Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full disclosure burden and fails it: nothing is said about whether the tool reads or writes, whether it executes SQL or only generates a formula, what permissions or costs are involved, or what happens on failure. "Includes the complete prompt, usage guide, and edge-case handling" describes packaged content, not runtime behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
