network-diagnosis

What problem does it solve?

This Skill provides systematic network fault diagnosis by collecting and correlating multi-source telemetry (interfaces, routes, ARP, firewall, conntrack, MTU) to identify root causes.

Core Features & Use Cases

• Multi-source snapshot collection across interfaces, routes, ARP, DNS, and logs for accurate diagnostics.
• Phase-driven workflow with strict sequencing and cross-source validation to prevent premature conclusions.
• Generates structured root-cause reports with actionable remediation guidance for both single-interface issues and whole-host outages.
• Real-world use cases include diagnosing a specified interface going down, diagnosing intermittent connectivity across the server, and validating routing or firewall misconfigurations.

Quick Start

Run the diagnostic workflow to collect a complete network snapshot and begin analysis.
