Failure Patterns Prevented for Python FastAPI & AI

Without This Rule (Default LLM Behavior)Vulnerable

Teaches Claude Code how to scaffold, debug, and optimize Python FastAPI backends using Pydantic v2 and async database sessions.

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
Enforce Pydantic v2 BaseModels with Field constraints.
Validate async non-blocking operations across all route handlers.
Handle domain errors gracefully at service boundary.
