Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with no annotations, 0% schema coverage, no output schema, and a nested object parameter, the description is completely inadequate. It fails to explain what configuration backup settings are, how to structure the 'body' parameter, what the tool returns, or any side effects, making it insufficient for safe and correct use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
