Use the Supabase connection to read the current schema, row level security flags, policies, indexes and table sizes of the linked project; do not run the migration and do not write to the project. Post one GitHub review that flags tables without row level security, policies that grant more than the app needs or skip the project's MFA check, grants such as truncate to anon, migrations that take long locks on large tables, SECURITY DEFINER functions without a fixed search_path, and foreign keys without an index, each with file and line.
