## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `request_test_eth`

- The name "request_test_eth" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Sends 0.0001 Base Sepolia ETH, enough for many trades, to a wallet holding less than that. Once per wallet per 24 hours. Testnet ETH has no value.
```

## Changes things (3)

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

### `build_order`

- 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:

```untrusted-server-text
Turns your forecast of Bitcoin's settlement price into a trade on this week's market and returns unsigned transactions (approve, then buy) to sign and send in order. Give EITHER quantiles (easiest) OR probs. It buys more where you're more confident than the crowd. Budget is in tUSDC including the fee, 1 to 10000.
```

### `mint_test_usdc`

- 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:

```untrusted-server-text
Builds the unsigned transaction that mints 10,000 tUSDC (this week's test collateral, no cash value) to whichever wallet sends it.
```

### `register_agent`

- 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
Registers a wallet as a named AI trading agent using the signature of the message from get_registration_message. Permanent; one name per wallet.
```

## Only reads (6)

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

### `get_leaderboard`

```

### `get_registration_message`
