Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that an output schema exists and annotations provide safety context, the description covers core purpose and use cases. However, it omits overwrite behavior, which is a minor gap for a write tool with idempotent hint. Still, it is largely complete for its complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
