SynthesisAgent.OpenclawPlugin

The OpenClaw side of SynthesisAgent. Lives inside the OpenClaw process; spawns and manages one long-lived interactive claude per OpenClaw session.

Components

index.ts                 entry: definePluginEntry, wires up the others
core/config.ts           plugin config schema + defaults
core/session-mapping.ts  persistent openclaw_session ↔ claude_session_uuid
core/process-manager.ts  spawn/resume/kill claude processes
core/cli.ts              admin commands (`openclaw synthesis ...`)
web/bridge-server.ts     WebSocket server that ClaudePlugins connect into

Lifecycle

plugin loaded
  ↓
SessionMapping reads ~/.openclaw/synthesis/sessions.json
ProcessManager idle, no spawns yet
BridgeServer binds 127.0.0.1:18801
  ↓
inbound Discord msg for session=alice
  ↓
processManager.ensure('alice')
  - mapping.ensure → claude_session_uuid (new or existing)
  - spawn `claude --channels plugin:synthesis-claude@local --resume <uuid> ...`
  - inject env: SYNTHESIS_BRIDGE_URL / TOKEN / OPENCLAW_SESSION / CLAUDE_SESSION
  ↓
ClaudePlugin (in spawned claude) dials ws://127.0.0.1:18801/bridge
  - sends hello frame
  - server validates token, marks process ready, sends hello_ack with tool catalog
  ↓
processManager.ensure resolves
inbound message pushed → notifications/claude/channel → Claude starts new turn
  ↓
Claude calls tools/call → forwarded to OpenClaw tool surface
Claude finishes → process stays alive, idle timer reset
  ↓
1 hour idle → idleSweeper SIGTERMs the process
mapping is preserved → next message resumes via --resume

Config

See openclaw.plugin.json configSchema. Override in ~/.openclaw/openclaw.json:

{
  "plugins": {
    "entries": {
      "synthesis-agent": {
        "bridgePort": 18801,
        "bridgeToken": "<random secret>",
        "idleKillMs": 1800000,
        "maxProcesses": 8
      }
    }
  }
}

TODO

• Discover exact OpenClaw plugin-sdk API for: inbound event subscription, CLI command registration, tool catalog enumeration. See contractor-agent/index.ts for current best example.
• Wire api.channels.onInbound(...) to pm.ensure() + bridgeServer.pushInbound().
• Implement tool dispatch in web/bridge-server.ts (current tool_call handler returns not-implemented).
• Implement permission routing back to source channel.
• CLI: openclaw synthesis list, push, kill, forget.
• Settle path conflict: this plugin needs to live at /root/.openclaw/plugins/synthesis-agent/ to be auto-loaded. Either symlink from this repo or document copy-install.
• Decide policy on --no-session-persistence flag (currently we rely on default persistence so --resume works).
