## Findings

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

```untrusted-server-text
The server marks "get_hotel_details" as not read-only (readOnlyHint: false), and its words say it reads.

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

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

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

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

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "pay_order" says "pay": a word that usually means money moves, which cannot be taken back.
```


## Deletes or cancels (1)

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

### `purchase_hotel`

- The name "purchase_hotel" says "purchase": a word that usually means money moves, which cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Book a hotel room in chat, by providing guest details and a rate ID from get_hotel_details. Use start_checkout instead, which opens a booking form; call this only when the user says they cannot see or use that form. Creates a guest profile, adds the room to a cart, and initiates checkout. Ask the user how they want to pay before calling, and pass it as payment_service: 'x402' (USDC on Base, paid by an x402 payments tool you have) or 'coingate' (a checkout page the user pays in their browser, any crypto). If you have no x402 payments tool, use coingate. Returns a payment_url and the cart_url where the order can also be paid in a browser. The booking is confirmed once payment settles; poll get_order_details to check status.
```

## Can't be undone (1)

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

### `pay_order`

- The name "pay_order" says "pay": a word that usually means money moves, which cannot be taken back.
- 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 CoinGate's checkout page for an unpaid CoinGate booking, so the user can pay in their browser. Pass the cart_id from purchase_hotel or the booking form. Where the client supports it, this asks the client to open the page for the user (URL elicitation); otherwise, and once the page has been offered, it returns the order with its payment link. Not for x402 bookings, which your payments tool pays.
```

## Changes things (2)

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

### `get_hotel_details`

- The name "get_hotel_details" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Get rooms and rates for a hotel. Pass the hotel id from search_hotels results. Returns rate IDs needed for purchase_hotel. Each rate states its refundability and, when refundable, the cancellation deadline — quote these rather than inferring refund terms. When prices_changed is true, the price search_hotels quoted for this hotel is no longer the one on offer — tell the user prices changed rather than presenting these rates as the same quote. When the user picks a rate, call start_checkout with its id next -- it opens the booking form, so do not ask for guest details in chat.
```

### `start_checkout`

- The name "start_checkout" says "start": 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 the booking form for a rate the user picked from get_hotel_details. Shows the stay and the price, and lets the user enter the guest details and choose how to pay. On the first call, pass the user's own details you already know -- from this conversation or your memory of them -- so the form opens prefilled, and only those: never invent or guess any; the form asks for the rest and the user reviews every field before booking. If the user has not stated a title, pass title_suggestion instead: your best guess from their first name, which the form labels as a suggestion. If the user submits the form, it books the room itself (purchase_hotel) and tells you the booking reference: do not call purchase_hotel again for it. Call this again with more details to refill the form.
```

## Only reads (2)

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

### `get_order_details`

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

Description, as the server wrote it:

```untrusted-server-text
Get the current state of an order. Returns payment status, booking state, and item details. Poll until ready is true to confirm the booking is complete.
```

### `search_hotels`

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

Description, as the server wrote it:

```untrusted-server-text
Search for available hotels by destination and dates. Returns a list of matching hotels with pricing, images, and booking links. Occupancy is fixed at 2 adults in one room and cannot be set. If the user asked for a different party size, tell them these prices are for 2 adults rather than presenting them as a quote for their group. Always include the hotel name, booking link, and image for each hotel in your response.
```
