A DELETE or UPDATE statement without a WHERE clause applies to every row in the table instead of the intended one.
This is exactly the class of action that’s cheap to prevent and expensive to undo — rollback, insurance, and observability all kick in after the damage is done. The only place to stop it is a check that runs before the action does.
DELETE FROM users; wipes the entire users table instead of a single row.
Black_Wall raises SQL_NO_WHERE and stops the query before it runs.
Black_Wall returns a risk score (0–100), a reversibility class, this named red flag, and a gate — proceed / confirm / human-required — in a few seconds, before the action runs.
Paste an action your agent might take and watch Black_Wall gate it — no signup.
