Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter list tool, the description is adequate but not complete. It does not describe the shape of the returned list (e.g., session IDs, names, status) or how the results connect with related tools like iccap_session_select. Since there is no output schema, the description could have provided more context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
