts"
+"Find changes to auth files"
 ```
 
 ### Project Filtering
 
-Search within specific projects:
-
 ```
-search_observations with query="authentication" and project="my-app"
+"Show authentication work on my-app project"
+"What have we done on this codebase?"
 ```
 
-## FTS5 Query Syntax
+**Note**: Claude translates your natural language into the appropriate API filters automatically.
 
-The `query` parameter supports SQLite FTS5 full-text search syntax:
+## Under the Hood: HTTP API
 
-### Simple Queries
-```
-"authentication"           # Single word
-"error handling"           # Multiple words (OR)
-```
+The search skill uses HTTP endpoints on the worker service (port 37777):
 
-### Boolean Operators
-```
-"error" AND "handling"     # Both terms required
-"bug" OR "fix"             # Either term
-"bug" NOT "feature"        # First term, not second
-```
+- `GET /api/search/observations` - Full-text search observations
+- `GET /api/search/sessions` - Full-text search session summaries
+- `GET /api/search/prompts` - Full-text search user prompts
+- `GET /api/search/by-concept` - Find observations by concept tag
+- `GET /api/search/by-file` - Find work related to specific files
+- `GET /api/search/by-type` - Find observations by type
+- `GET /api/context/recent` - Get recent session context
+- `GET /api/context/timeline` - Get timeline around specific point
+- `GET /api/timeline/by-query` - Search + timeline in one call
+- `GET /api/search/help` - API documentation
 
-### Phrase Searches
-```
-"'exact phrase'"           # Exact phrase match
-```
-
-### Column Searches
-```
-title:"authentication"     # Search specific column
-narrative:"bug fix"        # Search narrative field
-```
+These endpoints use FTS5 full-text search with support for:
+- Boolean operators (AND, OR, NOT)
+- Phrase searches
+- Column-specific searches
+- Date range filtering
+- Project filtering

-### Token Limit Errors
+### Worker Service Not Running
 
-1. Use index format:
-   ```
-   search_observations with query="..." and format="index"
-   ```
+If search isn't working, check the worker service:
 
-2. Reduce limit:
-   ```
-   search_observations with query="..." and limit=3
-   ```
+```bash
+pm2 list                    # Check worker status
+npm run worker:restart      # Restart if needed
+npm run worker:logs         # View logs
+```
 
-3. Use pagination:
-   ```
-   # First page
-   search_observations with query="..." and limit=5 and offset=0
+Or use the troubleshooting skill:
+```
+/skill troubleshoot
+```
 
-   # Second page
-   search_observations with query="..." and limit=5 and offset=5
-   ```
+### Performance Issues
 
-### Search Too Slow
+If searches seem slow:
+1. Be more specific in your queries
+2. Ask for recent work (naturally filters by date)
+3. Specify the project you're interested in
+4. Ask for fewer results initially
 
-1. Use more specific queries
-2. Add date range filters
-3. Add type/concept filters
-4. Reduce result limit
+## Technical Details
+
+**Architecture Change (v5.4.0)**:
+- **Before**: 9 MCP tools (~2,500 tokens in tool definitions per session start)
+- **After**: 1 search skill (~250 tokens in frontmatter, full instructions loaded on-demand)
+- **Savings**: ~2,250 tokens per session start
+- **Migration**: Transparent - users don't need to change how they ask questions
+
+**How the Skill Works:**
+1. User asks a question about past work
+2. Claude recognizes the intent matches the search skill description
+3. Skill loads full instructions from `plugin/skills/search/SKILL.md`
+4. Skill uses `curl` to call HTTP API endpoints
+5. Results formatted and returned to Claude
+6. Claude presents results to user

+description: Search claude-mem persistent memory for past sessions, observations, bugs fixed, features implemented, decisions made, code changes, and previous work. Use when answering questions about history, finding past decisions, or researching previous implementations.
+---
+
+# Claude-Mem Search Skill
+
+Access claude-mem's persistent memory through a comprehensive HTTP API. Search for past work, understand context, and learn from previous decisions.
+
+## When to Use This Skill
+
+**Invoke this skill when users ask about:**
+- Past work: "What did we do last session?"
+- Bug fixes: "Did we fix this before?" or "What bugs did we fix?"
+- Features: "How did we implement authentication?"
+- Decisions: "Why did we choose this approach?"
+- Code changes: "What files were modified in that refactor?"
+- File history: "What changes to auth/login.ts?"
+- Timeline context: "What was happening around that time?"
+- Recent activity: "What have we been working on?"
+
+**Do NOT invoke** for current session work or future planning (use regular tools for that).
+
+## Quick Decision Guide
+
+Once the skill is loaded, choose the appropriate operation:
+
+**What are you looking for?**
+
+- "What did we do last session?" → [operations/recent-context.md](operations/recent-context.md)
+- "Did we fix this bug before?" → [operations/by-type.md](operations/by-type.md) (type=bugfix)
+- "How did we implement X?" → [operations/observations.md](operations/observations.md)
+- "What changes to file.ts?" → [operations/by-file.md](operations/by-file.md)
+- "What was happening then?" → [operations/timeline.md](operations/timeline.md)
+- "Why did we choose X?" → [operations/observations.md](operations/observations.md) (search for decisions)
+
+## Available Operations
+
+Choose the appropriate operation file for detailed instructions:
+
+### Full-Text Search
+1. **[Search Observations](operations/observations.md)** - Find observations by keyword (bugs, features, decisions, etc.)
+2. **[Search Sessions](operations/sessions.md)** - Search session summaries to understand what was accomplished
+3. **[Search Prompts](operations/prompts.md)** - Find what users have asked about in the past
+
+### Filtered Search
+4. **[Search by Type](operations/by-type.md)** - Find bugfix, feature, refactor, decision, or discovery observations
+5. **[Search by Concept](operations/by-concept.md)** - Find observations tagged with specific concepts
+6. **[Search by File](operations/by-file.md)** - Find all work related to a specific file path
+
+### Context Retrieval
+7. **[Get Recent Context](operations/recent-context.md)** - Get recent session summaries and observations for a project
+8. **[Get Timeline](operations/timeline.md)** - Get chronological timeline around a specific point in time
+9. **[Timeline by Query](operations/timeline-by-query.md)** - Search then get timeline around the best match
+
+### Utilities
+10. **[API Help](operations/help.md)** - Get API documentation
+
+## Common Workflows
+
+For step-by-step guides on typical user requests, see [operations/common-workflows.md](operations/common-workflows.md):
+- Understanding past work
+- Finding specific bug fixes
+- Understanding file history
+- Timeline investigation
+
+## Response Formatting
+
+For guidelines on how to present search results to users, see [operations/formatting.md](operations/formatting.md):
+- Format=index responses (compact lists)
+- Format=full responses (complete details)
+- Timeline responses (chronologically grouped)
+
+## Technical Notes
+
+- **Port:** Default 37777 (configurable via `CLAUDE_MEM_WORKER_PORT`)
+- **Response format:** Always JSON
+- **Search type:** FTS5 full-text search + structured filters
+- **All operations use HTTP GET** with query parameters
+
+## Performance Tips
+
+1. Use **format=index** first for overviews, then **format=full** for details
+2. Start with **limit=5-10**, expand if needed
+3. Use **project filtering** when working on one codebase
+4. Use **timeline depth** of 5-10 for focused context
+5. Be specific in search queries: "authentication JWT" > "auth"
+
+## Error Handling
+
+If HTTP request fails:
+1. Inform user the search service isn't available
+2. Suggest checking if worker is running: `pm2 list`
+3. Offer to help troubleshoot
+
+For detailed error handling, see the specific operation files.

+# Search by Concept
+
+Find observations tagged with specific concepts.
+
+## When to Use
+
+- Looking for observations about a specific concept
+- Understanding patterns across the codebase
+- Finding related learnings
+
+## Command
+
+```bash
+curl -s "http://localhost:37777/api/search/by-concept?concept=discovery&limit=5&format=index"
+```
+
+## Parameters
+
+- **concept** (required): Concept tag to search for
+- **format**: "index" or "full" (default: "full")
+- **limit**: Number of results (default: 10, max: 100)
+- **project**: Filter by project name (optional)
+
+## Common Concepts
+
+- **discovery**: Learnings and findings
+- **decision**: Choices and rationale
+- **architecture**: System design
+- **performance**: Speed and optimization
+- **security**: Security considerations
+- **testing**: Test-related work

+- **why-it-exists**: Rationale and context
+- **gotcha**: Tricky issues or edge cases
+- **pattern**: Reusable patterns
+
+## Use Case
+
+"What have we learned about the database?" → Search concept=discovery + keyword search for "database"
+
+You can combine concept search with keyword search:
+```bash
+# First get observations with concept=discovery
+curl -s "http://localhost:37777/api/search/by-concept?concept=discovery&limit=20&format=index"
+# Then filter results for "database" mentions
+```
+
+## How to Present Results
+
+```markdown
+Found 5 discoveries:
+
+1. 🔵 **#1230** Database connection pooling best practices
+   > Learned that pool size should match CPU cores * 2

+### Observation #1234: Implemented JWT authentication
+
+**Type:** Feature 🟣
+**Project:** claude-mem
+**Date:** Nov 9, 2024 3:30 PM
+
+**Summary:** Added token-based auth with refresh tokens
+
+**Details:**
+Implemented a complete JWT authentication system for the API. The system uses
+short-lived access tokens (15 minutes) combined with longer-lived refresh tokens
+(7 days) to balance security and user experience. The implementation includes
+middleware for route protection and automatic token refresh handling.
+
+**Facts:**
+- Used jsonwebtoken library (v9.0.2)
+- Access tokens expire after 15 minutes
+- Refresh tokens expire after 7 days
+- Tokens include user ID and role claims
+- Added rate limiting to auth endpoints
+
+**Files Modified:**
+- src/auth/jwt.ts (created, 145 lines)
+- src/middleware/auth.ts (created, 78 lines)
+- src/routes/auth.ts (created, 92 lines)
+- tests/auth.test.ts (created, 234 lines)
+
+**Concepts:** authentication, security, tokens, middleware
+```
+
+### Sessions (Full)
+
+```markdown
+### Session #123: Add user authentication (Nov 8, 2024)
+
+**Request:** Implement JWT-based authentication for the API
+
+**Completed:**
+- Implemented JWT authentication system with access and refresh tokens
+- Created authentication middleware for route protection
+- Added login, logout, and token refresh endpoints
+- Wrote comprehensive tests for auth flows
+- Added rate limiting to prevent brute force attacks
+
+**Learned:**
+- JWT refresh token rotation is critical for security
+- Need to handle token expiration gracefully on client side
+- Rate limiting should be IP-based for auth endpoints
+- Token blacklisting adds complexity, short expiration is simpler
+
+**Next Steps:**
+- Add password reset functionality
+- Implement 2FA for admin accounts
+- Add OAuth integration for social login
+
+**Files Read:**
+- docs/authentication-spec.md
+- src/middleware/existing-auth.ts

+## Error Responses
+
+### No Results
+
+```markdown
+No results found for "foobar". Try different search terms or:
+- Check spelling
+- Use broader terms
+- Try synonyms
+- Search by type or concept instead
+```
+
+### Service Unavailable
+
+```markdown
+Search service is not available. The claude-mem worker may not be running.
+
+To check worker status:
+\`\`\`bash
+pm2 list
+\`\`\`
+
+To restart the worker:
+\`\`\`bash
+pm2 restart claude-mem-worker
+\`\`\`

+
+## General Formatting Tips
+
+1. **Use markdown formatting**: Bold, headers, code blocks, quotes
+2. **Be concise**: Users want quick answers, not walls of text
+3. **Highlight key information**: IDs, dates, types
+4. **Group related items**: By day, by type, by file
+5. **Offer follow-ups**: "Want more details?" "See timeline?"
+6. **Use visual hierarchy**: Headers, lists, indentation
+7. **Include context**: Project names, dates, related observations
+8. **Make IDs clickable-ready**: **#1234** stands out for reference

+# Timeline by Query
+
+Search for something, then automatically get timeline context around the best match.
+
+## When to Use
+
+- User asks: "What led to the authentication refactor?"
+- Want to find something AND see surrounding context in one request
+- Understand the full story with minimal requests
+
+## Command
+
+```bash
+curl -s "http://localhost:37777/api/timeline/by-query?query=authentication+refactor&mode=auto&depth_before=10&depth_after=10"
+```
+
+## Parameters
+
+- **query** (required): Search terms
+- **mode**: Where to search (default: "auto")
+  - `"auto"`: Search both observations and sessions, return best match
+  - `"observations"`: Search only observations
+  - `"sessions"`: Search only sessions
+- **depth_before**: Records before match (default: 10, max: 50)
+- **depth_after**: Records after match (default: 10, max: 50)
+- **project**: Filter by project name (optional)
+
+## Response Structure
+
+Returns both the best match AND timeline around it:
+
+```json
+{
+  "query": "authentication refactor",
+  "mode": "auto",
+  "match": {
+    "type": "observation",
+    "id": 1234,

+  "timeline": {
+    "observations": [...],
+    "sessions": [...],
+    "prompts": [...]
+  }
+}
+```
+
+## Use Case: "What led to the authentication refactor?"
+
+One query gets both:
+1. The authentication refactor observation (best match)
+2. Complete timeline before and after showing what led to it
+
+```bash
+curl -s "http://localhost:37777/api/timeline/by-query?query=authentication+refactor&depth_before=10&depth_after=10"

+
+## Tips
+
+1. This is the most efficient operation for "what led to X" questions
+2. One request instead of two (search + timeline)
+3. Use mode="auto" to search both observations and sessions
+4. Adjust depth based on how much context you need

+```
+
+**Expected output:** `{"status":"ok"}`
+
+**What it does:**
+1. Stops the worker (if running)
+2. Ensures dependencies are installed
+3. Starts worker with local PM2
+4. Waits for startup
+5. Verifies health
+
+## Fix: Worker Not Running
+
+**Use when:** PM2 shows worker as stopped or not listed
+
+```bash
+cd ~/.claude/plugins/marketplaces/thedotmack/ && \
+node_modules/.bin/pm2 start ecosystem.config.cjs && \
+sleep 2 && \
+pm2 status
+```
+
+**Expected output:** Worker shows as "online"
+
+## Fix: Dependencies Missing
+
+**Use when:** Worker won't start due to missing packages
+
+```bash
+cd ~/.claude/plugins/marketplaces/thedotmack/ && \
+npm install && \
+pm2 restart claude-mem-worker
+```
+
+## Fix: Port Conflict
+
+**Use when:** Error shows port already in use
+
+```bash
+# Change to port 37778
+mkdir -p ~/.claude-mem && \
+echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json && \
+pm2 restart claude-mem-worker && \
+sleep 2 && \
+curl -s http://127.0.0.1:37778/health
+```
+
+**Expected output:** `{"status":"ok"}`
+
+## Fix: Database Issues
+
+**Use when:** Database appears corrupted or out of sync
+
+```bash
+# Backup and test integrity
+cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup && \
+sqlite3 ~/.claude-mem/claude-mem.db "PRAGMA integrity_check;" && \
+pm2 restart claude-mem-worker
+```
+
+**If integrity check fails, recreate database:**
+```bash
+# WARNING: This deletes all memory data
+mv ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.old && \
+pm2 restart claude-mem-worker
+```
+
+## Fix: Clean Reinstall
+
+**Use when:** All else fails, nuclear option
+
+```bash
+# Backup data first
+cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup 2>/dev/null
+
+# Stop and remove worker
+pm2 delete claude-mem-worker 2>/dev/null
+
+# Reinstall dependencies
+cd ~/.claude/plugins/marketplaces/thedotmack/ && \
+rm -rf node_modules && \
+npm install
+
+# Start worker
+node_modules/.bin/pm2 start ecosystem.config.cjs && \
+sleep 3 && \
+curl -s http://127.0.0.1:37777/health
+```
+
+## Fix: Clear PM2 Logs
+
+**Use when:** Logs are too large, want fresh start
+
+```bash
+pm2 flush claude-mem-worker && \
+pm2 restart claude-mem-worker
+```
+
+## Verification Commands
+
+**After running any fix, verify with these:**
+
+```bash
+# Check worker status
+pm2 status | grep claude-mem-worker
+
+# Check health
+curl -s http://127.0.0.1:37777/health
+
+# Check database
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
+
+# Check viewer
+curl -s http://127.0.0.1:37777/api/stats
+
+# Check logs for errors
+pm2 logs claude-mem-worker --lines 20 --nostream | grep -i error
+```
+
+**All checks should pass:**
+- Worker status: "online"
+- Health: `{"status":"ok"}`
+- Database: Shows count (may be 0 if new)
+- Stats: Returns JSON with counts
+- Logs: No recent errors
+
+## Troubleshooting the Fixes
+
+**If automated fix fails:**
+1. Run the diagnostic script from [diagnostics.md](diagnostics.md)
+2. Check specific error in PM2 logs
+3. Try manual worker start to see detailed error:
+   ```bash
+   cd ~/.claude/plugins/marketplaces/thedotmack/
+   node plugin/scripts/worker-service.cjs
+   ```

+# Common Issue Resolutions
+
+Quick fixes for frequently encountered claude-mem problems.
+
+## Issue: Nothing is Remembered After `/clear` {#nothing-remembered}
+
+**Symptoms:**
+- Data doesn't persist across sessions
+- Context is empty after `/clear`
+- Search returns no results for past work
+
+**Root cause:** Sessions are marked complete but data should persist. This suggests:
+- Worker not processing observations
+- Database not being written to
+- Context hook not reading from database
+
+**Fix:**
+1. Verify worker is running:
+   ```bash
+   pm2 jlist | grep claude-mem-worker
+   ```
+
+2. Check database has recent observations:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations WHERE created_at > datetime('now', '-1 day');"
+   ```
+
+3. Restart worker and start new session:
+   ```bash
+   pm2 restart claude-mem-worker
+   ```
+
+4. Create a test observation: `/skill version-bump` then cancel
+
+5. Check if observation appears in viewer:
+   ```bash
+   open http://127.0.0.1:37777
+   # Or manually check database:
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT * FROM observations ORDER BY created_at DESC LIMIT 1;"
+   ```
+
+## Issue: Viewer Empty After Every Claude Restart {#viewer-empty}
+
+**Symptoms:**
+- Viewer shows no data at http://127.0.0.1:37777
+- Stats endpoint returns all zeros
+- Database appears empty in UI
+
+**Root cause:**
+- Database being recreated on startup (shouldn't happen)
+- Worker reading from wrong database location
+- Database permissions issue
+
+**Fix:**
+1. Check database file exists and has data:
+   ```bash
+   ls -lh ~/.claude-mem/claude-mem.db
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
+   ```
+
+2. Check file permissions:
+   ```bash
+   ls -la ~/.claude-mem/claude-mem.db
+   # Should be readable/writable by your user
+   ```
+
+3. Verify worker is using correct database path in logs:
+   ```bash
+   pm2 logs claude-mem-worker --lines 50 --nostream | grep "Database"
+   ```
+
+4. Test viewer connection manually:
+   ```bash
+   curl -s http://127.0.0.1:37777/api/stats
+   # Should show non-zero counts if data exists
+   ```
+
+## Issue: Old Memory in Claude {#old-memory}
+
+**Symptoms:**
+- Context contains outdated observations
+- Irrelevant past work appearing in sessions
+- Context feels stale
+
+**Root cause:** Context hook injecting stale observations
+
+**Fix:**
+1. Check the observation count setting:
+   ```bash
+   grep CLAUDE_MEM_CONTEXT_OBSERVATIONS ~/.claude/settings.json
+   ```
+
+2. Default is 50 observations - you can adjust this:
+   ```json
+   {
+     "env": {
+       "CLAUDE_MEM_CONTEXT_OBSERVATIONS": "25"
+     }
+   }
+   ```
+
+3. Check database for actual observation dates:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT created_at, project, title FROM observations ORDER BY created_at DESC LIMIT 10;"
+   ```
+
+4. Consider filtering by project if working on multiple codebases
+
+## Issue: Worker Not Starting {#worker-not-starting}
+
+**Symptoms:**
+- PM2 shows worker as "stopped" or "errored"
+- Health check fails
+- Viewer not accessible
+
+**Root cause:**
+- Port already in use
+- PM2 not installed or not in PATH
+- Missing dependencies
+
+**Fix:**
+1. Try manual worker start to see error:
+   ```bash
+   cd ~/.claude/plugins/marketplaces/thedotmack/
+   node plugin/scripts/worker-service.cjs
+   # Should start server on port 37777 or show error
+   ```
+
+2. If port in use, change it:
+   ```bash
+   mkdir -p ~/.claude-mem
+   echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json
+   ```
+
+3. If dependencies missing:
+   ```bash
+   cd ~/.claude/plugins/marketplaces/thedotmack/
+   npm install
+   pm2 start ecosystem.config.cjs
+   ```
+
+## Issue: Search Results Empty
+
+**Symptoms:**
+- Search skill returns no results
+- API endpoints return empty arrays
+- Know there's data but can't find it
+
+**Root cause:**
+- FTS5 tables not synchronized
+- Wrong project filter
+- Database not being queried correctly
+
+**Fix:**
+1. Check if observations exist in database:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
+   ```
+
+2. Check FTS5 table sync:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations_fts;"
+   # Should match observation count
+   ```
+
+3. Try search via API directly:
+   ```bash
+   curl "http://127.0.0.1:37777/api/search/observations?q=test&format=index"
+   ```
+
+4. If FTS5 out of sync, restart worker (triggers reindex):
+   ```bash
+   pm2 restart claude-mem-worker
+   ```
+
+## Issue: Port Conflicts
+
+**Symptoms:**
+- Worker won't start
+- Error: "EADDRINUSE: address already in use"
+- Health check fails
+
+**Fix:**
+1. Check what's using port 37777:
+   ```bash
+   lsof -i :37777
+   ```
+
+2. Either kill the conflicting process or change claude-mem port:
+   ```bash
+   mkdir -p ~/.claude-mem
+   echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json
+   pm2 restart claude-mem-worker
+   ```
+
+## Issue: Database Corrupted
+
+**Symptoms:**
+- SQLite errors in logs
+- Worker crashes on startup
+- Queries fail
+
+**Fix:**
+1. Backup the database:
+   ```bash
+   cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup
+   ```
+
+2. Try to repair:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "PRAGMA integrity_check;"
+   ```
+
+3. If repair fails, recreate (loses data):
+   ```bash
+   rm ~/.claude-mem/claude-mem.db
+   pm2 restart claude-mem-worker
+   # Worker will create new database
+   ```
+
+## Prevention Tips
+
+**Keep claude-mem healthy:**
+- Regularly check viewer UI to see if observations are being captured
+- Monitor database size (shouldn't grow unbounded)
+- Update plugin when new versions are released
+- Keep Claude Code updated
+
+**Performance tuning:**
+- Adjust `CLAUDE_MEM_CONTEXT_OBSERVATIONS` if context is too large/small
+- Use `/clear` to mark sessions complete and start fresh
+- Use search skill to query specific memories instead of loading everything

+# Database Diagnostics
+
+SQLite database troubleshooting for claude-mem.
+
+## Database Overview
+
+Claude-mem uses SQLite3 for persistent storage:
+- **Location:** `~/.claude-mem/claude-mem.db`
+- **Library:** better-sqlite3 (synchronous, not bun:sqlite)
+- **Features:** FTS5 full-text search, triggers, indexes
+- **Tables:** observations, sessions, user_prompts, observations_fts, sessions_fts, prompts_fts
+
+## Basic Database Checks
+
+### Check Database Exists
+
+```bash
+# Check file exists
+ls -lh ~/.claude-mem/claude-mem.db
+
+# Check file size
+du -h ~/.claude-mem/claude-mem.db
+
+# Check permissions
+ls -la ~/.claude-mem/claude-mem.db
+```
+
+**Expected:**
+- File exists
+- Size: 100KB - 10MB+ (depends on usage)
+- Permissions: Readable/writable by your user
+
+### Check Database Integrity
+
+```bash
+# Run integrity check
+sqlite3 ~/.claude-mem/claude-mem.db "PRAGMA integrity_check;"
+```
+
+**Expected output:** `ok`
+
+**If errors appear:**
+- Database corrupted
+- Backup immediately: `cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup`
+- Consider recreating (data loss)
+
+## Data Inspection
+
+### Count Records
+
+```bash
+# Observation count
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
+
+# Session count
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM sessions;"
+
+# User prompt count
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM user_prompts;"
+
+# FTS5 table counts (should match main tables)
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations_fts;"
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM sessions_fts;"
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM prompts_fts;"
+```
+
+### View Recent Records
+
+```bash
+# Recent observations
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  created_at,
+  type,
+  title,
+  project
+FROM observations
+ORDER BY created_at DESC
+LIMIT 10;
+"
+
+# Recent sessions
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  created_at,
+  request,
+  project
+FROM sessions
+ORDER BY created_at DESC
+LIMIT 5;
+"
+
+# Recent user prompts
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  created_at,
+  prompt
+FROM user_prompts
+ORDER BY created_at DESC
+LIMIT 10;
+"
+```
+
+### Check Projects
+
+```bash
+# List all projects
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT DISTINCT project
+FROM observations
+ORDER BY project;
+"
+
+# Count observations per project
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  project,
+  COUNT(*) as count
+FROM observations
+GROUP BY project
+ORDER BY count DESC;
+"
+```
+
+## Database Schema
+
+### View Table Structure
+
+```bash
+# List all tables
+sqlite3 ~/.claude-mem/claude-mem.db ".tables"
+
+# Show observations table schema
+sqlite3 ~/.claude-mem/claude-mem.db ".schema observations"
+
+# Show all schemas
+sqlite3 ~/.claude-mem/claude-mem.db ".schema"
+```
+
+### Expected Tables
+
+- `observations` - Main observation records
+- `observations_fts` - FTS5 virtual table for full-text search
+- `sessions` - Session summary records
+- `sessions_fts` - FTS5 virtual table for session search
+- `user_prompts` - User prompt records
+- `prompts_fts` - FTS5 virtual table for prompt search
+
+## FTS5 Synchronization
+
+The FTS5 tables should stay synchronized with main tables via triggers.
+
+### Check FTS5 Sync
+
+```bash
+# Compare counts
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  (SELECT COUNT(*) FROM observations) as observations,
+  (SELECT COUNT(*) FROM observations_fts) as observations_fts,
+  (SELECT COUNT(*) FROM sessions) as sessions,
+  (SELECT COUNT(*) FROM sessions_fts) as sessions_fts,
+  (SELECT COUNT(*) FROM user_prompts) as prompts,
+  (SELECT COUNT(*) FROM prompts_fts) as prompts_fts;
+"
+```
+
+**Expected:** All pairs should match (observations = observations_fts, etc.)
+
+### Fix FTS5 Desync
+
+If FTS5 counts don't match, triggers may have failed. Restart worker to rebuild:
+
+```bash
+pm2 restart claude-mem-worker
+```
+
+The worker will rebuild FTS5 indexes on startup if they're out of sync.
+
+## Common Database Issues
+
+### Issue: Database Doesn't Exist
+
+**Cause:** First run, or database was deleted
+
+**Fix:** Database will be created automatically on first observation. No action needed.
+
+### Issue: Database is Empty (0 Records)
+
+**Cause:**
+- New installation (normal)
+- Data was deleted
+- Worker not processing observations
+
+**Fix:**
+1. Create test observation (use any skill and cancel)
+2. Check worker logs for errors:
+   ```bash
+   pm2 logs claude-mem-worker --lines 50 --nostream
+   ```
+3. Verify observation appears in database
+
+### Issue: Database Permission Denied
+
+**Cause:** File permissions wrong, database owned by different user
+
+**Fix:**
+```bash
+# Check ownership
+ls -la ~/.claude-mem/claude-mem.db
+
+# Fix permissions (if needed)
+chmod 644 ~/.claude-mem/claude-mem.db
+chown $USER ~/.claude-mem/claude-mem.db
+```
+
+### Issue: Database Locked
+
+**Cause:**
+- Multiple processes accessing database
+- Crash left lock file
+- Long-running transaction
+
+**Fix:**
+```bash
+# Check for lock file
+ls -la ~/.claude-mem/claude-mem.db-wal
+ls -la ~/.claude-mem/claude-mem.db-shm
+
+# Remove lock files (only if worker is stopped!)
+pm2 stop claude-mem-worker
+rm ~/.claude-mem/claude-mem.db-wal ~/.claude-mem/claude-mem.db-shm
+pm2 start claude-mem-worker
+```
+
+### Issue: Database Growing Too Large
+
+**Cause:** Too many observations accumulated
+
+**Check size:**
+```bash
+du -h ~/.claude-mem/claude-mem.db
+sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
+```
+
+**Options:**
+1. Delete old observations (manual cleanup):
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "
+   DELETE FROM observations
+   WHERE created_at < datetime('now', '-90 days');
+   "
+   ```
+
+2. Vacuum to reclaim space:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "VACUUM;"
+   ```
+
+3. Archive and start fresh:
+   ```bash
+   mv ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.archive
+   pm2 restart claude-mem-worker
+   ```
+
+## Database Recovery
+
+### Backup Database
+
+**Before any destructive operations:**
+```bash
+cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup
+```
+
+### Restore from Backup
+
+```bash
+pm2 stop claude-mem-worker
+cp ~/.claude-mem/claude-mem.db.backup ~/.claude-mem/claude-mem.db
+pm2 start claude-mem-worker
+```
+
+### Export Data
+
+Export to JSON for safekeeping:
+
+```bash
+# Export observations
+sqlite3 ~/.claude-mem/claude-mem.db -json "SELECT * FROM observations;" > observations.json
+
+# Export sessions
+sqlite3 ~/.claude-mem/claude-mem.db -json "SELECT * FROM sessions;" > sessions.json
+
+# Export prompts
+sqlite3 ~/.claude-mem/claude-mem.db -json "SELECT * FROM user_prompts;" > prompts.json
+```
+
+### Recreate Database
+
+**WARNING: Data loss. Backup first!**
+
+```bash
+# Stop worker
+pm2 stop claude-mem-worker
+
+# Backup current database
+cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.old
+
+# Delete database
+rm ~/.claude-mem/claude-mem.db
+
+# Start worker (creates new database)
+pm2 start claude-mem-worker
+```
+
+## Database Statistics
+
+### Storage Analysis
+
+```bash
+# Database file size
+du -h ~/.claude-mem/claude-mem.db
+
+# Record counts by type
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  type,
+  COUNT(*) as count
+FROM observations
+GROUP BY type
+ORDER BY count DESC;
+"
+
+# Observations per month
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  strftime('%Y-%m', created_at) as month,
+  COUNT(*) as count
+FROM observations
+GROUP BY month
+ORDER BY month DESC;
+"
+
+# Average observation size (characters)
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT
+  AVG(LENGTH(content)) as avg_content_length,
+  MAX(LENGTH(content)) as max_content_length
+FROM observations;
+"
+```
+
+## Advanced Queries
+
+### Find Specific Observations
+
+```bash
+# Search by keyword (FTS5)
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT title, created_at
+FROM observations_fts
+WHERE observations_fts MATCH 'authentication'
+ORDER BY created_at DESC;
+"
+
+# Find by type
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT title, created_at
+FROM observations
+WHERE type = 'bugfix'
+ORDER BY created_at DESC
+LIMIT 10;
+"
+
+# Find by file path
+sqlite3 ~/.claude-mem/claude-mem.db "
+SELECT title, created_at
+FROM observations
+WHERE file_path LIKE '%auth%'
+ORDER BY created_at DESC;
+"
+```
+
+## Database Maintenance
+
+### Regular Maintenance Tasks
+
+```bash
+# Analyze for query optimization
+sqlite3 ~/.claude-mem/claude-mem.db "ANALYZE;"
+
+# Rebuild FTS5 indexes
+sqlite3 ~/.claude-mem/claude-mem.db "
+INSERT INTO observations_fts(observations_fts) VALUES('rebuild');
+INSERT INTO sessions_fts(sessions_fts) VALUES('rebuild');
+INSERT INTO prompts_fts(prompts_fts) VALUES('rebuild');
+"
+
+# Vacuum to reclaim space
+sqlite3 ~/.claude-mem/claude-mem.db "VACUUM;"
+```
+
+**Run monthly to keep database healthy.**

-   sqlite3 ~/.claude-mem/claude-mem.db "SELECT created_at, project, title FROM observations ORDER BY created_at DESC LIMIT 10;"
-   ```
-
-### Issue: "Worker not starting"
-
-**Root cause:**
-- Port already in use
-- PM2 not installed or not in PATH
-- Missing dependencies
-
-**Fix:**
-1. Try manual worker start:
-   ```bash
-   cd ~/.claude/plugins/marketplaces/thedotmack/
-   node plugin/scripts/worker-service.cjs
-   # Should start server on port 37777
-   ```
-2. If port in use, change it:
-   ```bash
-   echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json
-   ```

-## Prevention Tips
-
-**Keep claude-mem healthy:**
-- Regularly check viewer UI to see if observations are being captured
-- Monitor database size (shouldn't grow unbounded)
-- Update plugin when new versions are released
-- Keep Claude Code updated
-
-**Performance tuning:**
-- Adjust `CLAUDE_MEM_CONTEXT_OBSERVATIONS` if context is too large/small
-- Use `/clear` to mark sessions complete and start fresh
-- Use MCP search tools to query specific memories instead of loading everything

+# Worker Service Diagnostics
+
+PM2 worker-specific troubleshooting for claude-mem.
+
+## PM2 Worker Overview
+
+The claude-mem worker is a persistent background service managed by PM2. It:
+- Runs Express.js server on port 37777 (default)
+- Processes observations asynchronously
+- Serves the viewer UI
+- Provides search API endpoints
+
+## Check Worker Status
+
+### Basic Status Check
+
+```bash
+# List all PM2 processes
+pm2 list
+
+# JSON format (parseable)
+pm2 jlist
+
+# Filter for claude-mem-worker
+pm2 status | grep claude-mem-worker
+```
+
+**Expected output:**
+```
+│ claude-mem-worker │ online    │ 12345  │ 0    │ 45m │ 0% │ 85.6mb │
+```
+
+**Status meanings:**
+- `online` - Worker running correctly
+- `stopped` - Worker stopped (normal shutdown)
+- `errored` - Worker crashed (check logs)
+- `stopping` - Worker shutting down
+- Not listed - Worker never started
+
+### Detailed Worker Info
+
+```bash
+# Show detailed information
+pm2 show claude-mem-worker
+
+# JSON format
+pm2 jlist | grep -A 20 '"name":"claude-mem-worker"'
+```
+
+## Worker Health Endpoint
+
+The worker exposes a health endpoint at `/health`:
+
+```bash
+# Check health (default port)
+curl -s http://127.0.0.1:37777/health
+
+# With custom port
+PORT=$(grep CLAUDE_MEM_WORKER_PORT ~/.claude-mem/settings.json | grep -o '[0-9]\+' || echo "37777")
+curl -s http://127.0.0.1:$PORT/health
+```
+
+**Expected response:** `{"status":"ok"}`
+
+**Error responses:**
+- Connection refused - Worker not running
+- Timeout - Worker hung (restart needed)
+- Empty response - Worker crashed mid-request
+
+## Worker Logs
+
+### View Recent Logs
+
+```bash
+# Last 50 lines
+pm2 logs claude-mem-worker --lines 50 --nostream
+
+# Last 200 lines
+pm2 logs claude-mem-worker --lines 200 --nostream
+
+# Follow logs in real-time
+pm2 logs claude-mem-worker
+```
+
+### Search Logs for Errors
+
+```bash
+# Find errors
+pm2 logs claude-mem-worker --lines 500 --nostream | grep -i "error"
+
+# Find exceptions
+pm2 logs claude-mem-worker --lines 500 --nostream | grep -i "exception"
+
+# Find failed requests
+pm2 logs claude-mem-worker --lines 500 --nostream | grep -i "failed"
+
+# All error patterns
+pm2 logs claude-mem-worker --lines 500 --nostream | grep -iE "error|exception|failed|crash"
+```
+
+### Common Log Patterns
+
+**Good startup:**
+```
+Worker service started on port 37777
+Database initialized
+Express server listening
+```
+
+**Database errors:**
+```
+Error: SQLITE_ERROR
+Error initializing database
+Database locked
+```
+
+**Port conflicts:**
+```
+Error: listen EADDRINUSE
+Port 37777 already in use
+```
+
+**Crashes:**
+```
+PM2        | App [claude-mem-worker] exited with code [1]
+PM2        | App [claude-mem-worker] will restart in 100ms
+```
+
+## Starting the Worker
+
+### Basic Start
+
+```bash
+cd ~/.claude/plugins/marketplaces/thedotmack/
+pm2 start ecosystem.config.cjs
+```
+
+### Start with Local PM2
+
+If `pm2` command not in PATH:
+
+```bash
+cd ~/.claude/plugins/marketplaces/thedotmack/
+node_modules/.bin/pm2 start ecosystem.config.cjs
+```
+
+### Force Restart
+
+```bash
+# Restart if already running
+pm2 restart claude-mem-worker
+
+# Delete and start fresh
+pm2 delete claude-mem-worker
+pm2 start ecosystem.config.cjs
+```
+
+## Stopping the Worker
+
+```bash
+# Graceful stop
+pm2 stop claude-mem-worker
+
+# Delete completely (also removes from PM2 list)
+pm2 delete claude-mem-worker
+```
+
+## Worker Not Starting
+
+### Diagnostic Steps
+
+1. **Try manual start to see error:**
+   ```bash
+   cd ~/.claude/plugins/marketplaces/thedotmack/
+   node plugin/scripts/worker-service.cjs
+   ```
+   This runs the worker directly without PM2, showing full error output.
+
+2. **Check PM2 itself:**
+   ```bash
+   which pm2
+   pm2 --version
+   ```
+   If PM2 not found, dependencies not installed.
+
+3. **Check dependencies:**
+   ```bash
+   cd ~/.claude/plugins/marketplaces/thedotmack/
+   ls node_modules/@anthropic-ai/claude-agent-sdk
+   ls node_modules/better-sqlite3
+   ls node_modules/express
+   ls node_modules/pm2
+   ```
+
+4. **Check port availability:**
+   ```bash
+   lsof -i :37777
+   ```
+   If port in use, either kill that process or change claude-mem port.
+
+### Common Fixes
+
+**Dependencies missing:**
+```bash
+cd ~/.claude/plugins/marketplaces/thedotmack/
+npm install
+pm2 start ecosystem.config.cjs
+```
+
+**Port conflict:**
+```bash
+echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json
+pm2 restart claude-mem-worker
+```
+
+**Corrupted PM2:**
+```bash
+pm2 kill  # Stop PM2 daemon
+cd ~/.claude/plugins/marketplaces/thedotmack/
+pm2 start ecosystem.config.cjs
+```
+
+## Worker Crashing Repeatedly
+
+If worker keeps restarting (check with `pm2 status` showing high restart count):
+
+### Find the Cause
+
+1. **Check error logs:**
+   ```bash
+   pm2 logs claude-mem-worker --err --lines 100 --nostream
+   ```
+
+2. **Look for crash pattern:**
+   ```bash
+   pm2 logs claude-mem-worker --lines 200 --nostream | grep -A 5 "exited with code"
+   ```
+
+### Common Crash Causes
+
+**Database corruption:**
+```bash
+sqlite3 ~/.claude-mem/claude-mem.db "PRAGMA integrity_check;"
+```
+If fails, backup and recreate database.
+
+**Out of memory:**
+Check if database is too large or memory leak. Restart:
+```bash
+pm2 restart claude-mem-worker
+```
+
+**Port conflict race condition:**
+Another process grabbing port intermittently. Change port:
+```bash
+echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json
+pm2 restart claude-mem-worker
+```
+
+## PM2 Management Commands
+
+```bash
+# List processes
+pm2 list
+pm2 jlist  # JSON format
+
+# Show detailed info
+pm2 show claude-mem-worker
+
+# Monitor resources
+pm2 monit
+
+# Clear logs
+pm2 flush claude-mem-worker
+
+# Restart PM2 daemon
+pm2 kill
+pm2 resurrect  # Restore saved processes
+
+# Save current process list
+pm2 save
+
+# Update PM2
+npm install -g pm2
+```
+
+## Testing Worker Endpoints
+
+Once worker is running, test all endpoints:
+
+```bash
+# Health check
+curl -s http://127.0.0.1:37777/health
+
+# Viewer HTML
+curl -s http://127.0.0.1:37777/ | head -20
+
+# Stats API
+curl -s http://127.0.0.1:37777/api/stats
+
+# Search API
+curl -s "http://127.0.0.1:37777/api/search/observations?q=test&format=index"
+
+# Prompts API
+curl -s "http://127.0.0.1:37777/api/prompts?limit=5"
+```
+
+All should return appropriate responses (HTML for viewer, JSON for APIs).
