How does the safety verification process work?

Before generating any files, the skill executes a mandatory 'Theory of Mind' checkpoint. It presents a summary of its understanding and asks for confirmation to ensure no unintended data loss occurs.

Does it automatically create rollback scripts?

Yes. For every migration generated, the skill creates corresponding 'down' logic (such as dropping a table or column) to ensure your database can be safely reverted to a previous state.

Which database frameworks does this skill support?

The skill natively supports Prisma, Knex, TypeORM, Drizzle, and raw SQL. It automatically detects which framework your project is using by scanning your configuration files.

Can it handle complex changes like adding NOT NULL columns to existing tables?

Yes, the skill includes safety checks that warn you if you're adding a NOT NULL column without a default value, which would normally fail on tables that already contain data.

Database Management

Automates the creation of safe database migrations with automatic framework detection and built-in rollback logic.

This skill simplifies database schema evolution by automatically detecting your project's migration framework—supporting Knex, Prisma, TypeORM, Drizzle, and raw SQL. It guides users through creating new tables, modifying columns, and adding indexes while enforcing a critical verification checkpoint to ensure the AI understands the schema requirements before any changes are generated. By ensuring every 'up' migration has a corresponding 'down' migration and performing safety checks for destructive operations like dropping columns, it significantly reduces the risk of data loss and schema inconsistencies.
