Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 0 parameters, no annotations, and no output schema, the description is minimally adequate. It states the action and resource but lacks details on behavior, output format, or integration with siblings. For a simple list operation, this might suffice, but it doesn't provide enough context for optimal agent use without additional inference.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
