Author: ex3ndr

Use the bundled helper for passive infrastructure questions.

Helper Script

python3 SKILL_DIR/scripts/domain_intel.py subdomains example.com
python3 SKILL_DIR/scripts/domain_intel.py ssl example.com
python3 SKILL_DIR/scripts/domain_intel.py whois example.com
python3 SKILL_DIR/scripts/domain_intel.py dns example.com
python3 SKILL_DIR/scripts/domain_intel.py available example.com
python3 SKILL_DIR/scripts/domain_intel.py bulk example.com github.com --checks ssl,dns

All output is structured JSON.

Use This For

passive subdomain discovery
certificate issuer and expiry checks
WHOIS and registrar metadata
DNS record inspection
quick availability heuristics

Use Other Tools For

web_search: company or domain background research
web_fetch: actual website content
exec with curl -I: simple HTTP reachability checks

Notes

WHOIS on port 43 may be blocked on some networks
Availability results are heuristic, not registrar-authoritative
crt.sh lookups can be slow for very large domains
