Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple, but with no output schema, the description should at least hint at what 'metadata' includes or what happens on failure (e.g., 'returns file size, type, owner'). The current description leaves the agent guessing about the return payload and error behavior, making it incomplete for reliable tool invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
