OpenClaw Skills for React Developers: The Essential List

If you write React every day, your AI agent should know React as well as you do — ideally better. General-purpose agents can generate JSX and handle basic hooks, but they stumble on the patterns that experienced React developers rely on: custom hook composition, render optimization, proper testing with React Testing Library, and the architectural decisions that keep a codebase maintainable at scale.

OpenClaw skills close that gap. Each skill listed here teaches your agent specific React knowledge so it writes code the way a senior React developer would. These are the most-installed React skills on the OpenClaw Bazaar, ranked by community adoption and rating.

Hooks Patterns

react-hooks-patterns

Installs: 18,400 | Author: composable-dev

This skill is the single most popular React skill on the Bazaar, and for good reason. It teaches your agent how to write, compose, and refactor custom hooks following the patterns that the React team recommends.

Without this skill, agents tend to dump all logic into component bodies or create hooks that violate the rules of hooks in subtle ways — calling hooks conditionally, nesting them inside callbacks, or returning unstable references that trigger unnecessary re-renders.

With react-hooks-patterns installed, your agent will:

• Extract reusable logic into custom hooks with stable return signatures
• Use useCallback and useMemo only where they provide measurable benefit, not as a default
• Compose hooks by calling simpler hooks from more complex ones
• Handle cleanup properly in useEffect, including race condition prevention for async operations
• Implement the reducer pattern with useReducer when state transitions are complex

react-use-effect-mastery

Installs: 9,200 | Author: effectful-io

The most common React bugs in production come from misused effects. This skill focuses exclusively on useEffect — when to use it, when not to use it, and how to structure dependencies correctly.

The skill teaches your agent to distinguish between effects that synchronize with external systems (the correct use case) and effects that derive state from other state (an anti-pattern). It also covers the newer React patterns for handling data fetching without effects, using Suspense and server components where appropriate.

Key behaviors this skill enables:

• Recognizing when an effect should be replaced with an event handler
• Structuring dependency arrays correctly without relying on ESLint suppressions
• Implementing abort controllers for fetch-based effects
• Avoiding the stale closure problem in effects that reference changing state

State Management

react-state-architecture

Installs: 14,700 | Author: statewright

State management is where React projects either stay clean or become tangled. This skill gives your agent a decision framework for choosing the right state strategy — local state, lifted state, context, or an external store — based on the specific requirements of each feature.

Rather than defaulting to a single library, the skill teaches your agent to evaluate tradeoffs:

• Local state for UI-only concerns like form inputs and toggle visibility
• Lifted state when siblings need to share data
• Context for low-frequency updates like themes and auth status
• External stores (Zustand, Jotai, Redux Toolkit) for high-frequency shared state

The skill includes patterns for each of these approaches and teaches the agent to migrate between them as requirements change — for instance, promoting local state to a Zustand store when a feature grows beyond a single component tree.

react-zustand-patterns

Installs: 11,300 | Author: zustand-community

If your team has already chosen Zustand, this skill goes deep on idiomatic usage. It covers store slicing, middleware composition, persist middleware configuration, and the subscribe API for integrating with non-React code.

The skill produces stores that follow the Zustand team's recommended patterns: small slices combined into a root store, selectors that prevent unnecessary re-renders, and typed middleware chains that preserve TypeScript inference.

Testing with React Testing Library

react-testing-library-expert

Installs: 16,800 | Author: test-craft

This is the second most installed React skill on the Bazaar. It teaches your agent to write tests that mirror how users interact with your components — not implementation details.

Without this skill, agents write tests that query by class name, check internal state, or test implementation details that break on every refactor. With it installed, your agent:

• Queries elements by role, label text, and placeholder — never by test ID unless there is no semantic alternative
• Uses userEvent instead of fireEvent for realistic interaction simulation
• Writes assertions against visible output, not internal component state
• Structures tests in the Arrange-Act-Assert pattern
• Handles async operations with waitFor and findBy queries correctly
• Mocks API calls at the network level using MSW (Mock Service Worker) rather than mocking fetch directly

The skill also covers snapshot testing guidelines — specifically, when snapshots add value (small, stable components) and when they create maintenance burden (large, frequently changing components).

react-vitest-setup

Installs: 7,600 | Author: vitest-react

Pairs with react-testing-library-expert to handle the Vitest-specific configuration and patterns. It covers vi.mock for module mocking, vi.fn for function spies, and the @testing-library/jest-dom matchers setup for Vitest environments.

Performance Optimization

react-performance-patterns

Installs: 12,100 | Author: perfwright

Performance in React is not about adding React.memo everywhere. This skill teaches your agent to identify actual performance bottlenecks and apply the right optimization for each situation.

Core patterns the skill covers:

• Component splitting: breaking large components into smaller ones so React can skip re-rendering unchanged subtrees
• Virtualization: using libraries like TanStack Virtual for long lists instead of rendering thousands of DOM nodes
• Lazy loading: code-splitting with React.lazy and Suspense for routes and heavy components
• Memoization: applying useMemo and useCallback based on measured performance impact, not premature optimization
• State colocation: keeping state as close to where it is used as possible to minimize the re-render blast radius

The skill also teaches your agent to use React DevTools Profiler output. When you paste profiler results into your agent conversation, the skill helps interpret flamegraph data and suggest targeted optimizations.

react-server-components

Installs: 10,500 | Author: rsc-patterns

Server components are the biggest performance lever in modern React. This skill covers the mental model — what runs on the server, what runs on the client, and where to draw the boundary.

The skill teaches your agent to:

• Default to server components and only add "use client" when interactivity is required
• Pass serializable props across the server-client boundary
• Use server actions for mutations
• Structure component trees so client components are leaves, not roots
• Avoid common mistakes like importing client-only libraries in server components

Component Architecture

react-component-architecture

Installs: 13,200 | Author: arch-patterns

This skill addresses the structural decisions that determine whether a React codebase stays navigable at 200 components or becomes a maze. It teaches your agent a consistent component taxonomy:

• Page components: route-level components that compose features
• Feature components: business-logic containers that manage state and data fetching
• UI components: presentational components that receive data via props
• Layout components: structural components that handle spacing, grids, and responsive behavior

The skill also covers file organization conventions (collocating tests, styles, and types with components), barrel export patterns, and prop interface design — including when to use composition (children) versus configuration (props).

react-design-system-patterns

Installs: 8,900 | Author: ds-guild

For teams building or maintaining a design system, this skill teaches your agent to create components that are composable, accessible, and theme-aware. It covers the compound component pattern, polymorphic components with as props, and the slot pattern for flexible layouts.

The skill integrates well with Radix UI primitives and ensures your agent builds accessible components by default — proper ARIA attributes, keyboard navigation, and focus management.

Putting It All Together

The strongest React agent setup combines skills from each category. A recommended starting stack:

1. react-hooks-patterns for day-to-day hook authoring
2. react-testing-library-expert for test generation
3. react-state-architecture for state management decisions
4. react-performance-patterns for optimization guidance
5. react-component-architecture for structural consistency

Install all five and your agent will handle React code with the judgment of a senior developer — knowing not just the syntax, but the tradeoffs behind every pattern choice.
