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 states the ranking action but lacks details on permissions, rate limits, output format, or whether it's a read-only operation. For a tool with two parameters and no annotation coverage, this is insufficient for safe and effective use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
