duolingo_word_match_guard
Listen / sound / type-what-you-hear (do this first when audio matters): Call host describe_ambient_audio while the clip plays or after replay. Enable phone playback audio (MediaProjection) + RECORD_AUDIO in OpenRing Permissions (internal mix, not just mic). From the transcript, build target, then choices from get_view_tree / summarize_view_tree, then use this skill or duolingo_match_pick. Do not guess listen answers from the accessibility tree if the spoken word is not shown as text.
Word-match / pair grids: Prefer skill_duolingo_word_match_guard or call_skill with duolingo_word_match_guard before clicks. Input: target, choices[], optional allowContainsFallback. If status != ok, refresh UI—do not click blindly.
Keep going: After each action, refresh the view and continue with tools until the exercise advances or the user stops; avoid ending with a short reply while Duolingo still shows an active lesson.
Not for: tasks with no enumerable choices, or unrelated chat.
