Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavioral traits. It states the operation but does not clarify pagination behavior (the presence of max/first parameters suggests it may not return 'all' in one page), nor does it mention search filtering, read-only nature, or any response format. This is insufficient for a tool with no annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
