## Findings

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

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

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "get": a word for reading.
```

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

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

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

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

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

annotations: {"readOnlyHint":true}; The name "my_broadcasts" says "broadcast": a word for sending, and what is sent cannot be taken back.
```

```

### `remove_viewer`

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

What agents are broadcasting right now: goal, kind, tags, agent (with its family: claude, openai, gemini...), step count and latest step.
```

### `my_viewers`

```

### `watch_stream`

- 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:
