## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "open_daily" says "open": a word for a change.
```


## Changes things (1)

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

### `open_daily`

- The name "open_daily" says "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 a playable daily, or the thirteen-puzzle hub when game is omitted or hub. Pass a game id to open that board; game defaults to hub. Progress stays in the widget and does not sync to the website. Do not reveal solutions. Use list_dailies to browse and get_rules to explain a game instead of opening it.
```

## Only reads (2)

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

### `get_rules`

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

Description, as the server wrote it:

```untrusted-server-text
Explain one game's rules and controls as titled steps, never a puzzle answer. Required game is a game id, not a board. Use this to teach a game. Use list_dailies to browse today's puzzles and open_daily to play.
```

### `list_dailies`

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

Description, as the server wrote it:

```untrusted-server-text
List today's thirteen puzzles, their blurbs, and exact daily ids. No answers. Use open_daily to play one or the hub, and get_rules to explain a game without opening it.
```
