What vtex-io-data-access-patterns does

This skill guides decisions on where data belongs across VTEX IO apps. It directs assistants to keep merchant toggles and base endpoints inside app settings. Storing arrays or operational state in settingsSchema is forbidden. Operational entities belong in Master Data or VBase instead.

VTEX platform APIs must remain the primary source of truth for orders and pricing. Local copies must stay strictly limited to lightweight derived attributes. Large reads must rely on database pagination and targeted field selection. Filtering full collections inside Node memory is blocked.

The rules do not cover granular Master Data schema modeling, auth tokens, or runtime sizing.

What it helps with

  • pick between VBase, Master Data, and app settings
  • remove operational transaction arrays from settingsSchema
  • replace in-memory collection filtering with paginated database queries
  • build lean cache representations without cloning core commerce models

Example prompts for the agent

  • Review this VTEX IO service to ensure operational data is not stored in app settings
  • Decide whether we should use VBase or Master Data for storing temporary customer export snapshots
  • Refactor this Master Data query to use server-side pagination instead of loading everything into memory
