Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds substantial context beyond the annotations: the override scope is per-instance-only, the first call returns a 'loop_mode_requires_confirm' disclosure, and the agent must retry with confirm_loop_mode=true. This is exactly the kind of behavioral disclosure the agent needs for a multi-step mutation flow. The annotation set (non-readonly, openWorld, non-idempotent) is already sensible and not contradicted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
