Orchestration State 4

Related plan: Orchestration Plan 4

  • ✅ Task 1 — Create the Spawn MCP Server
    • ✅ Create mcp-servers/forge-spawn/ directory
    • ✅ Initialize TypeScript project: package.json, tsconfig.json
    • ✅ Install dependencies: @modelcontextprotocol/sdk, eventsource, dotenv, @paralleldrive/cuid2, pg
    • ✅ Create src/index.ts — MCP server using Stdio transport
    • ✅ Create src/auth.ts — AuthManager (reuse pattern from orchestrator)
    • ✅ Create src/chat-client.ts — ChatClient (reuse pattern from orchestrator)
    • ✅ Create src/db.ts — Database helper (reuse pattern from orchestrator)
    • ✅ Create src/ids.ts — Cuid2 ID generation (reuse pattern from orchestrator)
    • ✅ Register spawn_agent tool with parameters per Spec §4.1
    • ✅ Add MCP server to librechat.yaml
  • ✅ Task 2 — Implement Disconnect Mode
    • ✅ In spawn_agent handler: when mode === "disconnect", invoke agent + create AgentJob
    • ✅ Add check_job tool (query by job_id or conversation_id)
    • ❎ Test: spawn in disconnect mode → job created → poll until completion
      • ✅ Agent runs and responds correctly
      • ✅ Auto-completion works: check_job detects liveStatus.active=false → marks completed
      • ✅ E2E verified 2026-04-28: spawned general-purpose, job auto-completed in ~17s
  • Task 3 — Implement Ralph Wiggum Monitor
    • ✅ In spawn_agent handler: when mode === "monitor", subscribe to SSE stream
    • ✅ Track tool calls, token progress, completion, last event timestamp
    • ✅ Stall detection: no events for max_duration_seconds
    • ✅ Intervention: abort → restart (fresh or same conversation) per Spec §5.2
    • ✅ Missing required tool check after completion
    • ✅ Max retries (default: 3) → [BLOCKED] in Erik_Todo.md
    • ✅ Context-is-cache principle: rely on filesystem state, not accumulated context
    • ✅ End-to-end test: monitor mode → agent runs → monitor tracks → completion detected
      • ✅ SSE event handling fix confirmed: generic ‘message’ type with embedded event field works
      • ✅ onFinal/onError race fix confirmed: state.completed prevents false error handling
      • ✅ E2E verified 2026-04-28: spawned agent_69d69e3198cb9ee870cd0373 (Forge GLM 5.1), monitor detected completion in ~23s
      • Note: ‘general-purpose’ agent_id fails with ‘missing_model’ SSE error; use concrete agent IDs
  • ✅ Task 4 — Deploy forge-spawn MCP to Railway
    • [x]v Create Dockerfile for spawn MCP server
    • ✅ Add to Railway as stdio MCP in librechat.yaml (same pattern as forge-discovery)
    • ✅ Set env vars: LIBRECHAT_URL, LIBRECHAT_EMAIL, LIBRECHAT_PASSWORD, FORGE_DB_URL
    • ✅ Verify MCP server connects and spawn_agent tool appears
      • ✅ Confirmed: forge-spawn connects, all 3 tools visible (spawn_agent, check_job, abort_job)
    • End-to-end test: disconnect mode → agent runs → check job status
      • ✅ Verified 2026-04-28: disconnect mode job auto-completes correctly
    • End-to-end test: monitor mode → agent runs → monitor tracks → completion detected
      • ✅ Verified 2026-04-28: monitor mode detects completion correctly
