## Findings

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

```untrusted-server-text
The server marks "remove_property_from_list" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"readOnlyHint":false,"destructiveHint":false,"openWorldHint":false}; The name "remove_property_from_list" says "remove": a word for removing or ending something.
```


## Deletes or cancels (2)

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

### `delete_property_list`

- The name "delete_property_list" says "delete": a word for removing or ending something.
- The description says "permanently delete".
- The server marks it destructive (destructiveHint: true).

```untrusted-server-text
Use this when an authenticated user explicitly asks to permanently delete one of their PropFácil favorite lists and its saved entries. Do not use it for removing a single property.
```

### `remove_property_from_list`

- The name "remove_property_from_list" says "remove": a word for removing or ending something.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.

### `publish_property`

- The name "publish_property" says "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Use this when an authenticated user explicitly asks to publish a property publicly on PropFácil. This creates a public listing and is safe to retry with the same idempotencyKey.
```

## Changes things (5)

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

### `my_listings`
