cpp skillA
cpp is agent-read markdown (skill) from jnpiyush/agentx: Write modern, maintainable C++ using C++23-era practices. Use when building native libraries, performance-sensitive services, desktop applications, game/engine components, or systems software that benefits from RAII, strong types, templates, and zero-cost abstractions..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# C++ Development > WHEN: Writing or reviewing modern C++ for native libraries, back-end services, desktop apps, game/engine code, or high-performance systems where RAII, value semantics, and type safety matter. ## When to Use This Skill - Building modern C++ libraries and executables - Refactoring legacy pointer-heavy C++ toward safer ownership - Designing ABI-conscious native interfaces - Applying templates, ranges, spans, and concurrency utilities responsibly - Hardening performance-sensitive code without sacrificing maintainability ## Decision Tree ``` C++ Project Decision +-- New codebase? | +-- General application/library? -> C++23 default | +-- ABI-constrained or older platform? -> C++20 minimum with explicit constraints +-- Ownership model? | +-- Single owner? -> std::unique_ptr / value types | +-- Shared ownership truly required? -> std::shared_ptr sparingly +-- API design? | +-- Read-only view? -> std::string_view / std::span<const T> | +-- Mutable buffer view? -> std::span<T> +-- Error handling? | +-- Exceptions allowed? -> throw only across layers that can preserve invariants | +-- Exceptions forbidden? -> std::expected or status/result type …

How to install
mdr add jnpiyush/agentx/cpp@v1.0.0mdr add jnpiyush/agentx/cpp@sha256:09d3f1f0010ce706Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
