Code smell detector for Ruby

Design, implement, and review Kotlin and Android APIs. Use when working on .kt files, Kotlin nullability, sealed classes/interfaces, coroutines, Android threading, Java interop, or Kotlin-backed React Native Nitro Module implementations.

Design, implement, and review modern C++ APIs and native implementation code. Use when working on .cpp, .hpp, CMake, RAII ownership, std::variant, callbacks, async work, platform bridges, or C++-backed React Native Nitro Module implementations.

Audit a repository for architectural decay, AI-generated code smells, stale compatibility paths, dead abstractions, boundary violations, and cleanup candidates without modifying files. Use when the user asks to review code quality, find bad code, inspect AI-generated code, identify refactoring or cleanup opportunities, detect legacy leftovers, or produce a cleanup backlog that requires human confirmation before implementation.

16-dimension test suite audit with depth control (quick/standard/deep), gap matrix, and health scoring. Covers coverage, quality, mocking, data management, CI/CD, performance, mutation testing, and modern patterns. Use when evaluating test suite quality, identifying testing gaps, or assessing test infrastructure health.

Use when generating, planning, authoring, or recording an Epic Web / Epic React style workshop, exercise, tip, or video. Applies Kent C. Dodds' "How to be an Epic Instructor" principles to workshop design, exercise structure, recording, and material delivery, and encodes Epic Web's exercise-comment emoji conventions. Used to generate workshops following https://www.epicweb.dev/get-started. Triggers on "create a workshop", "generate a workshop", "design an exercise", "record a workshop video", "Epic workshop", "Epic Web", "Epic React", or `/epic-workshop`.
