Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@min202299/claude-mem

v13.0.1

Published

Memory compression system for Claude Code - persist context across sessions (fork with custom AI provider support)

Readme


Fork notice: This is a fork of thedotmack/claude-mem that adds custom AI provider support (any OpenAI-compatible API as the LLM backend — see Custom Provider Configuration). It is published on npm as @min202299/claude-mem, so the install commands below use that scoped package name.

Quick Start

Install with a single command:

npx @min202299/claude-mem install

Or install for Gemini CLI (auto-detects ~/.gemini):

npx @min202299/claude-mem install --ide gemini-cli

Or install for OpenCode:

npx @min202299/claude-mem install --ide opencode

Or install from the plugin marketplace inside Claude Code:

/plugin marketplace add MIN202299/claude-mem

/plugin install claude-mem

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

Note: The package is also importable as an SDK/library, but npm install -g @min202299/claude-mem installs the SDK/library only — it does not register the plugin hooks or set up the worker service. Always install via npx @min202299/claude-mem install or the /plugin commands above.

Once installed, the CLI command itself is still claude-mem (e.g. npx @min202299/claude-mem start, npx @min202299/claude-mem status).

🦞 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.

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
  • 🔌 Custom Provider - Use any OpenAI-compatible API (Ollama, vLLM, Together AI, LiteLLM) as the LLM backend

Getting Started

Best Practices

Architecture

Configuration & Development


How It Works

Core Components:

  1. 5 Lifecycle Hooks - SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd (6 hook scripts)
  2. Smart Install - Cached dependency checker (pre-hook script, not a lifecycle hook)
  3. Worker Service - HTTP API on port 37777 with web viewer UI and 10 search endpoints, managed by Bun
  4. SQLite Database - Stores sessions, observations, summaries
  5. mem-search Skill - Natural language queries with progressive disclosure
  6. 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:

  1. search - Get compact index with IDs (~50-100 tokens/result)
  2. timeline - Get chronological context around interesting results
  3. 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:

  1. search - Search memory index with full-text queries, filters by type/date/project
  2. timeline - Get chronological context around a specific observation or query
  3. get_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.


Beta Features

Claude-Mem offers a beta channel with experimental features like Endless Mode (biomimetic memory architecture for extended sessions). Switch between stable and beta versions from the web viewer UI at http://localhost:37777 → Settings.

See Beta Features Documentation for details on Endless Mode and how to try it.


System Requirements

  • Node.js: 18.0.0 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.


Custom Provider Configuration

Claude-Mem supports any OpenAI-compatible API as the LLM backend for observation extraction, including Ollama, vLLM, Together AI, DeepInfra, and LiteLLM.

How to Configure

Edit your settings file at ~/.claude-mem/settings.json:

{
  "CLAUDE_MEM_CUSTOM_BASE_URL": "http://localhost:11434/v1",
  "CLAUDE_MEM_CUSTOM_API_KEY": "",
  "CLAUDE_MEM_CUSTOM_MODEL": "llama-3.1-8b",
  "CLAUDE_MEM_CUSTOM_DISPLAY_NAME": "Ollama",
  "CLAUDE_MEM_CUSTOM_MAX_CONTEXT_MESSAGES": "20",
  "CLAUDE_MEM_CUSTOM_MAX_TOKENS": "100000"
}

| Setting | Description | |---|---| | CLAUDE_MEM_CUSTOM_BASE_URL | Base URL of the OpenAI-compatible API (required) | | CLAUDE_MEM_CUSTOM_API_KEY | API key for authenticated providers (optional) | | CLAUDE_MEM_CUSTOM_MODEL | Model name to use (required, e.g. llama-3.1-8b) | | CLAUDE_MEM_CUSTOM_DISPLAY_NAME | Display name shown in the UI (default: Custom) | | CLAUDE_MEM_CUSTOM_MAX_CONTEXT_MESSAGES | Max messages in context window (default: 20) | | CLAUDE_MEM_CUSTOM_MAX_TOKENS | Max estimated token safety limit (default: 100000) |

You can also configure these settings through the web viewer UI at http://localhost:37777 → Settings.

Examples

Ollama (local):

{
  "CLAUDE_MEM_CUSTOM_BASE_URL": "http://localhost:11434/v1",
  "CLAUDE_MEM_CUSTOM_MODEL": "llama-3.1-8b"
}

Together AI:

{
  "CLAUDE_MEM_CUSTOM_BASE_URL": "https://api.together.xyz/v1",
  "CLAUDE_MEM_CUSTOM_API_KEY": "your-api-key",
  "CLAUDE_MEM_CUSTOM_MODEL": "meta-llama/Llama-3.1-70B-Instruct-Turbo"
}

LiteLLM proxy:

{
  "CLAUDE_MEM_CUSTOM_BASE_URL": "http://localhost:4000",
  "CLAUDE_MEM_CUSTOM_MODEL": "your-model-name"
}

After configuring, select the custom provider in the Viewer UI or set CLAUDE_MEM_CUSTOM_BASE_URL to enable automatic fallback.
