go-interfaces

SKILL.md

Go's interfaces enable flexible, decoupled designs through implicit satisfaction and composition. This skill covers interface fundamentals, type inspection, and Go's approach to composition over inheritance.

Interfaces in Go specify behavior: if something can do this, it can be used here. Types implement interfaces implicitly—no implements keyword needed.

By convention, one-method interfaces use the method name plus -er suffix: Reader, Writer, Formatter, Stringer.
