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."
