What is Nexus-Safe?
Nexus-Safe is a specialized Openclaw Skills addition designed for developers and system administrators who prioritize local system reliability and security. It acts as an autonomous guardian for your infrastructure, monitoring critical metrics like CPU, RAM, and disk usage while providing controlled recovery mechanisms for Docker and PM2 services without compromising privacy.
This skill ensures that your server management remains strictly local. By enforcing a logs-first policy and rate limiting, Nexus-Safe prevents accidental or runaway recovery actions, making it an essential tool for maintaining high availability in production and development environments.
Nexus-Safe Use Cases
- Monitoring real-time system health metrics including CPU load, RAM usage, and disk availability.
- Diagnosing service failures by retrieving Docker or PM2 logs directly through the agent interface.
- Executing policy-controlled service restarts when critical issues are detected in production environments.
- Maintaining local-only system management to ensure data privacy and security for sensitive infrastructure.
How Nexus-Safe Works
- The agent monitors system health using the psutil library to track hardware utilization and system load averages.
- Users request diagnostic logs for specific Docker or PM2 services via the integrated command interface.
- The system enforces a security check ensuring logs were reviewed within the last 5 minutes before allowing any recovery actions.
- If the service is on the pre-defined allowlist, the agent executes a restart while staying within a sliding window rate limit of 3 restarts per hour.
Nexus-Safe Setup
To install Nexus-Safe for your Openclaw Skills environment, follow these steps:
- Install the core system dependency using pip:
pip install psutil
- Ensure your system has the necessary service managers installed and accessible in your environment PATH:
docker --version
pm2 --version
- Configure your service allowlist in the environment variables to enable the recovery functionality safely.
Nexus-Safe Data Schema & Taxonomy
Nexus-Safe operates with a focus on runtime privacy, storing minimal state locally to enforce its safety policies. It organizes data according to the following taxonomy:
| Data Category | Details | Persistence |
|---|---|---|
| Health Metrics | Real-time CPU, RAM, and Disk stats | Transient (In-memory) |
| Service Logs | Diagnostic output from Docker/PM2 | Local system logs only |
| Safety State | Timestamps of recent recovery actions | Local state file |
| Configuration | Allowlisted services (NEXUS_SAFE_ALLOWED) | Environment variables |
Nexus-Safe Advanced Features
- Logs-First Policy: Mandatory diagnostic review requirement before any recovery action is permitted to prevent blind restarts.
- Sliding Window Protection: Automatic rate limiting that prevents restart loops by capping actions at 3 per hour.
- Strict Local Runtime: 100% telemetry-free operation ensuring no system data ever leaves your local server environment.
- Multi-manager Support: Seamless native integration with both Docker container environments and PM2 process managers.
