What it does

This skill teaches an AI agent to act as a senior C++ developer. Once installed, when you ask for C++ help, the agent follows modern C++ practices such as concepts, RAII, smart pointers, and const-correctness, and loads detailed reference notes on templates, memory and SIMD performance, concurrency, and CMake/sanitizer tooling. It is guidance for writing and reviewing code rather than a standalone tool.

Great for

  • Developers writing or refactoring C++20/23 code who want consistent modern idioms
  • Engineers chasing performance bottlenecks or concurrency bugs in C++ projects
  • Teams setting up or fixing CMake builds with sanitizers and warnings enabled

Skip it if

  • Non-C++ codebases, since the guidance is specific to C++ and related skills exist for Rust and embedded systems
  • Safety-critical production code without human review, because generated C++ can still contain memory or undefined-behaviour bugs that need compiler and sanitizer verification

Try asking

  • “Refactor this C++ class to use RAII and move semantics, and explain the design choices”
  • “Write a C++20 concept that constrains a container template to numeric types”
  • “Set up a CMakeLists.txt with -Wall -Wextra -Wpedantic and AddressSanitizer enabled”
  • “Find why this multithreaded C++ code has a data race and suggest a fix”

    Add it to your agent

    Claude Code (all projects)

    mkdir -p ~/.claude/skills && unzip cpp-pro.zip -d ~/.claude/skills/

    Claude Code / Agent SDK (this project only)

    mkdir -p .claude/skills && unzip cpp-pro.zip -d .claude/skills/

    Claude apps (web/desktop): Settings → Capabilities → Skills → Upload skill, and choose the ZIP.

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Provide your compiler, C++ standard version and build system up front so the agent targets the right features
  • Ask for the sanitizer and test steps explicitly and run them yourself, since the skill is guidance and does not execute code
  • Review generated concurrency and memory code carefully before merging
