Skill Benchmark

It picks a file with legacy anti-patterns (hardcoded secrets, logic in UI components, missing design tokens), refactors it using your active skills, then scores before and after using eval patterns from evals.json. The output is a compliance delta showing how much the skills improved things, plus a breakdown of where skills failed to catch issues. Honest take: it's meta tooling for tuning your skill library. If you're running multiple Claude Code skills and want data on which ones are pulling their weight versus creating noise, this gives you that signal. The iteration table helps you decide whether to refine triggers, tighten rules, or just exclude skills that don't fit your stack.
