WHY IT NEEDS A POLICY

Why crear_items needs a policy

This tool creates new inventory items in MongoDB. Creation is a reversible write operation (items can be deleted afterward), so it falls under Write rather than Destructive. Misuse could pollute the inventory with spurious records, hence medium severity.

From the tool's definition "Crear uno o más items en el inventario" — creates one or more items in the inventory

crear_items Rate-limited

crear_items stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
