Answer yes/no on twelve authored anti-patterns — the same checklist items that keep showing up in CI/CD post-mortems — and get a weighted score, a worst-first attention list, and a sequenced fix order (caching before parallelising, since parallel jobs without a cache just multiply the waste). Free.
Unanswered questions count as "no" (the anti-pattern is not present) — answer the ones you're unsure of rather than skipping them.
The score, the attention list and the fix order are free and stay free. The Operator's Notes add what a checklist can't: why each item actually costs what it costs, and a sample pipeline shape that avoids all twelve from the start.
