LinkMind Context Engine Plugin for OpenClaw

linkmind-context is a native OpenClaw plugin that registers a custom context engine via api.registerContextEngine(id, factory). It compacts long conversation history by sending the current session messages to the LinkMind API and can be selected through plugins.slots.contextEngine.

Repository: landingbj/linkmind-context

Features

• Registers a native OpenClaw context engine named linkmind-context
• Triggers compaction when the accumulated context exceeds a configurable threshold
• Calls POST /openclaw/compress on the LinkMind service
• Supports optional bearer-token authentication
• Keeps the plugin configuration validated through openclaw.plugin.json

Requirements

• Node.js 22 or newer
• OpenClaw with plugin support enabled
• A reachable LinkMind service endpoint

Install for Local Development

npm install
npm run build
openclaw plugins install .

After installing, restart the OpenClaw gateway so the plugin can be discovered and loaded.

Install from a Published Package

Once the package is published, users can install it with:

openclaw plugins install linkmind-context

OpenClaw checks ClawHub first and falls back to npm automatically.

OpenClaw Configuration

Configure the plugin in your OpenClaw config file and select it as the active context engine:

{
  "plugins": {
    "slots": {
      "contextEngine": "linkmind-context"
    },
    "entries": {
      "linkmind-context": {
        "enabled": true,
        "config": {
          "apiUrl": "http://localhost:8080/v1",
          "apiKey": "",
          "compressionThreshold": 1000,
          "debug": false
        }
      }
    }
  }
}

Configuration Reference

LinkMind API Contract

The plugin calls this endpoint:

POST /v1/openclaw/compress
Content-Type: application/json
Authorization: Bearer <token>

Example request body:

{
  "sessionId": "session-123",
  "messages": [],
  "tokenBudget": 128000,
  "currentTokenCount": 2048
}

Expected response shape:

{
  "status": "success",
  "messages": [],
  "tokensBefore": 2048,
  "tokensAfter": 768
}

If status is not success, the plugin treats the response as a compaction failure and keeps the original context.

Publish Checklist

• package.json includes openclaw.extensions
• openclaw.plugin.json exists at the package root
• The published tarball includes dist/, README.md, and openclaw.plugin.json
• Source code is hosted publicly on GitHub
• This README documents installation and configuration

Development Notes

• Build output is emitted to dist/
• npm pack and npm publish will run npm run build first through prepack
• For a production release, publish the package, then submit it to the OpenClaw community plugin list with the package name, repository URL, description, and install command
