Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
There is no output schema or annotations, so the description must convey return information. It lists three report components (coverage, gaps, suggestions) but does not explain their meanings, structure, or how to interpret them. For a health-report tool, this is insufficient for an agent to know what to expect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
