Claude Plugins

A collection of Claude Code plugins.

Quick Start

/plugin marketplace add nurikk/claude-plugins

Note: The GitHub repo is nurikk/claude-plugins, but the marketplace identifier is nurikk-plugins (used when installing plugins).

Available Plugins

Plugin	Description	Install

---

python-quality

Automatically runs Python quality checks after file changes.

What It Does

When Claude writes or edits a .py file, this plugin automatically runs:

Tool	Command	Purpose
ruff format	uvx ruff format	Auto-formats code (PEP 8 style)
ruff check	uvx ruff check --fix	Lints and auto-fixes safe issues
ty	uvx ty check	Type checks using Astral's fast type checker

Requirements

• uv - Fast Python package installer
• jq - JSON processor (pre-installed on most systems)

Install uv:

# macOS
brew install uv

# Linux/macOS (curl)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Installation

/plugin marketplace add nurikk/claude-plugins
/plugin install python-quality@nurikk-plugins

Or add directly to your ~/.claude/settings.json:

{
  "enabledPlugins": {
    "python-quality@nurikk-plugins": true
  }
}

Behavior

Auto-formatting

The plugin auto-formats Python files using ruff, which handles:

• Import sorting
• Line length enforcement
• Consistent spacing
• Quote style normalization

Auto-fixing

Safe lint fixes are applied automatically:

• Removing unused imports
• Fixing simple style issues
• Correcting obvious errors

Type Checking

Type errors are reported but don't block the operation. You'll see output like:

error[invalid-return-type]: Return type does not match returned value
 --> example.py:3:25
  |
3 | def greet(name: str) -> int:
  |                         --- Expected `int` because of return type
4 |     return "hello"
  |            ^^^^^^^ expected `int`, found `str`

Troubleshooting

Hook not running

1. Restart Claude Code after installing the plugin
2. Check hooks are registered: /hooks
3. Verify plugin is enabled in settings

Tools not found

Ensure uvx is in your PATH:

which uvx

Tools Used

• ruff - Extremely fast Python linter and formatter
• ty - Fast Python type checker from Astral

Both tools are run via uvx (uv's tool runner), so they don't need to be pre-installed.
