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 states that it lists campfires visible to the current user, but it does not disclose whether the operation is read-only, the return format, ordering, pagination, or any side effects. For a simple list operation, some mention of return value or safety would improve transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
