Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is simple, the lack of annotations and output schema means the description alone must cover behavior, but it omits important contextual details such as return values, error handling, uniqueness requirements, and the broader workflow implications of creating and selecting a model. Given the sibling tools include get_model, delete_model, and edit_model, more context would help an agent choose and invoke this tool reliably.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
