## Findings

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

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

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


## Changes things (1)

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

### `practice_better_get_availability`

- The name "practice_better_get_availability" says "get": 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Open booking slots of one practitioner for one service, starting on the given day: start, end and duration of each slot. It follows the practitioner's booking settings. Needs a practitioner id and a service id. GET /consultant/availability/slots.
```

## Only reads (14)

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

### `practice_better_find_clients`

Description, as the server wrote it:
