## Findings

No check matched anything in these tool definitions.


## Changes things (5)

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

### `futility_judge`

- 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
Record one usefulness judgment (useful / useless / partial) for a run/source/domain and return the binding verdict (CONTINUE / STOP-SOURCE / INTEGRATE-NOW / ABSTAIN). Billed as a verdict call: one-time trial, tier allowance, or x402 $0.002.
```

### `futility_receipt`

- 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
Mint the HMAC-signed abstention receipt when the run/source/domain verdict is ABSTAIN.
```

### `futility_register_run`

- The name "futility_register_run" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Register a run with its alternatives and operator-registered source identities (strings or {id, aliases}) before judging.
```

### `futility_verify_receipt`

- 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
Verify a receipt payload {receipt, signature}; total rejection with a reason on malformed/forged input.
```

### `futility_waste_report`

- 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
Waste report for a run: tokens spent after the verdict point, per source and per domain aggregate.
```

## Only reads (1)

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

### `futility_verdict`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the current verdict for a run/source/domain without recording a judgment.
```
