Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite low complexity (3 params, no output schema), the description provides insufficient context. It omits what the tool returns, how 'fields' and 'include' work, and any prerequisite conditions. For a retrieval tool, the agent needs more to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
