 ## Execution
+### check-health
+
+**RUN LIVE, NEVER ECHO — every dispatch must execute the probes below with real tool calls; never repeat a prior report unless a live probe fails.**
+
+```bash
+# Zulip API health (POST ping)
+curl -s -o /dev/null -w '%{http_code}' -X POST https://chat.sysloggh.net/api/v1/messages -u 'abiba-bot@chat.sysloggh.net:KEY'
+# Expected: 200 (HTTP 000 = unreachable/cache)
+
+# PM2 process health
+pm2 jlist
+# Expected: 5/5 online (abiba-telegram, abiba-zulip, zulip-watchdog, gitea-runner, spoton-service)
+
+# GPU exporters (may be down per DEPLOYMENT STATUS)
+curl -s http://192.168.68.8:9400/metrics && echo " - OK" || echo " - FAIL"
+curl -s http://192.168.68.110:9400/metrics && echo " - OK" || echo " - FAIL"
+curl -s http://192.168.68.15:9400/metrics && echo " - OK" || echo " - FAIL"
+
+# Prometheus targets
+curl -s http://192.168.68.116:9090/api/v1/targets | jq '.data.activeTargets'
+# Expected: All targets UP (may show some down if exporters not deployed)
+
+# Grafana health
+curl -s http://192.168.68.116:3001/api/health | jq '{status, version}'
+# Expected: {"status":"ok","version":"..."}
+
+# LiteLLM metrics
+curl -s http://192.168.68.116:4001/metrics | head -20
+# Expected: Prometheus-formatted metrics output
+```
+
+**Report format**: Summarize actual results from each probe. If any probe returns non-200 or empty output, flag as alert.
