Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema (not shown but noted), the description is minimally adequate. However, it omits context about what constitutes a 'stage' (e.g., is it a name, ID, or object?) and potential edge cases. For a simple tool with one required param and output schema, this is borderline acceptable but not rich.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
