Python code quality with ruff and ty. Use when the user mentions ruff, ty, linting, formatting, type checking, or Python code style.

Python Code Quality Orchestration index for the Python quality stack. This skill routes to the focused skills that own each tool — it does not restate their commands. Reach for it when setting up or reasoning about the whole stack (lint + format + type check + tests) at once; reach for a focused skill when tuning one tool. When to Use This Skill Use this skill when... Use a focused sibling instead when... Standing up a complete quality stack for a new project Tuning only ruff lint rule selection — use ruff linting Reasoning about how the tools fit together / comparing them Configuring only ruff formatter quirks — use ruff formatting Wiring lint + type check into pre commit and CI together Configuring strict type checker rules — use ty type checking or basedpyright type checking Routing Table Concern Focused skill Lint rules, rule selection, auto fix python plugin:ruff linting Code formatting (quote style, line length) python plugin:ruff formatting Editor / pre commit / CI / Docker wiring for ruff python plugin:ruff linting → its REFERENCE.md Type checking with ty python plugin:ty type checking Type checking with basedpyright python plugin:basedpyright type checking Dead code detection python plugin:vulture dead code Test quality / coverage python plugin:python testing , python plugin:pytest advanced Modern type hint syntax and idioms python plugin:python development Adding the tools to a project python plugin:uv project management Full Stack at a Glance The one thing this index owns: the tools running together in pre commit. For each tool's flags and config, follow the routing table above. A typical CI quality gate runs the same three steps: ruff check , ruff format check , ty check . See ruff linting § CI/CD Integration and ty type checking for the runnable forms. References Ruff: <https://docs.astral.sh/ruff/ ty: <https://docs.astral.sh/ty/
