## Why resolve_trademark_subject is rated Low

The tool performs entity resolution, which is a read/query operation that matches input to existing trademark records. It retrieves data without creating, modifying, or deleting anything. The authentication requirement for certain lookups slightly elevates sensitivity but does not change the fundamental read nature of the operation. Severity is low as misuse would only expose trademark entity information.

From the tool's own definition: "'Resolve an owner, law firm, correspondent, mark, TTAB proceeding, client, or portfolio to the best trademark entity match' — this is a lookup/resolution operation that retrieves and matches data"

## Use case
