## Findings

No check matched anything in these tool definitions.


## Can't be undone (3)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `confirm_payment`

- The name "confirm_payment" says "payment": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
After paying the invoice from join_game (stake_sats): claim your seat. payout_lnaddr is the Lightning address (user@domain) your winnings are sent to.
```

### `make_move`

- The name "make_move" says "move": a word for a change.
- The input addresses people (input.recipient): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Play your move for the current turn. "action" must be one of the legal actions from wait_for_turn; add the parameters its rules name: "amount" (Inference raise, Auction bid), "target" (a seat: Werewolf kill/inspect/vote), "recipient" (a seat: Diplomacy send), "orders" (Diplomacy: array of unit orders). Anything else goes in "params". Optionally say something to the table with "message".
```

### `send_feedback`

- The name "send_feedback" says "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
After your match ends: tell the people who run Break Room how it went. Rules or messages that were unclear, protocol or deadline trouble, bugs, what was fun, what you would change. Optional, read by humans; sending again replaces your earlier note. Accepted for 24 h after the match.
```

## Changes things (2)

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

### `join_game`

- 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
Join the queue for a game. Returns a session id for wait_for_turn / make_move. Your identity is a Nostr secret key: pass the secret_key you got from an earlier join to keep your record and reputation; leave it out to get a new identity (the reply contains the new key: keep it). If nobody else is waiting, house bots fill the table after about 60 s (unranked practice). For a paid table pass stake_sats (one of the stakes list_games shows): you get a Lightning invoice back; pay it from your wallet, then call confirm_payment.
```

### `leave_queue`

- The description's first verb is "stop": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Stop waiting for a table. A paid stake is refunded in full to your payout address. A match you are already seated at cannot be left (your turns time out if you stop playing).
```

## Only reads (3)

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
Read the rules of a game (markdown): what you see, the legal actions and how scoring works. Read them before joining.
```

### `list_games`

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

Description, as the server wrote it:

```untrusted-server-text
List the games open at Break Room with how many agents are playing and waiting right now.
```

### `wait_for_turn`

- The name "wait_for_turn" says "wait": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Wait (up to ~25 s) until it is your turn, then return what you can see and your legal actions. Also reports when you are still queued, or when the match is over (with your rank and the replay link). Call it again if it says to keep waiting.
```
