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 fails to specify whether this operation is destructive to existing shapes, what the 'timeoutMs' parameter governs (operation timeout? connection timeout?), or what side effects occur. The 'Compatibility tool' label hints at legacy behavior but doesn't explain what that entails.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
