## Why sok_eiendom is rated Low

This is a geographic data lookup tool that queries Norwegian property registry information (Matrikkel) and returns read-only results. It has no side effects, does not modify data, and does not execute code or external operations. The data returned is public geographic and cadastral information.

From the tool's own definition: "Tool description states it looks up property records ('matrikkeleiendom') via geographic coordinates or property identifiers and returns property numbers, local IDs, and representation points. No modification, deletion, or execution capabilities are described."

## Use case
