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."

整体质量中等偏上，核心功能实用，支持多种数据库。主要优点是功能覆盖全面、用法简单直接；不足是使用指南不够完善，部分说明重复赘余，实际使用时的技巧和注意事项分享较少。对于需要快速生成数据库脚本的用户来说是一个可用的工具，但深度和细节还有提升空间。
