What it does

Verifier Setup is an agent skill from AI-Builder-Club/skills. Set a repo up to prove engineering-task work actually works before it ships. Investigates the repo, ensures a one-command dev stack (dev-local) exists, asks whether verification runs locally or in a sandbox (crabbox), confirms/installs the driver (the playwright-cli skill for web by default). Outputs three artifacts: a committed /verify skill (per-task verification SOP — spawn a verifier sub-agent → drive the app → screenshot/video proof → open a PR with the proof embedded), the /dev-local skill + script, and the…

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including assets (for example `assets/verify.template.md`).

It sits in Testing & QA, covering Operations and SOPs, Pull requests and Subagents. It works with Playwright. The repository describes itself as: Codebase harness + loop engineer.

When your agent uses it

  • Someone says set up verification
  • Make this repo verifiable
  • Scaffold a verify skill
  • Set up the verifier

Example prompts

  • “set up verification”
  • “make this repo verifiable”
  • “scaffold a verify skill”
  • “/verifier-setup”

Requirements

  • Node.js
  • Docker

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Inventory what already exists (check before you add ANYTHING)
  2. Investigate the repo (don't guess)
  3. Ensure the prerequisites exist (reuse-or-provide, per the Step 0 inventory)
  4. Ask the user: local or sandbox?
  5. Confirm the driver
  6. Generate .claude/skills/verify/SKILL.md
  7. Hand off

What it can do on your machine

Read from SKILL.md and the folder at commit 917780c. 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

Verifier Setup loads about 2.1k tokens when it runs. Until then it costs about 172 tokens; SKILL.md has 1,059 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~172
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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 1,059 words (~2,082 tokens).

“Goal: leave the repo able to prove an engineering task works before it ships — run once, and it wires up everything the per-task /verify loop needs.”
