Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a batch creation tool with no annotations, 0% schema description coverage, no output schema, and complex nested parameters, the description is insufficient. It doesn't address behavioral expectations, parameter meanings, error handling, or differentiation from sibling tools, leaving significant gaps for an AI agent to understand proper usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
