Format Changed Files

What it does

Runs a repository formatter through an existing external CLI instead of custom Go code.

When to use

Use this when the repository already standardizes on a formatter and you want a reusable skill wrapper around it.

How to run

Run npx prettier@3.4.2 --write . from the repository root or adapt the command to the subset of files you want to format.

Constraints

• This is a non-interactive command.
• It may download dependencies on the first run.
• It writes files in place, so review the diff after execution.
