aws-cloudformation-lambda from giuseppe-trisciuoglio/developer-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add giuseppe-trisciuoglio/developer-kit/aws-cloudformation-lambda@git:20260324.a02e282

Pins git:20260324.a02e282 in mdr.lock. Pin the fingerprint instead.

Provides AWS CloudFormation patterns for Lambda functions, layers, API Gateway integration, event sources, cold start optimization, monitoring, logging, template validation, and deployment workflows. Use when creating Lambda functions with CloudFormation, configuring event sources, implementing cold start optimization, managing layers, integrating with API Gateway, and deploying Lambda infrastructure.

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.

What the file says

# AWS CloudFormation Lambda Functions

## Overview

Create production-ready Lambda functions using CloudFormation templates with validation and deployment workflows.

## When to Use

- Creating Lambda functions with CloudFormation
- Configuring event sources (S3, SQS, DynamoDB, Kinesis)
- Implementing Lambda layers and cold start optimization
- Integrating Lambda with API Gateway
- Deploying Lambda infrastructure with validation

## Deployment Workflow

Always follow this deployment workflow:

### 1. Validate Template
```bash
aws cloudformation validate-template --template-body file://template.yaml
```

### 2. Deploy Stack
```bash
aws cloudformation deploy \
  --template-file template.yaml \
  --stack-name my-lambda-stack \
  --capabilities CAPABILITY_IAM \
  --parameter-overrides Environment=prod
```

### 3. Monitor Stack Events
```bash
aws cloudformation describe-stack-events \
  --stack-name my-lambda-stack \
  --query 'StackEvents[?ResourceStatus==`CREATE_FAILED`||ResourceStatus==`UPDATE_FAILED`]'
```

### 4. Verify Resources
```bash
aws lambda get-function --function-name my-lambda-stack-function
aws cloudformation describe-stacks --stack-name my-lambda-stack \
…

How to install

The exact contents, by fingerprint

mdr add giuseppe-trisciuoglio/developer-kit/aws-cloudformation-lambda@sha256:4bf2026728f508c6

The line at the top of this page pins the label git:20260324.a02e282, 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.
