What problem does it solve?

This Skill guides reviewers in assessing React Router code for proper data loading, mutations, error handling, and navigation patterns.

Core Features & Use Cases

• Data loaded via loader patterns vs useEffect and proper defer usage.
• Mutations with Form/useFetcher patterns and robust action handling.
• Error boundaries with errorElement and proper error types.
• Declarative navigation with Link and appropriate pending states.

Quick Start

Review route definitions to ensure loaders handle errors, mutations use Form/useFetcher, and navigation uses Link over imperative navigation where possible.
