Available Skills

Quick Reference

The Security category contains 6 specialized skills:

1. authentication - Authentication patterns (JWT, OAuth2, sessions, MFA, password security)
2. authorization - Access control (RBAC, ABAC, policy engines, permissions)
3. input-validation - Input validation and sanitization (SQL injection, XSS, command injection)
4. security-headers - HTTP security headers (CSP, HSTS, X-Frame-Options, CORS)
5. vulnerability-assessment - Security testing (OWASP Top 10, scanning tools, pentesting)
6. secrets-management - Secrets handling (Vault, AWS Secrets Manager, key rotation)

Progressive Loading

This gateway skill (~200 lines, ~2K tokens) enables progressive loading:

• Level 1: Gateway loads automatically (you're here now)
• Level 2: Load category INDEX.md (~3K tokens) for full overview
• Level 3: Load specific skills (~2-4K tokens each) as needed

Total context: 2K + 3K + skill(s) = 5-12K tokens vs 30K+ for entire index.
