Under the hood
This is what the agent actually calls when you ask for it — real tools from its live surface, not marketing copy.
extend_musicExtend an existing Suno-generated track with more music, continuing from (or near) a point in the source track. Use when the user wants a previously generated track made longer. Requires the source track's audioId (get it from get_generation_history / fetch_user_generations for a prior generate_music result).
