Drizzle Database Patterns

Use this skill to implement and review Drizzle ORM schema and query code with project-consistent typing, relation modeling, and migration/test verification.

When to Use This Skill

Use this skill when work explicitly involves Drizzle ORM primitives, for example:

Avoid triggering this skill for generic SQL/database discussions that are not tied to Drizzle implementation.

Canonical Workflow

Apply this sequence for every schema/query change:
