gh-fix-ci
Use when GitHub Actions PR checks are failing on a pull request and need to be diagnosed or fixed. Inspects checks / logs via gh, drafts a fix plan, and implements only after explicit approval. Trigger on red checks, failing workflow runs, pr is failing CI reports — even if the user does not name a specific check. Out of scope: external CI (e.g. Buildkite) — report only the details URL.
