SKILL.md
GitHub Actions Mastery (Senior → Principal)
Operate
- Start from change safety, trust boundaries, and developer feedback loops.
- Treat GitHub Actions as production automation infrastructure, not just YAML attached to repos.
- Prefer explicit workflow boundaries, reusable patterns, and reviewable release paths.
- Optimize for safe automation, fast feedback, and low blast radius under failure.
Default Standards
- Workflow triggers must be intentional.
- Secrets, tokens, and permissions should be least-privilege.
- Reusable workflows should reduce duplication without hiding critical behavior.
- Runner strategy should reflect workload isolation and security posture.
- Supply-chain and artifact trust must be explicit.
