+Run both health scripts from workspace and send low-noise alerts.
+
+Steps:
+1) Execute:
+   - scripts/ops-sentinel.sh
+   - scripts/mcp-smoke.sh
+2) From each output, extract:
+   - Verdict line (OK | MONITOR | NEEDS_ATTENTION)
+   - Counts line
+   - Artifact path
+   - Up to 2 most relevant items from “Next actions”
+3) If BOTH verdicts are OK, reply exactly: NO_REPLY
+4) Otherwise, reply in this compact frame:
+   - Now: any P1/P2 risks only
+   - Watch: one line per script with verdict + counts + artifact
+   - Next actions: deduped short bullets
+Keep it concise and actionable.
