+# Sysadmin Toolbox
+
+Curated tool recommendations and practical shell one-liners for operational work.
+
+## When to Auto-Consult
+
+Load relevant references when user is:
+- Debugging network connectivity, ports, traffic
+- Troubleshooting DNS or SSL/TLS
+- Analyzing processes, memory, disk usage
+- Working with logs or system diagnostics
+- Writing shell scripts or one-liners
+- Asking "what's a good tool for..."
+- Doing security audits or pentesting
+- Working with containers/Docker/K8s
+
+## Reference Files
+
+| File | Use When |

+## 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
