What problem does it solve?

This Skill helps prevent memory leaks, double frees, and ownership confusion in C++ by guiding the correct selection and usage of smart pointers and custom deleters across common code patterns.

Core Features & Use Cases

• Ownership guidance: Choose between sole ownership with std::unique_ptr, shared ownership with std::shared_ptr, and observer semantics with std::weak_ptr.
• Cycle detection and resolution: Identify shared_ptr cycles and recommend breaking them with weak_ptr or redesigning ownership.
• Interoperability and cleanup: Recommend make_unique and make_shared for safe allocation and advise on custom deleters for C APIs and resource wrappers.
• Practical examples: Patterns include heterogeneous collections using vector of std::unique_ptr<Base>, parent-child graphs with parent as weak_ptr, and using enable_shared_from_this when objects need shared_from_this.

Quick Start

Ask the skill to recommend the appropriate smart pointer for each class relationship, detect potential cycles, and suggest fixes including custom deleter designs when needed.
