Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read-only search tool with two parameters, full schema coverage, and an output schema available, the description is largely complete. It explains what to search, in what language, and how to use the returned canonical paths. The only notable gap is lack of explicit guidance on how this tool compares to sibling search tools, though that is not essential for basic invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
