* feat: implement folder index generator (Phase 1)

Add automatic CLAUDE.md generation for folders containing observed files.
This enables IDE context providers to access relevant memory observations.

Core modules:
- FolderDiscovery: Extract folders from observation file paths
- FolderTimelineCompiler: Compile chronological timeline per folder
- ClaudeMdGenerator: Write CLAUDE.md with tag-based content replacement
- FolderIndexOrchestrator: Coordinate regeneration on observation save

Integration:
- Event-driven regeneration after observation save in ResponseProcessor
- HTTP endpoints for folder discovery, timeline, and manual generation
- Settings for enabling/configuring folder index behavior

The <claude-mem-context> tag wrapping ensures:
- Manual CLAUDE.md content is preserved
- Auto-generated content won't be recursively observed
- Clean separation between user and system content

* feat: add updateFolderClaudeMd function to CursorHooksInstaller

Adds function to update CLAUDE.md files for folders touched by observations.
Uses existing /api/search/by-file endpoint, preserves content outside
<claude-mem-context> tags, and writes atomically via temp file + rename.

- src/services/folder-index/ directory (5 files)
- FolderIndexRoutes.ts
- folder-index settings from SettingsDefaultsManager
- folder-index route registration from worker-service

* feat: add worktree-aware project filtering for unified timelines

Detect git worktrees and show both parent repo and worktree observations
in the session start timeline. When running in a worktree, the context
now includes observations from both projects, interleaved chronologically.

- Add detectWorktree() utility to identify worktree directories
- Add getProjectContext() to return parent + worktree projects
- Update context hook to pass multi-project queries
- Add queryObservationsMulti() and querySummariesMulti() for IN clauses
- Maintain backward compatibility with single-project queries

* fix: restructure logging to prove session correctness and reduce noise

Add critical logging at each stage of the session lifecycle to prove the session ID chain (contentSessionId → sessionDbId → memorySessionId) stays aligned. New logs include CREATED, ENQUEUED, CLAIMED, MEMORY_ID_CAPTURED, STORING, and STORED. Move intermediate migration and backfill progress logs to DEBUG level to reduce noise, keeping only essential initialization and completion logs at INFO level.

* refactor: extract folder CLAUDE.md utils to shared location

Moves folder CLAUDE.md utilities from CursorHooksInstaller to a new
shared utils file. Removes Cursor registry dependency - file paths
from observations are already absolute, no workspace lookup needed.

New file: src/utils/claude-md-utils.ts
- replaceTaggedContent() - preserves user content outside tags
- writeClaudeMdToFolder() - atomic writes with tag preservation
- formatTimelineForClaudeMd() - API response to compact markdown
- updateFolderClaudeMdFiles() - orchestrates folder updates

* fix: trigger folder CLAUDE.md updates when observations are saved

The folder CLAUDE.md update was previously only triggered in
syncAndBroadcastSummary, but summaries run with observationCount=0
(observations are saved separately). Moved the update logic to
syncAndBroadcastObservations where file paths are available.

* docs: add project-specific CLAUDE.md with architecture and development notes

* fix: exclude project root from auto-generated CLAUDE.md updates

Skip folders containing .git directory when auto-updating subfolder
CLAUDE.md files. This ensures:

1. Root CLAUDE.md remains user-managed and untouched by the system
2. SessionStart context injection stays pristine throughout the session
3. Subfolder CLAUDE.md files continue to receive live context updates
4. Cleaner separation between user-authored root docs and auto-generated folder indexes

* fix: prevent crash from resuming stale SDK sessions on worker restart

When the worker restarts, it was incorrectly passing the `resume` parameter
to INIT prompts (lastPromptNumber=1) when a memorySessionId existed from a
previous SDK session. This caused "Claude Code process exited with code 1"
crashes because the SDK tried to resume into a session that no longer exists.

Root cause: The resume condition only checked `hasRealMemorySessionId` but
did not verify that this was a CONTINUATION prompt (lastPromptNumber > 1).

Fix: Add `session.lastPromptNumber > 1` check to the resume condition:
- Before: `...(hasRealMemorySessionId && { resume: session.memorySessionId })`
- After: `...(hasRealMemorySessionId && session.lastPromptNumber > 1 && { resume: ... })`

Also added:
- Enhanced debug logging that warns when skipping resume for INIT prompts
- Unit tests in tests/sdk-agent-resume.test.ts (9 test cases)

* fix: properly handle Chroma MCP connection errors

Previously, ensureCollection() caught ALL errors from chroma_get_collection_info
and assumed they meant "collection doesn't exist", triggering unnecessary
collection creation attempts. Connection errors like "Not connected" or
"MCP error -32000: Connection closed" would cascade into failed creation attempts.

Similarly, queryChroma() would silently return empty results when the MCP call
failed, masking the underlying connection problem.

Changes:
- ensureCollection(): Detect connection errors and re-throw immediately instead
  of attempting collection creation
- queryChroma(): Wrap MCP call in try-catch and throw connection errors instead
  of returning empty results
- Both methods reset connection state (connected=false, client=null) on
  connection errors so subsequent operations can attempt to reconnect

* pushed

* fix: scope regenerate-claude-md.ts to current working directory

Critical bug fix: The script was querying ALL observations from the database
across ALL projects ever recorded (1396+ folders), then attempting to write
CLAUDE.md files everywhere including other projects, non-existent paths, and
ignored directories.

Changes:
- Use git ls-files to discover folders (respects .gitignore automatically)
- Filter database query to current project only (by folder name)
- Use relative paths for database queries (matches storage format)
- Add --clean flag to remove auto-generated CLAUDE.md files
- Add fallback directory walker for non-git repos

Now correctly scopes to 26 folders with observations instead of 1396+.

* fix: cleanup mode strips tags instead of deleting files blindly

The cleanup mode was incorrectly deleting entire files that contained
<claude-mem-context> tags. The correct behavior (per original design):

1. Strip the <claude-mem-context>...</claude-mem-context> section
2. If empty after stripping → delete the file
3. If has remaining content → save the stripped version

Now properly preserves user content in CLAUDE.md files while removing
only the auto-generated sections.

* CLAUDE.md updates

* fix: resolve CLAUDE.md files to correct directory in worktree setups

When using git worktrees, CLAUDE.md files were being written relative to
the worker's process.cwd() instead of the actual project directory. This
fix threads the project's cwd from message processing through to the file
writing utilities, ensuring CLAUDE.md files are created in the correct
project directory regardless of where the worker was started.

Changes:
- Add projectRoot parameter to updateFolderClaudeMdFiles for path resolution
- Thread projectRoot through ResponseProcessor call chain
- Track lastCwd from messages in SDKAgent, GeminiAgent, OpenRouterAgent
- Add tests for relative/absolute path handling with projectRoot

* fix: graceful exit strategy to prevent Windows Terminal tab accumulation (#625)

Problem:
Windows Terminal keeps tabs open when processes exit with code 1, leading
to tab accumulation during worker lifecycle operations (start, stop, restart,
version mismatches, port conflicts). This created a poor user experience with
dozens of orphaned terminal tabs.

Solution:
Implemented graceful exit strategy using exit code 0 for all expected failure
scenarios. The wrapper and plugin handle restart logic, so child processes
don't need to signal failure with non-zero exit codes.

Key Changes:
- worker-service.ts: Changed all process.exit(1) to process.exit(0) in:
  - Port conflict scenarios
  - Version mismatch recovery
  - Daemon spawn failures
  - Health check timeouts
  - Restart failures
  - Worker startup errors
- mcp-server.ts: Changed fatal error exit from 1 to 0
- ProcessManager.ts: Changed signal handler error exit from 1 to 0
- hook-command.ts: Changed hook error exit code from 1 to 2 (BLOCKING_ERROR)
  to ensure users see error messages (per Claude Code docs, exit 1 only shows
  in verbose mode)

All exits include explanatory comments documenting the graceful exit strategy.

Persistent memory compression system built for Claude Code.

Quick Start • How It Works • Search Tools • Documentation • Configuration • Troubleshooting • License

Claude-Mem seamlessly preserves context across sessions by automatically capturing tool usage observations, generating semantic summaries, and making them available to future sessions. This enables Claude to maintain continuity of knowledge about projects even after sessions end or reconnect.

Quick Start

Start a new Claude Code session in the terminal and enter the following commands:

> /plugin marketplace add thedotmack/claude-mem

> /plugin install claude-mem

Restart Claude Code. Context from previous sessions will automatically appear in new sessions.

Key Features:

🧠 Persistent Memory - Context survives across sessions
📊 Progressive Disclosure - Layered memory retrieval with token cost visibility
🔍 Skill-Based Search - Query your project history with mem-search skill
🖥️ Web Viewer UI - Real-time memory stream at http://localhost:37777
💻 Claude Desktop Skill - Search memory from Claude Desktop conversations
🔒 Privacy Control - Use <private> tags to exclude sensitive content from storage
⚙️ Context Configuration - Fine-grained control over what context gets injected
🤖 Automatic Operation - No manual intervention required
🔗 Citations - Reference past observations with IDs (access via http://localhost:37777/api/observation/{id} or view all in the web viewer at http://localhost:37777)
🧪 Beta Channel - Try experimental features like Endless Mode via version switching

How It Works

Core Components:

5 Lifecycle Hooks - SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd (6 hook scripts)
Smart Install - Cached dependency checker (pre-hook script, not a lifecycle hook)
Worker Service - HTTP API on port 37777 with web viewer UI and 10 search endpoints, managed by Bun
SQLite Database - Stores sessions, observations, summaries
mem-search Skill - Natural language queries with progressive disclosure
Chroma Vector Database - Hybrid semantic + keyword search for intelligent context retrieval

See Architecture Overview for details.

MCP Search Tools

Claude-Mem provides intelligent memory search through 4 MCP tools following a token-efficient 3-layer workflow pattern:

The 3-Layer Workflow:

search - Get compact index with IDs (~50-100 tokens/result)
timeline - Get chronological context around interesting results
get_observations - Fetch full details ONLY for filtered IDs (~500-1,000 tokens/result)

How It Works:

Claude uses MCP tools to search your memory
Start with search to get an index of results
Use timeline to see what was happening around specific observations
Use get_observations to fetch full details for relevant IDs
~10x token savings by filtering before fetching details

Available MCP Tools:

search - Search memory index with full-text queries, filters by type/date/project
timeline - Get chronological context around a specific observation or query
get_observations - Fetch full observation details by IDs (always batch multiple IDs)
__IMPORTANT - Workflow documentation (always visible to Claude)
