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
```

Reverted from GitHub-hosted marketplace to local marketplace file installation method. This allows us to resolve issues with better-sqlite3 native module builds before enabling GitHub marketplace distribution.
Changes:
- Simplified .claude-plugin/marketplace.json (removed metadata, version fields)
- Updated README installation instructions to use local .claude-plugin/marketplace.json
- Bumped version to 4.0.4
Installation now requires cloning the repo and using:
/plugin marketplace add .claude-plugin/marketplace.json
Will restore GitHub marketplace method once native module issues are resolved.

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.
Updates marketplace.json with:
- Marketplace metadata (description, version)
- Plugin version synced to 4.0.2
- Full plugin description from plugin.json
- Author information for discoverability
Users can now install via:
/plugin marketplace add thedotmack/claude-mem
/plugin install claude-mem

The context hook was not appearing in Claude Code sessions because it was
outputting plain text to stdout instead of using the required JSON structure
for SessionStart hooks.
Changes:
- src/hooks/context.ts: Changed contextHook to return string instead of void,
removing direct console.log calls to make it more reusable
- src/bin/hooks/context-hook.ts: Wrap contextHook output in hookSpecificOutput
JSON structure with hookEventName "SessionStart" and additionalContext field
- Both TTY and stdin code paths now properly format and exit with code 0
Fixes the issue where recent session context was not being injected at session
start. Tested with npm run test:context - hook now properly outputs JSON with
recent sessions formatted as markdown.

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)

indefinitely for hook completion.
