GROK · REAL MODEL

Model x-ai/grok-4.20
This specific pink colorway of the Gymshark Adapt Animal x Whitney Shorts appears to be out of stock on the official site. The Adapt collection receives solid reviews (4.2/5) for being squat-proof, supportive, and flattering with a scrunch detail, but some note it runs small. At full price I would recommend checking Lululemon Align or Vuori Daily shorts instead for better availability, comparable quality, and often superior comfort/versatility.

The failure
Couldn't add it to the cart
“Add to bag” was clicked twice and the cart did not change. HTTP 200. Screenshot: /api/shot?p=runs%2Fz69F8SOKu3Vgv_8F3-ANW%2Fmuse-step1-8dvGmtKTcRHPYvfJnnPss9aSw2jZoO.png. This stopped 4 of 5 agents.
Top fix
Use a real Add to cart button, and show that the item landed in the cart.

The free scan puts the score on screen and emails the full report.
Share this result
Every ARC page and dataset is free to read, cite and reuse.
OpenClaw only follows labelled controls. A block at the door is one result for all five, with the HTTP evidence. The score is the ARC browser cart, the same number as a free scan. The agent-catalog check above is real and leads the buy verdict. It does not change the score. How it works.
BADGE FOR YOUR SITE
Put this on your site. It links back here. It says Agent checkout when the real catalog check returned a checkout link, and Agents chose us only when a browser cart shopper added the product to the cart.
