This is the full orchestra version of Umbraco setup. It creates your CMS instance, scaffolds an extension project, wires them together, then immediately drops you into planning mode where you sketch out what you're building with ASCII wireframes before writing any code. The workflow is opinionated: plan, build, validate with automated code review, then either fire up browser automation or give you manual testing steps. It'll nag you if the CMS or UUI source repos aren't in your workspace, which matters for better code generation. Best for when you're starting fresh and want guardrails instead of just a blank template. Takes you from nothing to a built, reviewed, running extension with one command and a conversation about what you want to make.
