react-modernization

Quick Review

Excellent React modernization skill with comprehensive coverage of upgrade paths, class-to-hooks migration patterns, and React 18 concurrent features. The description clearly conveys when to use the skill, and the content provides detailed code examples for common migration scenarios including lifecycle method conversions, context API updates, and performance optimization. The structure is well-organized with logical sections and a practical migration checklist. Task knowledge is strong with actionable codemod commands, TypeScript migration examples, and best practices. Novelty is solid—automating React modernization with codemods and handling complex concurrent features would be token-intensive for a CLI agent. Minor improvement areas: could benefit from the referenced files being present to provide even deeper domain knowledge (though their absence doesn't significantly detract), and some advanced edge cases (e.g., legacy context API, error boundaries migration) could be expanded. Overall, this is a high-quality, production-ready skill that would save significant time and tokens during React modernization tasks.
