Skill Coverage

Core Features (SKILL.md)

• JWT generation and validation with multiple algorithms (RSA, HMAC, ECDSA)
• Bearer token and cookie-based authentication patterns
• Database-backed and OAuth2 provider integration
• Both RBAC and permission-based access control
• Advanced patterns: refresh tokens, token rotation, multi-tenancy

Configuration (jwt-configuration.md)

• Comprehensive dependency management
• Key configuration for RSA, HMAC, and ECDSA
• Custom claims and validation
• Application properties and YAML configurations
• Key rotation support

Implementation Examples (examples.md)

• Complete application setup
• Domain models (User, Role, Permission entities)
• Authentication and registration controllers
• Service layer implementations
• Advanced security configuration

Authorization Patterns (authorization-patterns.md)

• Hierarchical role structures
• Custom permission evaluators
• Attribute-Based Access Control (ABAC)
• Time-based access control
• Location-based restrictions
• Organizational access control

Token Management (token-management.md)

• Secure refresh token storage
• Token rotation strategies
• Token blacklisting
• Session management
• Distributed security events

Microservices Security (microservices-security.md)

• Inter-service authentication
• API gateway patterns
• Distributed token validation
• Service mesh integration (Istio)
• Circuit breaker patterns

OAuth2 Integration (oauth2-integration.md)

• Multi-provider support

• Debugging checklist

Integration Points

This skill integrates with:

1. Spring Boot Actuator - For security monitoring and health checks
2. Spring Data JPA - For user and token persistence
3. Spring Cache - For token validation caching
4. JUnit Testing - For comprehensive security testing
5. LangChain4j - For AI-powered security analysis (if needed)

Quick Start Flow

1. Review README.md for overview
2. Generate keys using ./assets/generate-jwt-keys.sh
3. Implement basic JWT using SKILL.md quick start
4. Reference jwt-configuration.md for detailed setup
5. Use examples.md for implementation patterns
6. Apply security-hardening.md for production
7. Run tests with ./scripts/test-jwt-setup.sh
8. Monitor with troubleshooting.md as needed

Key Benefits

1. Comprehensive Coverage: From basic JWT to advanced microservices patterns
2. Production Ready: Includes security hardening and performance optimization
3. Well Documented: Each aspect has detailed reference documentation
4. Practical Examples: Real-world code implementations
5. Testing Included: Automated test suite and testing strategies
6. Troubleshooting Guide: Common issues and solutions

Maintenance

This skill should be updated when:

• New Spring Security features are released
• New security vulnerabilities are discovered
• Performance optimizations are identified
• Community feedback suggests improvements
• Integration patterns evolve
