Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema present, return-value details need not be restated, and all parameters are schema-documented, so the description only needs to convey purpose and caveats – which it largely does, including the commitment-payment warning. The main gap is routing guidance among the many pricing siblings (buy_vs_rent, estimate_cost, gpu_prices), which remains absent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
