Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple (zero params), but there is no output schema, so the description should explain what information is returned for each table/view (e.g., names, schema, type). Without this, an agent cannot fully predict the tool's response, leaving a notable completeness gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
