github-actions-debugger

authentic

Specialized skill for diagnosing, analyzing, and fixing failing GitHub Actions workflows by parsing run logs and pipeline definitions.

When to use

• Use when a GitHub Actions workflow fails unexpectedly and the error log is long, obscure, or misleading.
• Use when debugging dependency mismatch errors, missing secrets, caching issues, or runner environment problems in CI.
• Use to optimize slow pipelines by identifying bottlenecks in workflow steps.
• Use to update and modernize deprecated actions or workflow syntax.

When not to use

• The skill cannot securely read repository secrets. It can only infer missing or malformed secrets if the log complains about undefined environment variables or authentication failures.
• It cannot execute the GitHub action itself to test the fix; validation requires pushing the proposed fix to the repository and triggering a workflow run.
• Network-related transient failures (e.g., a package registry being down temporarily) might be incorrectly diagnosed as structural workflow issues if not carefully analyzed.
