AWS CDK Development

This skill provides comprehensive guidance for developing AWS infrastructure using the Cloud Development Kit (CDK), with integrated MCP servers for accessing latest AWS knowledge and CDK utilities.

AWS Documentation Requirement

Always verify AWS facts using MCP tools (mcp__aws-mcp__* or mcp__*awsdocs*__*) before answering. The aws-mcp-setup dependency is auto-loaded — if MCP tools are unavailable, guide the user through that skill's setup flow.

CDK-Specific MCP Guidance

AWS Labs replaced the dedicated CDK MCP server (awslabs.cdk-mcp-server) with the broader awslabs.aws-iac-mcp-server, which covers CDK alongside CloudFormation and other AWS infrastructure-as-code workflows.

For CDK construct lookups, best-practice recommendations, and pattern guidance, install awslabs.aws-iac-mcp-server. It ships in the deploy-on-aws plugin from awslabs/agent-plugins, or can be registered directly with claude mcp add aws-iac uvx awslabs.aws-iac-mcp-server@latest.

When to reach for it:

CDK construct recommendations and API lookups
CDK and CloudFormation best-practice patterns
Validation of synthesized templates
Cross-resource configuration guidance

When to Use This Skill

Use this skill when:

Creating new CDK stacks or constructs
Refactoring existing CDK infrastructure
Implementing Lambda functions within CDK
Following AWS CDK best practices
Validating CDK stack configurations before deployment
Verifying AWS service capabilities and regional availability

Core CDK Principles

Resource Naming

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

Why: CDK-generated names enable:

Reusable patterns: Deploy the same construct/pattern multiple times without conflicts
Parallel deployments: Multiple stacks can deploy simultaneously in the same region
Cleaner shared logic: Patterns and shared code can be initialized multiple times without name collision
