Wix Cli App Validation

If you're building Wix apps with their CLI, this skill automates the validation workflow before you ship. It runs through a four-step checklist: detects your package manager (npm, yarn, or pnpm based on lockfiles), installs dependencies, checks TypeScript compilation, builds, and previews. The sequential approach is smart because it stops at the first failure rather than wasting time on downstream steps. It's the kind of thing you'd normally script yourself or forget to run consistently, so having it packaged as a skill saves you from "works on my machine" surprises when you deploy to Wix's platform.
