Failure Patterns Prevented for Python FastAPI

Without This Rule (Default LLM Behavior)Vulnerable

Instructs Claude on Python virtualenv activation, poetry/uv/pip commands, pytest execution, and async conventions.

Hallucination Symptoms
  • Invokes deprecated or removed APIs from older model training weights
  • Generates conflicting configuration files and invalid imports
  • Silently drops type-safety, boundaries, or transaction isolation
With This Rule (Guaranteed Invariants)Deterministic
Specify virtual environment and dependency runner commands (`uv run pytest`, `uv run uvicorn`).
Document layered architecture: api/, services/, models/, core/.
Enforce Pydantic v2 data validation standards.
