wor","description":"# Sysadmin Toolbox\n\nCurated tool recommendations and practical shell one-liners for operational work.\n\n## When to Auto-Consult\n\nLoad relevant references when user is:\n- Debugging network connectivity, ports, traffic\n- Troubleshooting DNS or SSL/TLS\n- Analyzing processes, memory, disk usage\n- Working with logs or system diagnostics\n- Writing shell scripts or one-liners\n- Asking \"what's a good tool for...\"\n- Doing security audits or pentesting\n- Working with containers/Docker/K8s\n\n## Bundled Guides\n\n| File | Use When |\n|------|----------|\n| `shell-oneliners.md` in this skill's `references` folder | Need practical commands for: terminal, networking, SSL, curl, ssh, tcpdump, git, awk, sed, grep, find |\n| `cli-tools.md` in this skill's `references` folder | Recommending CLI tools: shells, file managers, network utils, databases, security tools |\n| `web-tools.md` in this skill's `references` folder | Web-based tools: SSL checkers, DNS lookup, performance testing, OSINT, scanners |\n| `security-tools.md` in this skill's `references` folder | Pentesting, vulnerability scanning, exploit databases, CTF resources |\n| `shell-tricks.md` in this skill's `references` folder | Shell scripting patterns and tricks |\n\n## Safety Boundaries\n\n- Do not run destructive system commands, privilege-escalation steps, or offensive tooling unless the user explicitly asked for that scope.\n- Do not scan hosts, domains, or networks the user does not control or have permission to assess.\n- Do not assume a command is safe to paste into production without explaining what it does.\n- Do not persist logs, captures, or credentials outside the user's requested troubleshooting workflow.\n\n## Quick Tool Index\n\n### Network Debugging\n- `mtr` - traceroute + ping combined\n- `tcpdump` / `tshark` - packet capture\n- `netstat` / `ss` - connection monitoring\n- `nmap` - port scanning\n- `curl` / `httpie` - HTTP testing\n\n### DNS\n- `dig` / `host` - DNS queries\n- `dnsdiag` - DNS diagnostics\n- `subfinder` / `amass` - subdomain enumeration\n\n### SSL/TLS\n- `openssl` - certificate inspection\n- `testssl.sh` - TLS testing\n- `sslyze` - SSL scanning\n- `certbot` - Let's Encrypt\n\n### Process/System\n- `htop` / `btop` - process monitoring\n- `strace` / `ltrace` - syscall/library tracing\n- `lsof` - open files/connections\n- `ncdu` - disk usage\n\n### Log Analysis\n- `lnav` - log navigator\n- `GoAccess` - web log analyzer\n- `angle-grinder` - log slicing\n\n### Containers\n- `dive` - Docker image analysis\n- `ctop` - container top\n- `lazydocker` - Docker TUI\n\n## Keeping Current\n\nReferences auto-refresh weekly (Sundays 5am ET) from the upstream repo:\n```bash\n~/clawd-duke-leto/skills/sysadmin-toolbox/scripts/refresh.sh\n```\n\nManual refresh anytime:\n```bash\n./scripts/refresh.sh [skill-dir]\n```\n\n## Example Queries → Actions\n\n**\"Why is this port not responding?\"**\n→ Load shell-oneliners.md, search for netstat/ss/lsof commands\n\n**\"What's a good tool for testing SSL?\"**\n→ Load cli-tools.md SSL section, recommend testssl.sh or sslyze\n\n**\"Show me how to find large files\"**\n→ Load shell-oneliners.md, search for find/ncdu/du commands\n\n**\"I need to debug DNS resolution\"**\n→ Load shell-oneliners.md dig section + recommend dnsdiag from
