Question 1

How does this skill help with code refactoring?

Accepted Answer

It identifies common architectural issues like Feature Envy and violations of the nine rules of Object Calisthenics, providing specific refactoring steps to improve code structure.

Question 2

Why does this skill discourage code comments?

Accepted Answer

It follows the philosophy that comments are often a sign of unclear code; instead, it guides you to use intention-revealing names and small, focused functions so the code reads like prose.

Question 3

How does it handle Dependency Inversion?

Accepted Answer

The skill enforces a policy against direct instantiation (using 'new') inside methods, prompting you to inject dependencies through constructors to ensure your code is decoupled and testable.

Question 4

Does this skill work with TypeScript?

Accepted Answer

Yes, it includes specific guidelines for TypeScript, such as using Zod for runtime validation, avoiding 'any' or 'as' keywords, and using discriminated unions to make illegal states unrepresentable.

Question 5

What is the 'Fail-Fast' principle included in this skill?

Accepted Answer

Fail-Fast ensures that the system throws clear, contextual errors immediately when expected data is missing, rather than using silent fallbacks that can mask bugs and complicate debugging.
