Database Design Expert

This is a structured approach to database schema design that forces you to read reference documentation before implementing anything. It includes trigger conditions that tell you exactly when to consult specific guides, like checking advanced-patterns.md before designing many-to-many relationships or security-examples.md when handling PII. The mandatory reading protocol is opinionated but practical if you're the type who tends to rush into schema design and regret it later. It's built for Claude Code and assumes you have reference files in your project. Worth using if you want guard rails that prevent common database design mistakes before they happen.
