Agent skill

react-project-scaffolder

Use PROACTIVELY when creating new React projects requiring modern tooling and best practices. Provides three modes - sandbox (Vite + React for quick experiments), enterprise (Next.js with testing and CI/CD), and mobile (Expo + React Native). Enforces TypeScript strict mode, Testing Trophy approach, and 80% coverage. Not for non-React projects or modifying existing applications.

React Project Scaffolder

Overview

This skill automates the creation of React projects with three distinct modes tailored to different use cases. Each mode provides a complete, production-ready project structure with modern tooling and best practices.

Three Modes:

  1. Sandbox - Vite + React + TypeScript (~15s setup)
  2. Enterprise - Next.js + Testing + CI/CD (~60s setup)
  3. Mobile - Expo + React Native (~60s setup)

All modes follow Connor's standards: TypeScript strict mode, Testing Trophy approach, 80% coverage, conventional commits.

When to Use This Skill

Trigger Phrases:

  • "create a React project"
  • "scaffold a new React app"
  • "set up a React sandbox"
  • "create an enterprise React project"
  • "build a mobile React app"

Use Cases:

  • Quick React experiments without framework overhead
  • Enterprise web applications with industry-standard tooling
  • Cross-platform mobile apps with React Native
  • Establishing consistent project structure across teams

NOT for:

  • Non-React projects (Vue, Angular, Svelte)
  • Backend-only projects
  • Modifying existing React projects
  • Ejected Expo projects (bare workflow)

Response Style

  • Efficient: Minimize questions, maximize automation
  • Guided: Clear mode selection with pros/cons
  • Standards-driven: Apply Connor's standards automatically
  • Transparent: Explain what's being set up and why

Mode Selection

User Request Mode Framework Time
"quick React test" Sandbox Vite ~15s
"React sandbox" Sandbox Vite ~15s
"production React app" Enterprise Next.js ~60s
"enterprise React" Enterprise Next.js ~60s
"mobile app" Mobile Expo ~60s
"React Native project" Mobile Expo ~60s

Mode Overview

Sandbox Mode

Lightning-fast Vite + React + TypeScript for quick experiments. → Details: modes/sandbox.md

Enterprise Mode

Production-ready Next.js with testing, linting, and CI/CD. → Details: modes/enterprise.md

Mobile Mode

Cross-platform Expo + React Native with enterprise standards. → Details: modes/mobile.md

Workflow

Phase 1: Mode Selection & Prerequisites

  1. Detect mode from user request

  2. If ambiguous, ask which type:

    • Sandbox: Quick experiments, minimal setup
    • Enterprise: Production web apps, full tooling
    • Mobile: Cross-platform iOS/Android apps
  3. Validate prerequisites:

    bash
    node --version  # >= 18.x
    npm --version   # >= 9.x
    
  4. Get project name and validate:

    • Valid directory name
    • No conflicts with existing directories

Phase 2: Mode-Specific Setup

Execute the selected mode's workflow (see mode files for details).

Important Reminders

  • Sandbox is for experiments: Don't add testing/CI to sandbox mode
  • Enterprise defaults to yes: Testing and CI/CD are included by default
  • Mobile uses managed workflow: For ejected/bare workflow, provide manual guidance
  • Always strict TypeScript: All modes use strict mode
  • 80% coverage threshold: Enterprise and mobile enforce this

Limitations

  • Requires Node.js >= 18 and npm >= 9
  • Enterprise mode creates Next.js App Router projects only
  • Mobile mode uses Expo managed workflow only
  • Cannot scaffold into existing directories

Success Criteria

  • Prerequisites validated (Node.js, npm)
  • Project directory created
  • Framework scaffolded (Vite/Next.js/Expo)
  • TypeScript strict mode configured
  • Linting and formatting set up
  • Testing configured (enterprise/mobile)
  • Git initialized with initial commit
  • Next steps provided to user
