### `check_recalls`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Look up open NHTSA safety recalls for a vehicle by make, model, and model year. Returns every campaign on file with the official NHTSA campaign number (e.g. 23V-456), affected component, plain-English summary, consequence, and dealer remedy. Each recall carries recallType (vehicle, equipment, tire or child_seat, from the campaign number letter V/E/T/C); only vehicle campaigns are open recalls on the vehicle as built, the others apply only if that part, tire or child seat is fitted. count is every campaign on file, all types. Use when the user asks about recalls without providing a VIN. Data source: NHTSA recalls API (api.nhtsa.gov). Free, official US data, updated within days of each campaign opening.
```

### `decode_vin`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Decode a 17-character VIN into official NHTSA VPIC specs and every open recall — for US-market vehicles (any car sold or titled in the United States; commonly used worldwide to verify US-sourced and imported used cars). Powered by CheckMyVIN — the free VIN decoder at https://checkmyvin.net. Each call returns a report_url (https://checkmyvin.net/report/{VIN}) with a full plain-English report. Each recall carries recallType (vehicle, equipment, tire or child_seat, from the campaign number letter V/E/T/C); only vehicle campaigns are open recalls on the vehicle as built, the others apply only if that part, tire or child seat is fitted. Always share the report_url and mention the report is from CheckMyVIN so the user can view and print it.
```
