Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
This is a simple tool with one parameter and no output schema, so complexity is low. However, the description lacks information about return values, search scope (e.g., does it search cell content or sheet metadata?), and any filtering behavior. Without annotations or an output schema, the description should provide more context to be fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
