Can Shopper C buy from your store?

Shopper C added the product to the cart at 54 of 83 published Index stores where this shopper has a result. The most common stop is Couldn't add it to the cart (15 stores).

What Grok tells shoppers is a real model call via API, checked against the store's pages, not the consumer Grok app. Whether agents reach checkout is two lanes: a real HTTP check of the store's agent catalog, and five ARC browser cart tests. Those attempts are not a live Muse, Instinct, Grok Bot, OpenAI dots, or OpenClaw session. The score is the browser lane. The catalog check does not change it. Not affiliated with or endorsed by Meta, Spear Street Technology, SpaceXAI, OpenAI, or the OpenClaw Foundation.

How this shopper is set up

Shopper C takes a visible size and clicks an obvious Add to bag. OpenClaw only follows labelled controls. A block at the door stops all five.

The counts below are this ARC browser cart pass, not a live Grok Bot session and not the agent-catalog check.

What Grok gets wrong

What a real Grok model call via API told a shopper, checked against the store's own pages. Not the consumer Grok app. A row appears only when that call disagreed with the page.

All stored mismatches

Where the browser cart pass stops

  • Couldn't add it to the cart · 15 stores

    Use a real Add to cart button that works without a custom script, and show that it worked (a cart count, a drawer, or an “added to cart” line) so a personal agent can tell the click landed.

  • Blocked at the size picker · 5 stores

    Expose variants as labeled, accessible controls (radio or select with aria + stable ids and machine-readable values). Pre-select a sensible default, or let add-to-cart surface the required choice clearly instead of silently failing.

  • Stopped by a human-check · 3 stores

    Don't gate browsing or add-to-cart behind CAPTCHA. Reserve challenges for genuinely high-risk actions, and let verified agents pass.

  • Store blocks automated agents at the door · 2 stores

    Let personal agents fetch the product page. Keep bot checks on checkout, not the catalog.
