What specific patterns does it recommend for error handling?

It promotes the Result type pattern and discriminated unions over throwing exceptions, ensuring errors are handled explicitly within the type system.

How does this skill improve TypeScript code quality?

It enforces strict type-safety patterns and modern error-handling strategies that catch potential bugs at compile-time rather than runtime.

Can it help with refactoring existing codebases?

Yes, the skill provides specific guidelines for refactoring legacy code to meet modern standards, such as replacing 'any' types with type guards.

Does it provide a recommended tsconfig setup?

Yes, it includes a 'maximum strictness' tsconfig template that enables features like noUncheckedIndexedAccess and exactOptionalPropertyTypes.
