button-check

button-check is a skill for Claude Code from MigoXLab/webqa-agent. It costs 15 tokens per session (2,185 once invoked), scanned A, original, Apache-2.0.

A browser-testing procedure that systematically checks every clickable control and input on a page. It covers links, buttons, tabs, form fields, menus, checkboxes, radio buttons, switches, and sliders.

In plain words
What is it for?
Use it to collect a page's interactive elements, test each one with sample actions, return to the starting page between tests, and produce a step-by-step report.
Why use it?
It helps reveal broken links, inactive controls, and inputs that do not respond during a smoke or regression test.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

button-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Button Check Skill

Systematically test every interactive element on the page:

  • Clickables (button / link / tab / checkbox / radio / switch / menuitem) — click and verify
  • Inputs (textbox / searchbox / combobox / slider) — fill with sample data and verify

After each test, return to the baseline page so the next element is tested from the same starting state.

Important: Before each tool call, output a short one-line description of what you are about to do (e.g. "Filling the search box with 'hello'"). This helps generate readable step-by-step reports.

When to Use

  • Task mentions "遍历所有按钮/链接/输入", "comprehensive UI testing", or "regression testing"
  • You need to verify no broken links / dead buttons / unresponsive inputs exist
  • Smoke testing a page before a release

Skip for single-element tests — use click or fill directly instead.

Phase 1: Collect Interactive Elements

Call take_snapshot to get the accessibility tree. Group elements into two buckets by role:

Clickable bucket — driven by click:

  • button, link, tab
  • checkbox, radio, switch
  • menuitem

Input bucket — driven by fill (or type_text / press_key for keyboard-only widgets):

  • textbox, searchbox
  • combobox (treat as click-to-open if no editable affordance is visible, then fill if a textbox appears)
  • slider (fill with a numeric mid-range value)

Each element has a uid (e.g. uid=1_5), a role, and a label. Record {uid, role, label, bucket} for every element.

Cap at 50 elements total. If more exist, prioritize:

  1. Inputs (form fields) — these often gate downstream behavior
  2. button and link (core interactive)
  3. tab, menuitem (navigation)
  4. Other ARIA roles

Snapshot misses some elements? Icon-only buttons without ARIA attributes are invisible to take_snapshot. Mention in the report instead of erroring.

Phase 2: Baseline

Record the baseline state before testing:

  • Call take_screenshot with fullPage: true to capture the entire page
  • Note the current URL — this is the baseline URL you MUST return to after every test that navigates away

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
