Use when building reusable component patterns with Tailwind CSS. Covers component extraction, @apply directive, and composable design patterns.

Use when scala's advanced type system including generics, variance, type bounds, implicit conversions, type classes, higher-kinded types, path-dependent types, and abstract type members for building type-safe, flexible APIs.

This skill should be used when running .NET tests selectively with a build-first, test-targeted workflow. Use it for running tests with xUnit focus.

This skill should be used for Python scripting and Gemini image generation. Use when users ask to generate images, create AI art, edit images with AI, or run Python scripts with uv. Trigger phrases include "generate an image", "create a picture", "draw", "make an image of", "nano banana", or any image generation request.

Use when domain-specific language design in Kotlin using type-safe builders, infix functions, operator overloading, lambdas with receivers, and patterns for creating expressive, readable DSLs for configuration and domain modeling.

Use when next.js App Router with layouts, loading states, and streaming. Use when building modern Next.js 13+ applications.

Build and train neural networks with TensorFlow

Use when designing modules and components requiring Composition Over Inheritance, Law of Demeter, Tell Don't Ask, and Encapsulation principles that transcend programming paradigms.

This skill should be used when planning and tracking complex feature implementations that require systematic task decomposition. Use this skill to break down large features into manageable, well-documented tasks with clear dependencies, action items, and success criteria. The skill provides a structured template and methodology for iterative planning and tracking throughout implementation.

Use when configuring Credo static analysis for Elixir projects requiring customized code quality rules and settings.

Use when Elixir Ecto patterns including schemas, changesets, queries, and transactions. Use when building database-driven Elixir applications.

Use when implementing polymorphism and interfaces in object-oriented design. Use when creating flexible, extensible systems with interchangeable components.

Use when designing solutions, adding features, or refactoring by applying KISS, YAGNI, and Principle of Least Astonishment to write simple, predictable code.

Use when demonstrating plugin workflow features - shows how skills can guide multi-step processes

Orchestrates JUCE plugin implementation through stages 1-3 (Foundation, DSP, GUI) using subagent delegation with automatic validation after each stage. Use when implementing plugins after planning completes, or when resuming with /continue command. Invoked by /implement command.

Use when optimizing React Native app performance. Covers FlatList optimization, memoization, image optimization, bundle size reduction, and profiling techniques.

Use when working with React Native Web projects. Provides core concepts, components, and cross-platform patterns for building web applications with React Native.

Use when configuring Expo apps with app.json, app.config.js, and EAS configuration. Covers app metadata, plugins, build configuration, and environment variables.
