Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It only says 'Get active/pending orders,' implying a read-only operation but does not disclose any further behavioral details such as pagination, response structure, or how the optional symbol filter behaves. The agent is left with minimal transparency beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
