Analyze feature requirements, dependencies, and security considerations. Use when starting feature implementation from GitHub issues to understand scope, technical feasibility, and risks.
Design system architecture, API contracts, and data flows. Use when translating analyzed requirements into technical design for feature implementation.
Implement features with code, tests, and documentation. Use when building features from approved designs following TDD and project coding standards.
Validate code quality, test coverage, performance, and security. Use when verifying implemented features meet all standards and requirements before marking complete.
Validate WCAG 2.1 Level AA compliance and accessibility best practices. Use when performing accessibility audits and WCAG certification.
