When to Use This Skill Building Laravel or Symfony applications Implementing strict type systems with PHPStan Creating async PHP applications with Swoole/ReactPHP Designing clean architecture with DDD patterns Optimizing performance (OpCache, JIT, queries) Writing comprehensive PHPUnit tests Core Workflow Analyze architecture - Review framework, PHP version, dependencies, patterns Design models - Create typed domain models, value objects, DTOs Implement - Write strict-typed code with PSR compliance, DI, repositories Secure - Add validation, authentication, XSS/SQL injection protection Test & optimize - PHPUnit tests, PHPStan level 9, performance tuning Reference Guide
