## Findings

- **warn** Annotations that disagree with the tool in `check_store_ai_readiness` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_store_ai_readiness" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The name "check_store_ai_readiness" says "store": a word for a change.
```

- **warn** Annotations that disagree with the tool in `check_page_visibility` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_page_visibility" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The description's first verb is "run": a word for a change.
```


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_page_visibility`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Runs the xfix search check on one public page: fetches it without running JavaScript, checks robots.txt for 9 crawlers, measures mobile speed and reviews text, headings and title. Returns a score out of 100, a grade, coverage, any failed gates and the 5 biggest point losses with fixes. Takes about a minute; if not finished within about 25 seconds, returns a check_id to fetch the result later.
```

### `check_store_ai_readiness`

- The name "check_store_ai_readiness" says "store": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Checks whether AI assistants and shopping agents can read an online store. Fetches the public store pages the user names, without running JavaScript. Returns the store's AI Shopping Readiness Index score if the store is in the Index, which AI crawlers its robots.txt allows, and whether one product page shows price, stock and product structured data in its HTML. Use when the user asks if AI can find, read or shop their store. Does not test checkout or log in. Use when the user gives a store or domain.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `check_ai_crawler_access`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reads a site's robots.txt the way 9 crawlers do (Googlebot, Bingbot, Applebot, OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User, PerplexityBot, Perplexity-User) and returns which may fetch the given page and the rule that blocks each one. Does not see CDN or firewall rules. Use when the user asks which bots or crawlers can access, crawl or read a site, or asks about robots.txt.
```

### `check_page_readability`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches the public page at the given URL without running JavaScript and reports whether its main text is present in the HTML. Checks one page only. Use when the user asks whether a page's content can be read without JavaScript.
```

### `check_product_page`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches one public product page without running JavaScript and reports whether the price and stock are in the HTML and which of six product structured data fields are present: price, availability, brand, identifier (gtin or sku), shipping details and aggregate rating. Use when the user gives a product page URL.
```

### `get_page_visibility_result`

- The name "get_page_visibility_result" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the result of an xfix search check started earlier, or its progress if it is still running.
```

### `lookup_index_score`

- The name "lookup_index_score" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Looks up a store domain in the xfix AI Shopping Readiness Index and returns its published score and the fields shown on the public Index page, or says the store is not in the Index. Does not fetch the store.
```
