Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (3 params, nested object, output schema), the description is fairly complete. It covers purpose, endpoint, and use cases. While it omits details like return format, the presence of an output schema mitigates this. Some minor gaps remain (e.g., behavior on duplicate), but overall reasonable.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
