Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate this is not read-only, but the description adds no behavioral context. It doesn't disclose whether the tool blocks until completion, returns a run ID asynchronously, or requires the copy job to be in a certain state before running. Without an output schema, the agent is left guessing about the operation's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
