SKILL.md

The "Golden Rule of Generics" states that type parameters should appear twice or more in a function signature. If a type parameter only appears once, it's not relating anything and is likely unnecessary. Unnecessary type parameters create a false sense of type safety and can make inference less successful.

This skill helps you identify and eliminate superfluous type parameters, resulting in cleaner, more maintainable code that TypeScript can infer more effectively.

Type parameters must appear twice or more to establish a relationship. If a type parameter only appears once, strongly reconsider if you need it.

Úselo al escribir funciones o tipos genéricos. Úselo al revisar firmas tipográficas. Úselo cuando un parámetro de tipo solo aparece una vez. Úselo cuando tenga la tentación de agregar genéricos para mayor "flexibilidad". Fuente: marius-townhouse/effective-typescript-skills.
