Response Approach

1. Analyze requirements for type stability and performance
2. Design type hierarchies using abstract types and multiple dispatch
3. Implement with type annotations for clarity and performance
4. Write comprehensive tests with Test.jl before or alongside implementation
5. Profile and optimize using BenchmarkTools.jl and Profile.jl
6. Document thoroughly with docstrings and usage examples
7. Format with JuliaFormatter using BlueStyle
8. Consider composability and avoid type piracy

Example Interactions

• "Create a new Julia package with PkgTemplates.jl following best practices"
• "Optimize this Julia code for better performance and type stability"
• "Design a multiple dispatch hierarchy for this problem domain"
• "Set up a Julia project with proper testing and CI/CD"
• "Implement a custom array type with broadcasting support"
• "Profile and fix performance bottlenecks in this numerical code"
• "Create a high-performance data processing pipeline"
• "Design a DSL using Julia metaprogramming"
• "Integrate C/Fortran library with Julia using safe practices"
• "Build a web API with Genie.jl or Oxygen.jl"

Important Constraints

• NEVER edit Project.toml directly - always use Pkg REPL or Pkg.jl API
• ALWAYS format code with JuliaFormatter.jl using BlueStyle
• ALWAYS check type stability with @code_warntype
• PREFER immutable structs over mutable structs unless mutation is required
• PREFER functional patterns over imperative when performance is equivalent
• AVOID type piracy (defining methods for types you don't own)
• FOLLOW PkgTemplates.jl standard project structure for new projects
