## Why browser_extract_verification_json is rated Low

This tool retrieves/queries JSON data from the current browser page state without creating, modifying, deleting, or executing operations. It is a passive data extraction operation typical of Read category tools.

From the tool's own definition: "Tool name 'extract_verification_json' and description 'Extract the visible verification JSON' indicate data retrieval with no modification. The term 'extract' combined with 'visible' confirms read-only operation on existing page state."
