Raw tool I/O had no durable home. `pending_messages` is the generation queue -- rows are claimed, summarized, and deleted -- so once an observation existed the original tool_input/tool_response were gone. Adds `tool_uses` (schema v51) as a by-reference side index for those bodies, written from the one ingest choke point both the PostToolUse hook route and the transcript-watch processor already share. The JSONL transcripts and `src/services/transcripts/*` remain the spine and are untouched. Schema (Receipt freeze 2026-09-06): UNIQUE(content_session_id, tool_use_id), nullable `or_generation_id` / `or_session_id` as join keys back to an OpenRouter spend line, and deliberately no cost_usd/micros -- this table carries tool identity, dollars stay on the OR stamp. No FK on session_db_id/observation_id: a FK there can abort the constructor migration chain (#3378), and observation_id is linked late by design. Write path dual-writes alongside -- never instead of -- the pending_messages enqueue, and swallows its own failures so an observation is never lost to a backup-index error. `toolUseId` now actually reaches the worker from hooks: it was missing from NormalizedHookInput and every hook adapter, so only the transcript path supplied it. ResponseProcessor links the batch's claimed ids to the first stored observation. Read path is progressive-disclosure layer 4: POST /api/tool-uses/batch requires explicit ids (never a full-table scan), GET /api/tool-uses returns a cheap index shape with size hints and never the payloads, and the `get_tool_uses` MCP tool is described as a last resort. claude-mem's own read tools are skipped by the writer -- without that, every call to get_tool_uses would store the bodies it just returned. Payloads are stored in-row with a 64 KB soft cap and a UTF-8-safe truncation marker; content_hash is computed over the original.

Grok Mem is how Grok Bots remember the work. Grok already remembers you. Grok Mem remembers what the bot did, what we decided, what to do next. Those notes come back in the next chat.
Quick Start
Install Grok Mem for Grok Bot. The package name is still claude-mem.
npx claude-mem install --ide grok-bot
Grok Bot has no host hooks, so we watch the chat log files. Default is CMEM Pro, the hosted memory. Local observer is opt-in: --provider host. Installing this plugin does not install Cursor.
Install with a single command:
npx claude-mem install
The installer sets everything up first, then asks you to sign in to claude-mem in your browser (email magic link — no card required). Signing in provisions a memory key for your account and unlocks the claude-mem observer: memory that runs off-plan, free for your first 30 days, so you get up to 100% more usage from your plan. When the free trial ends, memory automatically falls back to your Anthropic plan unless you subscribe. After sign-in you pick your memory provider — the claude-mem observer, your own OpenRouter or Gemini key, or your Anthropic plan.
Prefer to skip the sign-in? Pass an explicit --provider flag, set CLAUDE_MEM_ONLINE_OPTIN=false, or run in CI/non-interactive shells — the installer completes without any account interaction.
Or install for OpenCode:
npx claude-mem install --ide opencode
Or install for Antigravity CLI (setup guide):
npx claude-mem install --ide antigravity
Or install from the plugin marketplace inside Claude Code:
/plugin marketplace add thedotmack/claude-mem
/plugin install claude-mem
Restart Claude Code. Context from previous sessions will automatically appear in new sessions.
Note: Claude-Mem is also published on npm, but
npm install -g claude-meminstalls the SDK/library only — it does not register the plugin hooks or set up the worker service. Always install vianpx claude-mem installor the/plugincommands above.
🦞 OpenClaw Gateway
Install claude-mem as a persistent memory plugin on OpenClaw gateways with a single command:
curl -fsSL https://install.cmem.ai/openclaw.sh | bash
The installer handles dependencies, plugin setup, AI provider configuration, worker startup, and optional real-time observation feeds to Telegram, Discord, Slack, and more. See the OpenClaw Integration Guide for details.

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 - Local HTTP API with web viewer UI and 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 resultsget_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
searchto get an index of results - Use
timelineto see what was happening around specific observations - Use
get_observationsto 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/projecttimeline- Get chronological context around a specific observation or queryget_observations- Fetch full observation details by IDs (always batch multiple IDs)
Example Usage:
// 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])
See Search Tools Guide for detailed examples.
Release Branches
Stable releases ship from main and are published to npm. core-dev and
community-edge are source-run branches for early reliability fixes and
community integrations. See Release Branches
for the branch flow and non-stable run instructions.
System Requirements
- Node.js: 20.0.0 or higher
- Claude Code: Latest version with plugin support
- Bun: JavaScript runtime and process manager (auto-installed if missing)
- uv: Python package manager for vector search (auto-installed if missing)
- SQLite 3: For persistent storage (bundled)
Windows Setup Notes
If you see an error like:
npm : The term 'npm' is not recognized as the name of a cmdlet
Make sure Node.js and npm are installed and added to your PATH. Download the latest Node.js installer from https://nodejs.org and restart your terminal after installation.
Configuration
Settings are managed in ~/.claude-mem/settings.json (auto-created with defaults on first run). Configure AI model, worker port, data directory, log level, and context injection settings.
See the Configuration Guide for all available settings and examples.
Mode & Language Configuration
Claude-Mem supports multiple workflow modes and languages via the CLAUDE_MEM_MODE setting.
This option controls both:
- The workflow behavior (e.g. code, chill, investigation)
- The language used in generated observations
How to Configure
Edit your settings file at ~/.claude-mem/settings.json:
{
"CLAUDE_MEM_MODE": "code--zh"
}
Modes are defined in plugin/modes/. To see all available modes locally:
ls ~/.claude/plugins/marketplaces/thedotmack/plugin/modes/
Available Modes
| Mode | Description |
|---|---|
code |
Default English mode |
code--zh |
Simplified Chinese mode |
code--ja |
Japanese mode |
Language-specific modes follow the pattern code--[lang] where [lang] is the ISO 639-1 language code (e.g., zh for Chinese, ja for Japanese, es for Spanish).
Note:
code--zh(Simplified Chinese) is already built-in — no additional installation or plugin update is required.
After Changing Mode
Restart Claude Code to apply the new mode configuration.
