Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple (one param, output schema exists), so the description covers the basics. However, the absence of usage guidance and limited behavioral detail (e.g., what happens if no relationships exist, whether it includes inherited allocations) leaves gaps for an agent to confidently invoke it. An output schema exists, so return format is not required, but the tool would benefit from a note about its relationship to get_relationships.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
