Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple toggle tool, the description covers the essential aspects: the action, scope (new conversations), verification method, and side effect. It does not mention what happens if the mode is already in the desired state or whether any permissions are required, but these are less critical given the tool's simplicity. Overall, it is sufficiently complete for an agent to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
