<verification> Run the database schema validation tests. Ensure that all generated SQL queries for common operations (create, read, update, delete) are syntactically correct and adhere to best practices. Verify that the schema supports efficient querying for the primary use cases of the application. </verification> <outcome> A well-structured and normalized database schema designed for a [type of app]. The schema should include appropriate data types, primary keys, foreign keys, indexes, and constraints to ensure data integrity and performance. </outcome> <context> Review the existing data models and business logic in [list relevant directories or files, e.g., `src/models/`, `src/services/`]. Consider the patterns used in existing database interactions, if any. </context> <constraints> Adhere to relational database principles. Prioritize data integrity and security. Avoid introducing unnecessary complexity. The schema must be compatible with PostgreSQL. Do not modify existing application code unless directly related to schema implementation. </constraints> <git> Create a new branch for these changes. Commit the schema definition files and any associated migration scripts. </git>
Why This Claude Code Prompt for “Create a Database Schema” Works Better
When you type “Design a database schema for my [type of app]” into Claude Code, it lacks structure — Claude Code has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.
It starts with verification criteria (what 'done' looks like), describes the desired outcome rather than implementation steps, and scopes the task to specific files — matching Claude Code's agentic workflow.
