- Removed bin/hooks/ wrapper layer
- Moved all hook logic into consolidated hooks/*-hook.ts files
- Each hook now handles its own stdin/stdout/JSON wrapping
- Removed ALL try-catch blocks from context-hook (let errors surface)
- Updated build script to reference new src/hooks/ paths
- Reduced from 12+ files to 6 hook files
This simplifies the architecture and makes debugging actually possible.
Critical bugfix for NOT NULL constraint violation.
Problem:
- Worker service calls getSessionById(sessionDbId) to fetch session data
- Worker then uses dbSession.claude_session_id to create ActiveSession
- But getSessionById was NOT selecting claude_session_id from database
- Result: claudeSessionId = undefined in worker
- Caused: "NOT NULL constraint failed: sdk_sessions.claude_session_id" errors
- Impact: Observations and summaries couldn't be stored
Root cause:
- SessionStore.getSessionById() SQL query missing claude_session_id column
- Line 710-713: "SELECT id, sdk_session_id, project, user_prompt"
- Should be: "SELECT id, claude_session_id, sdk_session_id, project, user_prompt"
Fix:
- Added claude_session_id to SELECT query in getSessionById
- Updated return type to include claude_session_id: string
- Now worker correctly receives claude_session_id from database
- Session ID from hook flows properly through entire system
Files changed:
- src/services/sqlite/SessionStore.ts (getSessionById method)
Testing:
- Build succeeded
- Ready for PM2 restart and live testing

- Added functionality to automatically create a session record in the database if it does not exist when storing observations or session summaries.
- Updated `storeObservation` and `storeSummary` methods to include checks for existing session records and insert new records as needed.
- Added logging for auto-created session records for better traceability.
- Added functionality to save raw user prompts for full-text search in the newHook function.
- Introduced new search endpoint 'search_user_prompts' to retrieve user prompts using FTS5.
- Created UserPromptRow and UserPromptSearchResult types for handling user prompt data.
- Implemented searchUserPrompts method in SessionSearch class to perform FTS5 queries.
- Created user_prompts table with FTS5 support and necessary triggers for data synchronization.
- Updated SessionStore to include methods for saving user prompts and managing the new table.
Root cause: Hooks provide session_id as the source of truth. We were adding
unnecessary validation (checking if sessions exist, checking status, etc.)
which caused 409 conflicts when continuing sessions after /exit.
Changes:
1. worker-service.ts: Removed 409 "Session already exists" check in handleInit
2. SessionStore.ts: Made createSDKSession idempotent using INSERT OR IGNORE
3. new-hook.ts: Simplified to just call createSDKSession - no findActiveSDKSession,
no reactivateSession logic, no status management
4. save-hook.ts: Removed session validation, use fixed port instead of session.worker_port
5. summary-hook.ts: Removed session validation, use fixed port instead of session.worker_port
Philosophy: Hooks manage lifecycle, we just save data with whatever session_id
they give us. No validation, no status checks, no guessing.

Changed summary prompts to generate discrete per-request summaries instead of cumulative session summaries. This provides better chronological memory where each summary is a clean unit representing one request/response cycle.
Changes:
- Renamed buildFinalizePrompt() to buildSummaryPrompt() in src/sdk/prompts.ts
- Updated prompt text to focus on "THIS REQUEST" rather than "this session"
- Updated all import and function call sites in worker-service.ts and worker.ts
- Added IMPORTANT warning to emphasize request-level scope
Expected behavior: Each summary will now describe only what happened during that specific request, eliminating cumulative recaps.

- Updated contextHook to support colorized output for terminal and JSON format for hooks.
- Introduced ANSI color codes for improved readability in terminal output.
- Modified the output structure to include session details with color formatting.
- Added a new method in SessionStore to aggregate files read and modified from observations for a session.
- Improved error handling for JSON parsing of file data in the new method.
Simplified dependency installation by moving from TypeScript runtime bootstrap to bash-based checks in plugin manifest. This reduces complexity and code size while maintaining the same functionality.
Changes:
- Added bash conditional dependency checks to all 5 hooks in hooks.json
- Check runs before each hook: [ ! -d "${CLAUDE_PLUGIN_ROOT}/scripts/node_modules" ] && cd "${CLAUDE_PLUGIN_ROOT}/scripts" && npm install || true
- Reverted all hook TypeScript files to use simple static imports (removed dynamic imports)
- Removed src/shared/bootstrap.ts (44 lines)
- Removed ensureDependencies() calls from all hook entry points
Benefits:
- Simpler architecture using native bash instead of TypeScript
- Net reduction of 157 lines of code
- No runtime overhead when dependencies already installed
- Uses plugin manifest's command hook feature as intended
- Faster and more efficient

Changed all hook entry points to use dynamic imports after bootstrap runs. This ensures that better-sqlite3 is installed before Node.js attempts to resolve the import.
Changes:
- Modified src/bin/hooks/*.ts to call ensureDependencies() before dynamic import
- Moved from static `import { hook } from '...'` to `const { hook } = await import('...')`
- This delays module resolution until after npm install completes
- Bumped version to 4.0.6
The previous approach failed because static imports are resolved at module link time, before any runtime code (including ensureDependencies) executes.

Fixed better-sqlite3 distribution by implementing self-bootstrapping hooks
that auto-install dependencies on first run. This eliminates the need for
users to have native compilation tools or manually install dependencies.
## Solution
Instead of bundling 25MB of better-sqlite3 binaries in git or requiring
manual npm install, hooks now bootstrap themselves on first execution:
1. Created `src/shared/bootstrap.ts` with `ensureDependencies()` function
2. Added bootstrap calls to all hook entry points (context, new, save, summary, cleanup)
3. Created `plugin/scripts/package.json` declaring better-sqlite3 dependency
4. Bootstrap checks if `node_modules` exists, runs `npm install` if missing
5. npm automatically downloads prebuilt better-sqlite3 binary for user's platform
## Changes
**Core Bootstrap System:**
- Added src/shared/bootstrap.ts: Auto-install dependencies using npm
- Modified all hooks (context, new, save, summary, cleanup) to call ensureDependencies()
- Created plugin/scripts/package.json with better-sqlite3 dependency
**Build & Distribution:**
- Removed node_modules copying logic from build script
- Build output is now compact (hooks + package.json, no binaries)
- Updated marketplace.json to point to GitHub for direct installation
**Documentation:**
- Updated README: GitHub Marketplace installation is now recommended method
- Installation instructions emphasize no compilation needed
- Version bumped to 4.0.5 throughout
## Benefits
- ✅ No git bloat (repo stays small, no 25MB binaries committed)
- ✅ No compilation needed (npm downloads prebuilt binaries)
- ✅ Works on all platforms (npm handles platform-specific binaries)
- ✅ Zero manual steps (hooks bootstrap themselves automatically)
- ✅ Idempotent (skips install if dependencies already exist)
Installation now works via simple:
```
/plugin marketplace add https://github.com/thedotmack/claude-mem
/plugin install claude-mem
```

All hooks now call ensureWorkerRunning() BEFORE querying the database. This
ensures the worker's orphaned session cleanup runs before hooks check for
active sessions, preventing 404 errors when hooks try to use sessions that
don't exist in worker memory after a restart.
Hook order now:
1. ensureWorkerRunning() - starts worker, runs cleanup
2. Query DB - cleanup already marked orphaned sessions as failed
3. Use session - only valid sessions are processed
Fixed in:
- new-hook: Line 26, before DB queries
- save-hook: Line 37, before DB queries
- summary-hook: Line 24, before DB queries
- cleanup-hook: Line 50, before DB queries
This prevents the race condition where hooks would read session status before
cleanup ran, then get 404 from worker after cleanup marked sessions failed.
- Removed try-catch blocks in new-hook, save-hook, and summary-hook for cleaner flow.
- Enhanced error handling in save and summary hooks to throw errors instead of logging and returning.
- Introduced ensureWorkerRunning utility to manage worker service lifecycle and health checks.
- Replaced dynamic port allocation with a fixed port for the worker service.
- Simplified path management and removed unused port allocator utility.
- Added database schema initialization for fresh installations and improved migration handling.
BREAKING CHANGES:
- Data directory moved from ~/.claude-mem/ to ${CLAUDE_PLUGIN_ROOT}/data/
- Fresh start required - no migration from v3.x databases
- Worker service now auto-starts on SessionStart hook
New Features:
- MCP Search Server with 6 specialized search tools
- FTS5 full-text search across observations and sessions
- Auto-starting worker service in SessionStart hook
- Citation support for search results (claude-mem:// URIs)
Changes:
- Updated paths.ts to use CLAUDE_PLUGIN_ROOT for data directory
- Added worker auto-start logic to context hook
- Updated worker service to write port file to plugin data dir
- Bumped version to 4.0.0 in package.json and plugin.json
- Created comprehensive CHANGELOG.md documenting v4.0.0 changes
- Updated README.md with v4.0.0 breaking changes and features
- Rebuilt all hooks and worker service
Technical Improvements:
- Improved error handling and graceful degradation
- Structured logging across all components

All 4 hook entry point scripts were missing process.exit(0) after successful
execution, causing Node processes to hang indefinitely instead of returning
control to Claude Code with exit code 0.
Root cause: In commit 6f62a56, process.exit(0) calls were removed from the
hook functions but were never added to the entry point scripts that wrap them.
Fixed files:
- src/bin/hooks/save-hook.ts (PostToolUse)
- src/bin/hooks/new-hook.ts (UserPromptSubmit)
- src/bin/hooks/summary-hook.ts (Stop)
- src/bin/hooks/context-hook.ts (SessionStart)
