Is the migration process safe for production databases?

While the skill generates scripts with transaction safety to prevent data corruption, it is a best practice to backup your database and validate scripts in a staging environment before production deployment.

What kind of schema differences can it detect?

It identifies differences in tables, columns, data types, indexes, foreign key constraints, and database triggers.

Does it provide a way to undo changes?

Yes, every migration script generated by the skill includes a corresponding rollback procedure to safely revert changes if an error occurs.

Which database engines are supported by this skill?

The Database Diff Tool skill currently supports PostgreSQL and MySQL for schema comparisons and migration generation.
