FAQPage Schema
How do I review FastAPI routing for code quality issues?

Code review for FastAPI routing checks APIRouter setup, response models, status codes, and HTTP methods. This Skill automatically identifies missing explicit response models, incorrect status codes, and improperly configured routes to catch anti-patterns before deployment.

What's the best way to validate FastAPI dependency injection?

Validate FastAPI dependency injection by verifying Depends() usage, proper cleanup with yield statements, and correct lifecycle management. This Skill catches improper dependency configuration and missing cleanup handlers that can leak resources.

How do I ensure my FastAPI handlers use async patterns correctly?

Ensure async patterns in FastAPI by checking non-blocking I/O, proper async/await usage in route handlers, and avoiding blocking operations. This Skill detects async anti-patterns and validates that handlers follow asynchronous best practices.

Can I automate FastAPI validation and error handling checks?

Automate validation and error handling checks using code review that enforces consistent HTTPException handling, Pydantic model validation, and proper error responses. This Skill applies these checks across your FastAPI project automatically for CI pipelines.

What does a FastAPI code review check in routing and dependencies?

A FastAPI code review examines APIRouter configuration, Depends() injection patterns, Pydantic validation, async handlers, HTTPException usage, and response model definitions. It catches common anti-patterns that affect performance, reliability, and maintainability.
