sysadmin-toolbox
Tool discovery and shell one-liner reference for sysadmin, DevOps, and security tasks. AUTO-CONSULT this skill when the user is: troubleshooting network issues, debugging processes, analyzing logs, working with SSL/TLS, managing DNS, testing HTTP endpoints, auditing security, working with containers, writing shell scripts, or asks 'what tool should I use for X'.

- Gen Agent Trust Hubwarn
This skill provides a collection of system administration tools and shell one-liners. It includes a script that automatically downloads and updates its instructions from an external GitHub repository. While intended for legitimate DevOps use, this mechanism allows the skill's behavior to change based on remote content, and the toolbox contains powerful commands for system modification and network manipulation.

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
Bundled Guides
| File | Use When |
|---|---|
shell-oneliners.md in this skill's references folder | Need practical commands for: terminal, networking, SSL, curl, ssh, tcpdump, git, awk, sed, grep, find |
cli-tools.md in this skill's references folder | Recommending CLI tools: shells, file managers, network utils, databases, security tools |
web-tools.md in this skill's references folder | Web-based tools: SSL checkers, DNS lookup, performance testing, OSINT, scanners |

Safety Boundaries
- Do not run destructive system commands, privilege-escalation steps, or offensive tooling unless the user explicitly asked for that scope.
- Do not scan hosts, domains, or networks the user does not control or have permission to assess.
- Do not assume a command is safe to paste into production without explaining what it does.
- Do not persist logs, captures, or credentials outside the user's requested troubleshooting workflow.

Manual refresh anytime:
./scripts/refresh.sh [skill-dir]
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
