What problem does it solve?
Guides UX software engineering—translating user flows into interaction specs and coded prototypes, performing heuristic UX reviews, organizing information architecture in product, shaping micro-interactions, and enabling design-engineering handoff. It bridges discovery output and production UI. Use when prototyping flows in code, specifying interaction behavior for engineering, auditing UX in a live or staging app, fixing confusing flows, or defining states and edge cases for builders—not for research-only discovery (product-designer), pixel-perfect production implementation from final Figma (ui-software-engineer), senior FE performance/architecture (senior-frontend-software-engineer), or BRDs (business-analyst).
Core Features & Use Cases
- Translate user journeys into flow diagrams and interaction specs for engineering.
- Build clickable or coded prototypes to validate flows before production.
- Perform heuristic UX audits and convert findings into actionable tickets.
- Define interaction details: validation timing, focus management, undo, confirmations.
- Improve information architecture and support UX handoff with clear acceptance criteria.
Quick Start
Describe a user flow you want to prototype and I will generate an interaction spec and prototype outline.
