Use when styling React Native + Expo components: choosing between StyleSheet/NativeWind/inline, wiring NativeWind v4 from DESIGN.md tokens, handling Flexbox in RN (column-by-default, not row), safe-area insets, dark mode, responsive design with useWindowDimensions, optimized images via expo-image, performant lists via FlashList. Triggers on: "style this screen", "add dark mode", "fix safe area", "import design tokens", "set up NativeWind", or when an agent is about to write StyleSheet/className in an RN file. Not for: building screens end-to-end (rn-add-screen, Wave 2), navigation (rn-expo-router), animations (rn-animations-gestures, Wave 3), or web styling (Next.js stack).

rn-styling — guardrail for styling in React Native + Expo

The 5 rules (non-negotiable)

NativeWind v4 is the default. StyleSheet only for performance-critical paths (per-frame animations etc.).
No magic numbers. Every spacing/color/radius/font value comes from tailwind.config.js (which mirrors the project's DESIGN.md tokens).
SafeArea mandatory on every root screen. Use SafeAreaView from react-native-safe-area-context (NOT the one from react-native).
Dark mode via useColorScheme + Tailwind dark: variant. Never Appearance.getColorScheme() at module top-level.
Optimized primitives: expo-image instead of Image; @shopify/flash-list for any list > 20 items.

Quick decision tree

"Should I style this with NativeWind or StyleSheet?" → references/decision-tree.md
"How do I set up NativeWind v4 from scratch?" → references/nativewind-setup.md
"Why does Flexbox behave differently than on the web?" → references/concepts.md
"What are the common patterns and anti-patterns?" → references/patterns.md
"Show me a real example" → references/examples/

Common anti-patterns (NEVER do)

❌ style={{ padding: 16 }} with a magic number — pull from token.
❌ Root <View> without SafeAreaView from react-native-safe-area-context.
❌ import "tailwindcss" directly in code — only NativeWind imports.
❌ Appearance.getColorScheme() at module level — use useColorScheme() hook.
❌ Image from react-native for remote URIs — use expo-image.
❌ flex: 1 on root + scroll without contentContainerStyle on ScrollView — content gets clipped.

design-md-to-app

lukedj78/dev-flow

Generate or customize a frontend application from a DESIGN.md (Google design.md spec). Reads the YAML tokens + markdown rationale and produces a working React app whose theme, typography, spacing, radii, and components are pre-styled to match. **Canonical target: Next.js 16 + App Router** (Pages Router or pre-16 explicitly refused). Supports three UI libraries: shadcn/ui (Tailwind + copy-pasted source), Base UI (Tailwind + headless library, no CLI overhead), and MUI (runtime themed, Material-flavored). Supports two form libraries: **TanStack Form + Zod (default, recommended)** or react-hook-form (opt-in). Integrates with the dev-flow contract: when a `.workflow/` exists, reads `meta.json#stack`, writes the app at the project root (alongside `.workflow/`), and bumps phase to `scaffolded`. Use whenever the user has a DESIGN.md and wants to scaffold an app, set up a theme, customize shadcn/Base UI/MUI from these tokens, or "use this DESIGN.md to start an app". Trigger on "DESIGN.md → app", "scaffold from design.

module-add

lukedj78/dev-flow

Wire a backend or infrastructure module (auth, database, payments, email, file storage, deploy config) into an already-scaffolded app. Reads `.workflow/meta.json#stack` for the chosen tech (better-auth, drizzle+neon, stripe, resend, vercel, etc.) and modifies the codebase at the project root to install + configure the module end-to-end. Always idempotent — running twice does not duplicate config. Use when the user says "add auth", "wire up the database", "set up Stripe", "add file uploads", "configure deploy", "module aggiungi auth", or the orchestrator routes here from phase `scaffolded` / `page_generated`. Not for: scaffolding the app (`design-md-to-app`) or building UI (`screenshot-to-page`).

eve-agent

lukedj78/dev-flow

Scaffold and manage an eve agent (Vercel's filesystem-first agent framework) inside a monorepo, as the engine behind a Next.js app. Use this skill whenever the user wants to create, set up, or initialize an eve agent; add a tool, skill, channel, connection, schedule, subagent, or hook to an eve agent; wire a Next.js (or any) frontend to consume an eve agent; or evolve the `apps/agent` part of a project. Trigger this for ANY mention of "eve", "the agent engine", "agent tools", "agent backend", or building the agentic core of an app — even if the user does not say the word "skill". This is the eve counterpart to dev-flow's Next.js skills (design-md-to-app / module-add); use it for the agent the same way you'd use those for the web app. Not for: building the Next.js app itself or its pages/forms (use design-md-to-app / screenshot-to-page / module-add), scaffolding the monorepo (use monorepo-bootstrap), or React Native (eve is a server-side engine, not an RN concern).

screenshot-to-page

lukedj78/dev-flow

Generate a real, working page (route + components) inside an already-scaffolded app from a single UI screenshot, applying the project's DESIGN.md tokens and the existing UI library (shadcn or MUI). Reads a screenshot from `.workflow/screenshots/`, plus `.workflow/DESIGN.md` and `.workflow/meta.json` for tokens and stack, then writes the route into the codebase at the project root. Use when the user says "fai questa pagina dallo screenshot", "build the home page from this image", "/journal route from this PNG", "convert this mockup to code", or the orchestrator routes here from phase `scaffolded` with unmapped screenshots present. Not for: scaffolding the app from scratch (use `design-md-to-app`), extracting tokens from Figma (use `figma-to-design-md`), or wiring backend modules (use `module-add`).

monorepo-bootstrap

lukedj78/dev-flow

Scaffold a turborepo monorepo containing both a Next.js web app AND an Expo + RN mobile app, with shared packages (types, design tokens, backend client). Uses pnpm workspaces + turborepo. Reads .workflow/meta.json with stack.framework="monorepo" and phase in {prd_drafted, design_extracted}. Produces: root package.json + pnpm-workspace.yaml + turbo.json + packages/typescript-config + packages/eslint-config; apps/web/ scaffolded via design-md-to-app; apps/mobile/ scaffolded via rn-bootstrap; packages/shared/ + packages/design/ + packages/api/ skeletons. Always idempotent. Use when dev-flow routes here from prd_drafted+monorepo, or the user says "scaffolda il monorepo", "create a turborepo with web + mobile", "bootstrap il monorepo da PRD + DESIGN.md". Not for: scaffolding only web (use design-md-to-app), scaffolding only mobile (use rn-bootstrap), adding modules after scaffold (use module-add or rn-module-add).

dev-flow

lukedj78/dev-flow

Orchestrate an end-to-end product-development workflow built on atomic skills. Reads `.workflow/meta.json` in a project directory, figures out what phase the user is in (idea → PRD → tasks → design → scaffolded → pages → modules → tests), and delegates to the right specialist skill: `prd-from-idea`, `prd-to-tasks`, `figma-to-design-md`, `image-to-design-md`, `design-md-to-app`, `screenshot-to-page`, `module-add`, `write-tests`, `forms`, `data-fetching`, `state-discipline`, `eve-agent` (the eve agent engine behind the app). Use when the user wants to "start a new project end-to-end", "advance my project to the next stage", "what should I do next on this project", or pastes a brand-new product idea / Figma URL / inspiration images with a request to "build the app". Not for: deeply-specialized work inside one stage (in that case, invoke the specialist skill directly).
