Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Although simple, the tool lacks context about the exact return value (e.g., URL string format, expiration), prerequisites, or how it differs from sibling attachment tools. With no output schema, the description should provide more detail, but it only offers a minimal phrase.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
