Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, 0% schema coverage, no output schema, and a retrieval tool with 1 parameter (though complex nested structure), the description is incomplete. It doesn't explain the array-based input format, what happens when multiple projects are requested, error handling, or return format, leaving significant gaps for agent understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
