What it does

Verify Atlas is an agent skill from poteto/verification-skill-example. Drive the Atlas workspace UI in a running Harbor Labs desktop build via CDP. Use for screenshots, clicks, sending messages, accessibility-tree inspection, JS evaluation, or visual-state checks.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 37 other files, including reference files (for example `references/features/README.md`, `references/features/command-palette.md` and `references/features/extensions-catalog.md`).

It sits in Frontend & Design, covering Accessibility. It works with Git. The repository describes itself as: Example: project-local verification skill + large-app feature map (fictional Atlas / Harbor Labs).

When your agent uses it

  • Sending messages
  • Accessibility-tree inspection
  • Visual-state checks

Example prompts

  • “/verify-atlas”

What it can do on your machine

Read from SKILL.md and the folder at commit d5abe70. 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:

    • node

    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 Atlas loads about 1.4k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 491 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~14k

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 491 words (~1,366 tokens).

“Drive a running Atlas desktop build over CDP: inspect the DOM, take screenshots, click, type, read the accessibility tree, evaluate JS, and manage checkout-isolated parallel instances.”
