Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (5 parameters with nested objects, 0% schema coverage, no annotations, no output schema), the description is completely inadequate. It doesn't explain the tool's behavior, parameter usage, output, or differentiation from siblings, leaving the agent with insufficient information to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
