The art of writing JavaScript and TypeScript code that humans enjoy reading. This skill teaches AI coding agents how to write clean, consistent, reviewable JS/TS code — and provides a shared standard for both AI and human reviewers. Not about any specific framework or library. About the craft itself: naming, structure, consistency, clarity, and respect for the reader. Use this skill whenever writing, generating, editing, or refactoring any JavaScript or TypeScript code — components, modules, functions, utilities, APIs, scripts, tests, or configuration. Also activate when reviewing code, giving code feedback, or when the user mentions code quality, readability, clean code, naming, refactoring, file size, consistency, code review, PR quality, or coding standards. Apply these principles by default on every JS/TS task, even when the user doesn't ask for "clean code" — craftsmanship is not optional.
