Frequently asked questions
Does this replicate GitHub's workflow validator?
No. It checks basic structure and does not validate all expressions, event rules, actions, permissions, or runner behavior.
Does it run the workflow?
No. Workflow contents are parsed locally and never executed.
Are remote actions inspected?
No. Action references are not fetched or checked for versions.
