description	Scoped host-level reconnaissance with the bundled Nmap distribution. Use when the operator explicitly asks for nmap, port scanning, service enumeration, host reachability checks, or low-risk host discovery on authorized targets.

Nmap Recon

Use this skill for low-risk host reconnaissance inside the authorized scope.

Workflow

1. Call list_skill_scripts(skill_name="nmap-recon") if you need to confirm the packaged script names.
2. Run scripts/nmap_status.py through run_skill_script first to confirm the bundled binary is available.
3. Run scripts/nmap_scan.py through run_skill_script for actual scans.
4. Scan only explicit in-scope hosts. Prefer a single host unless there is a clear reason to batch.
5. Start conservatively:
   • Use top_ports before broad ports ranges.
   • Keep service_version=true when service fingerprinting matters.
   • Keep os_detection=false unless the operator clearly needs OS guesses.
6. Treat skip_host_discovery=true as a fallback for hosts that block ping discovery.
7. Review the saved artifacts under artifacts/.../nmap/ and summarize only evidence-backed conclusions.

Notes

• The bundled scripts/ directory is for deterministic helper logic. Use list_skill_scripts to inspect it.
• run_skill_script(skill_name="nmap-recon", script_name="nmap_scan.py", args_json='["--target","app.example.internal","--top-ports","20"]') is the preferred scan entrypoint.
• nmap_scan.py enforces scope, rejects CIDR ranges, and records structured artifacts.
• Results are saved as .xml, .txt, and .json, plus an nmap-log.jsonl audit trail.
• If the scan returns ok=false, inspect stderr, parse_error, and the saved text output before concluding the host is unreachable.
• Prefer this packaged scripted workflow over writing one-off sandbox scan code when the task is clearly host or port reconnaissance.
