format-changedlisted

# 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.
