Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of an output schema, the description gives a reasonable overview (list of subscriptions, event types, active state, no signing secrets). However, it does not mention whether the response includes IDs, URLs, or other fields, and does not clarify ordering or result structure. Middle-of-the-road completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
