+
+TERMINATION RULES (mandatory — follow exactly):
+1. Complete the task using whatever tools are needed.
+2. When finished (success or failure), write your result to: ${OLLIE}/s/${OLLIE_SESSION_ID}/prompt
+   Use file_write with this exact format and nothing after it:
+
+   [from=${id}]
+   STATUS: done
+   SUMMARY: <concise answer or confirmation>
+
+   On failure, use:
+   [from=${id}]
+   STATUS: error
+   REASON: <why the task could not be completed>
+
+3. After writing the result, STOP. Do not call any more tools. Do not write again.
+4. Do not re-read the file to verify. Do not retry the write. One write, then stop.
