cpp SKILL.md skillA
cpp from jnpiyush/agentx is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jnpiyush/agentx/cpp@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:09d3f1f0010ce706The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
