## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The input takes a statement or command to run (input.code), which can change anything it can reach.
```


## Deletes or cancels (1)

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

### `cancel_request`

- The name "cancel_request" 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
At the company chosen from find_companies (pass its `company`). Cancels the booking (only when the client asked to). Needs the token from book_appointment.
```

## Changes things (4)

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
At the company chosen from find_companies (pass its `company`). Books the visit at a free time from check_availability. Only after the client confirmed the service, the time, the address and the price. The company messages the client (WhatsApp, or e-mail when given). Returns the request number and a token for get_request_status / cancel_request. Repeating the same call (same idempotency_key or the same data) returns the same booking.
```

### `check_availability`

- 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
At the company chosen from find_companies (pass its `company`). Free start times for the service (with these answers and units — they set how long the work takes) over the next days, from tomorrow. Each time has a slot_id for book_appointment. Times are the company's local time.
```

### `company_info`

- 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
At the company chosen from find_companies (pass its `company`). The company: name, country and city, currency, languages, contacts, clients' rating, the districts it serves (main: fast arrival; secondary: next day or a call-out fee), today's date in its time zone and its booking page.
```

### `diagnose`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
At the company chosen from find_companies (pass its `company`). A preliminary hint by the air conditioner's brand and the error code on its display: the probable cause (a breakdown type) and the company's starting price for it. It is not a diagnosis. Before giving it, tell the client it is an automatic hint, that the technician confirms the cause and the final price on site, and get their agreement — then pass client_accepted_disclaimer: true (also to book_appointment with the diagnosis). Brands: daikin, mitsubishi_electric, lg, samsung, gree, midea, panasonic, carrier, haier, tcl, other.
```

## Only reads (4)

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

### `find_companies`

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

Description, as the server wrote it:

```untrusted-server-text
Service companies in the Nadveo catalog, filtered by country (ISO code, e.g. AE), city, district, service and name, best first. Each has its districts (main: fast arrival; secondary: next day or a call-out fee), "from" prices, the next free day and clients' rating.
```

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
At the company chosen from find_companies (pass its `company`). Checks the client's answers and gives the price and the duration. If an answer is missing or wrong, "problem" says which question.
```

### `get_request_status`

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

Description, as the server wrote it:

```untrusted-server-text
At the company chosen from find_companies (pass its `company`). Where a booking stands: status, time, technician (once assigned), price. Needs the token from book_appointment.
```

### `list_services`

- The name "list_services" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
At the company chosen from find_companies (pass its `company`). Every service with its starting price, how long it takes, whether it can be booked, and the questions the client answers (they set the price and the time). Questions may depend on an earlier answer (shown_if). "unknown_allowed" means "?" is a valid answer.
```
