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 mentions retrieving '50 comments' (implying a limit or default behavior) and specifies 'profile post (activity)', but fails to address critical aspects like rate limits, authentication needs, error handling, or whether it's read-only. This leaves significant gaps in understanding the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
