AWS CDK Development

An opinionated guide for writing, validating, and deploying AWS infrastructure with the CDK.

Dev & CodingIntermediate★ 367⑂ 39AI score 9/10Last updated: Jun 15, 2026

What it does

  • Enforces core CDK principles when authoring stacks and constructs — most notably never hardcoding resource names so patterns stay reusable and stacks deploy in parallel.
  • Steers Lambda work toward the right construct per runtime (NodejsFunction, PythonFunction) so bundling and dependencies are handled automatically.
  • Provides a three-layer pre-deployment validation strategy: IDE feedback → cdk synth with cdk-nag Aspects → build, tests, and scripts/validate-stack.sh.
  • Follows an 8-step workflow: design → verify AWS services via MCP → implement → validate → synth → review → deploy → verify.
  • Uses AWS Documentation MCP and awslabs.aws-iac-mcp-server to confirm regional availability, quotas, and current API specs.

Who it's for

  • Backend and platform engineers building AWS infrastructure in TypeScript or Python CDK
  • Teams standardizing IaC/CloudFormation review quality
  • DevOps engineers rolling cdk-nag security checks into CI

Examples

  1. "Build a CDK stack with API Gateway, Lambda, and DynamoDB" → picks recommended constructs, omits explicit names, runs synth.
  2. "Validate this stack before I deploy" → installs cdk-nag, wires Aspects, runs cdk synth, documents any NagSuppressions reason.
  3. "Does Lambda support Python 3.13? Is DynamoDB in eu-south-2?" → verifies via AWS docs MCP before writing code.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/zxkane/aws-skills/HEAD/plugins/aws-iac/skills/aws-cdk-development/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the plugins/aws-iac/skills/aws-cdk-development folder from the GitHub repo zxkane/aws-skills into my ~/.claude/skills/aws-cdk-development/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/zxkane/aws-skills.git /tmp/aws-skills && mkdir -p ~/.claude/skills && cp -r /tmp/aws-skills/plugins/aws-iac/skills/aws-cdk-development ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and clone the repo: git clone https://github.com/zxkane/aws-skills.git
  2. Create the skills directory: mkdir -p ~/.claude/skills
  3. Copy the skill: cp -r aws-skills/plugins/aws-iac/skills/aws-cdk-development ~/.claude/skills/
  4. (Recommended) Register the MCP server: claude mcp add aws-iac uvx awslabs.aws-iac-mcp-server@latest
  5. Configure AWS credentials and confirm with aws sts get-caller-identity.
  6. Make sure Node.js and the CDK CLI are available: npx cdk --version
  7. Restart Claude Code and try a prompt like "create a CDK stack" to confirm the skill triggers.
