About essential-tools
A toolkit and methodology skill for penetration testing across web, API, and binary analysis, with reporting standards. It requires availability checks for key tools during reconnaissance and documenting any resulting limitations.
Key features
- 01Burp Suite and Playwright testing workflows
- 02Static binary analysis and reverse engineering
- 03Nuclei exposure scanning
- 04sslscan TLS checks
- 05PTES, OWASP WSTG, and reporting standards
Use cases
- 01Conduct web or API penetration tests
- 02Automate browser testing and capture evidence
- 03Review TLS configuration and common exposures
- 04Prepare penetration testing reports to defined standards

Required-at-start tooling (web/API engagements)
Run an availability check before declaring recon complete:
command -v subfinder nuclei sslscan httpx; curl -s "https://crt.sh/?q=%25.${DOMAIN}&output=json" | head -c1
- Subdomain/CT enum: subfinder, certspotter, crt.sh
- TLS posture: sslscan
- Templated exposure: nuclei
If a tool-class is unavailable, record it as an explicit limitation — NEVER declare recon COMPLETE having skipped a whole class. Hand-rolled urllib is not a substitute (see skills/coordination/reference/principles.md 'Real tools before hand-rolled HTTP').
