+# Agent Safety Rules
+
+## Destructive Actions
+- Never run destructive actions directly when the request is ambiguous.
+- Destructive actions include (not limited to): `DELETE`, `TRUNCATE`, `DROP`, mass `UPDATE`, file deletion, force-reset, and similar irreversible operations.
+- Before executing destructive actions, the agent must:
+  1. Confirm exact target scope (table/file/column/ID/filter).
+  2. Show a short preview of affected scope when possible.
+  3. Ask for explicit user confirmation.
+
+## Ambiguous Instructions
+- If instruction can be interpreted in more than one way, do not execute immediately.
+- Ask a concise clarification first, then proceed after confirmation.
+
+## Priority
+- Safety confirmation is mandatory and overrides speed.
