What it does

Verify is an agent skill from av/mi. Run lint, typecheck, tests, or build — and fix any failures found. Use when asked "does it build", "run the tests", "check for lint errors", "find and fix lint errors", or after making code changes.

Its SKILL.md is about 1.2k 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 Linting and formatting. The repository describes itself as: self-extending sandboxed agentic harness. a loop, two tools and an llm.

When your agent uses it

  • Asked does it build
  • Check for lint errors
  • Find and fix lint errors
  • After making code changes

Example prompts

  • “does it build”
  • “run the tests”
  • “check for lint errors”
  • “/verify”

Requirements

  • Python 3

Workflow steps

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

  1. Repo instructions first. AGENTS.md, CLAUDE.md, CONTRIBUTING.md, README.md. These usually name the lint/test/build commands verbatim and…
  2. Declared build metadata. Inspect whatever the project's toolchain uses: package.json "scripts", Makefile targets, pyproject.toml / tox.ini…
  3. CI config as fallback. .github/workflows/*.yml, .gitlab-ci.yml, .circleci/config.yml, azure-pipelines.yml — these run the real check…

What it can do on your machine

Read from SKILL.md and the folder at commit 2bf50c9. 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:

    • git
    • tsc
    • eslint
    • pytest

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Verify loads about 1.2k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 619 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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 619 words (~1,160 tokens).

“Run after every non-trivial edit, not just at the end. Never invent commands — use only what the project itself declares.”
