github-actions-docs

Ask your GitHub Actions syntax question and the Skill searches docs.github.com for the workflow syntax, events, contexts, or expressions reference pages. It reads the most relevant page and answers with exact documentation links rather than relying on memory.

Coverage includes workflow YAML, triggers, jobs, matrices, runners, reusable workflows, artifacts, caching, secrets, GITHUB_TOKEN, OIDC, artifact attestations, environments, deployments, custom actions, Actions Runner Controller, and migration from Jenkins, CircleCI, GitLab CI/CD, Travis CI, or Azure Pipelines.

Yes, migration questions are routed to the official migration hub page first, then to the platform-specific guide such as migrating from Jenkins, CircleCI, or GitLab CI/CD. Answers cite the exact migration documentation pages.

Do not use it for triaging a specific failing PR check or missing workflow log, which belongs to gh-fix-ci. CodeQL configuration goes to codeql, Dependabot questions to dependabot, and general pull request operations to github.

YAML examples are provided only when you ask for them or when the documentation page makes an example necessary. The default answer shape is a direct answer, relevant docs links, and an explicit callout for any inference.
