Gemini CLIAbout this skill
Reviews and optimizes GitHub Actions workflows for performance (cache layering, matrix sharding with Vitest 2.x+/Playwright blob+merge), quality (gate separation, observability via STEPSUMMARY), security (SHA pinning of third-party actions, OIDC instead of long-lived secrets, pullrequesttarget hardening, persist-credentials hardening), and avoids documented anti-patterns (parallel cache corruption, eval gates without baseline, duplicate CI runs on same SHA). Use when editing any file under .github/workflows/, when adding or removing CI jobs, when triaging slow CI, when reviewing third-party action updates, or when discussing supply chain security of GitHub Actions (SHA pinning, OIDC, third-party action updates).
