Node.js Best Practices skill: what it does and how to install it

What it does. Guides Node.js decisions by comparing frameworks and runtimes, choosing module systems, and applying layered architecture. It covers async and event-loop patterns, boundary validation, centralised errors, security checklists and test strategy.

When to use it. Use for Node.js architecture, framework selection, async design, security and deployment planning. It is not a substitute for environment-specific validation, testing or expert review, and asks for clarification when requirements are missing.
