What problem does it solve? Teams with a finished PRD often struggle to decide which screen to build first and how to structure its UI. This Skill reads the PRD, filters user stories down to the single highest-value one, maps it to one of seven proven AI-app UI patterns, and writes a GUIDELINE.md that an AI coding agent can build from directly. ## Core Features & Use Cases - Valuable-story filtering: Applies three gates (core loop, visible AI hand-off, meaningful failure mode) to cut admin CRUD and low-value stories out of the PRD. - Pattern mapping: Maps the surviving story to one of 7 UI patterns (chat + panel, upload dashboard, query-to-chart, wizard, draft-approve-send, queue, real-time streaming) using a decision table. - GUIDELINE.md generation: Writes a single repo-root file containing the pattern choice, visual style, 3-step user flow, T·C·R (Transparency, Control, Recovery) checklist, and an LLM hinge rule. - Use Case: A hackathon team pastes their PRD for an AI syllabus builder; the Skill picks the wizard + inline audit pattern and writes GUIDELINE.md so Claude Code can plan and build the baseline screen. ## Quick Start Paste your PRD or give its file path and ask which screen to build first.
