`check_naming`	Validate C++ identifiers (variables, classes, functions, etc.) against naming conventions
`check_include_guard`	Verify header file include guards or `#pragma once` usage
`analyze_memory_safety`	Detect memory leaks, dangling pointers, and unsafe memory patterns
`suggest_modern_cpp`	Get modernization suggestions targeting C++11 through C++23
`check_const_correctness`	Find missing `const` qualifiers on member functions, parameters, and variables

Resources

URI	Description
`cpp-style://naming/{category}`	Naming convention reference (variable, class, function, namespace, …)
`cpp-style://best-practices/{topic}`	Best practice guides (memory, exceptions, templates, concurrency, …)
`cpp-style://standard/{version}`	C++ standard feature docs (cpp11 – cpp23)
`cpp-style://examples/{pattern}`	Design pattern examples (RAII, Pimpl, Factory, Observer, …)

Prompts
