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 only provides the cryptic '(Compatibility tool)' hint without explaining side effects, return format, or why this is considered a compatibility tool. No mention of what the presets contain 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.
