## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `suggest_names`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Suggest first names for which personalized puzzle books are likely available. Use this when a user is unsure of a spelling, wants gift-recipient ideas, or only has part of a name. Returns popular available names, optionally filtered by a case-insensitive prefix. To confirm a specific name has matching books, follow up with `search_books`.
```

## Only reads (2)

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

### `get_book`

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

Description, as the server wrote it:

```untrusted-server-text
Re-resolve a single book's purchase URL, cover image, and ISBN from its Shopify product handle. Use this to refresh or re-reference a book across turns without re-running the full name search.
```

### `search_books`

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

Description, as the server wrote it:

```untrusted-server-text
Search for personalized puzzle books by first name. Returns matching books with direct Shopify purchase links, cover images, and ISBNs. A typical exact match returns 9 books across 3 puzzle types (mazes, name-sudokus, word searches) and 3 difficulty levels. When no exact match exists, returns similarly-named books. Use this whenever a user is shopping for a personalized gift and knows the recipient's first name.
```
