Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, no annotations, and no behavioral details, the description fails to convey what the tool actually returns (e.g., form IDs, titles). For a tool with zero parameters and no structured output, the description should at least mention the kind of data returned, making the context incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
