## 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,"openWorldHint":false}; The description's first verb is "open": a word for a change.
```


## Deletes or cancels (1)

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

### `book_appointment`

- 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
Books an appointment. Real and immediate: the salon holds the time and the customer gets a confirmation text. It can't be cancelled or changed online, only by calling the salon. Repeating the same call returns the same booking, never a second one.
```

## Changes things (1)

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

### `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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Open start times for one service with any technician, each as an ISO start_at and a local label. Searches from now when no date is given; up to 7 days.
```

## Only reads (2)

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

### `find_salons`

- The name "find_salons" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Nail salons on Lacquer in a US city + state or ZIP code, optionally narrowed by salon name. Up to 20 per call; "total" says how many match, and "offset" pages through the rest. Salons that take online bookings ("books_online": true) come first; a salon with books_online false has no open times online and is listed with its phone number. Within that, Lacquer partner salons ("partner": true) come first; the rest rotate daily, and the order says nothing about quality.
```

### `get_salon`

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

Description, as the server wrote it:

```untrusted-server-text
A salon's address, phone, weekly hours and full service menu (service_id, price, duration).
```

## Claude Code permissions
