AWS development best practices for Lambda, SAM, CDK, DynamoDB, IAM, and serverless architecture using Infrastructure as Code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# AWS Development Best Practices
## Overview
This skill provides comprehensive guidelines for developing applications on Amazon Web Services (AWS), focusing on serverless architecture, Infrastructure as Code, and security best practices.
## Core Principles
- Write clean, well-structured code with accurate AWS SDK examples
- Use Infrastructure as Code (Terraform, CDK, SAM) for all infrastructure
- Follow the principle of least privilege for all IAM policies
- Implement comprehensive logging, metrics, and tracing for observability
## AWS Lambda Guidelines
### Configuration Standards
- Use TypeScript implementation on ARM64 architecture for better performance and cost
- Set appropriate memory and timeout values based on workload requirements
- Use environment variables for configuration, never hardcode values
- Implement proper error handling and retry logic
### Lambda Best Practices
```typescript
// Use ES modules and typed handlers
import { APIGatewayProxyHandler } from 'aws-lambda';
export const handler: APIGatewayProxyHandler = async (event) => {
try {
// Validate input at function start
if (!event.body) {

How to install
mdr add mindrally/skills/aws-development@sha256:240e89eed5e3ace4The line at the top of this page pins the label git:20261008.7682ca7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
