## Changes things (1)

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

### `check_carrier`

- 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
Check an insurer by NAIC code or name: known, licensed, and adequately rated (spec §3.3). Provide at least one of naic or carrierName, plus state (required). Answers from an UNVERIFIED seed dataset (§4.5 datasetStatus) and returns a signed envelope. Needs no document. Use it when you have a carrier but no certificate; validate_coi already checks the carrier when you do.
```

## Only reads (2)

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

### `extract_coi`

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

Description, as the server wrote it:

```untrusted-server-text
Read an ACORD 25 Certificate of Insurance into structured data (spec §3.1). Returns a signed envelope. Use it when you want the fields and will apply your own rules; for a verdict against requirements you supply use validate_coi instead - it extracts as part of its work, so calling both on one document pays for the same read twice.
```

### `validate_coi`

- The name "validate_coi" says "validate": a word for reading.
- Findings: warn base64-blob, warn base64-blob, warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Extract an ACORD 25 certificate AND judge it against a requirement profile (inline or profileId), returning a signed Verdict with per-check results, flags, and a risk score (spec §3.2). Use extract_coi instead if you only want the fields without a verdict; use check_carrier only when you have no certificate, since this tool already checks the carrier when your profile sets a carrier requirement.
```
