Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden and does not meet it. "Includes the complete prompt, usage guide, and edge-case handling" is the only hint about what comes back, and it is phrased as a package-content claim rather than a description of the response; nothing is said about output shape, whether the query changes the result, or whether the tool is a read or a generation step.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
