Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No pipe-to-shell installers: failed

    Runs code fetched at install time in 5 places.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Only contacts known or declared hosts: raw.githubusercontent.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • Pinned to a commit: passed

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

The github-actions-validator skill allows AI agents to validate GitHub Actions workflows. It checks for syntax errors, semantic issues, and potential problems in your workflow files, ensuring they run correctly. This helps prevent failed CI/CD pipelines and wasted development time by identifying issues early on.

When to use it

  • Pre-commit hooks: Integrate the validator into a pre-commit hook to catch errors before code is committed.
  • CI/CD pipeline validation: Run the validator as part of your CI/CD pipeline to ensure workflows are valid before deployment.
  • Workflow troubleshooting: Use the skill to diagnose issues in existing GitHub Actions workflows that aren't behaving as expected.
  • New workflow creation: Validate new workflows during development to catch errors early and avoid integration problems.

Key capabilities

  • Syntax validation of YAML files
  • Semantic analysis of workflow steps
  • Error reporting with clear explanations

Example prompts

  • "Validate this GitHub Actions workflow: [paste workflow content]"
  • "Check the syntax of my workflow file located at /path/to/workflow.yml."
  • "Can you find any errors in this Github Action?"

Tips & gotchas

The skill requires access to the workflow file being validated. Ensure the AI agent has appropriate permissions or can access the file path correctly for accurate results.
