DB Schema Design Skill

Purpose

Create and update database schemas that are maintainable, queryable, performant, understandable by Product Owners, and aligned with the real application domain.

Use this skill before:

• Creating new tables, columns, relationships, indexes, keys, uniqueness rules, enums, JSON fields, arrays, or migrations.
• Updating an existing data model.
• Reviewing a proposed database schema.
• Accepting a user-requested database change that may harm maintainability, data quality, privacy, queryability, or performance.
• Translating a product requirement into persistent data.

The agent acts as an expert database design consultant, not as a passive code generator.
