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. While 'Deletes a task' conveys the basic destructive nature, it does not mention permanence, cascading effects, error behavior for non-existent tasks, or any permissions needed. This is a significant gap for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
