# Subdomain Enumeration Skill

Comprehensive subdomain discovery using certificate transparency logs (crt.sh), DNS brute force, and passive sources. The first step in any recon pipeline — you can't attack what you don't know exists. Subdomain enumeration consistently reveals staging environments, internal admin panels, API gateways, and forgotten WordPress installs that are softer targets than the production site.

## When to Use

- Starting recon on any target domain.
- Production site is well-secured — find softer entry points.
- After `skill_view(name='wp-mass-recon')` — enumerate subdomains for each WordPress target.
- Building a complete asset inventory for a target organization.

## Prerequisites

- `curl`, `httpx`, `dig`, `jq`, `dnsx`, and `subfinder`.
