Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with no annotations, no output schema, and 0% schema description coverage, the description is completely inadequate. It doesn't explain what defensive synergies means, how they're calculated, what the output format is, or provide any meaningful context for the single parameter. The language mismatch further reduces completeness for English-speaking agents.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
