Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the weight of behavioral disclosure. It explicitly states what the tool returns ('business overview, financial snapshot, and recent catalysts') and that no payment is required. This adds meaningful context about the operation and its accessibility, though it does not cover rate limits, data freshness, or any potential side effects. It is transparent enough for a read-oriented tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
