# MACP OpenClaw Plugin

This plugin registers a new OpenClaw ACP runtime backend named `macp`.

When OpenClaw calls `sessions_spawn(runtime: "macp")`, the plugin now writes the prompt to a brief file, queues a MACP controller task in `.mosaic/orchestrator/tasks.json`, triggers `mosaic-orchestrator-run --once`, polls `.mosaic/orchestrator/results/<task-id>.json`, and streams the resulting output back as ACP runtime events.

## Current behavior

- Supports ACP `mode: "oneshot"` only
- Accepts any `agentId` and maps it to the queued MACP task `runtime`
- Defaults queued tasks to `dispatch: "yolo"` and `runtime: "codex"` when no override is provided
- Rejects persistent ACP sessions
- Keeps `src/pi-bridge.ts` for future `dispatch: "pi"` support

## Install in OpenClaw

Add the plugin entry to your OpenClaw config:

```json
{
  "plugins": ["~/src/mosaic-mono-v1/plugins/macp/src/index.ts"]
}
```

## Optional config

```json
{
  "plugins": [
    {
      "source": "~/src/mosaic-mono-v1/plugins/macp/src/index.ts",
      "config": {
        "defaultModel": "openai/gpt-5-mini",
        "systemPrompt": "You are Pi running via MACP.",
        "timeoutMs": 300000,
        "logDir": "~/.openclaw/state/macp",
        "repoRoot": "~/src/mosaic-mono-v1",
        "orchDir": "~/src/mosaic-mono-v1/.mosaic/orchestrator",
        "defaultDispatch": "yolo",
        "defaultRuntime": "codex"
      }
    }
  ]
}
```

## Runtime flow

1. OpenClaw ensures a oneshot `macp` session and preserves the requested `agentId`.
2. `runTurn` writes the turn prompt to `~/.mosaic/macp-oc/<session>-<request>.md`.
3. The plugin appends a pending MACP task to the configured orchestrator queue.
4. The plugin triggers `~/.config/mosaic/bin/mosaic-orchestrator-run --once` in the configured repo root.
5. The plugin polls for `.mosaic/orchestrator/results/<task-id>.json` and streams the result back to OpenClaw.

## Verification

```bash
pnpm --filter @mosaic/oc-macp-plugin typecheck || npx tsc --noEmit -p plugins/macp/tsconfig.json
pnpm prettier --write "plugins/macp/**/*.{ts,json,md}"
pnpm format:check
```
