+# Skill: infra-monitor
+
+Monitors server health and watches all Agent OS skills for staleness or errors. Runs on a cron schedule on 172.27.40.3.
+
+## Inputs
+
+Reads before executing:
+- `../../identity.md`
+- `../../brain.md`
+- `../../memory/persistent.md`
+- `learnings.md` (this skill's improvement notes)
+
+## What to check
+
+### Docker health (on 172.27.40.3)
+- All expected containers are running (not exited/restarting)
+- Flag any container that has restarted more than 3 times in the last hour
+- Expected containers: portainer, nginx-proxy-manager, uptime-kuma, gitea, headscale, netbird, vaultwarden, flowise, plane, zabbix, homarr
+
+### Service reachability
+Lightweight HTTP check (curl, timeout 5s) on each internal URL:
+- http://172.27.40.3:9443 (Portainer)
+- http://172.27.40.3:3002 (Uptime Kuma)
+- http://172.27.40.3:3000 (Gitea)
+- http://172.27.40.3:3010 (Flowise)
+- http://172.27.40.3:7575 (Homarr)
+- http://172.27.6.139:11434 (Ollama)
+
+### Agent watchdog
+For each skill directory under `../../skills/`:
+- Check `last-output.md` modification time — flag if older than expected schedule
+- Check `../../logs/<skill-name>/` for ERROR entries in last run
+- Report: healthy / stale / erroring
+
+### System resources (on 172.27.40.3)
+- Disk usage on / — warn if >80%, critical if >90%
+- Memory usage — flag if >85%
+
+## Output
+
+Write a digest to `last-output.md` in this format:
+- Summary line: X healthy, Y warnings, Z critical
+- Section per category: Docker, Services, Agent Watchdog, System
+- Each item: ✓ OK / ⚠ Warning / ✗ Critical + one line detail
+
+Pass anomalies to `context/handoff.md` for notification skill (future).
+
+## Wrap-up
+
+After writing output:
+1. Update `learnings.md` with anything that went wrong or could be improved
+2. Append a one-line log entry to `../../logs/infra-monitor.log`: `YYYY-MM-DD HH:MM | status | summary`
+3. Update `../../memory/notes-from-last-run.md`
+
+## Schedule
+
+- **Heartbeat:** every hour — checks Docker + Ollama only (fast, <30s)
+- **Full digest:** daily at 07:00 — all checks
