## What it does

The plugin groups skills around the main LocalStack development tasks. It covers emulator control through `lstk`, infrastructure deployment with Terraform, CDK, CloudFormation, and SAM, plus log inspection for troubleshooting. Other skills handle snapshots and Cloud Pods, review IAM policies and generate least-privilege permissions, or manage LocalStack extensions.

You need Docker running, a LocalStack account with an authentication token, and the `lstk` CLI. Install the infrastructure tools you intend to use and make sure they are on your `PATH`. Commands such as `lstk aws`, `lstk terraform`, `lstk cdk`, and `lstk sam` route supported tools to LocalStack. Pulumi requires `pulumilocal` because `lstk` does not provide a Pulumi proxy.

To install the plugin in Claude Code, add the community marketplace and then install `localstack@claude-community`. The older `localstack` CLI remains relevant for extension management and certain IAM policy generators, but it is deprecated. It controls its own container, so stop its emulator before starting another CLI's emulator to avoid running both at once.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install localstack@claude-community
```

## When to use it
- Start, stop, restart, or inspect a LocalStack environment
- Deploy AWS infrastructure with Terraform or CloudFormation
- Trace service failures by examining LocalStack logs
- Review IAM policies and generate least-privilege permissions
- Save and restore environment state using snapshots or Cloud Pods

## Example prompts
- Start LocalStack with `lstk` and check whether the local environment is running.
- Deploy my infrastructure to LocalStack with Terraform and investigate any deployment errors.
- Inspect the LocalStack logs, review the IAM policy, and suggest the minimum permissions required.

# LocalStack AI Skills

AI Agent Skills for developing and testing cloud applications against [LocalStack](https://localstack.cloud) - the local cloud development platform.

## Overview

This repository contains a collection of AI skills designed to help developers work more efficiently with LocalStack. These skills enable AI assistants to help with common LocalStack workflows, from managing the local environment to deploying infrastructure and analyzing logs.

## Available Skills

| Skill | Description |
|-------|-------------|
| [localstack-lifecycle](skills/localstack-lifecycle/) | Manage the emulator lifecycle with `lstk` (start, stop, status, restart, reset) |
| [iac-deployment](skills/iac-deployment/) | Deploy infrastructure using Terraform, CDK, CloudFormation, SAM, and Pulumi |
| [state-management](skills/state-management/) | Save, load, and manage LocalStack state with snapshots and Cloud Pods |
| [logs-analysis](skills/logs-analysis/) | Analyze LocalStack logs, identify errors, and debug issues |
| [iam-policy-analyzer](skills/iam-policy-analyzer/) | Analyze IAM policies and auto-generate least-privilege permissions |
| [localstack-extensions](skills/localstack-extensions/) | Manage LocalStack extensions and plugins (legacy CLI) |

## Installation

### Via the LocalStack standalone marketplace

```bash
claude plugin marketplace add localstack/skills
claude plugin install localstack@localstack-dev
```

## Prerequisites

- Docker running on your machine
- A [LocalStack account](https://app.localstack.cloud/) and auth token
- The [`lstk` CLI](https://docs.localstack.cloud/aws/developer-tools/running-localstack/lstk/), the current LocalStack CLI:

  ```bash
  # Homebrew (macOS/Linux)
  brew install localstack/tap/lstk

  # npm
  npm install -g @localstack/lstk

  # Authenticate
  lstk login
  ```

- The tools you want `lstk` to proxy, on your `PATH`: [AWS CLI](https://aws.amazon.com/cli/), `terraform`, `cdk`, or `sam`. `lstk aws`, `lstk terraform`, `lstk cdk`, and `lstk sam` point them at LocalStack for you, replacing the `awslocal`, `tflocal`, `cdklocal`, and `samlocal` wrappers.

### Optional extra CLIs

The `lstk` CLI does not cover every workflow yet. Install these only if you need them:

| Tool | Install | Needed for |
|------|---------|-----------|
| `pulumilocal` | `pip install pulumi-local` | Pulumi deployments — `lstk` has no Pulumi proxy |
| `samlocal` | `pip install aws-sam-cli-local` | Image/container-based Lambda (ECR) deploys and nested CloudFormation stacks, which `lstk sam` does not support |
| legacy `localstack` CLI | `pip install localstack` | LocalStack Extensions, and the `localstack aws iam stream` / `summary` policy generators |

The legacy `localstack` CLI is deprecated and will be removed in a future version — use it only for the gaps listed above. It manages its own container, so stop one CLI's emulator before starting the other's.

## Usage

These skills are designed to be used with AI coding assistants that support the skills/commands interface. Each skill provides contextual guidance and commands for specific LocalStack workflows.
