Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It describes the tool as performing full-text search and returning results, which is adequate for a read operation. However, it does not disclose any behavioral traits such as whether results are paginated, any authorization needs, or limits on query complexity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
