## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `carrier_record`

- 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
Qualify a USDOT number and an as-of date: whether this archive can answer for them, what each source holds for the period, and what a purchased record could establish. It returns no row of the record. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.
```

### `carrier_record_by_docket`

- 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
Qualify a docket number and an as-of date: whether this archive can answer for them, what each source holds for the period, and what a purchased record could establish. It returns no row of the record. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.
```

### `verify`

- 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 Substradium fingerprint. The answer names neither the carrier nor the customer. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.
```

## Only reads (2)

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

### `coverage`

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

Description, as the server wrote it:

```untrusted-server-text
Return the read surface's coverage, its limits and how the record is bought.
```

### `specimen`

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

Description, as the server wrote it:

```untrusted-server-text
Return one published specimen. A specimen is a sample with the carrier withheld, not an issued record.
```
