Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of disclosure. It indicates a read operation, but it does not specify what the 'summary' includes (e.g., consensus, high/low, number of analysts) or how it might differ from get_analyst_estimates. This lack of behavioral context limits the agent's ability to predict the tool's output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
