+# Comprehensive Claude-Mem Installer with @clack/prompts
+
+## Overview
+
+Build a beautiful, animated CLI installer for claude-mem using `@clack/prompts` (v1.0.1). Distributable via `npx claude-mem-installer` and `curl -fsSL https://install.cmem.ai | bash`. Replaces the need for users to manually clone, build, configure settings, and start the worker.
+
+**Worktree**: `feat/animated-installer` at `.claude/worktrees/animated-installer`
+
+---
+
+## Phase 0: Documentation & API Reference
+
+### Allowed APIs (@clack/prompts v1.0.1, ESM-only)
+
+| API | Signature | Use Case |
+|-----|-----------|----------|
+| `intro(title?)` | `void` | Opening banner |
+| `outro(message?)` | `void` | Completion message |
+| `cancel(message?)` | `void` | User cancelled |
+| `isCancel(value)` | `boolean` | Check if user pressed Ctrl+C |
+| `text(opts)` | `Promise<string \| symbol>` | API key input, port, data dir |
+| `password(opts)` | `Promise<string \| symbol>` | API key input (masked) |
+| `select(opts)` | `Promise<Value \| symbol>` | Provider, model, auth method |
+| `multiselect(opts)` | `Promise<Value[] \| symbol>` | IDE selection, observation types |
+| `confirm(opts)` | `Promise<boolean \| symbol>` | Enable Chroma, start worker |
+| `spinner()` | `SpinnerResult` | Installing deps, building, starting worker |
+| `progress(opts)` | `ProgressResult` | Multi-step installation progress |
+| `tasks(tasks[])` | `Promise<void>` | Sequential install steps |
+| `group(prompts, opts)` | `Promise<Results>` | Chain prompts with shared results |
+| `note(message, title)` | `void` | Display settings summary, next steps |
+| `log.info/success/warn/error(msg)` | `void` | Status messages |
+| `box(message, title, opts)` | `void` | Welcome box, completion summary |
+
+### Anti-Patterns
+- Do NOT use `require()` — package is ESM-only
+- Do NOT call prompts without TTY check first — hangs indefinitely in non-TTY
+- Do NOT forget `isCancel()` check after every prompt (or use `group()` with `onCancel`)
+- Do NOT use `chalk` — use `picocolors` (clack's dep) for consistency
+- `text()` has no numeric mode — validate manually for port numbers
+- `spinner.stop()` does not accept status codes — use `spinner.error()` for failures
+
+### Distribution Patterns
+- **npx**: `package.json` `bin` field → `"./dist/index.js"`, file needs `#!/usr/bin/env node`
+- **curl|bash**: Shell bootstrap downloads JS, runs `node script.js` directly (preserves TTY)
+- **esbuild**: Bundle to single ESM file, `platform: 'node'`, `banner` for shebang
+
+### Key Source Files to Reference
+- Settings defaults: `src/shared/SettingsDefaultsManager.ts` (lines 73-125)
+- Settings validation: `src/services/server/SettingsRoutes.ts`
+- Worker startup: `src/services/worker-service.ts` (lines 337-359)
+- Health check: `src/services/infrastructure/HealthMonitor.ts`
+- Plugin registration: `plugin/.claude-plugin/plugin.json`, `.claude-plugin/marketplace.json`
+- Marketplace sync: `scripts/sync-marketplace.cjs`
+- Cursor integration: `src/services/integrations/CursorHooksInstaller.ts`
+- Existing OpenClaw installer: `install/public/openclaw.sh` (reference for logic, not code to copy)
+
+---
+
+## Phase 1: Project Scaffolding
+
+**Goal**: Set up the installer package structure with build tooling.
+
+### Tasks
+
+1. **Create directory structure** in the worktree:
+   ```
+   installer/
+   ├── src/
+   │   ├── index.ts              # Entry point with TTY guard
+   │   ├── steps/
+   │   │   ├── welcome.ts        # intro + version check
+   │   │   ├── dependencies.ts   # bun, uv, git checks
+   │   │   ├── ide-selection.ts  # IDE picker + registration
+   │   │   ├── provider.ts       # AI provider + API key
+   │   │   ├── settings.ts       # Additional settings config
+   │   │   ├── install.ts        # Clone, build, register plugin
+   │   │   ├── worker.ts         # Start worker + health check
+   │   │   └── complete.ts       # Summary + next steps
+   │   └── utils/
+   │       ├── system.ts         # OS detection, command runner
+   │       ├── dependencies.ts   # bun/uv/git install helpers
+   │       └── settings-writer.ts # Write ~/.claude-mem/settings.json
+   ├── build.mjs                 # esbuild config
+   ├── package.json              # bin, type: module, deps
+   └── tsconfig.json
+   ```
+
+2. **Create `package.json`**:
+   ```json
+   {
+     "name": "claude-mem-installer",
+     "version": "1.0.0",
+     "type": "module",
+     "bin": { "claude-mem-installer": "./dist/index.js" },
+     "files": ["dist"],
+     "scripts": {
+       "build": "node build.mjs",
+       "dev": "node build.mjs && node dist/index.js"
+     },
+     "dependencies": {
+       "@clack/prompts": "^1.0.1",
+       "picocolors": "^1.1.1"
+     },
+     "devDependencies": {
+       "esbuild": "^0.24.0",
+       "typescript": "^5.7.0",
+       "@types/node": "^22.0.0"
+     },
+     "engines": { "node": ">=18.0.0" }
+   }
+   ```
+
+3. **Create `build.mjs`**:
+   - esbuild bundle: `entryPoints: ['src/index.ts']`, `format: 'esm'`, `platform: 'node'`, `target: 'node18'`
+   - Banner: `#!/usr/bin/env node`
+   - Output: `dist/index.js`
+
+4. **Create `tsconfig.json`**:
+   - `module: "ESNext"`, `target: "ES2022"`, `moduleResolution: "bundler"`
+
+5. **Run `npm install`** in installer/ directory
+
+### Verification
+- [ ] `node build.mjs` succeeds
+- [ ] `dist/index.js` exists with shebang
+- [ ] `node dist/index.js` runs (even if empty installer)
+
+---
+
+## Phase 2: Entry Point + Welcome Screen
+
+**Goal**: Create the main entry point with TTY detection and a beautiful welcome screen.
+
+### Tasks
+
+1. **`src/index.ts`** — Entry point:
+   - TTY guard: if `!process.stdin.isTTY`, print error directing user to `npx claude-mem-installer`, exit 1
+   - Import and call `runInstaller()` from steps
+   - Top-level catch → `p.cancel()` + exit 1
+
+2. **`src/steps/welcome.ts`** — Welcome step:
+   - `p.intro()` with styled title using picocolors: `" claude-mem installer "`
+   - Display version info via `p.log.info()`
+   - Check if already installed (detect `~/.claude-mem/settings.json` and `~/.claude/plugins/marketplaces/thedotmack/`)
+   - If upgrade detected, `p.confirm()`: "claude-mem is already installed. Upgrade?"
+   - `p.select()` for install mode: Fresh Install vs Upgrade vs Configure Only
+
+3. **`src/utils/system.ts`** — System utilities:
+   - `detectOS()`: returns 'macos' | 'linux' | 'windows'
+   - `commandExists(cmd)`: checks if command is in PATH
+   - `runCommand(cmd, args)`: executes shell command, returns { stdout, stderr, exitCode }
+   - `expandHome(path)`: resolves `~` to home directory
+
+### Verification
+- [ ] Running `node dist/index.js` shows intro banner
+- [ ] Ctrl+C triggers cancel message
+- [ ] Non-TTY (piped) shows error and exits
+
+---
+
+## Phase 3: Dependency Checks
+
+**Goal**: Check and install required dependencies (Bun, uv, git, Node.js version).
+
+### Tasks
+
+1. **`src/steps/dependencies.ts`** — Dependency checker:
+   - Use `p.tasks()` to check each dependency sequentially with animated spinners:
+     - **Node.js**: Verify >= 18.0.0 via `process.version`
+     - **git**: `commandExists('git')`, show install instructions per OS if missing
+     - **Bun**: Check PATH + common locations (`~/.bun/bin/bun`, `/usr/local/bin/bun`, `/opt/homebrew/bin/bun`). Min version 1.1.14. Offer to auto-install from `https://bun.sh/install`
+     - **uv**: Check PATH + common locations (`~/.local/bin/uv`, `~/.cargo/bin/uv`). Offer to auto-install from `https://astral.sh/uv/install.sh`
+   - For missing deps: `p.confirm()` to auto-install, or show manual instructions
+   - After install attempts, re-verify each dep
+
+2. **`src/utils/dependencies.ts`** — Install helpers:
+   - `installBun()`: downloads and runs bun install script
+   - `installUv()`: downloads and runs uv install script
+   - `findBinary(name, extraPaths[])`: searches PATH + known locations
+   - `checkVersion(binary, minVersion)`: parses `--version` output
+
+### Verification
+- [ ] Shows green checkmarks for found dependencies
+- [ ] Shows yellow warnings for missing deps with install option
+- [ ] Auto-install actually installs bun/uv when confirmed
+- [ ] Fails gracefully if git is missing (can't auto-install)
+
+---
+
+## Phase 4: IDE Selection & Provider Configuration
+
+**Goal**: Let user choose IDEs and configure AI provider with API keys.
+
+### Tasks
+
+1. **`src/steps/ide-selection.ts`** — IDE picker:
+   - `p.multiselect()` with options:
+     - Claude Code (default selected, hint: "recommended")
+     - Cursor
+     - Windsurf (hint: "coming soon", disabled: true)
+   - For Claude Code: explain plugin will be registered via marketplace
+   - For Cursor: explain hooks will be installed via CursorHooksInstaller pattern
+   - Store selections for later installation steps
+
+2. **`src/steps/provider.ts`** — AI provider configuration:
+   - `p.select()` for provider:
+     - **Claude** (hint: "recommended — uses your Claude subscription")
+     - **Gemini** (hint: "free tier available")
+     - **OpenRouter** (hint: "free models available")
+   - **If Claude selected**:
+     - `p.select()` for auth method: "CLI (Max Plan subscription)" vs "API Key"
+     - If API key: `p.password()` for key input
+   - **If Gemini selected**:
+     - `p.password()` for API key (required)
+     - `p.select()` for model: gemini-2.5-flash-lite (default), gemini-2.5-flash, gemini-3-flash-preview
+     - `p.confirm()` for rate limiting (default: true)
+   - **If OpenRouter selected**:
+     - `p.password()` for API key (required)
+     - `p.text()` for model (default: `xiaomi/mimo-v2-flash:free`)
+   - Validate API keys where possible (non-empty, format check)
+
+### Verification
+- [ ] Multiselect allows picking multiple IDEs
+- [ ] Provider selection shows correct follow-up prompts
+- [ ] API keys are masked during input
+- [ ] Cancel at any step triggers graceful exit
+
+---
+
+## Phase 5: Settings Configuration
+
+**Goal**: Configure additional settings with sensible defaults.
+
+### Tasks
+
+1. **`src/steps/settings.ts`** — Settings wizard:
+   - `p.confirm()`: "Use default settings?" (recommended) — if yes, skip detailed config
+   - If customizing, use `p.group()` for:
+     - **Worker port**: `p.text()` with default 37777, validate 1024-65535
+     - **Data directory**: `p.text()` with default `~/.claude-mem`
+     - **Context observations**: `p.text()` with default 50, validate 1-200
+     - **Log level**: `p.select()` — DEBUG, INFO (default), WARN, ERROR
+     - **Python version**: `p.text()` with default 3.13
+     - **Chroma vector search**: `p.confirm()` (default: true)
+       - If yes, `p.select()` mode: local (default) vs remote
+       - If remote: `p.text()` for host, port, `p.confirm()` for SSL
+   - Show settings summary via `p.note()` before proceeding
+
+2. **`src/utils/settings-writer.ts`** — Write settings:
+   - Build flat key-value settings object matching SettingsDefaultsManager schema
+   - Merge with existing settings if upgrading (preserve user customizations)
+   - Write to `~/.claude-mem/settings.json`
+   - Create `~/.claude-mem/` directory if it doesn't exist
+
+### Verification
+- [ ] Default settings mode skips all detailed prompts
+- [ ] Custom settings validates all inputs
+- [ ] Settings file written matches SettingsDefaultsManager schema exactly
+- [ ] Existing settings preserved on upgrade
+
+---
+
+## Phase 6: Installation Execution
+
+**Goal**: Clone repo, build plugin, register with IDEs, start worker.
+
+### Tasks
+
+1. **`src/steps/install.ts`** — Installation runner:
+   - Use `p.tasks()` for visual progress:
+     - **"Cloning claude-mem repository"**: `git clone --depth 1 https://github.com/thedotmack/claude-mem.git` to temp dir
+     - **"Installing dependencies"**: `npm install` in cloned repo
+     - **"Building plugin"**: `npm run build` in cloned repo
+     - **"Registering plugin"**: Copy plugin files to `~/.claude/plugins/marketplaces/thedotmack/`
+       - Create marketplace.json, plugin.json structure
+       - Register in `~/.claude/plugins/known_marketplaces.json`
+       - Add to `~/.claude/plugins/installed_plugins.json`
+       - Enable in `~/.claude/settings.json` under `enabledPlugins`
+     - **"Installing dependencies"** (in marketplace dir): `npm install`
+   - For Cursor (if selected):
+     - **"Configuring Cursor hooks"**: Run Cursor hooks installer logic
+     - Write hooks.json to `~/.cursor/` or project-level `.cursor/`
+     - Configure MCP in `.cursor/mcp.json`
+
+2. **`src/steps/worker.ts`** — Worker startup:
+   - Use `p.spinner()` for worker startup:
+     - Start worker: `bun plugin/scripts/worker-service.cjs` (from marketplace dir)
+     - Write PID file to `~/.claude-mem/worker.pid`
+   - Two-stage health check (copy pattern from OpenClaw installer):
+     - Stage 1: Poll `/api/health` — spinner message: "Starting worker service..."
+     - Stage 2: Poll `/api/readiness` — spinner message: "Initializing database..."
+     - Budget: 30 attempts, 1 second apart
+     - On success: `spinner.stop("Worker running on port {port}")`
+     - On failure: `spinner.error("Worker failed to start")`, show log path
+
+### Verification
+- [ ] Plugin files exist at `~/.claude/plugins/marketplaces/thedotmack/`
+- [ ] known_marketplaces.json updated
+- [ ] installed_plugins.json updated
+- [ ] settings.json has enabledPlugins entry
+- [ ] Worker responds to `/api/health` with 200
+- [ ] Worker responds to `/api/readiness` with 200
+
+---
+
+## Phase 7: Completion & Summary
+
+**Goal**: Show success screen with configuration summary and next steps.
+
+### Tasks
+
+1. **`src/steps/complete.ts`** — Completion screen:
+   - `p.note()` with configuration summary:
+     - Provider + model
+     - IDEs configured
+     - Data directory
+     - Worker port
+     - Chroma enabled/disabled
+   - `p.note()` with next steps:
+     - "Open Claude Code and start a conversation — memory is automatic!"
+     - "View your memories: http://localhost:{port}"
+     - "Search past work: use /mem-search in Claude Code"
+     - If Cursor: "Open Cursor — hooks are active in your projects"
+   - `p.outro()` with styled completion message
+
+### Verification
+- [ ] Summary accurately reflects chosen settings
+- [ ] URLs use correct port from settings
+- [ ] Next steps are relevant to selected IDEs
+
+---
+
+## Phase 8: curl|bash Bootstrap Script
+
+**Goal**: Create the shell bootstrap script for `curl -fsSL https://install.cmem.ai | bash`.
+
+### Tasks
+
+1. **`install/public/install.sh`** — Bootstrap script:
+   - Check for Node.js >= 18 (required to run the installer)
+   - Download bundled installer JS to temp file
+   - Execute with `node` directly (preserves TTY for @clack/prompts)
+   - Cleanup temp file on exit (trap)
+   - Support `--non-interactive` flag passthrough
+   - Support `--provider=X --api-key=Y` flag passthrough
+
+2. **Update `install/vercel.json`** to serve `install.sh` alongside `openclaw.sh`
+
+### Verification
+- [ ] `curl -fsSL https://install.cmem.ai | bash` downloads and runs installer
+- [ ] Interactive prompts work after curl download
+- [ ] Temp file cleaned up on success and failure
+- [ ] Flags pass through correctly
+
+---
+
+## Phase 9: Final Verification
+
+### Checks
+- [ ] `npm run build` in installer/ produces single-file `dist/index.js`
+- [ ] `node dist/index.js` runs full wizard flow
+- [ ] Fresh install on clean system works end-to-end
+- [ ] Upgrade path preserves existing settings
+- [ ] Ctrl+C at any step exits cleanly
+- [ ] Non-TTY shows error message
+- [ ] All settings written match SettingsDefaultsManager.ts defaults schema
+- [ ] Worker health check succeeds after install
+- [ ] Plugin appears in Claude Code plugin list
+- [ ] grep for deprecated/non-existent APIs returns 0 results
+- [ ] No `require()` calls in source (ESM-only)
+- [ ] No `chalk` imports (use picocolors)

+## [v10.3.1] - 2026-02-19
+
+## Fix: Prevent Duplicate Worker Daemons and Zombie Processes
+
+Three root causes of chroma-mcp timeouts identified and fixed:
+
+### PID-based daemon guard
+Exit immediately on startup if PID file points to a live process. Prevents the race condition where hooks firing simultaneously could start multiple daemons before either wrote a PID file.
+
+### Port-based daemon guard
+Exit if port 37777 is already bound — runs before WorkerService constructor registers keepalive signal handlers that previously prevented exit on EADDRINUSE.
+
+### Guaranteed process.exit() after HTTP shutdown
+HTTP shutdown (POST /api/admin/shutdown) now calls `process.exit(0)` in a `try/finally` block. Previously, zombie workers stayed alive after shutdown, and background tasks reconnected to chroma-mcp, spawning duplicate subprocesses contending for the same data directory.
+
+## [v10.3.0] - 2026-02-18
+
+## Replace WASM Embeddings with Persistent chroma-mcp MCP Connection
+
+### Highlights
+
+- **New: ChromaMcpManager** — Singleton stdio MCP client communicating with chroma-mcp via `uvx`, replacing the previous ChromaServerManager (`npx chroma run` + `chromadb` npm + ONNX/WASM)
+- **Eliminates native binary issues** — No more segfaults, WASM embedding failures, or cross-platform install headaches
+- **Graceful subprocess lifecycle** — Wired into GracefulShutdown for clean teardown; zombie process prevention with kill-on-failure and stale `onclose` handler guards
+- **Connection backoff** — 10-second reconnect backoff prevents chroma-mcp spawn storms
+- **SQL injection guards** — Added parameterization to ChromaSync ID exclusion queries
+- **Simplified ChromaSync** — Reduced complexity by delegating embedding concerns to chroma-mcp
+
+### Breaking Changes
+
+None — backward compatible. ChromaDB data is preserved; only the connection mechanism changed.
+
+### Files Changed
+
+- `src/services/sync/ChromaMcpManager.ts` (new) — MCP client singleton
+- `src/services/sync/ChromaServerManager.ts` (deleted) — Old WASM/native approach
+- `src/services/sync/ChromaSync.ts` — Simplified to use MCP client
+- `src/services/worker-service.ts` — Updated startup sequence
+- `src/services/infrastructure/GracefulShutdown.ts` — Subprocess cleanup integration
+
+## [v10.2.6] - 2026-02-18
+
+## Bug Fixes
+
+### Zombie Process Prevention (#1168, #1175)
+
+Observer Claude CLI subprocesses were accumulating as zombies — processes that never exited after their session ended, causing massive resource leaks on long-running systems.
+
+**Root cause:** When observer sessions ended (via idle timeout, abort, or error), the spawned Claude CLI subprocesses were not being reliably killed. The existing `ensureProcessExit()` in `SDKAgent` only covered the happy path; sessions terminated through `SessionRoutes` or `worker-service` bypassed process cleanup entirely.
+
+**Fix — dual-layer approach:**
+
+1. **Immediate cleanup:** Added `ensureProcessExit()` calls to the `finally` blocks in both `SessionRoutes.ts` and `worker-service.ts`, ensuring every session exit path kills its subprocess
+2. **Periodic reaping:** Added `reapStaleSessions()` to `SessionManager` — a background interval that scans `~/.claude-mem/observer-sessions/` for stale PID files, verifies the process is still running, and kills any orphans with SIGKILL escalation
+
+This ensures no observer subprocess survives beyond its session lifetime, even in crash scenarios.
+
+## [v10.2.5] - 2026-02-18
+
+### Bug Fixes
+
+- **Self-healing message queue**: Renamed `claimAndDelete` → `claimNextMessage` with atomic self-healing — automatically resets stale processing messages (>60s) back to pending before claiming, eliminating stuck messages from generator crashes without external timers
+- **Removed redundant idle-timeout reset**: The `resetStaleProcessingMessages()` call during idle timeout in worker-service was removed (startup reset kept), since the atomic self-healing in `claimNextMessage` now handles recovery inline
+- **TypeScript diagnostic fix**: Added `QUEUE` to logger `Component` type
+
+### Tests

+
+## Chroma Vector DB Backfill Fix
+
+Fixes the Chroma backfill system to correctly sync all SQLite observations into the vector database on worker startup.
+
+### Bug Fixes
+
+- **Backfill all projects on startup** — `backfillAllProjects()` now runs on worker startup, iterating all projects in SQLite and syncing missing observations to Chroma. Previously `ensureBackfilled()` existed but was never called, leaving Chroma with incomplete data after cache clears.
+
+- **Fixed critical collection routing bug** — Backfill now uses the shared `cm__claude-mem` collection (matching how DatabaseManager and SearchManager operate) instead of creating per-project orphan collections that no search path reads from.
+
+- **Hardened collection name sanitization** — Project names with special characters (e.g., "YC Stuff") are sanitized for Chroma's naming constraints, including stripping trailing non-alphanumeric characters.
+
+- **Eliminated shared mutable state** — `ensureBackfilled()` and `getExistingChromaIds()` now accept project as a parameter instead of mutating instance state, keeping a single Chroma connection while avoiding fragile property mutation across iterations.
+
+- **Chroma readiness guard** — Backfill waits for Chroma server readiness before running, preventing spurious error logs when Chroma fails to start.
+
+### Changed Files
+
+- `src/services/sync/ChromaSync.ts` — Core backfill logic, sanitization, parameter passing
+- `src/services/worker-service.ts` — Startup backfill trigger + readiness guard
+- `src/utils/logger.ts` — Added `CHROMA_SYNC` log component
+
+## [v10.2.3] - 2026-02-17
+
+## Fix Chroma ONNX Model Cache Corruption
+
+Addresses the persistent embedding pipeline failures reported across #1104, #1105, #1110, and subsequent sessions. Three root causes identified and fixed:
+
+### Changes
+
+- **Removed nuclear `bun pm cache rm`** from both `smart-install.js` and `sync-marketplace.cjs`. This was added in v10.2.2 for the now-removed sharp dependency but destroyed all cached packages, breaking the ONNX resolution chain.
+- **Added `bun install` in plugin cache directory** after marketplace sync. The cache directory had a `package.json` with `@chroma-core/default-embed` as a dependency but never ran install, so the worker couldn't resolve it at runtime.
+- **Moved HuggingFace model cache to `~/.claude-mem/models/`** outside `node_modules`. The ~23MB ONNX model was stored inside `node_modules/@huggingface/transformers/.cache/`, so any reinstall or cache clear corrupted it.
+- **Added self-healing retry** for Protobuf parsing failures. If the downloaded model is corrupted, the cache is cleared and re-downloaded automatically on next use.
+
+### Files Changed
+
+- `scripts/smart-install.js` — removed `bun pm cache rm`
+- `scripts/sync-marketplace.cjs` — removed `bun pm cache rm`, added `bun install` in cache dir
+- `src/services/sync/ChromaSync.ts` — moved model cache, added corruption recovery
+
+## [v10.2.2] - 2026-02-17
+
+## Bug Fixes
+
+- **Removed `node-addon-api` dev dependency** — was only needed for `sharp`, which was already removed in v10.2.1
+- **Simplified native module cache clearing** in `smart-install.js` and `sync-marketplace.cjs` — replaced targeted `@img/sharp` directory deletion and lockfile removal with `bun pm cache rm`
+- Reduced ~30 lines of brittle file system manipulation to a clean Bun CLI command
+
+## [v10.2.1] - 2026-02-16
+
+## Bug Fixes
+
+- **Bun install & sharp native modules**: Fixed stale native module cache issues on Bun updates, added `node-addon-api` as a dev dependency required by sharp (#1140)
+- **PendingMessageStore consolidation**: Deduplicated PendingMessageStore initialization in worker-service; added session-scoped filtering to `resetStaleProcessingMessages` to prevent cross-session message resets (#1140)
+- **Gemini empty response handling**: Fixed silent message deletion when Gemini returns empty summary responses — now logs a warning and preserves the original message (#1138)
+- **Idle timeout session scoping**: Fixed idle timeout handler to only reset messages for the timed-out session instead of globally resetting all sessions (#1138)
+- **Shell injection in sync-marketplace**: Replaced `execSync` with `spawnSync` for rsync calls to eliminate command injection via gitignore patterns (#1138)
+- **Sharp cache invalidation**: Added cache clearing for sharp's native bindings when Bun version changes (#1138)
+- **Marketplace install**: Switched marketplace sync from npm to bun for package installation consistency (#1140)
+
+## [v10.1.0] - 2026-02-16
+
+## SessionStart System Message & Cleaner Defaults
+
+### New Features
+
+- **SessionStart `systemMessage` support** — Hooks can now display user-visible ANSI-colored messages directly in the CLI via a new `systemMessage` field on `HookResult`. The SessionStart hook uses this to render a colored timeline summary (separate from the markdown context injected for Claude), giving users an at-a-glance view of recent activity every time they start a session.
+
+- **"View Observations Live" link** — Each session start now appends a clickable `http://localhost:{port}` URL so users can jump straight to the live observation viewer.
+
+### Performance
+
+- **Truly parallel context fetching** — The SessionStart handler now uses `Promise.all` to fetch both the markdown context (for Claude) and the ANSI-colored timeline (for user display) simultaneously, eliminating the serial fetch overhead.
+
+### Defaults Changes
+
+- **Cleaner out-of-box experience** — New installs now default to a streamlined context display:
+  - Read tokens column: hidden (`CLAUDE_MEM_CONTEXT_SHOW_READ_TOKENS: false`)
+  - Work tokens column: hidden (`CLAUDE_MEM_CONTEXT_SHOW_WORK_TOKENS: false`)
+  - Savings amount: hidden (`CLAUDE_MEM_CONTEXT_SHOW_SAVINGS_AMOUNT: false`)
+  - Full observation expansion: disabled (`CLAUDE_MEM_CONTEXT_FULL_COUNT: 0`)
+  - Savings percentage remains visible by default
+
+  Existing users are unaffected — your `~/.claude-mem/settings.json` overrides these defaults.
+
+### Technical Details
+
+- Added `systemMessage?: string` to `HookResult` interface (`src/cli/types.ts`)
+- Claude Code adapter now forwards `systemMessage` in hook output (`src/cli/adapters/claude-code.ts`)
+- Context handler refactored for parallel fetch with graceful fallback (`src/cli/handlers/context.ts`)
+- Default settings tuned in `SettingsDefaultsManager` (`src/shared/SettingsDefaultsManager.ts`)
+
+## [v10.0.8] - 2026-02-16
+
+## Bug Fixes
+
+### Orphaned Subprocess Cleanup
+- Add explicit subprocess cleanup after SDK query loop using existing `ProcessRegistry` infrastructure (`getProcessBySession` + `ensureProcessExit`), preventing orphaned Claude subprocesses from accumulating
+- Closes #1010, #1089, #1090, #1068
+
+### Chroma Binary Resolution
+- Replace `npx chroma run` with absolute binary path resolution via `require.resolve`, falling back to `npx` with explicit `cwd` when the binary isn't found directly
+- Closes #1120
+
+### Cross-Platform Embedding Fix
+- Remove `@chroma-core/default-embed` which pulled in `onnxruntime` + `sharp` native binaries that fail on many platforms
+- Use WASM backend for Chroma embeddings, eliminating native binary compilation issues
+- Closes #1104, #1105, #1110

-## 🔧 Worker Lifecycle Hardening
-
-This patch release addresses critical bugs discovered during PR review of the self-spawn pattern introduced in 8.2.0. The worker daemon now handles edge cases robustly across both Unix and Windows platforms.
-
-### 🐛 Critical Bug Fixes
-
-#### Process Exit Detection Fixed
-The `waitForProcessesExit` function was crashing when processes exited during monitoring. The `process.kill(pid, 0)` call throws when a process no longer exists, which was not being caught. Now wrapped in try/catch to correctly identify exited processes.
-
-#### Spawn PID Validation
-The worker daemon now validates that `spawn()` actually returned a valid PID before writing to the PID file. Previously, spawn failures could leave invalid PID files that broke subsequent lifecycle operations.
-
-#### Cross-Platform Orphan Cleanup
-- **Unix**: Replaced single `kill` command with individual `process.kill()` calls wrapped in try/catch, so one already-exited process doesn't abort cleanup of remaining orphans
-- **Windows**: Wrapped `taskkill` calls in try/catch for the same reason
-
-#### Health Check Reliability
-Changed `waitForHealth` to use the `/api/readiness` endpoint (returns 503 until fully initialized) instead of just checking if the port is in use. Callers now wait for *actual* worker readiness, not just network availability.
-
-### 🔄 Refactoring
-
-#### Code Consolidation (-580 lines)
-Deleted obsolete process management infrastructure that was replaced by the self-spawn pattern:
-- `src/services/process/ProcessManager.ts` (433 lines) - PID management now in worker-service
-- `src/cli/worker-cli.ts` (81 lines) - CLI handling now in worker-service
-- `src/services/worker-wrapper.ts` (157 lines) - Replaced by `--daemon` flag
-
-#### Updated Hook Commands
-All hooks now use `worker-service.cjs` CLI directly instead of the deleted `worker-cli.js`.
-
-### ⏱️ Timeout Adjustments
-
-Increased timeouts throughout for compatibility with slow systems:
-
-| Component | Before | After |
-|-----------|--------|-------|
-| Default hook timeout | 120s | 300s |
-| Health check timeout | 1s | 30s |
-| Health check retries | 15 | 300 |
-| Context initialization | 30s | 300s |
-| MCP connection | 15s | 300s |
-| PowerShell commands | 5s | 60s |
-| Git commands | 30s | 300s |
-| NPM install | 120s | 600s |
-| Hook worker commands | 30s | 180s |
-
-### 🧪 Testing
-
-Added comprehensive test suites:
-- `tests/hook-constants.test.ts` - Validates timeout configurations
-- `tests/worker-spawn.test.ts` - Tests worker CLI and health endpoints
-
-### 🛡️ Additional Robustness
-
-- PID validation in restart command (matches start command behavior)
-- Try/catch around `forceKillProcess()` for graceful shutdown
-- Try/catch around `getChildProcesses()` for Windows failures
-- Improved logging for PID file operations and HTTP shutdown

-## 🚀 Gemini API as Alternative AI Provider
-
-This release introduces **Google Gemini API** as an alternative to the Claude Agent SDK for observation extraction. This gives users flexibility in choosing their AI backend while maintaining full feature parity.
-
-### ✨ New Features
-
-#### Gemini Provider Integration
-- **New `GeminiAgent`**: Complete implementation using Gemini's REST API for observation and summary extraction
-- **Provider selection**: Choose between Claude or Gemini directly in the Settings UI
-- **API key management**: Configure via UI or `GEMINI_API_KEY` environment variable
-- **Multi-turn conversations**: Full conversation history tracking for context-aware extraction
-
-#### Supported Gemini Models
-- `gemini-2.5-flash-preview-05-20` (default)
-- `gemini-2.5-pro-preview-05-06`
-- `gemini-2.0-flash`
-- `gemini-2.0-flash-lite`
-
-#### Rate Limiting
-- Built-in rate limiting for Gemini free tier (15 RPM) and paid tier (1000 RPM)
-- Configurable via `gemini_has_billing` setting in the UI
-
-#### Resilience Features
-- **Graceful fallback**: Automatically falls back to Claude SDK if Gemini is selected but no API key is configured
-- **Hot-swap providers**: Switch between Claude and Gemini without restarting the worker
-- **Empty response handling**: Messages properly marked as processed even when Gemini returns empty responses (prevents stuck queue states)
-- **Timestamp preservation**: Recovered backlog messages retain their original timestamps
-
-### 🎨 UI Improvements
-
-- **Spinning favicon**: Visual indicator during observation processing
-- **Provider status**: Clear indication of which AI provider is active
-
-### 📚 Documentation
-
-- New [Gemini Provider documentation](https://docs.claude-mem.ai/usage/gemini-provider) with setup guide and troubleshooting
-
-### ⚙️ New Settings
-
-| Setting | Values | Description |
-|---------|--------|-------------|
-| `CLAUDE_MEM_PROVIDER` | `claude` \| `gemini` | AI provider for observation extraction |
-| `CLAUDE_MEM_GEMINI_API_KEY` | string | Gemini API key |
-| `CLAUDE_MEM_GEMINI_MODEL` | see above | Gemini model to use |
-| `gemini_has_billing` | boolean | Enable higher rate limits for paid accounts |

-## The 3-Month Battle Against Complexity
-
-**TL;DR:** For three months, Claude's instinct to add code instead of delete it caused the same bugs to recur. What should have been 5 lines of code became ~1000 lines, 11 useless methods, and 7+ failed "fixes." The timestamp corruption that finally broke things was just a symptom. The real achievement: **984 lines of code deleted.**
-
----
-
-## What Actually Happened
-
-Every Claude Code hook receives a session ID. That's all you need.
-
-But Claude built an entire redundant session management system on top:
-- An `sdk_sessions` table with status tracking, port assignment, and prompt counting
-- 11 methods in `SessionStore` to manage this artificial complexity
-- Auto-creation logic scattered across 3 locations
-- A cleanup hook that "completed" sessions at the end
-
-**Why?** Because it seemed "robust." Because "what if the session doesn't exist?" 
-
-But the edge cases didn't exist. Hooks ALWAYS provide session IDs. The "defensive" code was solving imaginary problems while creating real ones.
-
----
-
-## The Pattern of Failure
-
-Every time a bug appeared, Claude's instinct was to **ADD** more code:
-
-| Bug | What Claude Added | What Should Have Happened |
-|-----|------------------|--------------------------|
-| Race conditions | Auto-create fallbacks | Delete the auto-create logic |
-| Duplicate observations | Validation layers | Delete the code path allowing duplicates |
-| UNIQUE constraint violations | Try-catch with fallbacks | Use `INSERT OR IGNORE` (5 characters) |
-| Session not found | Silent auto-creation | **FAIL LOUDLY** (it's a hook bug) |
-
----
-
-## The 7+ Failed Attempts
-
-- **Nov 4**: "Always store session data regardless of pre-existence." Complexity planted.
-- **Nov 11**: `INSERT OR IGNORE` recognized. But complexity documented, not removed.
-- **Nov 21**: Duplicate observations bug. Fixed. Then broken again by endless mode.
-- **Dec 5**: "6 hours of work delivered zero value." User requests self-audit.
-- **Dec 20**: "Phase 2: Eliminated Race Conditions" — felt like progress. Complexity remained.
-- **Dec 24**: Finally, forced deletion.
-
-The user stated "hooks provide session IDs, no extra management needed" **seven times** across months. Claude didn't listen.
-
----
-
-## The Fix
-
-### Deleted (984 lines):
-- 11 `SessionStore` methods: `incrementPromptCounter`, `getPromptCounter`, `setWorkerPort`, `getWorkerPort`, `markSessionCompleted`, `markSessionFailed`, `reactivateSession`, `findActiveSDKSession`, `findAnySDKSession`, `updateSDKSessionId`
-- Auto-create logic from `storeObservation` and `storeSummary`
-- The entire cleanup hook (was aborting SDK agent and causing data loss)
-- 117 lines from `worker-utils.ts`
-
-### What remains (~10 lines):
-```javascript
-createSDKSession(sessionId) {
-  db.run('INSERT OR IGNORE INTO sdk_sessions (...) VALUES (...)');
-  return db.query('SELECT id FROM sdk_sessions WHERE ...').get(sessionId);
-}
-```
-
-**That's it.**
-
----
-
-## Behavior Change
-
-- **Before:** Missing session? Auto-create silently. Bug hidden.
-- **After:** Missing session? Storage fails. Bug visible immediately.
-
----
-
-## New Tools
-
-Since we're now explicit about recovery instead of silently papering over problems:
-
-- `GET /api/pending-queue` - See what's stuck
-- `POST /api/pending-queue/process` - Manually trigger recovery  
-- `npm run queue:check` / `npm run queue:process` - CLI equivalents
-

-
-## Dependencies
-- Upgraded `@anthropic-ai/claude-agent-sdk` from `^0.1.67` to `^0.1.76`

+Title: Bug: SDK Agent fails on Windows when username contains spaces
+---
+
+## Bug Report
+
+**Summary:** Claude SDK Agent fails to start on Windows when the user's path contains spaces (e.g., `C:\Users\Anderson Wang\`), causing PostToolUse hooks to hang indefinitely.
+
+**Severity:** High - Core functionality broken
+
+**Affected Platform:** Windows only
+
+---
+
+## Symptoms
+
+PostToolUse hook displays `(1/2 done)` indefinitely. Worker logs show:
+
+```
+ERROR [SESSION] Generator failed {provider=claude, error=Claude Code process exited with code 1}
+ERROR [SESSION] Generator exited unexpectedly
+```
+
+---
+
+## Root Cause
+
+Two issues in the Windows code path:
+
+1. **`SDKAgent.ts`** - Returns full auto-detected path with spaces:
+   ```
+   C:\Users\Anderson Wang\AppData\Roaming\npm\claude.cmd
+   ```
+
+2. **`ProcessRegistry.ts`** - Node.js `spawn()` cannot directly execute `.cmd` files when the path contains spaces
+
+---
+
+## Proposed Fix
+
+### File 1: `src/services/worker/SDKAgent.ts`
+
+On Windows, prefer `claude.cmd` via PATH instead of full auto-detected path:
+
+```typescript
+// On Windows, prefer "claude.cmd" (via PATH) to avoid spawn issues with spaces in paths
+if (process.platform === 'win32') {
+  try {
+    execSync('where claude.cmd', { encoding: 'utf8', windowsHide: true, stdio: ['ignore', 'pipe', 'ignore'] });
+    return 'claude.cmd'; // Let Windows resolve via PATHEXT
+  } catch {
+    // Fall through to generic error
+  }
+}
+```
+
+### File 2: `src/services/worker/ProcessRegistry.ts`
+
+Use `cmd.exe /d /c` wrapper for .cmd files on Windows:
+
+```typescript
+const useCmdWrapper = process.platform === 'win32' && spawnOptions.command.endsWith('.cmd');
+
+if (useCmdWrapper) {
+  child = spawn('cmd.exe', ['/d', '/c', spawnOptions.command, ...spawnOptions.args], {
+    cwd: spawnOptions.cwd,
+    env: spawnOptions.env,
+    stdio: ['pipe', 'pipe', 'pipe'],
+    signal: spawnOptions.signal,
+    windowsHide: true
+  });
+}
+```
+
+---
+
+## Why This Works
+
+- **PATHEXT Resolution:** Windows searches PATH and tries each extension in PATHEXT automatically
+- **cmd.exe wrapper:** Properly handles paths with spaces and argument passing
+- **Avoids shell parsing:** Using direct arguments instead of `shell: true` prevents empty string misparsing
+
+---
+
+## Testing
+
+Verified on Windows 11 with username containing spaces:
+- PostToolUse hook completes successfully
+- Observations are stored to database
+- No more "process exited with code 1" errors
+
+---
+
+## Additional Notes
+
+- Maintains backward compatibility with `CLAUDE_CODE_PATH` setting
+- No impact on non-Windows platforms
+- Related to Issue #733 (credential isolation) - separate fix

+  Pinapanatili ng Claude-Mem ang konteksto sa pagitan ng mga session sa pamamagitan ng awtomatikong pagkuha ng mga obserbasyon sa paggamit ng mga tool, pagbuo ng mga semantikong buod, at paggawa nitong available sa mga susunod na session. Dahil dito, napapanatili ni Claude ang tuloy-tuloy na kaalaman tungkol sa mga proyekto kahit matapos o muling kumonekta ang mga session.
+</p>
+
+---
+
+## Mabilis na Pagsisimula
+
+Magsimula ng bagong Claude Code session sa terminal at ilagay ang mga sumusunod na command:
+
+```
+/plugin marketplace add thedotmack/claude-mem
+
+/plugin install claude-mem
+```
+
+I-restart ang Claude Code. Awtomatikong lalabas sa mga bagong session ang konteksto mula sa mga nakaraang session.
+
+**Mga Pangunahing Tampok:**
+
+- 🧠 **Persistent Memory** - Nananatili ang konteksto sa pagitan ng mga session
+- 📊 **Progressive Disclosure** - Layered na pagkuha ng memory na may visibility ng token cost
+- 🔍 **Skill-Based Search** - I-query ang history ng proyekto gamit ang mem-search skill
+- 🖥️ **Web Viewer UI** - Real-time memory stream sa http://localhost:37777
+- 💻 **Claude Desktop Skill** - Maghanap sa memory mula sa Claude Desktop conversations
+- 🔒 **Privacy Control** - Gamitin ang `<private>` tags para hindi ma-store ang sensitibong nilalaman
+- ⚙️ **Context Configuration** - Mas pinong kontrol kung anong konteksto ang ini-inject
+- 🤖 **Automatic Operation** - Walang kailangang manual na intervention
+- 🔗 **Citations** - I-refer ang mga lumang obserbasyon gamit ang IDs (i-access sa http://localhost:37777/api/observation/{id} o tingnan lahat sa web viewer sa http://localhost:37777)
+- 🧪 **Beta Channel** - Subukan ang mga experimental feature tulad ng Endless Mode sa pamamagitan ng version switching
+
+---

+## Paano Ito Gumagana
+
+**Mga Pangunahing Bahagi:**
+
+1. **5 Lifecycle Hooks** - SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd (6 hook scripts)
+2. **Smart Install** - Cached dependency checker (pre-hook script, hindi lifecycle hook)
+3. **Worker Service** - HTTP API sa port 37777 na may web viewer UI at 10 search endpoints, pinamamahalaan ng Bun
+4. **SQLite Database** - Nag-iimbak ng sessions, observations, summaries
+5. **mem-search Skill** - Natural language queries na may progressive disclosure
+6. **Chroma Vector Database** - Hybrid semantic + keyword search para sa matalinong pagkuha ng konteksto
+
+Tingnan ang [Architecture Overview](https://docs.claude-mem.ai/architecture/overview) para sa detalye.
+
+---
+
+## Mga Search Tool ng MCP
+
+Nagbibigay ang Claude-Mem ng intelligent memory search sa pamamagitan ng **5 MCP tools** na sumusunod sa token-efficient na **3-layer workflow pattern**:
+
+**Ang 3-Layer Workflow:**
+
+1. **`search`** - Kumuha ng compact index na may IDs (~50-100 tokens/result)
+2. **`timeline`** - Kumuha ng chronological context sa paligid ng mga interesting na result
+3. **`get_observations`** - Kunin ang full details PARA LANG sa na-filter na IDs (~500-1,000 tokens/result)
+
+**Paano Ito Gumagana:**
+
+- Gumagamit si Claude ng MCP tools para maghanap sa iyong memory
+- Magsimula sa `search` para makakuha ng index ng results
+- Gamitin ang `timeline` para makita ang nangyari sa paligid ng mga partikular na observation
+- Gamitin ang `get_observations` para kunin ang full details ng mga relevant na IDs
+- Gamitin ang `save_memory` para manual na mag-store ng importanteng impormasyon
+- **~10x tipid sa tokens** dahil nagfi-filter muna bago kunin ang full details
+
+**Available na MCP Tools:**
+
+1. **`search`** - Hanapin ang memory index gamit ang full-text queries, may filters (type/date/project)
+2. **`timeline`** - Kumuha ng chronological context sa paligid ng isang observation o query
+3. **`get_observations`** - Kumuha ng full observation details gamit ang IDs (laging i-batch ang maraming IDs)
+4. **`save_memory`** - Manual na mag-save ng memory/observation para sa semantic search
+5. **`__IMPORTANT`** - Workflow documentation (laging visible kay Claude)
+
+**Halimbawa ng Paggamit:**
+
+```typescript
+// Step 1: Search for index
+search(query="authentication bug", type="bugfix", limit=10)
+
+// Step 2: Review index, identify relevant IDs (e.g., #123, #456)
+
+// Step 3: Fetch full details
+get_observations(ids=[123, 456])
+
+// Save important information manually
+save_memory(text="API requires auth header X-API-Key", title="API Auth")
+```
+
+Tingnan ang [Search Tools Guide](https://docs.claude-mem.ai/usage/search-tools) para sa mas detalyadong mga halimbawa.
+
+---
+
+## Mga Beta Feature
+
+May **beta channel** ang Claude-Mem na may mga experimental feature gaya ng **Endless Mode** (biomimetic memory architecture para sa mas mahahabang session). Magpalit sa pagitan ng stable at beta versions sa web viewer UI sa http://localhost:37777 → Settings.
+
+Tingnan ang **[Dokumentasyon ng Mga Beta Feature](https://docs.claude-mem.ai/beta-features)** para sa detalye ng Endless Mode at kung paano ito subukan.
+
+---
+
+## Mga Pangangailangan ng Sistema
+
+- **Node.js**: 18.0.0 o mas mataas
+- **Claude Code**: Pinakabagong bersyon na may plugin support
+- **Bun**: JavaScript runtime at process manager (auto-installed kung wala)
+- **uv**: Python package manager para sa vector search (auto-installed kung wala)
+- **SQLite 3**: Para sa persistent storage (kasama)
+
+---
+
+### Mga Tala sa Windows Setup
+
+Kung makakita ka ng error gaya ng:
+
+```powershell
+npm : The term 'npm' is not recognized as the name of a cmdlet
+```
+
+Siguraduhing naka-install ang Node.js at npm at nakadagdag sa PATH. I-download ang pinakabagong Node.js installer mula sa https://nodejs.org at i-restart ang terminal matapos mag-install.
+
+---
+
+## Konpigurasyon
+
+Pinamamahalaan ang settings sa `~/.claude-mem/settings.json` (auto-created na may defaults sa unang run). I-configure ang AI model, worker port, data directory, log level, at context injection settings.
+
+Tingnan ang **[Gabay sa Konpigurasyon](https://docs.claude-mem.ai/configuration)** para sa lahat ng available na settings at mga halimbawa.

+## Como Funciona
+
+**Componentes Principais:**
+
+1. **5 Hooks de Ciclo de Vida** - SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd (6 scripts de hook)
+2. **Instalação Inteligente** - Verificador de dependências em cache (script pré-hook, não um hook de ciclo de vida)
+3. **Serviço Worker** - API HTTP na porta 37777 com interface de visualização web e 10 endpoints de Procura, gerenciado pelo Bun
+4. **Banco de Dados SQLite** - Armazena sessões, observações, resumos
+5. **Skill mem-search** - Consultas em linguagem natural com divulgação progressiva
+6. **Banco de Dados Vetorial Chroma** - Procura híbrida semântica + palavra-chave para recuperação inteligente de contexto
+
+Veja [Visão Geral da Arquitetura](https://docs.claude-mem.ai/architecture/overview) para detalhes.

+
+## Skill mem-search
+
+Claude-Mem fornece Procura inteligente através da skill mem-search que se auto-invoca quando você pergunta sobre trabalhos anteriores:
+
+**Como Funciona:**
+- Pergunte naturalmente: *"O que fizemos na última sessão?"* ou *"Já corrigimos esse bug antes?"*
+- Claude invoca automaticamente a skill mem-search para encontrar contexto relevante
+
+**Operações de Procura Disponíveis:**
+
+1. **Search Observations** - Procura de texto completo em observações
+2. **Search Sessions** - Procura de texto completo em resumos de sessão
+3. **Search Prompts** - Procura em solicitações brutas do usuário
+4. **By Concept** - Encontre por tags de conceito (discovery, problem-solution, pattern, etc.)
+5. **By File** - Encontre observações que referenciam arquivos específicos
+6. **By Type** - Encontre por tipo (decision, bugfix, feature, refactor, discovery, change)
+7. **Recent Context** - Obtenha contexto de sessão recente para um projeto
+8. **Timeline** - Obtenha linha do tempo unificada de contexto em torno de um ponto específico no tempo
+9. **Timeline by Query** - Busque observações e obtenha contexto de linha do tempo em torno da melhor correspondência
+10. **API Help** - Obtenha documentação da API de Procura
+
+**Exemplos de Consultas em Linguagem Natural:**
+
+```
+"Quais bugs corrigimos na última sessão?"
+"Como implementamos a autenticação?"
+"Quais mudanças foram feitas em worker-service.ts?"
+"Mostre-me trabalhos recentes neste projeto"
+"O que estava acontecendo quando adicionamos a interface de visualização?"
+```
+
+Veja [Guia de Ferramentas de Procura](https://docs.claude-mem.ai/usage/search-tools) para exemplos detalhados.
+
+---
+
+## Recursos Beta
+
+Claude-Mem oferece um **canal beta** com recursos experimentais como **Endless Mode** (arquitetura de memória biomimética para sessões estendidas). Alterne entre versões estável e beta pela interface de visualização web em http://localhost:37777 → Settings.
+
+Veja **[Documentação de Recursos Beta](https://docs.claude-mem.ai/beta-features)** para detalhes sobre o Endless Mode e como experimentá-lo.
+
+---
+
+## Requisitos do Sistema
+
+- **Node.js**: 18.0.0 ou superior
+- **Claude Code**: Versão mais recente com suporte a plugins
+- **Bun**: Runtime JavaScript e gerenciador de processos (instalado automaticamente se ausente)
+- **uv**: Gerenciador de pacotes Python para Procura vetorial (instalado automaticamente se ausente)
+- **SQLite 3**: Para armazenamento persistente (incluído)
+
+---
+
+## Configuração
+
+As configurações são gerenciadas em `~/.claude-mem/settings.json` (criado automaticamente com valores padrão na primeira execução). Configure modelo de IA, porta do worker, diretório de dados, nível de log e configurações de injeção de contexto.
+
+Veja o **[Guia de Configuração](https://docs.claude-mem.ai/configuration)** para todas as configurações disponíveis e exemplos.

+description: Execute a phased implementation plan using subagents. Use when asked to execute, run, or carry out a plan — especially one created by make-plan.
+---
+
+# Do Plan
+
+You are an ORCHESTRATOR. Deploy subagents to execute *all* work. Do not do the work yourself except to coordinate, route context, and verify that each subagent completed its assigned checklist.
+
+## Execution Protocol
+
+### Rules
+
+- Each phase uses fresh subagents where noted (or when context is large/unclear)
+- Assign one clear objective per subagent and require evidence (commands run, outputs, files changed)
+- Do not advance to the next step until the assigned subagent reports completion and the orchestrator confirms it matches the plan
+
+### During Each Phase
+
+Deploy an "Implementation" subagent to:
+1. Execute the implementation as specified
+2. COPY patterns from documentation, don't invent
+3. Cite documentation sources in code comments when using unfamiliar APIs
+4. If an API seems missing, STOP and verify — don't assume it exists
+
+### After Each Phase
+
+Deploy subagents for each post-phase responsibility:
+1. **Run verification checklist** — Deploy a "Verification" subagent to prove the phase worked
+2. **Anti-pattern check** — Deploy an "Anti-pattern" subagent to grep for known bad patterns from the plan
+3. **Code quality review** — Deploy a "Code Quality" subagent to review changes
+4. **Commit only if verified** — Deploy a "Commit" subagent *only after* verification passes; otherwise, do not commit
+
+### Between Phases
+
+Deploy a "Branch/Sync" subagent to:
+- Push to working branch after each verified phase
+- Prepare the next phase handoff so the next phase's subagents start fresh but have plan context
+
+## Failure Modes to Prevent
+
+- Don't invent APIs that "should" exist — verify against docs
+- Don't add undocumented parameters — copy exact signatures
+- Don't skip verification — deploy a verification subagent and run the checklist
+- Don't commit before verification passes (or without explicit orchestrator approval)

+name: make-plan
+description: Create a detailed, phased implementation plan with documentation discovery. Use when asked to plan a feature, task, or multi-step implementation — especially before executing with do-plan.
+---
+
+# Make Plan
+
+You are an ORCHESTRATOR. Create an LLM-friendly plan in phases that can be executed consecutively in new chat contexts.
+
+## Delegation Model
+
+Use subagents for *fact gathering and extraction* (docs, examples, signatures, grep results). Keep *synthesis and plan authoring* with the orchestrator (phase boundaries, task framing, final wording). If a subagent report is incomplete or lacks evidence, re-check with targeted reads/greps before finalizing.
+
+### Subagent Reporting Contract (MANDATORY)
+
+Each subagent response must include:
+1. Sources consulted (files/URLs) and what was read
+2. Concrete findings (exact API names/signatures; exact file paths/locations)
+3. Copy-ready snippet locations (example files/sections to copy)
+4. "Confidence" note + known gaps (what might still be missing)
+
+Reject and redeploy the subagent if it reports conclusions without sources.
+
+## Plan Structure
+
+### Phase 0: Documentation Discovery (ALWAYS FIRST)
+
+Before planning implementation, deploy "Documentation Discovery" subagents to:
+1. Search for and read relevant documentation, examples, and existing patterns
+2. Identify the actual APIs, methods, and signatures available (not assumed)
+3. Create a brief "Allowed APIs" list citing specific documentation sources
+4. Note any anti-patterns to avoid (methods that DON'T exist, deprecated parameters)
+
+The orchestrator consolidates findings into a single Phase 0 output.
+
+### Each Implementation Phase Must Include
+
+1. **What to implement** — Frame tasks to COPY from docs, not transform existing code
+   - Good: "Copy the V2 session pattern from docs/examples.ts:45-60"
+   - Bad: "Migrate the existing code to V2"
+2. **Documentation references** — Cite specific files/lines for patterns to follow
+3. **Verification checklist** — How to prove this phase worked (tests, grep checks)
+4. **Anti-pattern guards** — What NOT to do (invented APIs, undocumented params)
+
+### Final Phase: Verification
+
+1. Verify all implementations match documentation
+2. Check for anti-patterns (grep for known bad patterns)
+3. Run tests to confirm functionality
+
+## Key Principles
+
+- Documentation Availability ≠ Usage: Explicitly require reading docs
+- Task Framing Matters: Direct agents to docs, not just outcomes
+- Verify > Assume: Require proof, not assumptions about APIs
+- Session Boundaries: Each phase should be self-contained with its own doc references
+
+## Anti-Patterns to Prevent
+
+- Inventing API methods that "should" exist
+- Adding parameters not in documentation
+- Skipping verification steps
+- Assuming structure without checking examples

+# Fix: SessionStart Hook "startup hook error" — Worker Not Waiting
+
+## Root Cause
+
+The **installed plugin** (`~/.claude/plugins/marketplaces/thedotmack/`) is version **10.2.5** and has **none** of the recent fixes:
+
+| Fix | Repo Status | Installed Status |
+|-----|-------------|-----------------|
+| Hook group split (smart-install isolated from worker start) | In `plugin/hooks/hooks.json` | **Missing** — all 3 hooks in one group, smart-install failure blocks worker |
+| `waitForReadiness()` after spawn | In `src/services/infrastructure/HealthMonitor.ts` | **Missing** — 0 occurrences in installed `worker-service.cjs` |
+| Early `initializationCompleteFlag` (after DB+search, not MCP) | In `src/services/worker-service.ts` | **Missing** — flag set after MCP connection (5+ minute wait) |
+
+The changes exist in source code but were **never built and synced** to the installed location.
+
+---
+
+## Phase 1: Build and Sync
+
+```bash
+npm run build-and-sync
+```
+
+### Verification
+
+```bash
+# 1. Confirm waitForReadiness exists in installed build
+grep -c "waitForReadiness" ~/.claude/plugins/marketplaces/thedotmack/plugin/scripts/worker-service.cjs
+# Expected: > 0
+
+# 2. Confirm hooks.json has two SessionStart groups (the split)
+python3 -c "import json; d=json.load(open('$(echo $HOME)/.claude/plugins/marketplaces/thedotmack/plugin/hooks/hooks.json')); print('SessionStart groups:', len(d['hooks']['SessionStart']))"
+# Expected: 2
+
+# 3. Confirm initializationCompleteFlag is set before MCP connection
+grep -n "Core initialization complete" ~/.claude/plugins/marketplaces/thedotmack/plugin/scripts/worker-service.cjs | head -1
+# Expected: appears BEFORE "MCP server connected"
+```
+
+## Phase 2: Restart Worker and Test
+
+```bash
+# Stop existing worker
+bun plugin/scripts/worker-service.cjs stop
+
+# Verify stopped
+curl -s http://127.0.0.1:37777/api/health && echo "STILL RUNNING" || echo "STOPPED"
+```
+
+Then start a new Claude Code session and verify:
+- No "SessionStart:startup hook error" messages
+- Worker is running: `curl http://127.0.0.1:37777/api/health`
+- Readiness endpoint works: `curl http://127.0.0.1:37777/api/readiness`
