Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description compensates by enumerating the major fields returned (description, install commands, auth requirements, sample tools, links, field notes). It does not mention error behaviors or response format, but for a simple single-parameter get tool, this is sufficiently complete for an agent to understand what to expect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
