Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It states the action 'List' but does not mention pagination, ordering, or the limiting effect of maxResults, despite the description saying 'all'. The mismatch between 'all' and the maxResults parameter is a transparency concern, as the tool will not always return all tasks.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
