## 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.

### `verify_agent_payment_intent`

- The input carries an amount (input.payment.amount) and a currency, so it moves money.
- The input addresses people (input.payment.recipient): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Paid transaction preflight. Checks mandate, amount, destination, merchant, expiry and replay risk before an autonomous payment executes. Costs $0.05 USDC on Base.
```

## Changes things (2)

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

### `foxify_preflight_info`

- 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 metadata for FOXIFY machine-payable authority preflight tools.
```

### `verify_agent_action_intent`

- 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 exact-action authority preflight for consequential agent tool calls. Binds subject, tool, operation, target, canonical parameters, authority lifetime, retries and postcondition requirements. Costs $0.25 USDC on Base.
```
