Write idiomatic Ruby code with metaprogramming, Rails patterns, and performance optimization. Specializes in Ruby on Rails, gem development, and testing frameworks. Use PROACTIVELY for Ruby refactoring, optimization, or complex Ruby features.
Ruby programming with blocks, metaprogramming, gems, and Rails conventions. Use for .rb files.
Julia: multiple dispatch, type system, metaprogramming, Pkg, scientific computing, GPU CUDA.jl
Use when building C++ applications requiring modern C++20/23 features, template metaprogramming, or high-performance systems. Invoke for concepts, ranges, coroutines, SIMD optimization, memory management.
Comprehensive Zig 0.15.2 development expert. Use when writing Zig code, debugging memory issues, designing build systems, implementing comptime metaprogramming, handling errors, or cross-compiling. Automatically activated for any .zig file or build.zig work.
Zig comptime skill for compile-time evaluation and metaprogramming. Use when using comptime parameters, comptime types, generics via anytype, comptime reflection with @typeInfo, or metaprogramming patterns that replace C++ templates. Activates on queries about Zig comptime, compile-time evaluation, Zig generics, anytype, @typeInfo, comptime types, or Zig metaprogramming.
C++ template skill for reading template errors and optimizing compile times. Use when deciphering template error stacks, setting -ftemplate-backtrace-limit, writing concepts and requires-clauses, understanding SFINAE vs concepts, or profiling template instantiation bottlenecks with Templight. Activates on queries about C++ templates, template error messages, concepts, requires expressions, SFINAE, template metaprogramming, or slow template compilation.
Comprehensive Ruby development skill covering language fundamentals, object-oriented design patterns, error handling strategies, performance optimization, modern Ruby 3.x features (pattern matching, ractors, typed Ruby), testing patterns, metaprogramming, concurrency, and Rails-specific best practices. Use when writing Ruby code, refactoring, implementing design patterns, handling exceptions, optimizing performance, writing tests, or applying Ruby idioms and conventions.
Up-to-date Zig programming language patterns for version 0.15.x. Use when writing, reviewing, or debugging Zig code, working with build.zig and build.zig.zon files, or using comptime metaprogramming. Critical for avoiding outdated patterns from training data - especially build system APIs (root_module instead of root_source_file), I/O APIs (buffered writer pattern), container initialization (.empty/.init), allocator selection (DebugAllocator), and removed language features (async/await, usingnamespace).
Use when working with Ruby metaprogramming features including dynamic method definition, method_missing, class_eval, define_method, and reflection.
Use when implementing compile-time metaprogramming in Crystal using macros for code generation, DSLs, compile-time computation, and abstract syntax tree manipulation.
Expert-level Ruby development with Rails, modern features, testing, and best practices
