## What it does

This skill does not restate tool commands. It routes. Picking lint rules sends you to `ruff-linting`; quote style and line length live in `ruff-formatting`; type checking sits in `ty-type-checking` or `basedpyright-type-checking`. Dead-code detection is `vulture-dead-code`, test quality and coverage are `python-testing` and `pytest-advanced`.

What it owns is the combined setup. The `.pre-commit-config.yaml` example wires ruff and ty in one file with three hooks: `ruff-check` with `--fix`, `ruff-format`, and `ty`. The same three steps make up a typical CI gate — `ruff check`, `ruff format --check`, `ty check`.

The skill is marked `user-invocable: false`, so there is no slash command to type. It triggers on its own when ruff, ty, linting, formatting or type checking come up in the conversation. Its allowed tools are `Bash`, `Read`, `Grep` and `Glob`. If you already know which single tool you are tuning, the index just adds a routing hop — go straight to the focused skill.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill python-code-quality -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/python-code-quality/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/python-code-quality/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill python-code-quality -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/python-code-quality/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill python-code-quality -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/python-code-quality/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install laurigates/claude-plugins python-code-quality
```

2. **Manually: put the files in place**
- File: `.github/skills/python-code-quality/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill python-code-quality -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/laurigates/claude-plugins --path python-plugin/skills/python-code-quality
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/python-code-quality/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill python-code-quality -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/laurigates/claude-plugins/tree/HEAD/python-plugin/skills/python-code-quality/SKILL.md

## When to use it
- wire lint, format and type-check into one pre-commit run
- find which skill owns a specific tool
- keep CI and pre-commit steps identical
- split ruff and ty configuration into separate tasks
- locate the skill for dead code or test coverage

## Example prompts
- set up ruff and ty in pre-commit for a new project
- which quality checks should CI run
- where do I tune ruff lint rules

# 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.

```yaml
# .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: v0.0.10
    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.
