Overview

This skill automates React Context setup tasks and delivers step-by-step guidance, production-ready code, and validations for state sharing in React apps. It is an auto-activating Frontend Development assistant focused on reliable context patterns, performance, and accessibility. Use it to standardize context creation, provider wiring, and consumption across components.

How this skill works

The skill inspects requested context requirements (state shape, actions, async needs) and generates a minimal yet extensible Context + Provider implementation. It creates hooks for consumption, optional reducer patterns, TypeScript typings when requested, and basic tests or validation checks. It also recommends wiring, memoization, and splitting strategies to avoid unnecessary re-renders.

When to use it

  • You need a new global or feature-scoped React Context (auth, theme, settings, cart).
  • You want a consistent Context + Provider + hook pattern across a codebase.
  • You need to migrate prop drilling to Context or refactor for performance.
  • You want TypeScript-safe context types, reducers, or async actions.
  • You need validation, tests, or configuration for context usage in apps.

Best practices

  • Keep context value minimal: expose only what consumers need to reduce re-renders.
  • Use separate contexts for unrelated concerns (e.g., auth vs UI state).
  • Wrap expensive values with useMemo/useCallback and avoid placing non-serializable values directly in context.
  • Prefer custom hooks (useXContext) for consumption and throw descriptive errors when used outside a Provider.
  • Provide TypeScript interfaces or PropTypes for clarity and safer refactors.

Example use cases

  • Generate an AuthContext with signIn/signOut async flows and persisted storage integration.
  • Create a ThemeContext with system preference detection, toggle action, and CSS variable injection.
  • Refactor a component tree to replace prop drilling with a scoped SettingsContext and consumer hooks.
  • Produce TypeScript Context + reducer template with unit tests and example consumption patterns.
  • Split a large AppContext into focused contexts (UI, DataCache, Notifications) to improve performance.

FAQ

Will the skill output TypeScript or JavaScript?

It can generate both; specify TypeScript to include typings and interfaces, otherwise it will produce plain JavaScript.

How does it help avoid re-render issues?

The skill recommends splitting contexts, memoizing values, and using reducers or selectors so consumers only read required slices of state.

Can it create tests and validations?

Yes. It can add basic unit tests and validation checks to ensure context values meet expected shapes and required fields.
