Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of annotations, 0% schema description coverage, no output schema, and multiple sibling tools, the description is insufficient. It doesn't explain parameters, return values, behavioral constraints, or differentiation from alternatives, leaving the agent with inadequate context for proper tool selection and invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
