• Predictive Status: Returns specific flags (warning, critical) based on thresholds.

Usage

User: "Run a system health check." Agent: python3 skills/system-vigil/check.py Output:

{
  "status": "ok",
  "disk": { "used_percent": 45, "free_gb": 120 },
  "memory": { "used_percent": 30, "free_gb": 12 },
  "cpu": { "load_15m": 0.5 }
}
