Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (1 parameter, no output schema, no nested objects), the description covers the key behavioral aspects: what it does, preconditions (completed, provisioned), and deployment context. It does not mention error messages or what exactly 'degrades to info' means, but for this complexity level it is largely sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
