WHAT IT DOES

What get_frontmost_app does on Iconnect

RISK

Why get_frontmost_app is rated Low

This tool only retrieves read-only information about the active application. It has no side effects, does not modify state, and does not execute code or trigger external operations. The information returned (app name, bundle ID, PID) is system metadata that any process can query.

From the tool's definition Tool description states 'Get the name, bundle identifier, and PID of the currently active (frontmost) application.' This is a pure query operation that retrieves application metadata without modifying or executing anything.
