Docker 2025 Features

This covers Docker's 2025 feature set, which is actually substantial: image type mounts let you mount layers directly without extraction, Enhanced Container Isolation adds a security boundary that blocks socket escapes, and the Model Runner lets you run LLMs locally via llama.cpp. It includes BuildKit cache recipes, Docker AI assistant usage, and Compose v2 watch mode examples. The skill proactively activates for questions about these newer capabilities, which is helpful since most Docker documentation still focuses on pre-2025 features. Good for teams running Engine 28+ or Desktop 4.38+ who want to use the latest security and performance improvements without digging through release notes.

Files

🚨 CRITICAL GUIDELINES

Windows File Path Requirements

MANDATORY: Always Use Backslashes on Windows for File Paths

When using Edit or Write tools on Windows, you MUST use backslashes (\) in file paths, NOT forward slashes (/).

Examples:

❌ WRONG: D:/repos/project/file.tsx
✅ CORRECT: D:\repos\project\file.tsx

This applies to:

Edit tool file_path parameter
Write tool file_path parameter
All file operations on Windows systems

Documentation Guidelines

NEVER create new documentation files unless explicitly requested by the user.

Priority: Update existing README.md files rather than creating new documentation
Repository cleanliness: Keep repository root clean - only README.md unless user requests otherwise
Style: Documentation should be concise, direct, and professional - avoid AI-generated tone
User preference: Only create additional .md files when user specifically asks for documentation
