Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple delete operation with a single parameter and an output schema present, the description covers the essential prerequisites (document_id source), ownership requirement, scope, and irreversibility. It does not explain error cases or the response format, but the output schema likely covers that. The completeness is strong but not exhaustive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
