Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a creation tool with a nontrivial confirmation workflow, the description covers everything an agent needs: what to pass, what the first call returns, what the second call must contain, the permanent-URL consequence, and the next recommended tool (invite_member). The output schema exists and the input schema is fully documented, so no critical context is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
