Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema present, the description covers the core aspects: what the quote is, what it returns (amount and chains), and its non-payment nature. The sibling tool set clarifies the payment flow. Minor gap: no explicit mention of quote expiry duration, but that is a detail likely covered by the output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
