What

src/timmy_serve/app.py line 104: timmy = create_timmy() is called on every /serve/chat POST request, recreating the agent each time.

Why

If create_timmy() involves any setup (config, memory, backend init), this adds unnecessary latency per request.

Acceptance criteria

  • Cache the Timmy agent at app startup (in lifespan) or use a lazy singleton
  • Ensure async safety if the agent is shared
  • Unit test verifying single instance
