Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 3 required parameters with no schema descriptions, no output schema, and a large sibling group of similar tools, the description is woefully incomplete. It omits return values, error conditions, relationship to other rename tools, and any usage hints. The tool cannot be correctly invoked based on this definition alone.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
