## Scores
| Measure | Score |
| --- | --- |
| Humans | 68/100 |
| Agents | 52/100 |
| Composite | 60/100 |

The human score is the mean of the four human dimensions, the agent score the mean of the six agent dimensions, and the Door Gap the difference between them.
## What the machine actually did
The agent got through 9 of 17 requests, but could not read the site's own guide for language models. It came up empty on 7 other checks too.
- ok      reach the site at all
- ok      find out whether machines are welcome
- ok      ask whether the door opens for requests carrying the AI crawlers' names
- missing read the site's own guide for language models
- ok      find out what pages exist
- missing find a contact route for machines
- missing find a published agent interface
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- ok      read the homepage as data rather than as a page
- missing find a machine readable API spec
- missing read the developer documentation
- ok      read the prices without running JavaScript
- ok      read the product catalogue as data
- ok      read a product page as data
- missing read the returns and shipping terms
- ok      walk the way a visitor would, to a signup form or a product
## Top issues
1. **No returns or shipping policy page reads as text at the usual paths, so an assistant has no terms to quote beside the price.** (machine_fetchable_trust)
2. **No shipping policy is published in structured data or as a readable page, leaving agents unable to quote delivery terms.** (commercial_rails)
3. **No API surface or developer documentation exists, forcing agents to scrape the storefront instead of querying a catalog endpoint.** (programmatic_onboarding)

## Files generated from this scan
- **Product markup skeleton** at `/product/160/stack-and-sculpt-peptides-plus-creatine`, 2 hours, developer. Verify: The next scan reads price, currency and availability in the Product markup of at least one product page.
- **Put Yotpo reviews in the page** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds review text in the server HTML of a product page.
- **robots.txt rules for AI crawlers** at `/robots.txt`, 10 minutes, no developer needed. Verify: The next scan reads robots.txt and finds every search and agent crawler allowed, none of them kept off product or pricing paths.
- **Returns and refunds page** at `/returns`, 30 minutes, no developer needed. Verify: The next scan reads the returns policy page as text without JavaScript and finds it linked from a product page.
- **Shipping and delivery page** at `/shipping`, 30 minutes, no developer needed. Verify: The next scan reads the shipping policy page as text without JavaScript and finds it linked from a product page.
- **Agent checkout: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds a UCP manifest, a storefront MCP endpoint or another discovery file answering, and the checkout check passes.
- **security.txt** at `/.well-known/security.txt`, 10 minutes, no developer needed. Verify: The next scan fetches /.well-known/security.txt as text and the security.txt check passes.
- **Machine interfaces: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds the interface you published answering at its well-known path, and that check passes.
- **llms.txt** at `/llms.txt`, 15 minutes, no developer needed. Verify: The next scan fetches /llms.txt as text and the llms.txt check passes.

## The agent door
- **machine_discoverability** 100/100. No AI crawler is blocked by robots.txt, a real browser is served the page normally, and the sitemap lists 213 URLs including product pages. Product structured data carries price, currency, availability, GTIN, brand and rating.
- **programmatic_onboarding** 10/100. No API documentation, OpenAPI spec, or developer surface exists. No MCP manifest at standard paths. An agent cannot programmatically query the catalog or place an order; it must browse the storefront like a human.
- **pricing_legibility** 90/100. 9 prices appear in the homepage HTML and 31 prices across 3 product pages without JavaScript. Product structured data publishes price in USD and currency code. The visible price ($50) matches the structured price (49.99).
- **agent_aware_instrumentation** 8/100. No MCP manifest exists at the 3 standard paths checked. No UCP manifest or commerce platform detection. An agent has no published protocol to interact with the store beyond reading HTML.
- **machine_fetchable_trust** 40/100. No security.txt or llms.txt published. The homepage answers automated requests and carries Organization schema with contact details. Trust signals are minimal; an agent cannot verify the merchant's security posture or policies from.
- **commercial_rails** 61/100. Product markup carries price, currency, GTIN, brand, aggregate rating (4.87 stars over 82 reviews) and a 30-day return policy in structured data. The sitemap lists products.
## The human door
- **steps_to_first_value** 95/100. A product with price ($50) and an add-to-cart control is reachable in 2 steps from the homepage. The product page renders fully without JavaScript. An agent or human can reach a buyable item almost immediately.
- **required_fields** 65/100. The product page carries no account requirement before adding to cart. However, the entry_path data shows guestCheckout is false, indicating checkout itself requires an account.
- **verification_walls** 75/100. No sign-in requirement appears on the product page itself. An agent can read product details, price and reviews without logging in. The wall appears only at checkout, not during discovery or product evaluation.
- **error_recovery** 35/100. 7 inputs are present on the product page, but 0 carry validation rules, descriptions or live error regions. An agent submitting invalid data receives no inline guidance on what went wrong or how to correct it.
