Usage

Skills

The plugin provides skills for Astral tools.

Invoke skills with /astral:<skill>, e.g., /astral:uv.

Claude sometimes needs to be prompted to use skills. We recommend adding this instruction to your CLAUDE.md:

When working with Python, invoke the relevant /astral:<skill> for uv, ty, and ruff to ensure best practices are followed.

LSP

The plugin also provides the ty LSP. It requires uvx to be available.
