Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple polling tool this is minimally viable: it names the core identifier, the action, and the terminal states, and the schema supplies the platform enum. However, with no output schema and no annotations, it does not explain the response payload, polling behavior details, or failure semantics, so it is not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
