次のような場合に使用: Auth0（認証サービス）をアプリに追加したいものの、どのSDK（開発ツール）やスキルを選べばよいか判断に迷っているとき。 プロジェクトで使用されているフレームワーク（開発環境）を自動判別し、適切なセットアップの手順へ案内します。ユーザーが「ログイン機能を追加したい」「Auth0を設定したい」と具体的なフレームワーク名を明示しない場合でも、このスキルを最初の入口として活用できます。
Use when adding Auth0 authentication to any app and unsure which SDK or skill to use. Detects the project's framework and routes to the right setup workflow — use this as the entry point even if the user just says "add login to my app" or "set up Auth0" without naming a framework.
Detect your framework and get started with Auth0 authentication.
Run this command to identify your framework:
# Check package.json dependencies (Node.js projects)
cat package.json | grep -E "react|next|vue|nuxt|angular|express|fastify|@nestjs|expo"
# Or check project files
ls -la | grep -E "angular.json|vue.config.js|next.config|app.json|Package.swift|build.gradle"
Framework Detection Table:
| Framework | Detection | Skill to Use |
|---|---|---|
| React (Vite/CRA) | "react" in package.json, no Next.js |
auth0-react |
| Next.js | "next" in package.json |
auth0-nextjs |
| Vue.js | "vue" in package.json, no Nuxt |
auth0-vue |
| Nuxt | "nuxt" in package.json |
auth0-nuxt |
| Angular | angular.json exists or "@angular/core" |
auth0-angular |
| Express.js | "express" in package.json |
auth0-express |
| Fastify (web app) | "fastify" in package.json, has @fastify/view |
auth0-fastify |
| Fastify (API) | "fastify" in package.json, no view engine |
auth0-fastify-api |
| React Native | "react-native" or "expo" in package.json |
auth0-react-native |
| Flask | "flask" in requirements.txt, Pipfile, or pyproject.toml |
auth0-flask |
| Node.js API | "express-oauth2-jwt-bearer" in package.json |
express-oauth2-jwt-bearer |
| ASP.NET Core web app | *.csproj exists, has Views/ or Pages/ folder |

macOS/Linux:
brew install auth0/auth0-cli/auth0
Windows:
scoop install auth0
# Or: choco install auth0-cli
Full installation guide: See CLI Reference
auth0 login
This opens your browser to authenticate with Auth0.
Choose application type based on your framework:
Single Page Applications (React, Vue, Angular):
auth0 apps create --name "My App" --type spa \
--auth-method None \
--callbacks "http://localhost:3000" \
--logout-urls "http://localhost:3000" \
--metadata "created_by=agent_skills"
Regular Web Apps (Next.js, Nuxt, Express, Fastify):
auth0 apps create --name "My App" --type regular \
--callbacks "http://localhost:3000/api/auth/callback" \
--logout-urls "http://localhost:3000" \
--metadata "created_by=agent_skills"
Native Apps (React Native):
auth0 apps create --name "My App" --type native \
--auth-method None \
--callbacks "myapp://callback" \
--logout-urls "myapp://logout" \
--metadata "created_by=agent_skills"
Get your credentials:
auth0 apps list # Find your app
auth0 apps show <app-id> # Get client ID and secret
More CLI commands: See CLI Reference
After creating your application, apply branding so the Auth0 Universal Login page matches your app:
auth0 ul update \
--accent "#YOUR_BRAND_COLOR" \
--background "#YOUR_BACKGROUND_COLOR" \
--logo "https://your-app.com/logo.png" \
--favicon "https://your-app.com/favicon.ico"
This ensures users see your app's branding on the login screen instead of the default Auth0 branding. You can also use the acul-screen-generator skill for full custom login screen design.
Based on your framework detection, use the appropriate skill:

Migrating from another auth provider? Use the auth0-migration skill.
The migration skill covers:
Framework-specific environment variable setup:
Core concepts and troubleshooting:
Complete Auth0 CLI reference:
| Mistake | Fix |
|---|---|
| Wrong application type | SPAs need "Single Page Application", server apps need "Regular Web Application", mobile needs "Native" |
| Callback URL not configured | Add your app's callback URL to Allowed Callback URLs in Auth0 Dashboard |
| Using wrong credentials | Client Secret only needed for Regular Web Apps, not SPAs |
| Hardcoding credentials in code | Always use environment variables, never commit secrets to git |
| Not testing locally first | Set up localhost URLs in Auth0 before deploying to production |
| Mixing application types | Don't use SPA SDK for server-side apps or vice versa |
