Preserve React 18 concurrent patterns and adopt React 19 APIs (useTransition, useDeferredValue, Suspense, use(), useOptimistic, Actions) during migration.
React 19 patterns and React Compiler behavior with Context shorthand syntax and use() hook. Use when working with Context, useContext, use() hook, Provider components, optimization patterns like useMemo, useCallback, memo, memoization, or when the user mentions React 19, React Compiler, Context.Provider, or manual optimization.
Reference for React 19 source-file migration patterns, including API changes, ref handling, and context updates.
Provides before/after patterns for migrating test files to React 19 compatibility, including act() imports, Simulate removal, and StrictMode call count changes.
Provides the complete, verified grep scan command library for auditing React codebases before a React 18.3.1 or React 19 upgrade. Use this skill whenever running a migration audit - for both the react18-auditor and react19-auditor agents. Contains every grep pattern needed to find deprecated APIs, removed APIs, unsafe lifecycle methods, batching vulnerabilities, test file issues, dependency conflicts, and React 19 specific removals. Always use this skill when writing audit scan commands - do not rely on memory for grep syntax, especially for the multi-line async setState patterns which require context flags.
React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs. Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.
Build Next.js 16 + React 19 + TinaCMS sites with visual editing, blocks-based page builder, and complete SEO. Use this skill whenever the user mentions TinaCMS, Tina CMS, Next.js with a CMS, visual editing with Next.js, click-to-edit, content-managed Next.js site, blocks pattern page builder, or migrating to Next.js + TinaCMS. Also trigger for TinaCMS schema design, self-hosted TinaCMS, TinaCMS media configuration, or any TinaCMS troubleshooting. Covers Day 0-2 setup from scaffolding through production deployment on Vercel.
Core React 19 patterns including hooks, Suspense, lazy loading, component structure, TypeScript best practices, and performance optimization. Use when working with React components, hooks, lazy loading, Suspense boundaries, or React-specific TypeScript patterns.
Expert code reviewer for TypeScript + React 19 applications. Use when reviewing React code, identifying anti-patterns, evaluating state management, or assessing code maintainability. Triggers: code review requests, PR reviews, React architecture evaluation, identifying code smells, TypeScript type safety checks, useEffect abuse detection, state management review.
