# Migration lock-safety checker

> Paste migration SQL and see which lock each statement takes and whether a new table ships without RLS.

Paste an ALTER TABLE, CREATE INDEX or CREATE POLICY statement. The SQL is sent to the public lint endpoint (POST https://api.scribase.com/v1/public/migration-lint, no signup, body {"sql": "..."}) and the response lists each finding with its line, rule and severity (BLOCK or WARN). The SQL is linted only; it is not stored or run against a database.
