What problem does it solve? Building Wix CLI app extensions requires choosing among a dozen extension types, coordinating CLI scaffolding, data collections, permissions, and validation — a process prone to misconfiguration and failed App Market reviews. ## Core Features & Use Cases - Extension Type Decision Logic: Routes requirements to the right extension type — dashboard pages, modals, plugins, custom element widgets, Editor React components, service plugins, backend events, backend APIs, and data collections. - CLI-Driven Scaffolding: Uses wix generate --params for all supported extension types, then fills in business logic guided by per-extension reference files. - Auto-Patterns CRUD Pages: Generates declarative patterns.json dashboard pages for single-collection CRUD admin interfaces via a bundled generator script. - Validation & App Market Readiness: Runs a four-step validation workflow (install, TypeScript, build, preview) and audits apps against the App Market review checklist. - Use Case: Ask to build a dashboard page that manages fee rules stored in a data collection, with a service plugin that reads those rules at checkout — the skill scaffolds all extensions, coordinates collection IDs, and validates the build. ## Quick Start Ask the assistant to build a Wix app extension, for example: create a dashboard page to manage product recommendations stored in a data collection.
