Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only paginated history tool with an output schema, the description covers purpose, ordering, auth, return-value scope, the sibling tool for bodies, and the platform's diff limitation. Pagination details are already handled comprehensively in the schema, so nothing essential is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
