Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no parameters, no output schema, and low complexity, the description is largely complete. A minor gap is that 'currently available' is not defined precisely (e.g., whether it refers to a completed calculation, loaded results, or something else), but the overall context is sufficient for a status check.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
