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 nested objects, no output schema), the description covers the essentials: action, resource, unique condition ('Operator-deploy only'), and return format. It could optionally mention potential error states or timeouts, but for a poll tool this is adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
