Overview
AWS Skills is zxkane/aws-skills, an MIT-licensed set of Claude Code plugins and Agent Skills for building on AWS. Each plugin pairs written guidance with AWS MCP server integrations, so Claude can follow established patterns and also look up current AWS information instead of relying on training data.
Plugins
- aws-common (dependency): shared skills including setup for the AWS Documentation MCP server, loaded by the other plugins.
- aws-iac (AWS CDK): CDK best practices, a pre-deployment validation script, and a patterns reference, with the AWS CDK MCP server.
- aws-cost-ops: cost estimation, monitoring, and operational practices, with the AWS Pricing, AWS Cost Explorer, and Amazon CloudWatch MCP servers.
- serverless-eda: Well-Architected serverless design, event-driven patterns, Step Functions orchestration, saga patterns, and event sourcing.
- aws-agentic-ai: Amazon Bedrock AgentCore, covering Gateway (REST APIs to MCP tools), Runtime, Memory, Identity, Code Interpreter, Browser, and Observability.
Individual skills are also published for skills.sh, including aws-cdk-development, aws-sst-development, aws-cost-operations, aws-serverless-eda, aws-agentic-ai, and aws-mcp-setup.
Quick Start
# Claude Code plugin marketplace
/plugin marketplace add zxkane/aws-skills
/plugin install aws-common@aws-skills
/plugin install aws-iac@aws-skills
# Or a single skill via skills.sh
npx skills add https://github.com/zxkane/aws-skills --skill aws-cdk-development
Then ask, for example, "Create a CDK stack with a Lambda function that processes S3 events".
What the CDK Guidance Enforces
- Do not set optional resource names such as
functionName, so stacks can be deployed more than once. - Use
NodejsFunction(TypeScript/JavaScript) orPythonFunctionfor automatic Lambda bundling. - Before committing, run
npm run build,npm test,npm run lint,cdk synth, and the bundledvalidate-stack.sh.
Use Cases
- Scaffolding CDK or SST infrastructure with consistent conventions.
- Reviewing serverless designs against Well-Architected patterns.
- Estimating and investigating AWS costs from the terminal.
- Deploying agents on Bedrock AgentCore.
Limitations
- The MCP-backed features need AWS credentials and the relevant MCP servers configured locally.
- Guidance reflects the author's conventions; review generated IAM permissions before deploying.
FAQ
Do I have to install every plugin?
No. Install aws-common first, then only the plugins you need.
Does it work outside Claude Code?
The individual skills install through skills.sh into other Agent Skills clients.
Alternatives
- Amazon Q Developer, AWS's own coding assistant.
- Amazon CloudWatch Omni for AWS observability.
