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 mentions the output type (heatmap) and purpose (prediction), but fails to detail critical traits such as data sources, update frequency, accuracy limitations, or the '$0.05' cost implication. This leaves significant gaps in understanding the tool's behavior and constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
