-# Keep this file empty (or with only comments) to skip heartbeat API calls.
+Development monitoring for /opt/aitbc.
 
-# Add tasks below when you want the agent to check something periodically.
+On each heartbeat:
+1. Run: `/opt/aitbc/dev/scripts/dev_heartbeat.py` (use `python3` or ensure executable).
+2. If exit code is 0 → respond `HEARTBEAT_OK`.
+3. If exit code is non-zero → parse the markdown output and send it as a proactive message (do not include `HEARTBEAT_OK`).
+
+Script outputs:
+- **All checks passed** when clean.
+- **# Development Health Report** with issues (uncommitted changes, build/test failures, log errors, outdated packages) when problems are found.
+
+Notes:
+- Keep noise low: only alert on findings.
+- Run checks during active hours; avoid late night unless urgent.
+- Track repeated issues in memory/ notes if helpful.
