Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a one-parameter read-style analytics tool, the description is mostly adequate: it states the resource, the batch limit, and the error behavior. However, with no annotations and no output schema, it leaves the agent without information about the response format, whether the operation is read-only, or how per-post errors are represented. The sibling get_post_analytics exists, so a brief contrast would have improved completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
