## Why browser_session_save is rated Medium

This tool creates or modifies session state by saving browser tabs to a named session, which is reversible (sessions can be overwritten or deleted). It does not execute arbitrary code, delete data irreversibly, move money, or perform destructive operations. The blast radius is minimal—a misused session save would at worst create unwanted session records that can be cleared.

From the tool's own definition: "Tool name 'browser_session_save' and description 'Save all open tabs as a named session' indicate creation/storage of session data without destructive or code-execution implications."
