Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no annotations, no output schema, and a simple input schema, the description is insufficiently complete. It lacks details on behavioral traits (e.g., read-only nature, data format), usage context compared to siblings, and any limitations or prerequisites, making it inadequate for an agent to fully understand how to invoke and interpret results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
