Installation

Add the marketplace to Claude Code:

/plugin marketplace add zxkane/aws-skills

Install plugins individually:

/plugin install aws-cdk@aws-skills
/plugin install aws-cost-ops@aws-skills
/plugin install serverless-eda@aws-skills

Core CDK Principles

Resource Naming

Do NOT explicitly specify resource names when they are optional in CDK constructs.

// ✅ GOOD - Let CDK generate unique names
new lambda.Function(this, 'MyFunction', {
  // No functionName specified
});

// ❌ BAD - Prevents multiple deployments
new lambda.Function(this, 'MyFunction', {
  functionName: 'my-lambda',
});

Lambda Functions

Use appropriate constructs for automatic bundling:

• TypeScript/JavaScript: NodejsFunction from aws-cdk-lib/aws-lambda-nodejs
• Python: PythonFunction from @aws-cdk/aws-lambda-python-alpha

Pre-Deployment Validation

Before committing CDK code:

npm run build
npm test
npm run lint
cdk synth
./scripts/validate-stack.sh

Usage Examples

CDK Development

Ask Claude to help with CDK:

Create a CDK stack with a Lambda function that processes S3 events

Claude will:

• Follow CDK best practices
• Use NodejsFunction for automatic bundling
• Avoid explicit resource naming
• Grant proper IAM permissions
• Use MCP servers for latest AWS information

Cost Optimization

Estimate costs before deployment:

Estimate the monthly cost of running 10 Lambda functions with 1M invocations each

Analyze current spending:

Show me my AWS costs for the last 30 days broken down by service

Monitoring and Observability

Set up monitoring:

Create CloudWatch alarms for my Lambda functions to alert on errors and high duration

Investigate issues:

Show me CloudWatch logs for my API Gateway errors in the last hour

Security and Audit

Audit activity:

Show me all IAM changes made in the last 7 days

Assess security:

Run a Well-Architected security assessment on my infrastructure

Serverless Development

Build serverless applications:

Create a serverless API with Lambda and API Gateway for user management

Implement event-driven workflow:

Create an event-driven order processing system with EventBridge and Step Functions

Orchestrate complex workflows:

Implement a saga pattern for booking flights, hotels, and car rentals with compensation logic

MCP Server Names

MCP server names use short identifiers to comply with Bedrock's 64-character tool name limit. The naming pattern is: mcp__plugin_{plugin}_{server}__{tool}

Examples: awsdocs (AWS docs), cdk (CDK), cw (CloudWatch), sfn (Step Functions), sam (Serverless), etc.
