Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description is minimally viable but lacks specifics about the returned ledger information (e.g., header, transactions, metadata). Without an output schema, more detail would improve completeness, but the essential purpose is clear.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
