## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "open": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "check_request_status" says "request": a word for a change.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_booking`

- The name "cancel_booking" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel a booking made earlier. customer_contact is the email or phone used for the booking.
    Only after the customer has clearly said they want to cancel; set customer_confirmed=true to say so.
    To reschedule: check_availability, confirm the new time with the customer, book_appointment, then cancel the old one.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `request_quote`

- The name "request_quote" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send a quote request to the business. Only after the customer has confirmed the details;
    set customer_confirmed=true to say so. Needs an email or phone so the business can reply.
```

## Changes things (3)

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

### `book_appointment`

- 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
Book a time returned by check_availability. Only after the customer has said yes to this exact
    business, service and time; set customer_confirmed=true to say so. Returns confirmed, pending
    (the business will confirm) or failed, with a reference.
```

### `check_availability`

- The description's first verb is "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    e.g. start="2026-10-01T00:00:00-04:00", end="2026-10-03T00:00:00-04:00". Times are offers, not holds.
```

### `check_request_status`

- The name "check_request_status" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

    request_quote or book_appointment; customer_contact is the customer's email or phone.
