Python starters were trying to run uvicorn with agent.<module>:app but those modules don't export a FastAPI app. The demo packages use agent_server.py as the FastAPI wrapper, so starters need it too. Changes: - Copy agent_server.py from each demo package into starter root, rewriting "from agents." to "from agent." for the starter layout - Update all non-langgraph Python devScripts to use agent_server:app - Update Dockerfile.python to COPY agent_server.py for non-langgraph - Update getEntrypointBlock() generic Python to use agent_server:app - Make langgraph-fastapi use langgraph_cli dev like langgraph-python (it was incorrectly configured as a uvicorn-based starter) - Regenerate all starters

Agent Server for Langroid
|
|
|
|
FastAPI server that hosts the Langroid agent backend.
|
|
The Next.js CopilotKit runtime proxies requests here via AG-UI protocol.
|
|
|
|
Langroid does not have a native AG-UI adapter, so we implement a custom
|
|
SSE endpoint that translates between Langroid's ChatAgent and the AG-UI
|
|
event stream.
