At a glance

Verify cart quantities and a fresh checkout outcome without inventing display formats or reusing an earlier receipt.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Checkout Verification is an agent skill from BetterWright/betterwright. Verify cart quantities and a fresh checkout outcome without inventing display formats or reusing an earlier receipt.

Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A persistent, policy-guarded Playwright browser for AI agents — network policy, encrypted credential vault, proof screenshots, and CAPTCHA solving. The licence is MIT.

Example prompts

  • “/checkout-verification”

What it can do on your machine

Read from SKILL.md and the folder at commit ec55a32. 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

Checkout Verification loads about 358 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 162 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~358

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.

shopping cart, in the cart, checkout, place an order, submit exactly once

Grounded checkout verification

Inspection doesn't authorize changes. Guardrail prohibitions or missing required approval are valid stops; completion feedback grants no new permission.

Read the scoped cart after editing, excluding catalogue text:

  • Notebook, Notebook, Pen means two notebooks and one pen, without an x2 label.
  • Read quantities with their labels/column headers; the number of rows is not the quantity.
  • Match duplicate names by container, variant, and price; verify form values separately.

Submit only when observed items, quantities, and details match. Unknown format? Return scoped evidence before asserting or submitting.

Record the previous result, submit once, and wait for a fresh outcome. Processing, changed text alone, and an unchanged earlier receipt aren't acceptance. Order 42 confirmed is positive; rejection overrides an old success.

Extract IDs from this submission's fresh positive confirmation, not the whole page. Rejected/unverified outcomes have no new ID. Never resubmit for evidence. Scroll the fresh outcome into view, capture proof in the same call, and report the decision and quantities concisely.
