Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (batch mutation tool), no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It lacks crucial context like response format, error handling, permissions, and detailed parameter guidance. For a tool that modifies multiple resources, this is inadequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
