Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure but provides none. It doesn't indicate whether this tool executes commands, launches applications, analyzes files, or performs some other action. There's no mention of permissions required, whether it modifies files, what output to expect, or any behavioral characteristics. The description is essentially non-functional for behavioral understanding.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
