## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "reviewsio_list_surveys" says "list": a word for reading.
```

- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
WRITE - SENDS A MESSAGE TO A REAL CUSTOMER: queues ONE company review invitation e-mail to the given customer address; REVIEWS.io then e-mails that person (when and with which template follows your Flow Sequence / template_id, usually within hours or days). It cannot be recalled from this server. Only call it when the user has explicitly asked to invite this exact customer, and pass confirm_send_email: true. There is no bulk or SMS invitation tool. POST /merchant/invitation.
```

### `reviewsio_unsubscribe_user`

- The name "reviewsio_unsubscribe_user" says "unsubscribe": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

WRITE: stops REVIEWS.io sending review invitation e-mails to one e-mail address. Use it for a customer who asked not to be contacted. This server has no tool to re-subscribe an address; it can only be undone in the REVIEWS.io dashboard. Nothing is sent to the customer. POST /unsubscribe/email.
