Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given a single parameter, an existing output schema, and annotations covering safety and idempotency, the description gives adequate invoking context: precondition, action, and retry behavior. It could be more explicit about what constitutes a valid external publication receipt, but the essential calling context is present.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
