Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has 0 parameters and no output schema; however, it is one of a very long list of sibling tools (set_time_position, set_sequence_settings, set_frame_blend, etc.) that share the 'set_*' prefix. The description gives no basis for an agent to understand in which workflow to choose this tool, because it does not mention timeline, selected clips, keyframes, or interpolation type. There may be hidden prerequisites (for example, active sequence), and the missing output schema means no return value is described.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
