Bridge between OpenClaw (multi-channel hub) and interactive Claude Code, keeping autonomous agent usage on the subscription quota after the 2026-06-15 Agent SDK credit split. Initial scaffolding only — two submodules with skeletons: - SynthesisAgent.ClaudePlugin: stdio MCP server registered as a --channels source. Declares experimental.claude/channel capability (verified 2026-05-14 against the official Anthropic discord plugin) and emits notifications/claude/channel to push OpenClaw inbound messages into the Claude turn loop. - SynthesisAgent.OpenclawPlugin: process manager + session mapping + bridge WebSocket. Currently shaped around a custom ws protocol; will be rewritten as a model-provider HTTP server (contractor-agent pattern) so OpenClaw routes inbound channel messages through it via /v1/chat/completions. See STATUS.md for the open punch list and docs/wire-protocol.md for the (soon-to-change) inter-plugin frame schema.
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/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.tsfor current best example. - Wire
api.channels.onInbound(...)topm.ensure()+bridgeServer.pushInbound(). - Implement tool dispatch in
web/bridge-server.ts(currenttool_callhandler 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-persistenceflag (currently we rely on default persistence so--resumeworks).
