Practical overview

When it fits

Use it during database design, schema review or migration planning when you want Claude Code to reason across modeling, integrity, indexing, performance and migration safety.

Who it is for

  • Developers using Claude Code to plan a new database schema.
  • Teams reviewing existing schema files for integrity and performance concerns.
  • Developers comparing schema versions or checking migration files before changes.

Documented uses

  • Draft a database schema from a plain-language description.
  • Audit schema files and report separate Design & Integrity and Performance & Scale scores.
  • Explain a table, finding or query-related concern in plain language.
  • Lint a migration file or diff two schemas to plan a migration.
  • Preview proposed fixes and confirm changes individually.
Before you choose

Requirements & limits

The README documents Claude Code plugin installation and installation through Vercel Skills for other agent environments. Tier 0 is described as working offline without keys; live introspection is an opt-in higher-tier path. The repository is MIT-licensed.

  • Claude is the runtime; Node and Python helpers are described as optional.
  • Audits produce two independent 0–100 scores with letter bands and prioritized findings.
  • The README says findings include observed evidence and verification commands; checks requiring a live database are marked needs_api.
  • Audit, explain, score, next and checklist are described as read-only; fixes preview diffs and write only after confirmation.
  • Destructive migrations require typing the object name for confirmation.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
