Github Actions Docs

GitHub Actions questions are easy to answer from stale memory. Use this skill to ground answers in official GitHub documentation and return the closest authoritative page instead of generic CI/CD advice.

When to Use

Use this skill when the request is about:

• GitHub Actions concepts, terminology, or product boundaries
• Workflow YAML, triggers, jobs, matrices, concurrency, variables, contexts, or expressions
• GitHub-hosted runners, larger runners, self-hosted runners, or Actions Runner Controller
• Artifacts, caches, reusable workflows, workflow templates, or custom actions
• Secrets, GITHUB_TOKEN, OpenID Connect, artifact attestations, or secure workflow patterns
• Environments, deployment protection rules, deployment history, or deployment examples
• Migrating from Jenkins, CircleCI, GitLab CI/CD, Travis CI, Azure Pipelines, or other CI systems
• Troubleshooting workflow behavior when the user needs documentation, syntax guidance, or official references

Do not use this skill for:

• A specific failing PR check, missing workflow log, or CI failure triage. Use gh-fix-ci.
• General GitHub pull request, branch, or repository operations. Use github.
• CodeQL-specific configuration or code scanning guidance. Use codeql.
• Dependabot configuration, grouping, or dependency update strategy. Use dependabot.

Workflow

1. Classify the request

Decide which bucket the question belongs to before searching:

• Getting started or tutorials
• Workflow authoring and syntax
• Runners and execution environment
• Security and supply chain
• Deployments and environments
• Custom actions and publishing
• Monitoring, logs, and troubleshooting
• Migration

If you need a quick starting point, load references/topic-map.md and jump to the closest section.

2. Search official GitHub docs first
