What problem does it solve? When starting a new Jac project, it is unclear which build commands, runtimes, and documentation guides apply to your specific project type. This Skill routes you from your project kind to the correct verbs and guides immediately. ## Core Features & Use Cases - Project Kind Routing: Covers eleven project kinds including CLI tools, API services, microservices, full-stack apps, native binaries, shared libraries, wasm, desktop, mobile, and PyPI/npm packages. - Kind-Aware Tooling: Explains how jac create --kind <kind> scaffolds projects and how a bare jac run resolves the right action (execute, serve, or build) from jac.toml. - Guide Loading Map: Each kind lists exactly which jac guide <name> documents to load, plus cross-cutting guides for testing, debugging, LLM functions, and deployment. - Use Case: You want to ship a pip-installable CLI written in Jac. The routing table tells you to run jac build --as wheel, then twine upload dist/*, and to load jac-packaging and jac-impl-files first. ## Quick Start Ask the assistant to identify which Jac project kind fits your idea and list the build commands and guides to load for it.
