Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's mutation nature and lack of annotations, output schema, or parameter descriptions, the description is insufficient for a complete understanding. It omits context about expected inputs, error cases, return values, and interaction with the scene. The two simple parameters might lower complexity slightly, but the missing behavioral and contextual details make this incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
