What does pyright-lsp do?
pyright-lsp is a Claude Code plugin that connects Claude to Pyright, Microsoft's Python language server, for .py and .pyi files. With it Claude gets static type checking and code intelligence while it reads and edits Python. The plugin only registers the server, started as pyright-langserver --stdio, and adds no skills, commands or hooks. You install Pyright yourself beforehand, with npm install -g pyright, pip install pyright, or pipx install pyright, which the readme suggests for command line tools.
