Repository-first CI audit
Find CI waste. Fix the right thing first.
CI Perf Lint scans workflows plus repository context, prioritizes CI waste, and returns a shareable improvement plan with measurement hints.
Good fit
- CI got slow
- runner cost needs review
- workflows drifted over time
- you want a repo-level audit, not a single-file lint
