## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "find_open_slots" says "find": a word for reading.
```


## Deletes or cancels (5)

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

### `book_session`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Book a client into a service at a start time, the same way the dashboard books. Returns a preview first and only acts when confirm=true. A past start is saved as completed with no email. A future start emails the usual confirmation. No money moves through the assistant. Any pay link is only a request the client pays on Appty.
```

### `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 one booking under the provider's cancellation policy and email the client. Returns a preview first and only acts when confirm=true. No money moves through the assistant. Any refund or fee is applied by Appty, the same as the dashboard. The client pays anything still due on Appty.
```

### `reschedule_booking`

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

Description, as the server wrote it:

```untrusted-server-text
Move a booking to an open slot. The client is not emailed. Returns a preview first and only acts when confirm=true. No money moves through the assistant.
```

### `send_invoice`

- The name "send_invoice" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Create one invoice per currency for a client's sessions (by id or by calendar month) and email it. Returns a preview first and only acts when confirm=true. No money moves through the assistant. The invoice only sends a request the client pays on Appty.
```

### `send_pay_link`

- The name "send_pay_link" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Email a pay link for one booking, or for a client's unpaid sessions and invoices. Returns a preview first and only acts when confirm=true. No money moves through the assistant. This only sends a request the client pays on Appty. Group spots, packages, and fees are not emailed.
```

## Changes things (2)

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

### `find_open_slots`

- The name "find_open_slots" says "find": a word for reading.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Open start times for a public service, using the same slot rules as the booking page. from_date and to_date are YYYY-MM-DD and at most 31 days apart. Each start is ISO 8601 with the provider's offset, plus a provider-local label.
```

### `who_owes`

- 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
Unpaid balances for this provider, grouped by client and currency. Same figures as the dashboard who-owes page.
```

## Only reads (4)

### `get_booking_link`

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

Description, as the server wrote it:

```

### `get_provider`

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

```

### `list_bookings`
