What you end up with

Your agent proves the page works at phone width, with a keyboard and with a real form submission before you call it done.

What you get

  • Nine hard floor checks
  • The one truth rule
  • The browser check prompt

Who it is for

Anyone whose agent says a page is finished without opening it.

Solid chips: the agent is named in this listing's own tools list. Dashed chip: Plain Markdown, so it also pastes into other agents such as Grok Bot, Hermes, OpenClaw or Muse. We list those as compatible by format only, not as tested.

Sample prompts, free to use

Check the real page · Claude Code, Codex, Cursor
Write a Playwright script that opens [URL], screenshots it at 375, 768 and 1280 wide, logs console errors, checks every link, runs an axe scan and submits each form to [test destination].
Mark each hard floor check PASS or FAIL from the output, not from the code.

The script output decides, not the agent's opinion.

# The hard floor: nine page checks before anything goes live (free sample)

A free sample from Front-Door Review Stack by PaperChaseWebb. Works with Claude Code, Codex, Cursor or any agent that can open a browser.

Agent-built pages fail in quiet ways: a form that thanks you and sends nothing, a button that goes nowhere on a phone. Check these before you look at colors.

## The nine checks (one fail blocks publishing)

1. Text contrast meets WCAG AA (4.5 to 1 for body text).
2. Keyboard reaches everything, with a visible focus ring.
3. Nothing overflows or gets cut off at 375 pixels wide.
4. Every form submits to a real destination, proven by a test.
5. No 404s, staging links or "#" placeholders.

Worth knowing

  • Automated checks miss some problems. Tab through the page yourself once.
