Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple nature of the tool (single parameter, no output schema), the description adequately covers what the tool returns (topic details including intent and trigger phrases). It could be more comprehensive about potential additional fields, but the combination with annotations is sufficient for a basic read operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
