- command_executor
- network_diagnostics instructions: | Use this skill when the user needs to diagnose network connectivity issues, check DNS resolution, scan ports, trace routes to hosts, or verify HTTP endpoints. All operations use Node.js built-in modules (dns, net, os, child_process, http, https) with no external dependencies. Supports cross-platform operation on Windows, macOS, and Linux. examples:
- input: "/network-diagnostics --ping google.com --count 5" output: "Ping google.com: 5 packets sent, avg 12.3ms, min 10.1ms, max 15.8ms"
- input: "/network-diagnostics --dns example.com --type MX" output: "MX records for example.com: 10 mail.example.com"
- input: "/network-diagnostics --port localhost 5432" output: "Port 5432 on localhost: OPEN (PostgreSQL)"
- input: "/network-diagnostics --ports localhost --range 5170-5180" output: "Scan 5170-5180 on localhost: 5173 OPEN, 5174 CLOSED, ..."
- input: "/network-diagnostics --check https://api.example.com/health" output: "HTTP 200 OK (85ms) - https://api.example.com/health is reachable" dependencies: [] os: [win32, darwin, linux] author: ChainlessChain handler: ./handler.js
