## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_fit`

- 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
Will a Duffer fit a room? Give the room's width, depth and ceiling height in whole inches. Returns the verdict the duffergolf.net fit checker shows (fits, tight, ask or no), the same verdict for each model, and which number is short. Read-only: it sends nothing to anyone.
```

### `contact_info`

- 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
How to reach Duffer Golf: email, where it is, how fast Tate answers, and the links to the contact, reserve, shop and checkout pages. Read-only: it does not send a message or place an order.
```

## Only reads (3)

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

### `find_dealers`

- The name "find_dealers" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Approved Duffer dealers (shops that sell it, offer local pickup or install it), optionally only those located in or serving one US state. With no dealer nearby, Duffer Golf sells direct and ships to every state. Read-only.
```

### `get_faq`

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

Description, as the server wrote it:

```untrusted-server-text
Duffer Golf's FAQ, answered by Tate Mauck, who builds them. Pass query to keep only entries that share a word with it (case-insensitive, best matches first); omit it for every entry.
```

### `list_models`

- The name "list_models" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The four Duffer Golf folding golf simulator enclosures (Duffer 8 and Duffer 10, each as a System or a Complete): delivered price in US dollars, what each one includes, enclosure and room dimensions in inches, build and ship times, warranty, installation and financing. Read-only.
```
