antfu — Skills — getagentictools

What it does

Single responsibility: Each source file should have a clear, focused scope/purpose

Split large files: Break files when they become large or handle too many concerns

Type separation: Always separate types and interfaces into types.ts or types/.ts

Constants extraction: Move constants to a dedicated constants.ts file

Prefer isomorphic code: Write runtime-agnostic code that works in Node, browser, and workers whenever possible

Clear runtime indicators: When code is environment-specific, add a comment at the top of the file:

Explicit return types: Declare return types explicitly when possible
