Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states that the tool resets to auto-fit all data, implying it overrides manual zoom/pan, but it does not disclose potential side effects such as whether it affects other chart states (e.g., indicators, drawings, multiple panes) or if it is destructive. More detail would be needed for full transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
