Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description reveals the async nature of the operation ('async generation pipeline'), which is a behavioral trait not captured in the annotations (openWorldHint=false, destructiveHint=false). However, it does not disclose other important behaviors such as required permissions, whether existing documents are replaced, or how results are delivered. With minimal annotations, the description only partially fulfills the transparency burden.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
