Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full behavioral burden. It discloses that the tool lists products and returns specific fields, which is useful. However, it does not mention authorization requirements, side effects, or whether the store must exist, leaving some gaps for a tool with no annotation safety net.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
