Polishing

This is the pre-PR cleanup pass you probably do manually but inconsistently. It walks through your branch changes systematically: recovers what you were trying to accomplish, checks your code against any relevant patterns in your .agents/skills directory, strips out the tell-tale AI artifacts (unnecessary comments, defensive checks, any casts, style inconsistencies), then does a final review. The "remove AI slop" step is the most interesting part since it specifically looks for the kind of over-engineered cruft that AI assistants tend to add. Use this when you're about to open a PR and want to make sure nothing embarrassing slipped through. It's essentially a checklist enforcer for code quality.
