Nexus Safe

Provides local system health monitoring and controlled service restarts for Docker and PM2 with full privacy and zero external calls.

Skill: Nexus-Safe (V1.3.0)

Autonomous local System Reliability Agent for OpenClaw.

🛡️ Privacy & Security Policy

• Runtime Privacy: Strictly 100% local. No metrics, logs, or system data ever leave your server. No outbound network calls are performed by the script.
• Setup Notice: An internet connection is required only during initial setup to install the psutil dependency via pip.
• Safe-by-default: Recovery actions are locked until explicitly enabled.

📋 Capabilities

• /nexus-safe status : Real-time system health (CPU, RAM, Disk, Load).
• /nexus-safe logs <service> : Diagnostic log retrieval (Docker/PM2).
• /nexus-safe recover <service> : Policy-controlled service restart.

⚙️ Logic & Enforcement

• Allowlist Required: Restarts only work for services in NEXUS_SAFE_ALLOWED_DOCKER/PM2.
• Logs-First Policy: The tool blocks recovery if logs haven't been reviewed within the last 5 minutes.
• Rate Limiting: Sliding window protection (Max 3 restarts per hour).

🚀 Installation

1. pip install psutil
2. Ensure docker and pm2 are installed and in your PATH.
