Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'List all draft schedules' but does not mention pagination behavior, although the schema includes limit/offset with a max limit of 100, so 'all' is potentially misleading. There is no mention of ordering, read-only nature, or any side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
