Scaffolding CLI for Strands Agents TypeScript projects

Scaffold a production-ready Strands Agents TypeScript project with one command.

npx create-strands-agent

create-strands-agent is an interactive CLI that generates a fully configured TypeScript project built on the Strands Agents SDK. It supports optional modules for agent memory, input/output guardrails, Google's Agent-to-Agent (A2A) protocol, and AWS AgentCore deployment.

Quick Start

npx create-strands-agent my-agent
cd my-agent
npm run dev

That's it. You'll have a working Strands agent running locally.

Features

• Interactive setup — guided prompts walk you through project configuration
• Non-interactive mode — use flags for CI/CD pipelines and automation
• Modular architecture — pick only the modules you need
• TypeScript-first — strict mode, ESM, ES2022 target
• Multiple package managers — npm, yarn, or pnpm

Optional Modules

Module	Description
Memory	Persist and recall agent context across interactions. Includes a local file-based provider for development with inline guidance on swapping to production stores.
Guardrails	Input and output safety constraints. Generates example guardrails demonstrating content validation and response filtering.
A2A	Google's Agent-to-Agent protocol support. Generates an A2A server and agent card so your agent can communicate with other agents.
AgentCore	AWS AgentCore deployment configuration. Generates a Dockerfile, deployment script, and AgentCore config for deploying to AWS.

Usage

Interactive Mode

Run without arguments to get the full interactive experience:

npx create-strands-agent

You'll be prompted for:

1. Project name — the directory name and package name
2. Package manager — npm, yarn, or pnpm
3. Modules — select from Memory, Guardrails, A2A, and AgentCore
4. Confirmation — review your selections before generating

If the target directory already exists and is non-empty, you'll be asked to overwrite, merge, or cancel.

With a Project Name

Pass the project name as an argument to skip that prompt:

npx create-strands-agent my-agent

Non-Interactive Mode

Use --yes to skip all prompts and use defaults:

npx create-strands-agent my-agent --yes

Defaults: npm as package manager, no optional modules, dependencies installed automatically.

CLI Flags

Flag	Description
-y, --yes	Skip interactive prompts, use defaults
-m, --modules <list>	Comma-separated modules: memory, guardrails, a2a, agentcore
--package-manager <pm>	Package manager: npm, yarn, or pnpm
--no-install	Skip automatic dependency installation
-V, --version	Display the CLI version
-h, --help	Display usage information

Examples

Scaffold with memory and guardrails using yarn:

npx create-strands-agent my-agent --modules memory,guardrails --package-manager yarn

Scaffold with all modules, no install (useful in CI):

npx create-strands-agent my-agent --yes --modules memory,guardrails,a2a,agentcore --no-install

Scaffold with A2A support using pnpm:

npx create-strands-agent my-agent --modules a2a --package-manager pnpm

Generated Project Structure

A scaffold with all modules selected produces:

Module directories are only included when their corresponding module is selected.

Generated Project Scripts

Every generated project includes these npm scripts:

Script	Command	Description
dev	tsx watch src/index.ts	Run the agent in development mode with hot-reload
build	tsc	Compile TypeScript to JavaScript
start	node dist/index.js	Run the compiled agent in production mode
lint	eslint src/	Run ESLint on the project source
lint:fix	eslint src/ --fix	Lint and auto-fix issues
format	prettier --write src/	Format code with Prettier
format:check	prettier --check src/	Check formatting without changes

Requirements

• Node.js >= 20 — the CLI checks your Node version at startup and exits with a clear message if it's too low.

How It Works

The CLI follows a pipeline architecture:

1. Parse CLI args — Commander.js handles flags and the positional project name
2. Collect config — interactive prompts via @inquirer/prompts, or defaults from flags
3. Render templates — EJS templates are filtered by selected modules and rendered with your configuration
4. Install dependencies — runs the selected package manager's install command
5. Display next steps — shows commands to run, documentation links, and module-specific instructions

Templates are bundled in the package under templates/. Each module has its own template directory, and a manifest controls which files are generated based on your selections.

Development

Setup

git clone https://github.com/tverney/create-strands-agent.git
cd create-strands-agent
npm install

Running Tests

npm test

The test suite includes:

• Property-based tests (fast-check) — verify correctness properties across all valid input combinations with 100+ iterations each
• Unit tests (Vitest) — cover validators, utilities, CLI argument parsing, and error handling
• Integration tests — scaffold real projects to temp directories and run tsc --noEmit to verify TypeScript compilation

Building

npm run build

Testing Locally

After building, you can test the CLI locally:

node bin/create-strands-agent.js my-test-project

Or link it globally:

npm link
create-strands-agent my-test-project
