Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full disclosure burden. It states the operation is 'Irreversible,' which is the single most important behavioral trait for a destructive tool, and it scopes the action to the user's own posts. It does not mention error conditions, permissions, or side effects, but the critical permanence warning is present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
