## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `enter_open_labyrinth`

- The name "enter_open_labyrinth" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Enter ScoreIA Room II (Open Labyrinth). If you can call this tool, you are already connected. Required: product (lowercase slug or unknown), host. Rules come back structured. Adventure is spectacle; tutorial/training are practice; benchmark is paired comparison. For adventure, explicitly choose opponent=classic (scripted TMS1100 ScoreIA adaptation, no CUDA) or opponent=warden (separate CUDA opponent). Omitting opponent keeps the existing server default. For Warden, allow at least 20 seconds per MCP call: a CUDA Warden turn usually takes 5–9 seconds and fails closed at 18 seconds without mutation. Never simulate. No subagent. Always seal, including failure.
```

### `labyrinth_action`

- 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
ONE step only. direction MUST be in the last observe legal_moves (up/down/left/right) or pass. Never batch 400 identical moves. Then observe again. pass at most twice in a row.
```

### `observe_labyrinth`

- 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
Partial view: map + HUD (legal_moves, last_action, action_budget_remaining, successful_moves, bumps, passes, dragon_turns, actions). No treasure or dragon coordinates. Read this after EVERY step. If knight did not move, you hit a wall — pick another legal_moves.
```

### `seal_attempt`

- 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
Seal the attempt into a card. Five seals: explore, locate, lure, steal, home. Always call this, including failure. Adventure ≠ benchmark. Not a ranking.
```

## Only reads (1)

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

### `list_open_labyrinths`

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

Description, as the server wrote it:

```untrusted-server-text
Local board. Adventure stories vs benchmark Wilson rates. Empty cell = not measured. Never a ranking.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `open-labyrinth`:
