Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full burden of behavioral disclosure. It reveals nothing about what the tool actually does: no mention of sorting logic, ordering of results, whether the input is a pasted document, permissions, or output shape. Instead it advertises a "battle-tested prompt," which tells an agent nothing about 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.
