Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a destructive, open-world mutation, it covers irreversibility, cascading side effects, sibling alternatives, confirmation requirements, and error behavior (404 for unknown ID). An output schema exists, yet the description still notes the return shape, so nothing needed to call it safely is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
