# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

## [7.2.3] - 2025-12-15

## Bug Fixes

- **Fix MCP server failures on plugin updates**: Add 2-second pre-restart delay in `ensureWorkerVersionMatches()` to give files time to sync before killing the old worker. This prevents the race condition where the worker restart happened too quickly after plugin file updates, causing "Worker service connection failed" errors.

## Changes

- Add `PRE_RESTART_SETTLE_DELAY` constant (2000ms) to `hook-constants.ts`
- Add delay before `ProcessManager.restart()` call in `worker-utils.ts`
- Fix pre-existing bug where `port` variable was undefined in error logging

**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v7.1.15...v7.2.0

## [7.1.15] - 2025-12-14

## 🐛 Bug Fixes

**Worker Service Initialization**
- Fixed 404 error on `/api/context/inject` during worker startup
- Route is now registered immediately instead of after database initialization
- Prevents race condition on fresh installs and restarts
- Added integration test for early context inject route access

## Technical Details

The context hook was failing with `Cannot GET /api/context/inject` because the route was registered only after database initialization completed. This created a race condition where the hook could attempt to access the endpoint before it existed.

**Implementation:**
- Added `initializationComplete` Promise to track async background initialization
- Register `/api/context/inject` route immediately in `setupRoutes()`
- Early handler blocks requests until initialization resolves (30s timeout)
- Route handler duplicates logic from `SearchRoutes.handleContextInject` by design to prevent 404s

**Testing:**
- Added integration test verifying route registration and timeout handling

Fixes #305

## [7.1.14] - 2025-12-14

## Enhanced Error Handling & Logging

This patch release improves error message quality and logging across the claude-mem system.

### Error Message Improvements

**Standardized Hook Error Handling**
- Created shared error handlers (`handleFetchError`, `handleWorkerError`) for consistent error messages
- Platform-aware restart instructions (macOS, Linux, Windows) with correct commands
- Migrated all hooks (context, new, save, summary) to use standardized handlers
- Enhanced error logging with actionable context before throwing restart instructions

**ChromaSync Error Standardization**
- Consistent client initialization checks across all methods
- Enhanced error messages with troubleshooting steps and restart instructions
- Better context about which operation failed

**Worker Service Improvements**
- Enhanced version endpoint error logging with status codes and response text
- Improved worker restart error messages with PM2 commands
- Better context in all worker-related error scenarios

### Bug Fixes

- **Issue #260**: Fixed `happy_path_error__with_fallback` misuse in save-hook causing false "Missing cwd" errors
- Removed unnecessary `happy_path_error` calls from SDKAgent that were masking real error messages
- Cleaned up migration logging to use `console.log` instead of `console.error` for non-error events

### Logging Improvements

**Timezone-Aware Timestamps**
- Worker logs now use local machine timezone instead of UTC
- Maintains same format (`YYYY-MM-DD HH:MM:SS.mmm`) but reflects local time
- Easier debugging and log correlation with system events
- Enhanced worker-cli logging output format

### Test Coverage

Added comprehensive test suites:
- `tests/error-handling/hook-error-logging.test.ts` - 12 tests for hook error handler behavior

**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v7.1.11...v7.1.12

## [7.1.11] - 2025-12-14

## What's Changed

**Refactor: Simplified hook execution by removing bun-wrapper indirection**

Hooks are compiled to standard JavaScript and work perfectly with Node. The bun-wrapper was solving a problem that doesn't exist - hooks don't use Bun-specific APIs, they're just HTTP clients to the worker service.

**Benefits:**
- Removes ~100 lines of code
- Simpler cross-platform support (especially Windows)
- No PATH resolution needed for hooks
- Worker still uses Bun where performance matters
- Follows YAGNI and Simple First principles

**Fixes:**
- Fish shell compatibility issue (#264)

**Full Changelog:** https://github.com/thedotmack/claude-mem/compare/v7.1.10...v7.1.11

## [7.1.10] - 2025-12-14

## Enhancement

This release adds automatic orphan cleanup to complement the process leak fix from v7.1.9.

### Added

- **Auto-Cleanup on Startup**: Worker now automatically detects and kills orphaned chroma-mcp processes before starting
  - Scans for existing chroma-mcp processes on worker startup
  - Kills all found processes before creating new ones
  - Logs cleanup activity (process count and PIDs)
  - Non-fatal error handling (continues on cleanup failure)

### Benefits

- Automatically recovers from pre-7.1.9 process leaks without manual intervention
- Ensures clean slate on every worker restart
- Prevents accumulation even if v7.1.9's close() method fails
- No user action required - works transparently

### Example Logs

```
[INFO] [SYSTEM] Cleaning up orphaned chroma-mcp processes {count=2, pids=33753,33750}
[INFO] [SYSTEM] Orphaned processes cleaned up {count=2}
```

### Recommendation

Upgrade from v7.1.9 to get automatic orphan cleanup. Combined with v7.1.9's proper subprocess cleanup, this provides comprehensive protection against process leaks.

**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v7.1.9...v7.1.10

## [7.1.9] - 2025-12-14

## Critical Bugfix

This patch release fixes a critical memory leak that caused chroma-mcp processes to accumulate with each worker restart, leading to memory exhaustion and silent backfill failures.

### Fixed

- **Process Leak Prevention**: ChromaSync now properly cleans up chroma-mcp subprocesses when the worker is restarted
  - Store reference to StdioClientTransport subprocess
  - Explicitly close transport to kill subprocess on shutdown
  - Add error handling to ensure cleanup even on failures
  - Reset all state in finally block

### Impact

- Eliminates process accumulation (16+ orphaned processes seen in production)
- Prevents memory exhaustion from leaked subprocesses (900MB+ RAM usage)
- Fixes silent backfill failures caused by OOM kills
- Ensures graceful cleanup on worker shutdown

### Recommendation

**All users should upgrade immediately** to prevent memory leaks and ensure reliable backfill operation.

- Complete documentation in docs/public/usage/export-import.mdx

### Use Cases
- Share memory sets between developers working on the same project
- Backup and restore specific project memories
- Collaborate on domain knowledge across teams
- Migrate memories between different claude-mem installations

### Example Usage
```bash
# Export Windows-related memories
npx tsx scripts/export-memories.ts "windows" windows-work.json

# Export only claude-mem project memories
npx tsx scripts/export-memories.ts "bugfix" fixes.json --project=claude-mem

# Import memories (with automatic duplicate prevention)
npx tsx scripts/import-memories.ts windows-work.json
```

### Technical Improvements
- Fixed JSON format response in /api/search endpoint for consistent structure
- Enhanced project filtering in ChromaDB hybrid search result hydration
- Duplicate detection using composite keys (session ID + title + timestamp)

## [7.1.7] - 2025-12-13

## Fixed
- Removed Windows workaround that was causing libuv assertion failures
- Prioritized stability over cosmetic console window issue

## Known Issue

**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v7.1.3...v7.1.4

## [7.1.3] - 2025-12-13

## Bug Fixes

### Smart Install Script Refactoring

Refactored the smart-install.js script to improve code quality and maintainability:
- Extracted common installation paths as top-level constants (BUN_COMMON_PATHS, UV_COMMON_PATHS)
- Simplified installation check functions to delegate to dedicated path-finding helpers
- Streamlined installation verification logic with clearer error messages
- Removed redundant post-installation verification checks
- Improved error propagation by removing unnecessary retry logic

This refactoring reduces code duplication and makes the installation process more maintainable while preserving the same functionality for detecting Bun and uv binaries across platforms.

## [7.1.2] - 2025-12-13

## 🐛 Bug Fixes

### Windows Installation
- Fixed Bun PATH detection on Windows after fresh install
- Added fallback to check common install paths before PATH reload  
- Improved smart-install.js to use full Bun path when not in PATH
- Added proper path quoting for Windows usernames with spaces

### Worker Startup
- Fixed worker connection failures in Stop hook
- Added health check retry loop (5 attempts, 500ms intervals)
- Worker now waits up to 2.5s for responsiveness before returning
- Improved error detection for Bun's ConnectionRefused error format

**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v7.1.1...v7.1.2

## [7.1.1] - 2025-12-13

## 🚨 Critical Fixes

### Windows 11 Bun Auto-Install Fixed
- **Problem**: v7.1.0 had a chicken-and-egg bug where `bun smart-install.js` failed if Bun wasn't installed
- **Solution**: SessionStart hook now uses `node` (always available) for smart-install.js
- **Impact**: Fresh Windows installations now work out-of-box

### Path Quoting for Windows
- Fixed `hooks.json` to quote all paths
- Prevents SyntaxError for usernames with spaces (e.g., "C:\Users\John Doe\")

## ✨ New Feature

### Automatic Worker Restart on Version Updates
- Worker now automatically restarts when plugin version changes
- No more manual `npm run worker:restart` needed after upgrades
- Eliminates connection errors from running old worker code

## 📝 Notes

- **No manual actions required** - worker auto-restarts on next session start
- All future upgrades will automatically restart the worker
- Fresh installs on Windows 11 work correctly

## [7.1.0] - 2025-12-13

## Major Architectural Migration

This release completely replaces PM2 with native Bun-based process management and migrates from better-sqlite3 to bun:sqlite.

### Key Changes

**Process Management**
- Replace PM2 with custom Bun-based ProcessManager
- PID file-based process tracking
- Automatic legacy PM2 process cleanup on all platforms

**Database Driver**
- Migrate from better-sqlite3 npm package to bun:sqlite runtime module
- Zero native compilation required
- Same API compatibility

**Auto-Installation**
- Bun runtime auto-installed if missing
- uv (Python package manager) auto-installed for Chroma vector search
- Smart installer with platform-specific methods (curl/PowerShell)

### Migration

**Automatic**: First hook trigger after update performs one-time PM2 cleanup and transitions to new architecture. No user action required.

### Documentation

Complete technical documentation in `docs/PM2-TO-BUN-MIGRATION.md`

## [7.0.11] - 2025-12-12

Patch release adding feature/bun-executable to experimental branch selector for testing Bun runtime integration.

## [7.0.9] - 2025-12-10

## Bug Fixes

- Fixed MCP response format in search route handlers - all 14 search endpoints now return complete response objects with error status instead of just content arrays, restoring MCP protocol compatibility

## Changes

- `SearchRoutes.ts`: Updated all route handlers to return full result object instead of extracted content property

## [7.0.8] - 2025-12-10

## Bug Fixes

- **Critical**: Filter out meta-observations for session-memory files to prevent recursive timeline pollution
  - Memory agent was creating observations about editing Agent SDK's session-memory/summary.md files
  - This created a recursive loop where investigating timeline pollution caused more pollution
  - Filter now skips Edit/Write/Read/NotebookEdit operations on any file path containing 'session-memory'
  - Eliminates 91+ meta-observations that were polluting the timeline

## Technical Details

Added filtering logic in SessionRoutes.ts to detect and skip file operations on session-memory files before observations are queued to the SDK agent. This prevents the memory agent from observing its own observation metadata files.

## [7.0.7] - 2025-12-10

## What's Changed

### Code Quality Improvements
- Refactored hooks codebase to reduce complexity and improve maintainability (#204)
- Net reduction of 78 lines while adding new functionality
- Improved type safety across all hook input interfaces

### New Features
- Added `CLAUDE_MEM_SKIP_TOOLS` configuration setting for controlling which tools are excluded from observations
- Default skip tools: `ListMcpResourcesTool`, `SlashCommand`, `Skill`, `TodoWrite`, `AskUserQuestion`

### Technical Improvements
- Created shared utilities: `transcript-parser.ts`, `hook-constants.ts`, `hook-error-handler.ts`
- Migrated business logic from hooks to worker service for better separation of concerns
- Enhanced error handling and spinner management
- Removed dead code and unnecessary abstractions

## Bug Fixes

- **Hook Execution**: Ensure worker is running at the beginning of all hook files
- **Context Hook**: Replace waitForPort with ensureWorkerRunning for better error handling
- **Reliability**: Move ensureWorkerRunning to start of all hook functions to ensure worker is started before any logic executes

## Technical Changes

- context-hook.ts: Replace waitForPort logic with ensureWorkerRunning
- summary-hook.ts: Move ensureWorkerRunning before input validation
- new-hook.ts: Move ensureWorkerRunning before debug logging
- save-hook.ts: Move ensureWorkerRunning before SKIP_TOOLS check

- `SearchManager` - Extracted search logic from context generation

### Database Improvements
- Migrated from \`bun:sqlite\` to \`better-sqlite3\` for broader compatibility
- SQL queries moved from route handlers to \`SessionStore\` for separation of concerns
- \`PaginationHelper\` centralizes paginated queries with LIMIT+1 optimization

### Testing Infrastructure
- New comprehensive happy path tests for full session lifecycle
- Integration tests covering session init, observation capture, search, summaries, cleanup
- Test helpers and mocks for consistent testing patterns

### Type Safety
- Removed 'as any' casts throughout codebase
- New \`src/types/database.ts\` with proper type definitions
- Enhanced null safety in SearchManager

## Stats
- **60 files changed**
- **8,671 insertions, 5,585 deletions**
- Net: ~3,000 lines of new code (mostly tests and new modular services)

## Migration Notes

No migration required! Update and continue using claude-mem as before.

- **`<private>` tags**: User-level privacy control - wrap any sensitive content to prevent storage in observation history
- **`<claude-mem-context>` tags**: System-level tags for auto-injected observations to prevent recursive storage
- Tag stripping happens at the hook layer (edge processing) before data reaches worker/database
- Comprehensive documentation in `docs/public/usage/private-tags.mdx`

### User Experience
- New inline help message in context hook highlighting the `<private>` tag feature
- Improved Community link formatting in startup messages

## 🔧 Improvements

### Search API
- Simplified search endpoint parameters to eliminate bracket encoding issues (#154)
- Cleaner API interface for mem-search skill

### Performance
- Added composite index for user prompts lookup optimization
- Shared tag-stripping utilities in `src/utils/tag-stripping.ts`

## 📚 Documentation

- Updated CLAUDE.md with Privacy Tags section
- Enhanced private-tags.mdx with implementation details
- Added comprehensive test coverage for tag stripping

## 🔗 Related PRs

## [6.3.7] - 2025-12-01

## Bug Fixes

- **fix: Remove orphaned closing brace in smart-install.js** - Fixes SyntaxError "Missing catch or finally after try" that was preventing the plugin from loading correctly

## What Changed

Fixed a syntax error in `scripts/smart-install.js` where an extra closing brace on line 392 caused the SessionStart hook to fail. The PM2 worker startup try/catch block was properly formed but had an orphaned closing brace that didn't match any opening brace.

This bug was introduced in a recent release and prevented the plugin from loading correctly for users.

## [6.3.6] - 2025-11-30

## Auto-detect and rebuild native modules on Node.js version changes

### Bug Fixes
- **Native Module Compatibility**: Auto-detects Node.js version changes and rebuilds better-sqlite3 when needed
- **Self-healing Recovery**: Gracefully handles ERR_DLOPEN_FAILED errors with automatic reinstall on next session
- **Version Tracking**: Enhanced .install-version marker now tracks both package and Node.js versions (JSON format)
- **Runtime Verification**: Added verifyNativeModules() to catch ABI mismatches and corrupted builds

### Technical Details
This release fixes a critical issue where upgrading Node.js (e.g., v22 → v25) would cause native module failures that the plugin couldn't auto-recover from. The smart-install script now:
- Tracks Node.js version in addition to package version
- Verifies native modules actually load (not just file existence)
- Triggers rebuild when either version changes
- Handles runtime failures gracefully with helpful user messaging

### Contributors
- @dreamiurg - Thank you for the comprehensive fix and thorough testing!

### Merged PRs
- #149 - feat: Auto-detect and rebuild native modules on Node.js version changes

- Sidebar toggles via hamburger menu on mobile
- Both buttons positioned in header for consistent UX

Full changelog: https://github.com/thedotmack/claude-mem/compare/v6.3.4...v6.3.5

## [6.3.4] - 2025-11-30

## Bug Fixes

### Worker Startup Improvements

Fixed critical issues with worker service startup on fresh installations:

- **Auto-start worker after installation** - The PM2 worker now starts automatically during plugin installation
- **Local PM2 resolution** - Plugin now uses local PM2 from node_modules/.bin instead of requiring global installation
- **Improved error messages** - Clear, actionable instructions with full paths when worker fails to start
- **Cross-platform support** - Proper handling of Windows platform differences (pm2.cmd)
- **Security enhancement** - Switched from execSync to spawnSync with array arguments to prevent command injection

These changes significantly improve the first-time installation experience, eliminating the need for manual PM2 setup.

**Special thanks to @dreamiurg for identifying and fixing this critical UX issue!** 🙏

## [6.2.1] - 2025-11-23

## 🐛 Bug Fixes

### Critical: Empty Project Names Breaking Context Injection

**Problem:**
- Observations and summaries created with empty project names
- Context-hook couldn't find recent context (queries `WHERE project = 'claude-mem'`)
- Users saw no observations or summaries in SessionStart since Nov 22

**Root Causes:**

1. **Sessions:** `createSDKSession()` used `INSERT OR IGNORE` for idempotency, but never updated project field when session already existed
2. **In-Memory Cache:** `SessionManager` cached sessions with stale empty project values, even after database was updated

**Fixes:**

- `5d23c60` - fix: Update project name when session already exists in createSDKSession
- `54ef149` - fix: Refresh in-memory session project when updated in database

**Impact:**
- ✅ 364 observations backfilled with correct project names
- ✅ 13 summaries backfilled with correct project names  
- ✅ Context injection now works (shows recent observations and summaries)
- ✅ Future sessions will always have correct project names

## 📦 Full Changelog

**Commits since v6.2.0:**
- `634033b` - chore: Bump version to 6.2.1
- `54ef149` - fix: Refresh in-memory session project when updated in database
- `5d23c60` - fix: Update project name when session already exists in createSDKSession

## [6.2.0] - 2025-11-22

## Major Features

### Unified Search API (#145, #133)
- **Vector-first search architecture**: All text queries now use ChromaDB semantic search
- **Unified /api/search endpoint**: Single endpoint with filter parameters (type, concepts, files)
- **ID-based fetch endpoints**: New GET /api/observation/:id, /api/session/:id, /api/prompt/:id
- **90-day recency filter**: Automatic relevance filtering for search results
- **Backward compatibility**: Legacy endpoints still functional, routing through unified infrastructure

### Search Architecture Cleanup
- **Removed FTS5 fallback code**: Eliminated ~300 lines of deprecated full-text search code
- **Removed experimental contextualize endpoint**: Will be reimplemented as LLM-powered skill (see #132)
- **Simplified mem-search skill**: Streamlined to prescriptive 3-step workflow (Search → Review IDs → Fetch by ID)
- **Better error messages**: Clear guidance when ChromaDB/UVX unavailable

## Bug Fixes

## [6.0.8] - 2025-11-17

## Critical Fix

This patch release fixes a critical bug where the PM2 worker process would start from the wrong directory (development folder instead of marketplace folder), causing the plugin to malfunction when installed via the marketplace.

### What's Fixed

- **Worker Startup Path Resolution** (`src/shared/worker-utils.ts:61`)  
  Added `cwd: pluginRoot` option to `execSync` when starting PM2
  
  This ensures the worker always starts from the correct marketplace directory (`~/.claude/plugins/marketplaces/thedotmack/`), regardless of where the hook is invoked from.

### Impact

Users will no longer experience issues with the worker starting from the wrong location. The plugin now works correctly when installed via marketplace without manual intervention.

### Verification

Run `pm2 info claude-mem-worker` to verify:
- **exec cwd** should be: `/Users/[username]/.claude/plugins/marketplaces/thedotmack`
- **script path** should be: `/Users/[username]/.claude/plugins/marketplaces/thedotmack/plugin/scripts/worker-service.cjs`

## [6.0.7] - 2025-11-17

## Critical Hotfix: Database Migration Issue (#121)

This is an emergency hotfix addressing a critical database migration bug that prevented claude-mem from loading for some users.

### What was fixed

**Issue**: Users were seeing `SqliteError: no such column: discovery_tokens` when starting Claude Code.

**Root Cause**: The `ensureDiscoveryTokensColumn` migration was using version number 7, which was already taken by another migration (`removeSessionSummariesUniqueConstraint`). This duplicate version number caused migration tracking issues in databases that were upgraded through multiple versions.

**Fix**: 
- Changed migration version from 7 to 11 (next available)
- Added explicit schema_versions check to prevent unnecessary re-runs
- Improved error propagation and documentation

### Upgrade Instructions

**If you're experiencing the error:**

Option 1 - Manual fix (preserves history):
```bash
sqlite3 ~/.claude-mem/claude-mem.db "ALTER TABLE observations ADD COLUMN discovery_tokens INTEGER DEFAULT 0; ALTER TABLE session_summaries ADD COLUMN discovery_tokens INTEGER DEFAULT 0;"
```

Option 2 - Delete and recreate (loses history):
```bash
rm ~/.claude-mem/claude-mem.db
# Restart Claude Code - database will recreate with correct schema
```

Option 3 - Fresh install:
Just upgrade to v6.0.7 and the migration will work correctly.

### Changes

- **Fixed**: Database migration version conflict (migration 7 → 11) (#121)
- **Improved**: Migration error handling and schema_versions tracking

### Full Changelog

See [CHANGELOG.md](https://github.com/thedotmack/claude-mem/blob/main/CHANGELOG.md) for complete version history.

**Affected Users**: @liadtigloo @notmyself - this release fixes your reported issue. Please try one of the upgrade options above and let me know if the issue persists.

Thanks to everyone who reported this issue with detailed error logs! 🙏

## [6.0.6] - 2025-11-17

## Critical Bugfix Release

  - src/services/worker/SDKAgent.ts (pass through last user message to SDK)
- Built outputs updated:
  - plugin/scripts/summary-hook.js
  - plugin/scripts/worker-service.cjs

**What Changed**:
The summary hook now reads Claude Code transcript files to extract the last user message before generating session summaries. This provides better context for AI-powered session summarization. The activity indicator now accurately reflects both active sessions and queued work, giving users better feedback about what's happening behind the scenes.

## [5.5.0] - 2025-11-11

**Breaking Changes**: None (minor version)

**Improvements**:
- Merged PR #91: Replace generic "search" skill with enhanced "mem-search" skill
- Improved skill effectiveness from 67% to 100% (Anthropic standards)
- Enhanced scope differentiation to prevent confusion with native conversation memory
- Increased concrete triggers from 44% to 85%

## [5.4.5] - 2025-11-11

**Patch Release**: Bugfixes and minor improvements

## [5.4.4] - 2025-11-10

**Breaking Changes**: None (patch version)

**Bugfix**:
- Fixed duplicate observations and summaries appearing in viewer with different IDs and timestamps
- Root cause: `handleSessionInit` spawned an SDK agent but didn't save the promise to `session.generatorPromise`, causing `handleObservations` to spawn a second agent for the same session

**Technical Details**:
- Modified: src/services/worker-service.ts:265
- Change: Now assigns `session.generatorPromise = this.sdkAgent.startSession(...)` to track the promise
- Impact: Single SDK agent per session (previously two), eliminates duplicate database entries and SSE broadcasts
- Pattern: Matches existing implementation in `handleSummarize` (line 332)
- Guard: Leverages existing condition in `handleObservations` (line 301) that checks for existing promise

**User Impact**:
- No more duplicate entries in the viewer UI
- Cleaner, more accurate memory stream visualization
- Reduced redundant processing and database writes

Merged via PR #86

## [5.4.3] - 2025-11-10

**Breaking Changes**: None (patch version)

**Bug Fixes**:
- Fixed PM2 race condition between watch mode and PostToolUse hook
- Eliminated `TypeError: Cannot read properties of undefined (reading 'pm2_env')` errors
- Reduced unnecessary worker restarts (39+ restarts → minimal)

**Technical Details**:
- Removed PM2 restart logic from `ensureWorkerRunning()` in `src/shared/worker-utils.ts`
- PM2 watch mode now exclusively handles worker restarts on file changes
- Function now only checks worker health via HTTP endpoint and provides clear error messaging
- Removed unused imports and helper functions (`execSync`, `getPackageRoot`, `waitForWorkerHealth`)

**Files Modified**:
- `src/shared/worker-utils.ts` (40 deletions, 14 additions)
- All built hooks and worker service (rebuilt from source)

**Impact**: This fix eliminates error spam in hook output while maintaining full functionality. Users will see cleaner output and fewer unnecessary restarts.

**Upgrade Notes**: No action required. PM2 watch mode will automatically restart the worker on plugin updates.

## [5.4.2] - 2025-11-10

**Bugfix Release**: CWD spatial awareness for SDK agent

### What's Fixed

- **CWD Context Propagation**: SDK agent now receives current working directory (CWD) context from tool executions
- **Spatial Awareness**: Prevents false "file not found" reports when working across multiple repositories
- **Observer Guidance**: Agent prompts now include tool_cwd XML elements with spatial awareness instructions

### Technical Details

**Data Flow**:
1. Hook extracts CWD from PostToolUseInput (`hookInput.result.tool_cwd`)
2. Worker service receives CWD in PendingMessage and ObservationData interfaces
3. SessionManager passes CWD to SDKAgent's addObservation method
4. SDK agent includes CWD in tool observation objects sent to Claude API
5. Prompts conditionally render tool_cwd XML with spatial awareness guidance

**Implementation**:
- Optional CWD fields throughout for backward compatibility
- Defaults to empty string when CWD is missing
- CWD treated as read-only display context, not for file operations
- Complete propagation chain from hook → worker → SDK → prompts

**Test Coverage**:
- 8 comprehensive tests validating CWD propagation
- Tests cover hook extraction, worker forwarding, SDK inclusion, and prompt rendering
- All tests pass with tsx TypeScript loader

**Security**:
- Zero vulnerabilities introduced
- CodeQL analysis: No alerts
- Read-only context display (no file operation changes)
- Input validation and sanitization maintained

### Files Changed

**Source Files**:
- `src/hooks/save-hook.ts` - Extract CWD from PostToolUseInput
- `src/services/worker-types.ts` - Add optional CWD fields to interfaces
- `src/services/worker-service.ts` - Forward CWD in message handling
- `src/services/worker/SessionManager.ts` - Pass CWD to SDK agent
- `src/services/worker/SDKAgent.ts` - Include CWD in tool observations
- `src/sdk/prompts.ts` - Render tool_cwd XML with spatial guidance

**Built Artifacts**:
- `plugin/scripts/save-hook.js` - Compiled hook with CWD extraction
- `plugin/scripts/worker-service.cjs` - Compiled worker with CWD handling

**Tests & Documentation**:
- `tests/cwd-propagation.test.ts` - Comprehensive test suite (8 tests)
- `context/CWD_CONTEXT_FIX.md` - Technical implementation documentation
- `PR_SUMMARY.md` - Pull request summary and rationale
- `SECURITY_SUMMARY.md` - Security analysis and review
- `CHANGELOG.md` - Version history entry

### Installation

```bash
# Update to latest version
/plugin update claude-mem
```

Or restart Claude Code to auto-update.

### Upgrade Notes

- **Backward Compatible**: No breaking changes
- **No Action Required**: CWD propagation works automatically
- **Existing Sessions**: Will benefit from improved spatial awareness

**Breaking Changes**: None (patch version)

**New Features**:
- Added REST API endpoints for MCP server status and toggle control
- Implemented UI toggle in viewer sidebar for enabling/disabling MCP search server
- File-based persistence mechanism (.mcp.json ↔ .mcp.json.disabled)
- Independent state management for MCP toggle

**Technical Details**:
- New endpoints:
  - GET /api/mcp/status (returns mcpEnabled boolean)
  - POST /api/mcp/toggle (toggles MCP server state)
- Modified files:
  - src/services/worker-service.ts (added MCP control logic)
  - src/ui/viewer/components/Sidebar.tsx (added MCP toggle UI)
  - plugin/.mcp.json (MCP server configuration)
- Design rationale: Provides runtime control of the MCP search server to allow users to disable it when not needed, reducing resource usage. The file-based toggle mechanism ensures persistence across worker restarts.

**Known Issues**: None

**Upgrade Notes**: No breaking changes. Upgrade by running standard update process.

## [5.4.0] - 2025-11-10

### ⚠️ BREAKING CHANGE: MCP Search Tools Removed

**Migration**: None required. Claude automatically uses the search skill when needed.

### 🔍 Major Feature: Skill-Based Search Architecture

**Token Savings**: ~2,250 tokens per session start (90% reduction)

**What Changed:**
- **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)
- **User Experience**: Identical - just ask naturally about past work

### ✨ Improvements

**Progressive Disclosure Pattern:**
- Skill frontmatter (~250 tokens) loads at session start
- Full instructions (~2,500 tokens) load only when skill is invoked
- HTTP API endpoints replace MCP protocol
- No user action required - migration is transparent

**Natural Language Queries:**
```
"What bugs did we fix last session?"
"How did we implement authentication?"
"What changes were made to worker-service.ts?"
"Show me recent work on this project"
```

### 🆕 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
- `GET /api/search/help` - API documentation

**Search Skill** (`plugin/skills/search/SKILL.md`):
- Auto-invoked when users ask about past work, decisions, or history
- Comprehensive documentation with usage examples and workflows
- Format guidelines for presenting search results
- 12 operation files with detailed instructions

### 🗑️ Removed

**MCP Search Server** (deprecated):
- Removed `claude-mem-search` from plugin/.mcp.json
- Build script no longer compiles search-server.mjs
- Source file kept for reference: src/servers/search-server.ts
- All 9 MCP tools replaced by equivalent HTTP API endpoints

### 📚 Documentation

**Comprehensive Updates:**
- `README.md`: Updated version badge, What's New, and search section
- `docs/usage/search-tools.mdx`: Complete rewrite for skill-based approach
- `docs/architecture/mcp-search.mdx` → `search-architecture.mdx`: New architecture doc
- `docs/architecture/overview.mdx`: Updated components and search pipeline
- `docs/usage/getting-started.mdx`: Added skill-based search section
- `docs/configuration.mdx`: Updated search configuration
- `docs/introduction.mdx`: Updated key features

### 🔧 Technical Details

**How It Works:**
1. User asks: "What did we do last session?"
2. Claude recognizes intent → invokes search skill
3. Skill loads full instructions from `SKILL.md`
4. Skill uses `curl` to call HTTP API endpoint
5. Results formatted and returned to Claude
6. Claude presents results to user

**Benefits:**
- **Token Efficient**: Only loads what you need, when you need it
- **Natural**: No syntax to learn, just ask questions
- **Progressive**: Start with overview, drill down as needed
- **Flexible**: HTTP API can be called from skills, MCP tools, or other clients

### 🐛 Migration Notes

**For Users:**
- ✅ No action required - migration is transparent
- ✅ Same questions work - natural language queries identical
- ✅ Invisible change - only notice better performance

**For Developers:**
- ⚠️ MCP search server deprecated (source kept for reference)
- ✅ New implementation: Skill files + HTTP endpoints
- ✅ Build/sync workflow unchanged

**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v5.3.0...v5.4.0

## [5.3.0] - 2025-11-09

**Breaking Changes**: None (minor version)

**Session Lifecycle Improvements**:
- **Prompt Counter Restoration**: SessionManager now loads prompt counter from database on worker restart, preventing state loss
- **Continuation Prompts**: Lightweight prompts for request #2+ avoid re-initializing SDK agent's mental model
- **Summary Framing**: Changed from "final report" to "progress checkpoint" to clarify mid-session summaries

**Bug Fixes**:
- **#76**: Fixed PM2 "Process 0 not found" error by using idempotent `pm2 start` instead of `pm2 restart`
- **#74, #75**: Fixed troubleshooting skill distribution by moving to `plugin/skills/` directory
- **#73 (Partial)**: Improved context-loading task reporting in summaries

**Technical Details**:
- Modified files:
  - `src/services/worker/SessionManager.ts` (loads prompt_counter from DB)
  - `src/services/worker/SDKAgent.ts` (uses continuation prompts)
  - `src/sdk/prompts.ts` (added buildContinuationPrompt function)
  - `src/shared/worker-utils.ts` (pm2 start instead of restart)
  - `src/hooks/context-hook.ts` (improved context loading)
  - Moved `.claude/skills/troubleshoot` → `plugin/skills/troubleshoot`

**Why These Changes Matter**:
- Worker restarts no longer lose session state
- Subsequent prompts are more efficient (no re-initialization overhead)
- Summaries better reflect ongoing work vs completed sessions
- PM2 errors eliminated for new users
- Troubleshooting skill now properly distributed to plugin users

**Upgrade Notes**: No breaking changes. Worker will automatically pick up improvements on restart.

## [5.2.3] - 2025-11-09

**Breaking Changes**: None (patch version)

**Improvements**:
- Added troubleshooting slash command skill for diagnosing claude-mem installation issues
- Comprehensive diagnostic workflow covering PM2, worker health, database, dependencies, logs, and viewer UI
- Automated fix sequences and common issue resolutions
- Full system diagnostic report generation

**Technical Details**:
- New file: `.claude/skills/troubleshoot/SKILL.md` (363 lines)
- Added troubleshooting skill documentation to `README.md` and `docs/troubleshooting.mdx`
- Version bumped to 5.2.3 across all metadata files

**Usage**:
Run `/skill troubleshoot` or invoke the `troubleshoot` skill to diagnose claude-mem issues.

The skill provides systematic checks for:
- PM2 worker status
- Worker service health
- Database state and integrity
- Dependencies installation
- Worker logs
- Viewer UI endpoints
- Full system diagnostic report

## [5.2.2] - 2025-11-08

**Breaking Changes**: None (patch version)

**Improvements**:
- Context hook now displays 'investigated' and 'learned' fields from session summaries
- Enhanced startup context visibility with color-coded formatting (blue for investigated, yellow for learned)
- Improved session summary detail display at startup

**Technical Details**:
- Modified files:
  - src/hooks/context-hook.ts (enhanced SQL query and display logic)
  - plugin/scripts/context-hook.js (built hook with new functionality)
- Updated SQL query to SELECT investigated and learned columns
- Added TypeScript type definitions for nullable investigated and learned fields
- Added conditional display blocks with appropriate color formatting

**Impact**: Users will now see more comprehensive session summary information at startup, providing better context about what was investigated and learned in previous sessions.

## [5.2.1] - 2025-11-08

**Breaking Changes**: None (patch version)

### Bug Fixes

This patch release fixes critical race conditions and state synchronization issues in the viewer UI's project filtering system.

**Fixed Issues:**
- **Race condition with offset reset**: When filter changed, offset wasn't reset synchronously, causing incorrect pagination ranges (e.g., loading items 20-40 for new project with < 20 items)
- **State ref synchronization**: `stateRef.current.hasMore` retained old value when filter changed, preventing new filter from loading if previous filter had no more data
- **Data mixing between projects**: Batched state updates caused data from different projects to appear together in the UI
- **useEffect dependency cycle**: `handleLoadMore` in dependencies caused double renders when filter changed
- **NULL projects in dropdown**: Empty/NULL project values appeared in the project filter dropdown

**Technical Improvements:**
- Combined two separate useEffect hooks into one for guaranteed execution order (reset → load)
- Removed redundant filter change detection logic (DRY principle)
- Simplified validation in `mergeAndDeduplicateByProject` function
- Added `investigated` field to Summary interface for better session tracking

**Files Changed:**
- `src/ui/viewer/App.tsx` - Fixed filter change detection and data reset logic
- `src/ui/viewer/hooks/usePagination.ts` - Improved offset and state ref handling
- `src/ui/viewer/utils/data.ts` - Simplified validation logic
- `src/services/sqlite/SessionStore.ts` - Filter NULL/empty projects from dropdown
- `src/ui/viewer/types.ts` - Added investigated field to Summary interface
- `src/ui/viewer/components/SummaryCard.tsx` - Display investigated field

All changes follow CLAUDE.md coding standards: DRY, YAGNI, and fail-fast error handling.

### Testing

Verified fixes work correctly:
1. ✅ Select project from dropdown → Data loads immediately
2. ✅ Switch between multiple projects → Only selected project's data shown (no mixing)
3. ✅ Rapid switching between projects → No race conditions or stale data
4. ✅ Switch back to "All Projects" → All data appears correctly with SSE updates

## [5.2.0] - 2025-11-07

This release delivers a comprehensive architectural refactor of the worker service, extensive UI enhancements, and significant code cleanup. Merges PR #69.

## 📖 Related

- **PR**: #69
- **Previous Version**: 5.1.4
- **Semantic Version**: MINOR (backward compatible features & improvements)

## [5.1.4] - 2025-11-07

**Bugfix Release**: PostToolUse Hook Schema Compliance

**Changes**:
- Fixed parameter naming in save-hook to match Claude Code PostToolUse API schema
- Renamed `tool_output` to `tool_response` throughout the codebase
- Updated worker-service to handle `tool_response` field correctly

**Technical Details**:
- Modified files:
  - `src/hooks/save-hook.ts`: Updated interface and parameter destructuring
  - `src/services/worker-service.ts`: Updated observation message handling
  - `plugin/scripts/save-hook.js`: Rebuilt with corrected names
  - `plugin/scripts/worker-service.cjs`: Rebuilt with corrected names

**Why This Matters**: The Claude Code PostToolUse hook API provides `tool_response` not `tool_output`. This fix ensures proper schema compliance and prevents potential errors when capturing tool executions.

**Breaking Changes**: None (backward compatible MINOR version)

**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v5.0.3...v5.1.0

## [5.0.3] - 2025-11-05

**Breaking Changes**: None (patch version)

**Fixes**:
- Fixed Windows installation with smart caching installer (PR #54: scripts/smart-install.js)
- Eliminated redundant npm install executions on every SessionStart (improved from 2-5s to ~10ms)
- Added comprehensive Windows troubleshooting with VS Build Tools guidance
- Fixed dynamic Python version detection in Windows error messages (scripts/smart-install.js:106-115)

**Improvements**:
- Smart install now caches version state in `.install-version` file
- Only runs npm install when needed: first time, version change, or missing dependencies
- Enhanced rsync to respect gitignore rules in sync-marketplace (package.json:38)
- Better PM2 worker startup verification and management
- Cross-platform compatible installer (pure Node.js, no shell dependencies)

**Technical Details**:
- New: scripts/smart-install.js (smart caching installer with PM2 worker management)
- Modified: plugin/hooks/hooks.json:25 (use smart-install.js instead of raw npm install)
- Modified: .gitignore (added .install-version cache file)
- Modified: CLAUDE.md (added Windows requirements and troubleshooting section)
- Modified: package.json:38 (enhanced sync-marketplace with --filter=':- .gitignore' --exclude=.git)
- Root cause: npm install was running on every SessionStart regardless of whether dependencies changed
- Impact: 200x faster SessionStart for cached installations (10ms vs 2-5s)

**For Windows Users**:
This release should completely resolve installation issues. The smart installer will:
1. Show you clear error messages if better-sqlite3 fails to install
2. Guide you to install VS Build Tools if needed (though you probably won't need them)
3. Only run once on first launch, then be instant on subsequent launches

## [5.0.2] - 2025-11-05

**Breaking Changes**: None (patch version)

**Fixes**:
- Fixed worker startup reliability with async health checks (PR #51: src/shared/worker-utils.ts)
- Added proper error handling to PM2 process spawning (src/shared/worker-utils.ts)
- Worker now verifies health before proceeding with hook operations
- Improved handling of PM2 failures when not yet installed

**Technical Details**:
- Modified: src/shared/worker-utils.ts (added isWorkerHealthy, waitForWorkerHealth functions)
- Modified: src/hooks/*.ts (all hooks now await ensureWorkerRunning)
- Modified: plugin/scripts/*.js (rebuilt hook executables)
- Root cause: ensureWorkerRunning was synchronous and didn't verify worker was actually responsive before proceeding
- Impact: More reliable worker startup with proper health verification

## [5.0.0] - 2025-11-04

### BREAKING CHANGES
- **Python dependency for optimal performance**: While the plugin works without Python, installing Python 3.8+ and the Chroma MCP server unlocks semantic search capabilities. Without Python, the system falls back to SQLite FTS5 keyword search.
- **Search behavior changes**: Search queries now prioritize semantic relevance when Chroma is available, then apply temporal ordering. Keyword-only queries may return different results than v4.x.
- **Worker service changes**: Worker now initializes ChromaSync on startup. If Chroma MCP is unavailable, worker continues with FTS5-only mode but logs a warning.

### Added
- **Hybrid Search Architecture**: Combines ChromaDB semantic search with SQLite temporal/metadata filtering
  - Chroma vector database for semantic similarity (top 100 matches)
  - 90-day temporal recency window for relevant results
  - SQLite hydration in chronological order
  - Graceful fallback to FTS5 when Chroma unavailable
- **ChromaSync Service**: Automatic vector database synchronization
  - Syncs observations, session summaries, and user prompts to Chroma
  - Splits large text fields into multiple vectors for better granularity
  - Maintains metadata for filtering (project, type, concepts, files)
  - Background sync process via worker service
- **get_timeline_by_query Tool**: Natural language timeline search with dual modes
  - Auto mode: Automatically uses top search result as timeline anchor
  - Interactive mode: Shows top N results for manual anchor selection
  - Combines semantic search discovery with timeline context retrieval
- **User Prompt Semantic Search**: Raw user prompts now indexed in Chroma for semantic discovery
- **Enhanced MCP Tools**: All 8 existing search tools now support hybrid search
  - search_observations - Now uses semantic + temporal hybrid algorithm
  - search_sessions - Semantic search across session summaries
  - search_user_prompts - Semantic search across raw prompts
  - find_by_concept, find_by_file, find_by_type - Enhanced with semantic capabilities
  - get_recent_context - Unchanged (temporal only)
  - get_context_timeline - Unchanged (anchor-based temporal)

### Changed
- **Search Server**: Expanded from ~500 to ~1,500 lines with hybrid search implementation
- **Worker Service**: Now initializes ChromaSync and handles Chroma MCP lifecycle
- **Search Pipeline**: Now follows semantic-first strategy with temporal ordering
  ```
  Query → Chroma Semantic Search (top 100) → 90-day Filter → SQLite Hydration (temporal order) → Results
  ```
- **Worker Resilience**: Worker no longer crashes when Chroma MCP unavailable; gracefully falls back to FTS5

### Fixed
- **Critical temporal filtering bug**: Fixed deduplication and date range filtering in search results
- **User prompt formatting bug**: Corrected field reference in search result formatting
- **Worker crash prevention**: Worker now handles missing Chroma MCP gracefully instead of crashing

### Technical Details
- New files:
  - src/services/sync/ChromaSync.ts (738 lines) - Vector database sync service
  - experiment/chroma-search-test.ts - Comprehensive hybrid search testing

## [4.3.4] - 2025-11-02

**Breaking Changes**: None (patch version)

**Fixes**:
- Fixed SessionStart hooks running on session resume (plugin/hooks/hooks.json:4)
- Added matcher configuration to only run SessionStart hooks on startup, clear, or compact events
- Prevents unnecessary hook execution and improves performance on session resume

**Technical Details**:
- Modified: plugin/hooks/hooks.json:4 (added `"matcher": "startup|clear|compact"`)
- Impact: Hooks now skip execution when resuming existing sessions

## [4.3.3] - 2025-10-27

**Breaking Changes**: None (patch version)

**Improvements**:
- Made session display count configurable via constant (DISPLAY_SESSION_COUNT = 8) in src/hooks/context-hook.ts:11
- Added first-time setup detection with helpful user messaging in src/hooks/user-message-hook.ts:12-39
- Improved user experience: First install message clarifies why it appears under "Plugin Hook Error"

**Fixes**:
- Cleaned up profanity in code comments (src/hooks/context-hook.ts:3)
- Fixed first-time setup UX by detecting missing node_modules and showing informative message

**Technical Details**:
- Modified: src/hooks/context-hook.ts:11 (configurable DISPLAY_SESSION_COUNT constant)
- Modified: src/hooks/user-message-hook.ts:12-39 (first-time setup detection and messaging)
- Modified: plugin/scripts/context-hook.js (rebuilt)
- Modified: plugin/scripts/user-message-hook.js (rebuilt)

## [4.3.2] - 2025-10-27

**Breaking Changes**: None (patch version)

**Improvements**:
- Added user-message-hook for displaying context to users via stderr mechanism
- Enhanced context visibility: Hook fires simultaneously with context injection, sending duplicate message as "error" so Claude Code displays it to users
- Added comprehensive documentation (4 new MDX files covering architecture evolution, context engineering, hooks architecture, and progressive disclosure)
- Improved cross-platform path handling in context-hook

**Technical Details**:
- New files:
  - src/hooks/user-message-hook.ts (stderr-based user-facing context display)
  - plugin/scripts/user-message-hook.js (built hook executable)
  - docs/architecture-evolution.mdx (801 lines)
  - docs/context-engineering.mdx (222 lines)
  - docs/hooks-architecture.mdx (784 lines)
  - docs/progressive-disclosure.mdx (655 lines)
- Modified:
  - plugin/hooks/hooks.json (added user-message-hook configuration)
  - src/hooks/context-hook.ts (improved path handling)
  - scripts/build-hooks.js (build support for new hook)
- Design rationale: Error messages don't get added to context, so we intentionally duplicate context output via stderr for user visibility. This is a temporary workaround until Claude Code potentially adds ability to share messages with both user and context simultaneously.

## [4.3.1] - 2025-10-26

## Fixes

- **Fixed SessionStart hook context injection** by silencing npm install output (`plugin/hooks/hooks.json:25`)
- Changed npm loglevel from `--loglevel=error` to `--loglevel=silent` to ensure clean JSON output
- **Consolidated hooks architecture** by removing bin/hooks wrapper layer (`src/hooks/*-hook.ts`)
- Fixed double shebang issues in hook executables (esbuild now adds shebang during build)

## Technical Details

- **Modified**: `plugin/hooks/hooks.json` (npm install verbosity)
- **Removed**: `src/bin/hooks/*` (wrapper layer no longer needed)
- **Consolidated**: Hook logic moved directly into `src/hooks/*-hook.ts` files
- **Root cause**: npm install stderr/stdout was polluting hook JSON output, preventing context injection

## Breaking Changes

None (patch version)
