Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It states it can search by message, author, or date, but does not clarify how the 'query' parameter is interpreted (e.g., does it accept regex, multiple terms, or date formats?). It also does not mention potential side effects (none expected) or pagination behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
