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. 'List' implies a read-only operation scoped to a specific issue, but it does not mention pagination, ordering, error behavior, or whether the issue must exist. This is adequate for a simple list operation but lacks richer behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
