What problem does it solve? Starting a new Jac project by hand leads to wrong layouts, missing jac.toml sections, and mismatched entry points. This Skill guides you through the official jac create scaffolder so every new project starts with the correct structure for its kind. ## Core Features & Use Cases - Kind-aware scaffolding: Choose from 12 built-in project kinds (cli, service, web-app, desktop, mobile, native-binary, and more) so jac run does the natural action for your project type. - Template and variant support: Scaffold from local template directories, .jacpack archives, URLs, or the built-in jac-shadcn variant for production UI with 53 accessible primitives. - Post-scaffold checklist: Covers jac install, jac check verification, running with jac run or jac start --dev, and headless browser QA with jac browse. - Use Case: You want to build a full-stack web app in Jac. The Skill helps you pick between standard web-app and jac-shadcn, scaffold it safely without nesting inside an existing project, and verify it compiles before writing any code. ## Quick Start Ask the assistant to scaffold a new Jac web application named myapp using jac create and then verify it compiles.
