Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Rename a pane for easier identification' states the core action but does not mention potential side effects, error conditions, required permissions, or whether the name change is temporary or persistent. For a mutation tool, this is a noticeable gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
