What masterdata-storage-strategy does

The skill establishes architectural rules for VTEX storage. It evaluates whether a workload belongs in Master Data or requires Catalog, OMS, VBase, or an external database. Master Data cannot sustain sub-10ms response times, so placing it in checkout or payment critical paths will hurt conversion rates.

Guidance covers VTEX-specific schema extensions, including v-indexed, v-cache, v-default-fields, and v-security. Only query filter fields belong in v-indexed. Every secondary index forces updates on every write, driving up latency and consuming storage.

Implementation code for VTEX IO clients is out of scope here; other repository skills handle client integration.

What it helps with

  • select between Master Data, VBase, Catalog, and external SQL storage
  • configure JSON schemas using v-indexed and v-security
  • determine caching behavior via v-cache for high-write entities
  • audit existing entity schemas to remove unnecessary secondary indexes

Example prompts for the agent

  • Evaluate whether Master Data or VBase is better for storing user session flags
  • Design a JSON Schema with v-indexed and v-security for a product wishlist entity
  • Check if my schema indexes too many fields for write-heavy workloads

How do I install masterdata-storage-strategy in Claude Code?

Run npx skills add vtex/skills --skill masterdata-storage-strategy -a claude-code. The skill file will be placed at ~/.claude/skills/masterdata-storage-strategy/SKILL.md.

What does this skill help with?

It guides schema design and storage choices in VTEX, preventing over-indexing and misuse of Master Data for checkout-critical flows.

When should you avoid VTEX Master Data?

Avoid Master Data for relational data requiring joins, high-throughput time-series records, or checkout paths where sub-10ms latency is mandatory.
