High-quality C++ OOP coding style (archibate / parallel101 lineage) that overrides sloppy AI-default C++. Use this skill WHENEVER writing, editing, refactoring, or reviewing C++ code (.cpp / .h / .hpp / .cc / .cxx), designing C++ classes, interfaces, APIs, or libraries, or when the user mentions C++ design, OOP, design patterns, dependency injection, RAII, or "clean / modern C++". Also use it for CMake-based C++ project setup, module targets, usage requirements, third-party dependency…
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
# archibate C++ OOP Style A skill that makes you write C++ the way a senior systems engineer who loves design patterns writes it — not the way an autocompleter does. When this skill is loaded, it **overrides** your default C++ instincts. ## The one rule > **"Abstract class, data class, or value type. Nothing else."** Every type you introduce is one of these three kinds — never the muddy middle: - **Abstract class** — *behavior only*. A pure-virtual interface with no data members of its own; any injected collaborators live in its concrete `…Impl`, not in the interface. Always has `virtual ~T() = default;`. This is the unit of *polymorphism and dependency injection*. - **Data class** — *data only*. A plain `struct` with public fields, built with designated initializers. No business logic, no getters/setters wrapping plain fields. This is the unit of *value passing and configuration*. - **Value / resource type** — a concrete, value-semantic type that either owns a resource (an RAII wrapper) or enforces one invariant (a strong type: `Money`, `EmailAddress`, a math `Vector3`, a C-handle wrapper). It has a small, total …

How to install
mdr add archibate/agent-skills/cpp-oop-style@sha256:2f5340d62ffc451dThe line at the top of this page pins the label git:20261004.16d6d0a, 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.
