Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations include readOnlyHint: false, indicating the tool is a write operation. The description 'Create issue' merely reiterates this without adding any new behavioral context such as required permissions, side effects, or reversibility. It does not contradict the annotations, but provides no extra value beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
