## How we measure it

We look for an add-to-cart signal in the product page’s initial HTML: a cart form, cart attributes or “Add to cart” text. Present passes, absent fails.

### What the result page says

These are the sentences in the test result; “…” is replaced by what we found on your site.

- Passed An add-to-cart button or form is in the initial HTML.
- Passed With a real browser we found the button and added the product to the cart.
- Failed No add-to-cart button was found in the initial HTML; it may be drawn entirely by JavaScript.

## How to fix it

**Target:** Add to cart is a real <button> or form in the initial HTML.

### Example code

`<form action="/cart/add" method="post">
<input type="hidden" name="id" value="SKU-001">
<button type="submit">Add to cart</button>
</form>`
Example values (example.com, product name, price) are placeholders; replace them with your own.

### How to verify it yourself

View the source and look for the “Add to cart” button or a /cart form.

### Fix it with an AI coding agent

Paste this into Claude Code, Cursor or another coding agent working on your store’s code. Review the change before you deploy it.

`You are working on my online store. Specoria’s agent readiness test checks the item below. Fix it so AI shopping agents can read the store and act on it.

## 1. Add-to-cart button in the initial HTML (add_to_cart)
Target: Add to cart is a real <button> or form in the initial HTML.
Example fix (adapt it to this codebase and platform; example values are placeholders):
```
<form action="/cart/add" method="post">
<input type="hidden" name="id" value="SKU-001">
<button type="submit">Add to cart</button>
</form>
```

## Rules
- First look through the codebase and tell me which files or templates you will change, before editing anything.
- Change only what these checks need, and keep the visible page and the structured data saying the same thing.
- Never invent prices, stock, shipping or return terms, reviews or product identifiers (GTIN): take them from the store’s real data or ask me.
- Don’t block or slow down real visitors and don’t add tracking.
- After deploying, run the free test again at https://specoria.com/ to verify the fix.`
