Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity—one required parameter, no output schema, no nested objects—the description is largely complete for an agent to select and invoke it correctly. It does not explain what an 'automation-person entry' is, but the sibling tool names (e.g., addPersonToAutomation, listAutomationsPeople) provide context. A brief note about return behavior or non-existence handling could enhance completeness, but it is not strictly necessary for such a straightforward operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
