## 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.

### `payment_preflight`

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

Description, as the server wrote it:

```untrusted-server-text
Paid $0.02 technical Base payment preflight using independent RPCs. Supports x402 v2 or a legacy HTTP Bearer token. Not financial advice.
```

## Changes things (2)

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

### `bounty_reality_check`

- 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
Free fresh GitHub bounty reality check. No registration or email.
```

### `repo_contribution_readiness`

- 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
Paid $0.10 repository contribution readiness from current public GitHub data. Supports x402 v2 or a legacy HTTP Bearer token.
```
