Provides a dedicated reference guide per SOLID letter (SRP file-splitting, OCP composition/render-props, LSP contract compliance, ISP role-based props/context, DIP constructor injection via Context) plus 10 ready-to-copy templates covering components, hooks, services, stores, validators, factories, and tests. This is a cross-cutting code-quality skill, not a feature skill — for the React APIs themselves see react-19, react-state, react-forms, and react-tanstack-router.

SOLID React - Component Architecture

Codebase Analysis (MANDATORY)

Before ANY implementation:

1. Explore project structure to understand architecture
2. Read existing related files to follow established patterns
3. Identify naming conventions, coding style, and patterns used
4. Understand data flow and dependencies

DRY - Reuse or Create Shared (MANDATORY)
