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)

Common Workflows

Secure Web Application

Sequence: Authentication → Authorization → Input validation → Security headers

cat ~/.claude/skills/security/authentication.md        # User login
cat ~/.claude/skills/security/authorization.md         # Access control
cat ~/.claude/skills/security/input-validation.md      # XSS/SQL injection prevention
cat ~/.claude/skills/security/security-headers.md      # Browser protection

Security Audit

Sequence: Vulnerability assessment → Input validation → Headers → Secrets

cat ~/.claude/skills/security/vulnerability-assessment.md  # OWASP Top 10 testing
cat ~/.claude/skills/security/input-validation.md          # Injection testing
cat ~/.claude/skills/security/security-headers.md          # Header configuration
cat ~/.claude/skills/security/secrets-management.md        # Credential security

API Security

Sequence: Authentication → Authorization → Input validation → Secrets

cat ~/.claude/skills/security/authentication.md        # JWT/OAuth2
cat ~/.claude/skills/security/authorization.md         # API access control
cat ~/.claude/skills/security/input-validation.md      # Request validation
cat ~/.claude/skills/security/secrets-management.md    # API key management

DevSecOps Pipeline

Sequence: Vulnerability assessment → Secrets → Input validation

cat ~/.claude/skills/security/vulnerability-assessment.md  # Security scanning
cat ~/.claude/skills/security/secrets-management.md        # CI/CD secrets
cat ~/.claude/skills/security/input-validation.md          # SAST validation

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.
