Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the essential aspects: how to identify the proposal, version handling, choice semantics, update behavior, and encryption. It omits explicit instructions on obtaining the proposal id or option slugs, but these are implied from other tools. An output schema exists, so return format is not needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
