SKILL.md
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.
