What it does

Zuul is an agent skill from vexxhost/atmosphere. Troubleshoot failing Zuul CI jobs for this project. Use this when asked to debug, investigate, or fix Zuul job failures.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `logs.md` and `scan-manifest.py`).

It sits in DevOps & Cloud. The repository describes itself as: Simple & easy private cloud platform featuring VMs, Kubernetes & bare-metal.

When your agent uses it

  • DevOps & Cloud work in your project

Example prompts

  • “/zuul”

Requirements

  • Python 3

Workflow steps

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

  1. Start with the buildset API to identify which job(s) failed.
  2. Grep job-output.txt for FAILED (excluding RETRYING) and
  3. If the failure is in a verify/test stage (for example tempest), check
  4. Use the scan-manifest script to discover available artifacts, then
  5. Cross-reference Ansible task output (ok vs changed vs failed)

What it can do on your machine

Read from SKILL.md and the folder at commit af363d1. 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

    Ships script files (Python), which the agent can run.

    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

Zuul loads about 1.3k tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 743 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 743 words (~1,298 tokens).

“Get the list of checks for the pull request. Identify the Zuul check by looking for a check whose URL points to a Zuul instance (typically containing /buildset/ in the path). Note the check name, status, and buildset URL for…”
