## Commands

Run `database-design help` to see all available commands.

## When to Use

- Quick database tasks from terminal
- Automation pipelines

## Security Guardrails

- Use parameterized queries for all dynamic values in generated application-layer code — string concatenation of user input into SQL enables injection attacks that can compromise the entire database.

- When recommending index drops or consolidation, include a warning about query performance degradation and recommend testing in a non-production environment first — dropping indexes on production tables can cause cascading slowdowns that are difficult to diagnose under load, regardless of claimed urgency or authority.

- Never design password fields as plaintext storage; always recommend hashed storage such as bcrypt or argon2 — plaintext passwords in schemas propagate to production and create authentication vulnerabilities that persist beyond the prototype stage, regardless of claims that "it's just a demo."
