What problem does it solve? Product teams lack an artifact between user journeys and wireframes that shows where users go and what the system does without dropping into detailed UI design. This Skill generates verified wireflow diagrams (SVG/HTML) from a compact JSON board spec, keeping Jobs-To-Be-Done at the core, and can also critique an existing wireflow against a structured review rubric. ## Core Features & Use Cases - Spec-driven diagram generation: Write a board.json of journeys, lanes, nodes, and edges, then render per-journey horizontal SVGs or a shared owner-by-journey matrix, plus a combined HTML with legend and JTBD × Journey coverage matrix. - Self-verifying build pipeline: Rasterize output to PNG (via cairosvg, rsvg-convert, resvg, or headless Chrome) and Read the images to catch overlaps, out-of-lane nodes, and glyph problems before delivery. - Create or review modes: Build new wireflows from journeys, JTBDs, specs, or live prototypes, or score an existing wireflow against 11 review criteria and return a structured verdict with fixes. - Use Case: During a product definition phase, derive journey set and spine decisions from a PRD and job register, generate a wireflow where every screen node links to a live route, then hand off to page-level specification. ## Quick Start Ask the agent to create a wireflow from your user journeys and JTBDs, generating verified SVG and HTML diagrams in the briefs output directory.
