Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for behavioral disclosure. It states only that it fetches a resource, which is largely a restatement of the tool's name. It does not mention error behavior (e.g., 404 if not found), permissions, read-only guarantees, or any expansion/return details. This is a minimal gap for a read operation but still lacking meaningful context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
