Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter, no-output-schema tool, the description fully covers what the tool does and when to use it. It specifies the topic (Solomon's help contracts/quests), the subtopics (kinds, rewards/escrow, verification), and the trigger question type. There is no missing context that would confuse an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
