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. It only says 'Get', implying a read operation, but does not clarify what kinds of styles are included (fill, text, effect, grid), whether library styles are returned, or what the response contains. This is minimal behavioral detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
