What it does

Verify is an agent skill from codewhale-hq/Codewhale. Exercise the real app/API/CLI and collect observable evidence; tests alone do not count as end-to-end verification.

Its SKILL.md is about 160 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 Testing & QA. The repository describes itself as: Open-source coding agent for your terminal, built in Rust and on a journey of continuous community improvement. Issues and PRs welcome. The licence is MIT.

When your agent uses it

  • Testing & QA work in your project

Example prompts

  • “/verify”

Workflow steps

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

  1. Identify the real entrypoint (CLI binary, API, UI).
  2. Exercise it with realistic inputs.
  3. Capture outputs, exit codes, logs, or screenshots.
  4. Report evidence and remaining uncertainty.

What it can do on your machine

Read from SKILL.md and the folder at commit ad333fd. 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

Verify loads about 156 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 63 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
~156

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.

Verify

When to use

Use when the user wants proof the real surface works, not only unit tests.

Non-goals

  • Unit tests alone are not end-to-end verification.
  • Do not fake success without observable evidence.

Workflow

  1. Identify the real entrypoint (CLI binary, API, UI).
  2. Exercise it with realistic inputs.
  3. Capture outputs, exit codes, logs, or screenshots.
  4. Report evidence and remaining uncertainty.
