## What it does

This skill guides the architecture of VTEX IO storefront theme packages. A theme app relies on declarative JSON rather than React components. It arranges pages using files inside `store/`, such as `store/blocks.json` and `store/routes.json`. Omitting the `store` builder in `manifest.json` causes the platform to ignore every block layout completely.

The instructions enforce correct block references across native templates like `store.home` and `store.product`. Every block identifier must resolve to an installed dependency with matching major version bounds, preventing runtime `Missing block` failures in GraphQL. The skill also separates concerns: React code stays in component packages, while the theme app controls layout hierarchies and `store/contentSchemas.json`.

## When to use it
- compose block hierarchies for native pages like store.product
- define custom storefront routing inside store/routes.json
- extend a base theme like vtex.store-theme via manifest.json
- prevent missing block errors by matching dependency major versions

## Example prompts
- Inspect store/blocks.json to verify all block IDs match our dependencies
- Add a custom storefront route bound to store.custom in store/routes.json
- Set up the block layout for store.search using flex-layout.row
