Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of a destructive operation, no annotations, and 0% schema description coverage, the description is insufficient. While an output schema exists, the description doesn't address behavioral risks, prerequisites, or sibling tool distinctions, making it incomplete for safe and effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
