Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden, and it discloses only that the result arrives as a prompt pack with examples. It does not say whether output is static or generated from the optional query, whether anything is persisted, or what the agent should expect to receive back. The one behavioral detail given (deliverable format) is real value but far from sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
