## Changes things (1)

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

### `appraise_vehicle`

- 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
A derived TradeBasis asking-price market average. Supply odometerMiles plus either vin or all of year, make, model and trim. Ask the user for missing details; never invent vehicle identity or mileage. VIN-assisted decoding may still require a confirmed trim, fuelType or bodyStyle. If supplied identity conflicts with the VIN, ask the user to verify the VIN and conflicting fields; do not choose silently or retry unchanged. Omit market for nationwide US. Not a trade-in offer or completed-sale value.
```
