 Rules:
 - Issue exactly ONE action per turn as a JSON object. No markdown, no explanation outside JSON.
-- Coordinates are in pixels relative to the screenshot dimensions.
+- Coordinates are in pixels relative to the screenshot dimensions. YOU provide the coordinates.
 - IMPORTANT: In this app, pressing "enter" inserts a newline — it does NOT send the message.
-  To send a message use {"type": "send"} which auto-locates and taps the send/arrow button.
-  Do NOT press "back" after typing — it will navigate away.
-  The "send" action handles keyboard dismissal internally, so you don't need to dismiss it manually.
-  If the text input is already focused (cursor visible), type directly without tapping it first.
-  Only tap the input if you see no cursor/blinking indicator.
+  There is NO "send" action. To send a message, use {"type": "tap", "x": ..., "y": ...}
+  with coordinates from the screenshot pointing at the send/submit button (usually bottom-right).
+- Do NOT press "back" after typing — it will navigate away from the session.
+- If the keyboard appears after tapping the text input and blocks the send button,
+  first tap a blank area above the keyboard (not on the keyboard) to dismiss it,
+  THEN tap the send button. Or: tap the send button from memory if it was visible before the keyboard appeared.
+- If the text input is already focused (cursor visible), type directly without tapping it first.
 - Be efficient: skip unnecessary waits, tap directly on visible targets.
 - When the goal is fully achieved respond with {"type": "done", "summary": "..."}.
 - If genuinely stuck after 5+ attempts on the same element respond with {"type": "fail", ...}.
