The specific AirEssentials Colorblock Tunic product page at the provided URL does not appear to exist based on current web search results; Spanx offers a similar AirEssentials Half Zip Tunic in the same fabric line for $138 (often on sale for $99). This lightweight spacer fabric tunic is praised for being ultra-soft and versatile for loungewear or travel, but consider if a half-zip style fits your needs versus solid color or competing brands.

The failure

Couldn't add it to the cart

ARC couldn't complete the test (Add to cart after a second try). HTTP 200. Screenshot: /api/shot?p=runs%2FD_JXQ6R4uW8wLP8fM1nNL%2Finstinct-step1-rwMJlt92yZCSBtTYbbOIhAZtSenvzG.png. This stopped 1 of 5 agents.

Top fix

Use a real Add to cart button, and show that the item landed in the cart.

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.
