Validate GitHub Actions workflow YAML with actionlint when editing files under `.github/workflows/`, checking CI workflow syntax, diagnosing GitHub Actions expression or schema errors, or when the user asks to lint/check Actions workflows. Prefer `bunx github-actionlint` when `bun` is available and fall back to `npx --yes github-actionlint`; use this proactively after modifying GitHub Actions workflows.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GH Actionlint ## Purpose Use `actionlint` to catch GitHub Actions workflow mistakes before CI does: YAML syntax errors, invalid workflow keys, expression mistakes, bad `needs` references, invalid triggers, and other common Actions-specific issues. Generic YAML linters are useful for indentation, but they do not understand GitHub Actions semantics. Prefer this skill whenever the file is a GitHub Actions workflow. ## When To Use Use this skill when: - The user asks to check, lint, validate, or debug GitHub Actions workflows. - You modify files under `.github/workflows/`. - CI fails with workflow parsing, expression, trigger, `needs`, matrix, or Actions schema errors. - The user asks whether a workflow step shape is valid, such as an unnamed `run:` step. ## Workflow 1. Work from the repository root when possible. 2. Identify the workflow targets: - If the user named specific files, check those files. - Otherwise, check `.github/workflows/`. 3. Choose the runner: - If `bun` is available, use `bunx github-actionlint`. - Otherwise, if `npx` is available, use `npx --yes github-actionlint`. - If neither exists, tell the user that `bun` or `npx` is needed. …

How to install
mdr add unique-divine/jiyuu/gh-actionlint@sha256:2eaf46f901b8e838The line at the top of this page pins the label git:20260612.ca1fbc5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
