## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `submit_listing`

- The name "submit_listing" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submit the user's own product to the marketplace. Requires the creator's API key (duk_..., from the Creator dashboard -> API keys; never guess one). Free. Every submission is screened and waits for human owner approval; nothing is published automatically. Only submit real products the user owns, with accurate claims.
```

## Only reads (3)

### `get_listing`

```

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

```untrusted-server-text

```

### `search_listings`

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

Description, as the server wrote it:

```untrusted-server-text
