Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 parameters, no output schema, no nested objects) and the presence of annotations, the description covers the basic functionality. However, it does not explain the effect (e.g., link becomes invalid, returns success) or any required context like needing the user ID. It is minimally acceptable but could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
