## Findings

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

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

annotations: {"readOnlyHint":true}; The name "checkout_link" says "checkout": a word for a change.
```


## Changes things (5)

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

### `checkout_link`

- The name "checkout_link" says "checkout": 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
The buy link for a product, as the Buy button uses. Returns the reason instead when an edition has no checkout configured. It does not buy anything.
```

### `guides`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The published guides. With no slug: the list, newest first, each with its title, description, written date and address, optionally only those whose title, description or slug contain every word of q. With a slug: that guide in full, its body as markdown. A guide that is not published is not found.
```

### `hosted_offer`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Which products this store also runs for you, hosted, and at what monthly price. Answers for one slug, or lists every hosted product when no slug is given.
```

### `product`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Everything the product page states about one product, by slug: what it does, what it runs on, its editions and prices, and the cited comparison rows.
```

### `quickstart`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The QUICKSTART file that ships inside the product, verbatim — how to install and run it. Returns nothing when that product ships none.
```

## Only reads (2)

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

### `compare`

- The name "compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
For one product slug: every cited competitor row its comparison page shows, each with the price as the vendor publishes it, the monthly figure in integer cents where there is one, the vendor page it was read on and the date it was read. Returns an empty list and the reason when the product has no cited rows.
```

### `search_catalogue`

- The name "search_catalogue" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find products by words in their name, slug, tagline or description. Returns the matches with their one-time price. Empty query returns the catalogue.
```
