Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It does reveal what the tool returns (full Markdown and metadata), but it does not mention error behavior, permissions, or side effects. Since this is a read-only operation, the lack of mutation details is acceptable, but other aspects like not-found handling are undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
