## Why search_facilities is rated Low

This tool performs a query operation on a public health directory of treatment facilities. It retrieves and filters existing data based on search parameters (state, city, treatment type, insurance) and returns informational results. There is no capability to modify, delete, execute code, or commit financial transactions.

From the tool's own definition: "Tool description states it 'Search' and 'Returns matched facilities' with publicly available information (name, city/state, programs, insurance, phone, URL). No modification, deletion, or execution of external operations occurs."

## Use case
