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 mentions a timeout parameter with a default value, which is useful context about potential delays. However, it doesn't describe what the search returns (web results, AI responses, documents), authentication requirements, rate limits, error conditions, or any other behavioral characteristics. For a search tool with no annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
