user-story-mapping

From README

Purpose Visualize the user journey by creating a hierarchical map that breaks down high-level activities into steps and tasks, organized left-to-right as a narrative flow. Use this to build shared understanding across product, design, and engineering, prioritize features based on user workflows, and identify gaps or opportunities in the user experience. This is not a backlog—it's a strategic artifact that shows how users accomplish their goals, which then informs what to build. Input Works best with: The product or user workflow being mapped. Also useful: The primary user, the end-to-end narrative as you understand it, existing backlog items to place, and release goals. Anything supplied with the invocation itself — text after the skill name, a pasted context dump, or an appended ARGUMENTS: line — counts as answers already given. Use it and skip whatever it covers; don't re-ask. Arriving empty-handed? That works too.
