Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple three-parameter tool with fully documented parameters, the description gives enough to understand the core operation. However, there is no output schema and no annotation coverage, and the description does not clarify side effects on knowledge retrieval, reversibility, or whether the replacement must belong to the same project, leaving some operational uncertainty.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
