# 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
