Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description must carry the burden. It only says 'invalidate' but does not disclose side effects, prerequisites (e.g., existence of a rotated secret), or whether the action is reversible. For a destructive operation, more details are needed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
