Use when lINQ (Language Integrated Query) with query and method syntax, deferred execution, expression trees, and performance optimization.

Manage aesthetic templates - save visual systems from completed mockups as interpretable prose, apply to new plugins with adaptive layouts

Use when writing tests with Bun's built-in test runner. Covers test organization, assertions, mocking, and snapshot testing using Bun's fast test infrastructure.

Create aesthetic templates without first creating a plugin - capture visual design concepts through adaptive questioning. Use when you want to build a library of visual systems before plugin implementation.

Use when building responsive layouts and mobile-first designs with Tailwind CSS. Covers breakpoints, container queries, and responsive utilities.

Use when setting up Playwright test projects and organizing test suites with proper configuration and project structure.

Use when building terminal UIs with Ink component patterns for React-based CLI applications.

Use when configuring artifacts for inter-job data passing or caching for faster builds. Covers cache strategies and artifact management.

Use when working with modern C++ codebases requiring features from C++11 to C++23 including lambdas, move semantics, ranges, and concepts.

Use when C# nullable reference types, null safety patterns, and migration strategies. Use when ensuring null safety in C# code.

Use when working with SQLite databases in Bun. Covers Bun's built-in SQLite driver, database operations, prepared statements, and transactions with high performance.

Orchestrator for WebView UI mockup workflow - delegates design iteration to ui-design-agent and implementation scaffolding to ui-finalization-agent. Use when user mentions UI design, mockup, WebView interface, or requests 'design UI for [plugin]'.

Use when Go interfaces including interface design, duck typing, and composition patterns. Use when designing Go APIs and abstractions.

Use when designing GraphQL schemas with type system, SDL patterns, field design, pagination, directives, and versioning strategies for maintainable and scalable APIs.

Master FastAPI dependency injection for building modular, testable APIs. Use when creating reusable dependencies and services.

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 FastAPI async patterns for building high-performance APIs. Use when handling concurrent requests and async operations.
