Overview

This skill handles both creating and editing canvas apps through a unified workflow. It syncs the current app state to detect whether the app has existing content, then routes accordingly:

• CREATE mode — the app is empty or has no meaningful content; a new app is generated from scratch using a preferences wizard and parallel screen builders.
• EDIT mode (simple) — the app has existing content and the requested changes are small; edits are applied inline without planning agents.
• EDIT mode (complex) — the app has existing content and the requested changes are substantial; a planner designs the changes and parallel screen builders execute them.
