Lint Python Skill
This skill allows you to maintain the quality and type safety of the FastAPI backend project using Astral's high-performance tools: ruff and ty.
Requirements
The FastAPI project must be managed by uv and have ruff and ty defined in the dev dependencies.
Workflow
1. Preparation
Navigate to the FastAPI backend directory.
cd backend/fastapi
2. Linting and Formatting
Run ruff to identify linting issues and potential code quality improvements.
uv run ruff check .
To automatically fix issues that can be resolved without human intervention:
uv run ruff check --fix .
3. Type Checking
Run ty to perform high-speed static type checking across the entire backend codebase.
uv run ty check .
Guidance
- Use this skill before committing major changes to the backend.
- If errors are found, report them clearly to the user and offer to fix them if possible.
ruff covers linting and formatting, while ty covers static type analysis. Both should be used for full coverage.
