Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has only 2 parameters, no output schema, and annotations covering idempotency/safety, the description is quite complete. It covers the action, return payload, and identifier provenance. The only notable gap is the missing semantic meaning of project_id, but this is optional and does not block correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
