Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It states 'Create' implying a write operation, but lacks disclosure of side effects, authentication needs, rate limits, or behavior like overwriting existing schedules. The 'allowalteration' parameter hints at a safety mechanism, but its significance is not explained in the description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
