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.

# .pre-commit-config.yaml — ruff (lint + format) and ty together
repos:
  - repo: https://github.com/astral-sh/ruff-pre-commit
    rev: v0.14.0
    hooks:
      - id: ruff-check
        args: [--fix]
      - id: ruff-format
  - repo: https://github.com/astral-sh/ty
    rev: 0.0.98
    hooks:
      - id: ty

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.
