What problem does it solve?
This Skill prevents common errors in database interactions by ensuring that Claude is aware of and adheres to the project's database schema, preventing issues like incorrect column names, types, or relationships.
Core Features & Use Cases
- Schema Verification: Before writing database code, Claude reads and verifies against the schema file.
- Type Generation: Utilizes generated types (e.g., from Drizzle, Prisma, Supabase) for type-safe database queries.
- Error Prevention: Catches common mistakes like wrong column names, incorrect types, missing nullable checks, and incorrect relationships.
- Use Case: When implementing a new API endpoint that requires fetching user data, Claude will first read the
users table schema, verify the existence and types of columns like id, email, and name, and then use generated types to write a type-safe query, preventing runtime errors.
Quick Start
Use the database-schema skill to verify the schema for the 'users' and 'orders' tables before writing code to fetch order history for a user.
