Build native desktop apps in Go using Gova's declarative, component-based GUI framework with reactive state and platform-native integrations.
Deliver cross-platform and native mobile experiences across React Native, Flutter, SwiftUI, and Jetpack Compose without collapsing mobile work into a single framework.
This skill should be used when the user wants to build an "MCP app", add "interactive UI" or "widgets" to an MCP server, "render components in chat", build "MCP UI resources", make a tool that shows a "form", "picker", "dashboard" or "confirmation dialog" inline in the conversation, or mentions "apps SDK" in the context of MCP. Use AFTER the build-mcp-server skill has settled the deployment model, or when the user already knows they want UI widgets.
End-to-end XRPL development playbook. Covers XRP Ledger dApp development including project scaffolding (create-xrp), wallet integration (xrpl-connect), client SDKs, transactions, tokens, NFTs, DEX/AMM, cross-chain interoperability (Axelar), and security best practices.
You are **Mobile App Builder**, a specialized mobile application developer with expertise in native iOS/Android development and cross-platform frameworks. You create high-performance, user-friendly...
Guided journey from a raw app idea to a validated, cleanly architected first version that ships on a sustainable cadence. Orchestrates ten skills phase by phase - lean-startup, design-sprint, clean-architecture, domain-driven-design, clean-code, pragmatic-programmer, system-design, ios-hig-design, 37signals-way, software-design-philosophy - asking the user questions at every decision point and recording results in the project docs/ folder (PRODUCT.md, ARCHITECTURE.md, EXPERIMENTS.md, CREATE-APP-PLAN.md) so the journey resumes across sessions. Use when the user wants to build a new app, validate an idea before writing code, architect an MVP that will not need a rewrite, or says 'help me build my app the right way'. App already exists: use improve-app or grow-app. Business idea not yet validated: run create-business first. Marketing site only: use create-website. Architecture-only question: design-code-architecture. For one framework in isolation, invoke that skill directly.
Start here for any iOS or SwiftUI task. Coordinates best-practice guides, correctness checks, and full Apple API references. Use before navigating to other Apple skills — for building, reviewing, refactoring, or debugging iOS apps.
Use when building, modifying, or reviewing a Stripe App — or when the user describes something that implies one (e.g. "add a panel to the customer page", "customize my Stripe Dashboard", "react to Stripe events from my app", "connect my service to Stripe without sharing API keys"). Covers the full app development workflow (scaffold, preview, upload, versioning), UI extension architecture (sandboxed iframe, Stripe UI toolkit, viewports), extension types (UI extensions, backend-only, extension interfaces, embedded apps), authentication (platform keys, OAuth, restricted API keys), stripe-app.yaml manifest setup (permissions, viewports, CSP), webhook configuration for apps, Secret Store API, `fetchStripeSignature` auth, and marketplace publishing. Use when the user mentions Stripe Apps, UI extensions, @stripe/ui-extension-sdk, stripe-app.yaml, Dashboard extensions, or customizing the Stripe Dashboard.
Build native-feeling, benchmark-quality mobile app screens (Expo / React Native). Use when designing or implementing any mobile UI — screens, flows, onboarding, paywalls, tab bars, settings, empty states — or when polishing motion, typography, dark mode, or perceived performance. Enforces Apple HIG fidelity, semantic colors, native controls, purposeful Reanimated motion, a simulator-verified iteration loop, and a study-real-apps-first workflow (pairs with the Appllama MCP). Trigger on "build a screen", "make this screen better", "design the onboarding", "polish the UI", "make it feel native", or any mobile design/implementation task.
Reviews React Native TV apps for focus/D-pad navigation, 10-foot UI layout, TV playback/DRM integration, low-memory TV performance, and TV accessibility. Use when building, debugging, or reviewing react-native-tvos, Expo TV, Amazon Vega/Kepler, or React Native web TV targets where the issue depends on remote input, TV focus, TV packaging, TV hardware, or TV playback constraints.
Provide technical guidance for Android camera development with CameraX. Use when implementing camera features, handling asynchronous recording lifecycles, wiring low-level hardware interop using CameraX, or integrating ML Kit or Media3 effects.
Reference implementations for Factorial Code — a complete marketplace payroll integration (outbound sync with file-export and API-push delivery flavors), a multi-process custom app lifecycle (multi-step setup form, webhook + schedule install, polling, uninstall), and utility processes (CSV export with signed URL + email, XML enrichment from an uploaded file). Use when building a Factorial Code (fcode) integration, custom app, or automation end to end and you want a proven, working pattern to adapt — read the matching reference before writing code.
