AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides a structured approach to deploying serverless applications on AWS. It supports both AWS SAM and AWS CDK, offering guidance on project scaffolding, IaC template management, Lambda function constructs, and CI/CD pipeline integration. It includes best practices for resource configuration, environment management, and testing, while providing specific hooks for SAM template validation and automated deployment workflows.
What it does
- Provides project scaffolding for both SAM and CDK serverless applications.
- Offers guidance on using L2 CDK constructs for optimized Lambda function deployment.
- Automates SAM template validation via a post-edit hook.
- Supports multi-environment deployment strategies using configuration files.
- Facilitates the integration of CI/CD pipelines for serverless infrastructure.
- Provides reference material for SAM and CDK coexistence and migration.
When to use it
- When initializing a new serverless project on AWS.
- When you need to define Lambda functions using optimized CDK constructs like NodejsFunction.
- When you require automated validation for your SAM templates.
- When setting up infrastructure-as-code for serverless resources like DynamoDB, SQS, or API Gateway.
- When migrating or managing a project that uses both SAM and CDK.
Advantages
- Promotes the use of L2 constructs for safer, least-privilege IAM policies.
- Enables type-safe infrastructure development using TypeScript with CDK.
- Reduces manual errors through automated template validation.
- Simplifies complex resource wiring with pre-defined serverless patterns.
- Supports deterministic synthesis through cached context files.
Usage examples
- “Initialize a new serverless project using CDK with TypeScript.”
- The agent will guide you through the cdk init process, setting up the project structure with bin, lib, and test directories.
- “How do I define a Lambda function in CDK using NodejsFunction?”
- The agent will provide a code snippet demonstrating the NodejsFunction construct, including configuration for runtime, memory, and esbuild bundling.
- “Validate my current SAM template.”
- The agent will trigger the sam validate command to check your template.yaml for syntax and configuration errors.

AWS Serverless Deployment
Deploy serverless applications to AWS using SAM or CDK. This skill covers project scaffolding, IaC templates, CDK constructs and patterns, deployment workflows, CI/CD pipelines, and SAM/CDK coexistence.
For Lambda runtime behavior, event sources, orchestration, observability, and optimization, see the aws-lambda skill.
When to Load Reference Files
Load the appropriate reference file based on what the user is working on:
SAM project setup, templates, deployment workflow, local testing, or container images -> see references/sam-project-setup.md
CDK project setup, constructs, CDK testing, or CDK pipelines -> see references/cdk-project-setup.md
CDK Lambda constructs, NodejsFunction, PythonFunction, or CDK Function -> see references/cdk-lambda-constructs.md
CDK serverless patterns, API Gateway CDK, Function URL CDK, EventBridge CDK, DynamoDB CDK, or SQS CDK -> see references/cdk-serverless-patterns.md
SAM and CDK coexistence, migrating from SAM to CDK, or using sam build with CDK -> see references/sam-cdk-coexistence.md
Best Practices
SAM
Do: Use
sam_initwith an appropriate template for your use caseDo: Set global defaults for timeout, memory, runtime, and tracing in the
GlobalssectionDo: Use
samconfig.tomlenvironment-specific sections for multi-environment deploymentsDo: Use
sam build --use-containerwhen native dependencies are involvedDon't: Copy-paste templates from the internet without understanding the resource configuration
Don't: Hardcode resource ARNs or account IDs in templates — use
!Ref,!GetAtt, and!Sub
CDK
Do: Use TypeScript — type checking catches errors at synthesis time, before any AWS API calls
Do: Prefer L2 constructs and
grant*methods over L1 and raw IAM statementsDo: Separate stateful and stateless resources into different stacks; enable termination protection on stateful stacks
Do: Commit
cdk.context.jsonto version control — it caches VPC/AZ lookups for deterministic synthesisDo: Write unit tests with
aws-cdk-lib/assertions; assert logical IDs of stateful resources to detect accidental replacementsDo: Use
cdk diffin CI before every deployment to review changesDon't: Hardcode account IDs or region strings — use
this.accountandthis.regionDon't: Use
cdk deploydirectly in production without a pipelineDon't: Skip
cdk bootstrap— deployments will fail without the CDK toolkit stack
Configuration
AWS CLI Setup
This skill requires that AWS credentials are configured on the host machine:
Verify access: Run aws sts get-caller-identity to confirm credentials are valid
SAM CLI Setup
Verify: Run sam --version
Container Runtime Setup
Install a Docker compatible container runtime: Required for
sam_local_invokeand container-based buildsVerify: Use an appropriate command such as
docker --versionorfinch --version
AWS Serverless MCP Server
Write access is enabled by default. The plugin ships with --allow-write in .mcp.json, so the MCP server can create projects, generate IaC, and deploy on behalf of the user.
Access to sensitive data (like Lambda and API Gateway logs) is not enabled by default. To grant it, add --allow-sensitive-data-access to .mcp.json.
SAM Template Validation Hook
This plugin includes a PostToolUse hook that runs sam validate automatically after any edit to template.yaml or template.yml. If validation fails, the error is returned as a system message so you can fix it immediately. The hook requires SAM CLI and jq to be installed; if either is missing, validation is skipped with a system message. Users can disable it via /hooks.
Verify: Run jq --version
IaC framework selection
Default: CDK
Override syntax:
"use CloudFormation" → Generate YAML templates
"use SAM" → Generate YAML templates
When not specified, ALWAYS use CDK
Language selection for CDK
Default: TypeScript
Override syntax:
"use Python" → Generate Python code
"use JavaScript" → Generate JavaScript code
When not specified, ALWAYS use TypeScript
Error Scenarios
Serverless MCP Server Unavailable
Inform user: "AWS Serverless MCP not responding"
Ask: "Proceed without MCP support?"
DO NOT continue without user confirmation
