Core Workflow Analyze architecture — Review build system, compiler flags, performance requirements Design with concepts — Create type-safe interfaces using C++20 concepts Implement zero-cost — Apply RAII, constexpr, and zero-overhead abstractions Verify quality — Run sanitizers and static analysis; if AddressSanitizer or UndefinedBehaviorSanitizer report issues, fix all memory and UB errors before proceeding Benchmark — Profile with real workloads; if performance targets are not met, apply targeted optimizations (SIMD, cache layout, move semantics) and re-measure Reference Guide Load detailed guidance based on context: Topic Reference Load When Modern C++ Features references/modern-cpp.md C++20/23 features, concepts, ranges, coroutines Template Metaprogramming references/templates.md Variadic templates, SFINAE, type traits, CRTP Memory & Performance references/memory-performance.md Allocators, SIMD, cache optimization, move semantics Concurrency references/concurrency.md Atomics, lock-free structures, thread pools, coroutines Build & Tooling references/build-tooling.md CMake, sanitizers, static analysis, testing Constraints MUST DO Follow C++ Core Guidelines Use concepts for template constraints Apply RAII universally Use auto with type deduction Prefer std::unique_ptr and std::shared_ptr Enable all compiler warnings (-Wall -Wextra -Wpedantic) Run AddressSanitizer and UndefinedBehaviorSanitizer Write const-correct code MUST NOT DO Use raw new / delete (prefer smart pointers) Ignore compiler warnings Use C-style casts (use static_cast, etc.) Mix exception and error code patterns inconsistently Write non-const-correct code Use using namespace std in headers Ignore undefined behavior Skip move semantics for expensive types Key Patterns Concept Definition (C++20) // Define a reusable, self-documenting constraint template < typename T> concept Numeric = std::integral<T> || std::floating_point<T>; template <Numeric T> T clamp (T value, T lo, T hi) { return std:: clamp (value, lo, hi); } RAII Resource Wrapper // Wraps a raw handle; no manual cleanup needed at call sites class FileHandle { public : explicit FileHandle ( const char * path) : handle_(std::fopen(path, \"r\" )) { if (!handle_) throw std:: runtime_error ( \"Cannot open file\" ); } ~ FileHandle () { if (handle_) std:: fclose (handle_); } // Non-copyable, movable FileHandle ( const FileHandle&) = delete ; FileHandle& operator =( const FileHandle&) = delete ; FileHandle (FileHandle&& other) noexcept : handle_ (std:: exchange (other.handle_, nullptr )) {} std::FILE* get () const noexcept { return handle_; } private : std::FILE* handle_; }; Smart Pointer Ownership // Prefer make_unique / make_shared; avoid raw new/delete auto buffer = std::make_unique<std::array<std::byte, 4096 >>(); // Shared ownership only when genuinely needed auto config = std:: make_shared <Config>( parseArgs (argc, argv)); Output Templates When implementing C++ features, provide: Header file with interfaces and templates Implementation file (when needed) CMakeLists.txt updates (if applicable) Test file demonstrating usage Brief explanation of design decisions and performance characteristics Documentation",
