Example Queries → Actions

"Why is this port not responding?" → Load shell-oneliners.md, search for netstat/ss/lsof commands

"What's a good tool for testing SSL?" → Load cli-tools.md SSL section, recommend testssl.sh or sslyze

"Show me how to find large files" → Load shell-oneliners.md, search for find/ncdu/du commands

"I need to debug DNS resolution" → Load shell-oneliners.md dig section + recommend dnsdiag from cli-tools.md
