Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the input schema, output schema, and annotations, the description is mostly complete for correct invocation: it states the domain, the static nature, the limitation, and pricing. A slight gap is the lack of guidance on how 'files' content should be structured and how ecosystem selection works, but these are partially inferable from the schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
