Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description does not explain what information is returned for each table (e.g., table ID, name, metadata). It is a simple listing, but the lack of return format, pagination, or error behavior leaves notable gaps, making it only moderately complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
