What problem does it solve? When a user wants to add a mobile app, slide deck, or any second app alongside an existing project, the project must first be restructured to support multiple artifacts. This Skill orchestrates that migration without breaking the existing app. ## Core Features & Use Cases - Migration Proposal Workflow: Creates plan files under .local/tasks/ and calls proposeMigration with a port task plus optional follow-up tasks. - Canonical Port Plans: Provides ready-to-copy port rubrics for fullstack_js and Expo projects, plus a template for follow-up task plans (mobile apps, slides, video, auth). - Verification Scripts: Includes shell scripts that detect project structure, copy backend/frontend files, fix imports (zod/v4, @workspace/db), and run post-migration sanity checks. - Use Case: A user with an existing restaurant website asks for a mobile companion app. The Skill ports the website into a pnpm workspace, then guides building an Expo app that reuses the same brand assets, colors, and fonts. ## Quick Start Ask the assistant to migrate the project to multi-artifact support so a mobile app can be added alongside the existing app.
