Ultrathink
Use /ultrathink <TASK_DESCRIPTION> to launch a Coordinator Agent that directs four specialist sub-agents—Architect, Research, Coder, and Tester—to analyze, design, implement, and validate your coding task. The process breaks the task into clear steps, gathers insights, and synthesizes a cohesive solution with actionable outputs. Relevant files can be referenced ad-hoc using @ filename syntax.
