By name: health description: > 10-second audit of dev server system state. Use when: "health check", "system status", "check system", "what's running", "orphans", "disk space", "check containers", or any question about the current state of the server.
System Health Check
Run ALL checks in parallel (single Bash call with semicolons), then render one table.
Checks to Run
echo "=== DOCKER ===" && docker ps --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}" 2>/dev/null ; \
echo "=== CHROME ===" && curl -s --max-time 2 http://localhost:9222/json/version 2>/dev/null | python3 -c "import sys,json; d=json.load(sys.stdin); print(d.get('Browser','unknown'))" 2>/dev/null || echo "DOWN" ; \
echo "=== SSHFS ===" && ls /mnt/<your-mount> 2>/dev/null | head -1 || echo "NOT MOUNTED" ; \

Output Format
Render a single markdown table:
| Service | Status | Details |
|---|---|---|
| [container-1] | OK / DOWN | Container status + uptime |
| [container-2] | OK / DOWN | Container status + ports |
| Chrome :9222 | OK / DOWN | Browser version or "no response" |
| sshfs mount | OK / DOWN | Mount healthy or not mounted |
| Orphan processes | OK / N found | List PIDs + names if any |
| Disk / | X% used | Used/total, warn if >80% |
| /tmp largest files | OK / WARN | Top entries if >500MB |
| Failed systemd units | OK / N failed | Unit names if any |
| Memory | X GB free | Used/total |
| Stale worktrees | OK / N found | Names if any |
Status Rules
- OK: service running, mount healthy, no orphans, disk <80%, no failed units
- WARN: disk 80-90%, /tmp files >1GB, worktrees older than 7 days
- DOWN: container exited/missing, Chrome not responding, mount absent
- CRITICAL: disk >90%, memory <500MB free, P0 orphan processes (remotion/ffmpeg/whisper running without timeout)
After the Table
If any DOWN or CRITICAL items exist, list them as a bulleted action list:
- "[container] is DOWN: run
docker restart [container]" - "Chrome :9222 is DOWN: check
ps aux | grep chrome" - "Orphan found (PID 1234 - ffmpeg): kill with
kill 1234" - "sshfs not mounted: remount or check SSH connectivity"
If everything is OK, one line: "All systems nominal."
