Phase 3 of disciplined development. Executes approved implementation plansstep by step. Each step includes tests, follows the design exactly, andproduces reviewable commits.

Reference the project's defined technology stack including frameworks, languages, databases, testing tools, and deployment infrastructure. Use this skill when making technology decisions or choosing libraries. When working with project configuration files like package.json, requirements.txt, or Gemfile. When setting up new features that need to align with existing technology choices. When onboarding to understand the project's technical foundation. When choosing tools for testing, linting, CI/CD, or third-party services.

Structure React 19+ components following best practices for organization, state management, props handling, and code readability with top-down structure and single responsibility principle. Use this skill when creating new React components, refactoring existing components, organizing component logic, managing component state, defining prop interfaces (IComponentProps with I prefix), or implementing component patterns. Apply when working on React component files (*.tsx, *.jsx), Shadcn/ui components, or any frontend component implementations. This skill ensures predictable top-down structure (imports → types/interfaces → component → hooks → derived values → JSX), proper props destructuring with defaults in function signature, manageable component size (split at >300 lines), composition via Shadcn Slot pattern (asChild prop), React 19 patterns (use() hook for promises, useActionState for forms, useOptimistic for immediate feedback), no manual useMemo/useCallback (React Compiler handles memoization), Server Compo
