What this prompt does

Proves the browser has really forgotten you before it starts
Opens your site at phone size as a brand-new visitor
Tries to join your list and tries to buy, stopping before payment
Reports the five biggest problems, worst first, with the smallest fix

Why it works

Opens your site on a phone as someone who has never seen it, tries to sign up and buy, and reports what got in the way. You know where every button is, which is exactly why you can't judge your own site.

Tested on a live business site, all the way through the buy step, stopping at the payment screen.

Step zero is the part nobody else does, and it exists because the obvious version of this prompt is quietly broken. The setting that is supposed to make the browser forget you does not reliably do it. On a live run the browser still carried a tracking cookie from an earlier visit, with a counter reading session number two — the "first-time visitor" had been there that morning. Every finding from a walk like that reads as clean and proves nothing.

So it now checks three things before it walks and refuses to start if any come back dirty. On the run that caught this, only one of the three spotted it; the other two looked fine. The obvious one-check version would have said "all fresh" and been wrong.

Setup

Fill in the two brackets
Swap [YOUR WEBSITE] and [YOUR EMAIL] for your own.
Paste it into Claude Code and let it set itself up
It installs Playwright if it needs to and opens the browser in isolated mode.
Let it run its three freshness checks before it walks
It looks for stored data, a tracking cookie, and a saved cookie-banner decision. If any of the three comes back non-empty it stops and tells you the browser is not fresh. Don't argue with it — restart and go again. A contaminated walk finishes, reads as clean, and misses everything a real first-time visitor hits.
Read the report top to bottom before you reply
Up to five problems, worst first, each with the smallest fix. Your instinct will be to explain why each one isn't really a problem. That instinct is the reason you needed it.
Fix the first finding, then run it again
One at a time beats a list you never start.
