+# C++ Best Practices Skill
+
+## Overview
+Modern C++ programming best practices for high-performance Windows development.
+
+## Key Principles
+
+### RAII (Resource Acquisition Is Initialization)
+```cpp
+class FileHandle {
+    HANDLE handle_;
+public:
+    FileHandle(const wchar_t* path) {
+        handle_ = CreateFileW(path, ...);
+    }
+    ~FileHandle() {
+        if (handle_ != INVALID_HANDLE_VALUE) {
+            CloseHandle(handle_);
+        }
+    }
+    // Disable copying, enable moving
+    FileHandle(const FileHandle&) = delete;
+    FileHandle(FileHandle&& other) noexcept
+        : handle_(other.handle_) {
+        other.handle_ = INVALID_HANDLE_VALUE;
+    }
+};
+```
+
+### Smart Pointers
+- Use `std::unique_ptr` for exclusive ownership
+- Use `std::shared_ptr` sparingly
+- Avoid `std::weak_ptr` unless breaking cycles
+
+### Modern C++ Features
+- Range-based for loops
+- Auto type deduction
+- Lambda expressions
+- Structured bindings (C++17)
+- Concepts (C++20)
+
+## Performance Tips
+1. Avoid unnecessary copying (use std::move)
+2. Reserve container capacity
+3. Use string_view for read-only strings
+4. Inline hot functions
+5. Profile before optimizing
