Stop Cursor from running drizzle-kit push --force on a real database
Here is the failure mode. You change a Drizzle schema and ask the Cursor agent to sync the database. It runs npx drizzle-kit push . The command stops on a prompt, or errors because there is no terminal to prompt in. The agent retries with npx drizzle-kit push --force . It finishes. A table you cared about is now empty, or a renamed column lost its data. This post covers what push and --force…
Drizzle-kit's push command applies schema changes directly to the database, without creating migration files. When changing a schema, push runs a safety check that flags statements which could lose data, such as dropping a table or column, changing a column's type, or adding a NOT NULL column without a default value. If any statements are flagged, push prompts the user to confirm they still want to push the changes, providing a safety net against accidental data loss.
However, when running the push command in non-interactive environments, such as continuous integration pipelines, the prompt library refuses to run and throws an error. To address this, there are several guardrails that can be implemented. First, a rule can be created to stop the agent from running any drizzle-kit command that could potentially cause data loss, including "drizzle-kit push --force", without asking the user.
Additionally, if push stops on a prompt or a TTY error, the agent should not add the "--force" flag and should instead quote the prompt to the user, offering three options: using "drizzle-kit generate" to see the new SQL file, waiting for approval before running "drizzle-kit migrate", or using "drizzle-kit generate --explain" to view the planned SQL without applying it.
This approach ensures that destructive statements are visible in review and allows the user to make an informed decision before proceeding.
