Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden, yet only the verb "Delete" implies destructiveness — information already in the name. It says nothing about irreversibility, required permissions, or side effects on related images, stock, or documents that reference the product.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
