name: format description: Run code formatter on the codebase.

Format

Run code formatters to automatically fix code style.

Steps

1. Detect the project type and find the format command:

   • Nix with treefmt: nix fmt
   • TypeScript/JavaScript: prettier --write, biome format --write
   • Go: gofmt -w, goimports -w
   • Rust: cargo fmt
   • Python: black, ruff format

2. If treefmt is configured in the project, prefer nix fmt as it handles all formatters.

3. If no formatter is configured, propose adding one appropriate for the project.

4. Run the command to format the code.
