Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has two parameters, no annotations, and no output schema, the description is minimally viable but incomplete. It explains the core action but omits crucial context such as what happens when resending (e.g., new notification sent), any state restrictions, or what the response contains. This falls short for a mutation tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
