Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no parameters, no output schema, no annotations, and a highly complex environment (Premiere Pro), the description is grossly incomplete. It should at minimum state what kind of data is returned (list of workspace names?), whether the tool is safe to call anytime, and any prerequisites like verifying a connection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
