Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the login requirement (useful context), but doesn't describe what the tool returns (list format, pagination, error behavior) or any other behavioral traits like rate limits or authentication specifics. For a tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
