## What it does

This plugin integrates the Pyright language server into Claude Code. It provides static type checking and code intelligence for files with `.py` and `.pyi` extensions.

Pyright must be installed on your system separately. You can set it up using `npm install -g pyright`, `pip install pyright`, or `pipx install pyright`. Without the `pyright` package available in your environment, the language server will not work.
