## What it does

This skill guides the setup of AWS Amplify Gen2 backends and client frontends. It covers TypeScript configurations for Cognito auth, AppSync with DynamoDB models, S3 storage, and Lambda functions. It also handles Bedrock integration via Amplify AI Kit. Supported client platforms include React, Next.js, Vue, React Native, Flutter, Swift, and Android.

The skill triggers whenever an `amplify/` directory or `amplify_outputs` file is present, or when files import `@aws-amplify`. For local sandboxes, you need `npx ampx`, Node.js (^18.19.0, ^20.6.0, or >=22), and valid AWS credentials verified via `aws sts get-caller-identity`. Gen2 backends run strictly on TypeScript.

Do not use this skill for legacy Amplify Gen1 or standalone CDK setups without Amplify. By default, web tasks without an explicit framework choice route to React with Vite, starting with `publicApiKey` data authorization until user pools are configured.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill amplify-workflow -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/amplify-workflow/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/amplify-workflow/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill amplify-workflow -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/amplify-workflow/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill amplify-workflow -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/amplify-workflow/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cline/skills amplify-workflow
```

2. **Manually: put the files in place**
- File: `.github/skills/amplify-workflow/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill amplify-workflow -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cline/skills --path skills/amplify-workflow
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/amplify-workflow/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill amplify-workflow -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/cline/skills/tree/HEAD/skills/amplify-workflow/SKILL.md

## When to use it
- define TypeScript backends using defineAuth and defineData
- set up Cognito authentication and authorization rules
- model AppSync GraphQL schemas and DynamoDB relationships
- connect frontend frameworks to local ampx sandboxes

## Example prompts
- Configure an Amplify Gen2 backend with Cognito auth and S3 storage
- Define AppSync data models with owner-based rules for a Next.js app
- Help set up an ampx sandbox for local backend testing

# AWS Amplify Gen2

Build and deploy full-stack applications using AWS Amplify Gen2's TypeScript
code-first approach. This skill covers backend resource creation, frontend
integration across 8 frameworks, and deployment workflows.

## Prerequisites

- Node.js ^18.19.0 || ^20.6.0 || >=22 and npm
- AWS credentials configured (`aws sts get-caller-identity` succeeds)
- For sandbox: `npx ampx --version` returns a valid version
- For mobile: Platform-specific tooling (Xcode, Android Studio, Flutter SDK)

## Defaults & Assumptions

When the user does not specify a framework:

- **Web:** You **SHOULD** default to **React** (Vite) and explain the choice.
- **Mobile:** You **MUST** ask which platform the user wants (Flutter,
  Swift, Android, or React Native). There is no universal mobile default.
- **Neither specified:** If the user says "build an app" without clarifying web
  vs. mobile, you **MUST** ask before proceeding.
- **Backend only:** If only backend changes are requested and no frontend
  framework is mentioned, skip the frontend integration step entirely.

When the user does not specify tooling or strategy:

- **Package manager:** You **SHOULD** default to **npm** unless the user
  specifies yarn or pnpm.
- **Language:** You **SHOULD** default to **TypeScript**. Gen2 backends are
  TypeScript-only; frontends **SHOULD** follow the project's existing language.
- **Next.js:** You **SHOULD** default to **App Router** unless the user
  specifies Pages Router.
- **React Native:** Ask the user whether they use **Expo** or **bare
  React Native CLI**.
- **Auth:** You **MUST** ask which login method the user wants
  (email/password, social login, SAML, passwordless, etc.). Do not assume a default.
- **Data authorization:** default to **`publicApiKey`**
  (`allow.publicApiKey()`) — this is the starter template default. When
  auth is added, switch to **owner-based** (`allow.owner()`) with
```
