What problem does it solve? Teams often spend weeks debating product ideas without structured validation. This Skill guides the first three days of a Jake Knapp design sprint, turning open-ended problems into a mapped customer journey, eight divergent sketches, and a Decider-approved storyboard ready for prototyping. ## Core Features & Use Cases - Monday Mapping: Set a Long-Term Goal, invert risks into 3 Sprint Questions, and draw a 5-15 step Customer Journey Map on tldraw or Markdown. - Tuesday Divergence: Run Lightning Demos with Stitch MCP and generate eight labeled Crazy 8s variations using the Pencil.dev headless pen CLI. - Wednesday Decision: Execute the Sticky Decision Funnel (Heatmap voting, Speed Critique, Decider Supervote) and produce a 10-15 panel storyboard with .stitch/DESIGN.md tokens. - Use Case: A product team redesigning a checkout flow uses this Skill to map the journey, generate eight Pencil.dev concepts for the payment step, and hand a locked storyboard to the Thursday prototype build. ## Quick Start Run a design sprint for our onboarding flow: set the long-term goal, write 3 sprint questions, map the journey, and produce a 12-panel storyboard.
