What it does

Diagnose CI Failures is an agent skill from Terry-Mao/AICodingFlow. Diagnose a PR, branch, run, or GitHub Actions URL from CI evidence and produce a fix plan without changing code.

Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Failing and flaky tests and CI/CD. It works with GitHub Actions. The repository describes itself as: Setup a AI Coding Flow. The licence is MIT.

When your agent uses it

  • Tasks that involve Failing and flaky tests
  • Tasks that involve CI/CD

Example prompts

  • “/diagnose-ci-failures”

What it can do on your machine

Read from SKILL.md and the folder at commit 7703e16. 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

    Shell commands in SKILL.md call:

    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    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

Diagnose CI Failures loads about 447 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 207 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~447

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.

diagnose-ci-failures

Use this when the user asks to inspect failing CI. This skill is diagnosis-only: it produces a reviewable plan and does not edit, commit, push, or create PRs.

Find and inspect the target

Use the user's run URL, run ID, or branch when provided. Otherwise inspect the current branch's PR and failed checks, then fall back to recent failed runs for that branch. If no failing target exists, report that and stop.

bash
gh run view <run-id> --verbose
gh run list --branch <branch> --status failure --limit 5
gh pr view --json number,title,url,state,statusCheckRollup

For the selected PR/run, identify completed, pending, passed, and failed checks. If checks are still running, report the partial state instead of guessing. Pull failed-step logs first:

bash
gh run view <run-id> --log-failed

Inspect a specific job or download artifacts only when the failed-step output is insufficient. Extract observed paths, line numbers, error messages, failing tests, stack traces, and environment/permission failures.

Produce the plan

Group evidence into build/compile, test, lint/format, and environment/setup failures. Do not assume a language, tool, or root cause before repository files or logs establish it. Write a plan containing:

  • problem statement and affected checks;
  • current evidence and locations;
  • likely root cause grounded in the logs;
  • specific proposed changes;
  • validation steps for the follow-up implementation.

Prefer CI evidence over local guesses. Treat multiple unrelated failures as separate categories and recommend resolving them one category at a time.
