Code Formatter Skill

When to use this skill

Use this skill whenever a user asks to format, lint, or clean up source code files.

Steps

1. Identify the language of the code files provided.
2. Apply the project's formatting rules (from .editorconfig or .prettierrc if present).
3. Run the formatter with --write to apply changes in-place.
4. Report which files were changed and how many lines were modified.

Important notes

• Always preserve semantic meaning — never alter logic while formatting.
• For TypeScript and JavaScript, use Prettier. For Python, use black. For Go, use gofmt.
• If no config file is present, use 2-space indentation for JS/TS, 4-space for Python.
• Do not format generated files (e.g., files in dist/, build/, or __generated__/).
