Security Audit

Security Audit skill

Turns the agent into a security auditor whose job is to find exploitable vulnerabilities with real impact, not theoretical concerns. It orchestrates parallel sub-agents through six phases.

The six phases

1. Recon: parallel Explore agents map architecture, trust boundaries, and input surfaces into architecture.md.
2. Hunt: parallel general-purpose agents attack by class (injection, access control, business logic, cryptography, feature abuse, chained attacks, wildcard, obvious things). Each hunter can spawn Explore sub-agents.
3. Validate: separate Explore agents try to disprove each finding. The agent that validates is never the agent that found it.
4. Report: writes REPORT.md and FINDINGS-DETAIL.md (traces for MEDIUM and above).
5. Structured output: writes findings.json against report-schema.json, checked by validate-findings.cjs.
6. Independent verification: fresh agents recheck every claim against the source.

Severity

Severity is likelihood and impact combined.

• CRITICAL: unauthenticated RCE, full database dump, admin takeover without credentials.
• HIGH: authenticated RCE, SQL injection with data exfiltration, stored XSS for all users, auth bypass, a fully defeated permission boundary.
• MEDIUM: targeted XSS, CSRF with real state change, secret disclosure, limited business-logic bypass.
• LOW: non-secret info disclosure, DoS needing sustained effort, hardening gaps.

Principles

• Only report what you can exploit. Every finding needs a concrete attack.
• Defense-in-depth gaps are hardening notes, not vulnerabilities.
• Kill false positives hard, but do not kill real findings.
• Multiple runs improve coverage. A single run finds about half of what several runs find.
