What problem does it solve?

The Python FastAPI Review Skill automatically checks Python codebase in FastAPI projects for async pitfalls, validation gaps, ORM mistakes, and security vulnerabilities.

Core Features & Use Cases

  • Review async issues: Identifies blocking calls in async handlers, missing 'await' usages, and sync/db session mismatches.
  • Pydantic model validation: Validates trust boundaries, model consistency, and data structure integrity.
  • ORM and SQL checks: Identifies raw SQL queries, N+1 patterns, and improper session handling.
  • Security checks: Alerts for command injection, path traversal, eval/exec usages, CORS issues, and authorization bypasses.
  • Error and logging: Ensures structured error handling and logs on recoverable errors.

Quick Start

To perform a review, execute the 'python-fastapi-review' skill on any Python .py file in a FastAPI service.

FAQPage Schema
How do I find blocking calls and missing await statements in async FastAPI handlers?

To find blocking calls in async FastAPI handlers, use automated code review to identify missing 'await' usages and sync/db session mismatches. This detects asynchronous programming errors that degrade API concurrency and performance.

What is the best way to check Pydantic models for data validation gaps in FastAPI?

The best way to check Pydantic models for data validation gaps is running an automated review that validates trust boundaries, model consistency, and data structure integrity. This ensures request parsing securely enforces application constraints.

Can I detect N+1 query patterns and raw SQL issues in async ORM sessions?

Yes, you can detect N+1 query patterns and raw SQL issues in async ORM sessions. Automated review identifies ORM misuse, raw SQL queries, and improper session handling to prevent database performance bottlenecks.

Does FastAPI code review cover security vulnerabilities like command injection and CORS issues?

FastAPI code review covers security vulnerabilities including command injection, path traversal, eval/exec usages, CORS issues, and authorization bypasses. It audits API security by checking request handling and execution paths.

How do I review FastAPI code for structured error handling and logging on recoverable errors?

To review FastAPI code for structured error handling and logging on recoverable errors, run an automated check that ensures structured error responses and logs are properly configured. This maintains application reliability during runtime exceptions.
