No check matched anything in these tool definitions.


## Changes things (3)

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

### `ask_question`

- 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
Ask one yes/no style question about the current puzzle. The AI host answers with one of four judgments: 是(Yes) / 不是(No) / 是也不是(Both) / 没有关系(Irrelevant), plus solve progress (0-100).
```

### `give_up_and_reveal`

- 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
Reveal the hidden solution and end the session. Only allowed once solve progress reaches 60.
```

### `start_session`

- The name "start_session" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start a new Turtle Soup (lateral thinking puzzle) session. Returns the surface story; the hidden solution stays on the server. Optional filters: region (CN/US/JP), difficulty, keyword.
```
