 Several agents diverge significantly from the standard pattern:
 
-**langflow/templates/simple_tool_calling_agent** - Podman Compose flow-import deployment, not standalone FastAPI. No Dockerfile, pyproject.toml, main.py, src/, or tests/. Different Makefile targets (`init`, `ollama`, `run`, `stop`, `clean`). Uses infra-only env vars (PostgreSQL, Langfuse, Ollama) -- not `API_KEY`/`BASE_URL`/`MODEL_ID`.
