Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple delete operation with annotations and an output schema, the description covers the essential information: action, resource, identifier, and auth requirement. It could mention irreversibility, but destructiveHint already covers that. The tool is well-specified for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
