Frontend

Use when styling React Native Web components. Provides patterns for StyleSheet API, platform-specific styles, responsive design, and theming.

Use when erlang distributed systems including node connectivity, distributed processes, global name registration, distributed supervision, network partitions, and building fault-tolerant multi-node applications on the BEAM VM.

Use when bundling JavaScript/TypeScript code with Bun's fast bundler. Covers building for different targets, tree-shaking, code splitting, and optimization strategies.

Validates and configures all dependencies required for the Plugin Freedom System. This is a STANDALONE skill that runs BEFORE plugin workflows begin. It checks for Python, build tools, CMake, JUCE, and pluginval, optionally installing missing dependencies with user approval. Configuration is saved to .claude/system-config.json for use by other skills. Use when user mentions setup, installation, dependencies, missing tools, or when SessionStart hook detects configuration issues.

Use when building modular Angular applications requiring dependency injection with providers, injectors, and services.

Use when creating and managing Zustand stores for React state management. Covers store creation, selectors, actions, and basic usage patterns.

Use when relay fragment composition, data masking, colocation, and container patterns for React applications.

Use when optimizing React Native Web performance. Provides patterns for code splitting, bundle optimization, memoization, and web-specific performance improvements.

Use when creating or modifying GitHub Actions workflow files. Provides guidance on workflow syntax, triggers, jobs, steps, and expressions for creating valid GitHub Actions workflows that can be tested locally with act.

Use when querying data with Ecto.Query DSL including where clauses, joins, aggregates, preloading, and query composition. Use for building flexible database queries in Elixir applications.

Use when lua tables as the universal data structure including arrays, dictionaries, objects, metatables, object-oriented patterns, data structures, and advanced table manipulation for building flexible, efficient Lua applications.

Use when nestJS dependency injection with providers, modules, and decorators. Use when building modular NestJS applications.

Use when handling async operations in Angular applications with observables, operators, and subjects.

Use when swift's modern concurrency model including async/await, actors, task groups, structured concurrency, and async sequences for building safe, performant concurrent code without data races or callback pyramids.

Use when setting up or customizing Tailwind CSS configuration, theme customization, plugins, and build setup. Covers tailwind.config.js setup and content paths.

Use when Vue component patterns including props, emits, slots, and provide/inject. Use when building reusable Vue components.

Use when adding automated tests to CocoaPods libraries using test specs. Covers test spec configuration, app host requirements, and testing patterns that integrate with pod lib lint validation.

Use when working with Maven build phases, goals, profiles, or customizing the build process for Java projects.

Use when building reliable and scalable distributed systems.

Use when functional programming patterns in Scala including higher-order functions, immutability, pattern matching, algebraic data types, monads, for-comprehensions, and functional composition for building robust, type-safe applications.
