Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden of behavioral disclosure. It does not mention that this creates a side-effect (adding a persistent comment), whether notify_all triggers notifications to members, whether assignee sets a commenter assignment, or any authorization requirements. For a mutation tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
