Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, yet it only hints that the output is a prompt plus playbook. It does not say what is actually returned, whether the bundled prompt is applied or merely displayed, how the optional query alters behavior, or any limits. The claims 'save hours' and 'battle-tested' are marketing assertions rather than behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
