Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It states the tool 'shows progress', implying a read-only operation, but does not explicitly confirm it is non-destructive or describe the nature of the returned data (e.g., fields like status, progress percentage). It also doesn't mention polling behavior or potential delays. The description is not contradictory but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
