Umbraco Quickstart

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.

Workflow

1. Parse arguments

First argument: Umbraco project name (e.g., "MyUmbracoSite")
Second argument: Extension name (e.g., "MyExtension")
--email (optional): Admin email (default: admin@test.com)
--password (optional): Admin password (default: SecurePass1234)

If arguments not provided, check what exists and prompt for missing names.

2. Check what exists

Version guard (run first): Before building anything, invoke umbraco-version-guard to confirm the site's Umbraco major matches the major these skills target. On a mismatch,
