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 does disclose the return type (embeddable markdown), but it does not mention any side effects, authentication requirements, file type restrictions, overwriting behavior, or other operational details that would be expected for an upload/mutation tool. This is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
