How does this skill improve code quality?

It enforces strict syntax, explicit type conversions, and modern module patterns to reduce runtime bugs and improve codebase readability.

Can I use this for existing projects?

Absolutely. It is ideal for reviewing existing code, refactoring legacy modules, or establishing a baseline for new project architecture.

What runtime APIs does it prioritize?

The skill encourages modern standards like globalThis over window and import.meta.dirname for reliable directory path handling.

Does it support TypeScript specific features?

Yes, it provides specific conventions for TypeScript, including explicit .ts extensions, type-safe comparisons, and preferred type casting methods.
