A development and deployment guide for AWS Amplify Gen 2, a TypeScript-based toolkit for building full-stack web and mobile applications on AWS. It covers sign-in, data, storage, functions, APIs, and AI features across several app frameworks.

Use it to create and deploy web or mobile apps with AWS services such as Cognito, AppSync, DynamoDB, S3, Lambda-style functions, and Bedrock-based AI.

It brings the frontend, cloud backend, authentication, database, file storage, and deployment steps into one workflow.

aws-amplify — Skill for Claude Code and Codex by aws

About the project

Agent Toolkit for AWS is a collection of AWS-supported MCP servers, skills, plugins, commands, and hooks that help AI coding agents build, deploy, and manage applications on AWS. It is used by developers working with AWS services through agents such as Claude Code, Codex, Cursor, and Kiro. The catalogue entries are the toolkit's own agent extensions for AWS development and operations.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00205	$0.03696
Opus 5	$0.00102	$0.01848
Sonnet 5	$0.00041	$0.00739
Haiku 4.5	$0.00020	$0.00370

Security

Grade A, and why

aws-amplify scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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: Default to React (Vite) and explain the choice.
Mobile: Ask which platform (Flutter, Swift, Android, or React Native) — there is no universal mobile default, so guessing leads to wasted effort.
Neither specified: If the user says "build an app" without clarifying web vs. mobile, ask before proceeding — the framework choice affects every subsequent step.
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: Default to npm unless the user specifies yarn or pnpm.
Language: Default to TypeScript. Gen2 backends are TypeScript-only; frontends should follow the project's existing language.
Next.js: Default to App Router unless the user specifies Pages Router.
React Native: Ask whether the user uses 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 defaultAuthorizationMode: 'userPool'.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
