Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  2. Use the summarize_job_log_failures tool to get an AI summary of the logs for failed jobs, to understand what went wrong without filling…
  3. If you still need more information, use the get_job_logs or get_workflow_run_logs tool to get the full, detailed failure logs
  4. Try to reproduce the failure yourself in your own environment.
  5. Fix the failing build. If you were able to reproduce the failure yourself, make sure it is fixed before committing your changes.ng to use…

What it can do on your machine

Read from SKILL.md and the folder at commit 49aa91f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

GitHub Actions Failure Debugging loads about 312 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 141 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~312

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

To debug failing GitHub Actions workflows in a pull request, follow this process, using tools provided from the GitHub MCP Server:

  1. Use the list_workflow_runs tool to look up recent workflow runs for the pull request and their status
  2. Use the summarize_job_log_failures tool to get an AI summary of the logs for failed jobs, to understand what went wrong without filling your context windows with thousands of lines of logs
  3. If you still need more information, use the get_job_logs or get_workflow_run_logs tool to get the full, detailed failure logs
  4. Try to reproduce the failure yourself in your own environment.
  5. Fix the failing build. If you were able to reproduce the failure yourself, make sure it is fixed before committing your changes.ng to use environment variable expansion instead of hardcoded API key values.
