Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a file operation with no annotations, no output schema, and 0% parameter coverage, the description is incomplete. An agent needs to know whether destination is a directory or full path, whether overwrite is allowed, and what the return value indicates. The sibling set includes move_multiple, copy, and rename, so more context is needed to select and invoke this tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
