What it does

Fix CI is an agent skill from ccusage/ccusage. Diagnoses and fixes failing GitHub Actions checks with gh. Use when CI fails on a pull request and needs logs, focused fixes, and validation.

Its SKILL.md is about 490 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 Development, covering Failing and flaky tests, Pull requests and CI/CD. It works with GitHub Actions.

When your agent uses it

  • CI fails on a pull request and needs logs
  • Tasks that involve Failing and flaky tests
  • Tasks that involve Pull requests

Example prompts

  • “Use the fix-ci skill to diagnose and fixes failing GitHub Actions checks with gh. An agent skill from ccusage/ccusage”
  • “/fix-ci”

Workflow steps

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

  1. Read the check state with gh pr checks, then pull the failing job logs with
  2. Reproduce locally. CI runs almost everything through Nix, so the failing step maps onto a
  3. Fix the smallest cause that explains the failed check, using the skill for the area being
  4. Commit with the commit skill; a manifest change and its lockfile update belong in the
  5. Push, then use create-pr to comment or request another review pass when appropriate.

What it can do on your machine

Read from SKILL.md and the folder at commit d2fd844. 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:

    • just
    • gh
    • nix
    • cargo

    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

Fix CI loads about 487 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 198 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
~487

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 198 words (~487 tokens).

“gh run view --log-failed. Logs fetched through gh are reproducible; browser-only inspection is not. Pending checks can usually wait unless the failure is already clear.”
