Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (a destructive mutation tool), no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It lacks information on behavioral traits (e.g., irreversibility, side effects), output format, error conditions, and usage context. For a tool that permanently modifies data, this minimal description is inadequate to ensure safe and correct usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
