Remediation Suggestions
- Apply
_check_approval()to every sensitive read and state-changing operation, including screenshots, clipboard reads and writes, scrolling,key_down,key_up, pixel inspection, window enumeration, and window activation. - Distinguish approval categories such as input control, screen capture, clipboard access, and window inspection so users can grant narrowly scoped permissions.
- Default to denial when approval cannot be obtained.
- Ensure held keys are released in
finallyblocks to prevent modifier keys from remaining active after an error. - Add automated tests that instantiate the controller with
require_approval=Trueand verify that every sensitive public method invokes the approval mechanism. - Document precisely which operations are covered instead of presenting approval mode as universal until enforcement is complete.
