aws-lambda
Design, build, deploy, test, and debug serverless applications with AWS Lambda. Triggers on phrases like: Lambda function, event source, serverless application, API Gateway, EventBridge, Step Functions, serverless API, event-driven architecture, Lambda trigger. For deploying non-serverless apps to AWS, use deploy-on-aws plugin instead.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# AWS Lambda Serverless Development Design, build, deploy, and debug serverless applications with AWS serverless services. This skill provides access to serverless development guidance through the AWS Serverless MCP Server, helping you to build production-ready serverless applications with best practices built-in. Use SAM CLI for project initialization and deployment, Lambda Web Adapter for web applications, or Event Source Mappings for event-driven architectures. AWS handles infrastructure provisioning, scaling, and monitoring automatically. **Key capabilities:** - **SAM CLI Integration**: Initialize, build, deploy, and test serverless applications - **Web Application Deployment**: Deploy full-stack applications with Lambda Web Adapter - **Event Source Mappings**: Configure Lambda triggers for DynamoDB, Kinesis, SQS, Kafka - **Lambda durable functions**: Resilient multi-step applications with checkpointing — see the [durable-functions skill](../aws-lambda-durable-functions/) for guidance - **Lambda Managed Instances**: Run Lambda on dedicated EC2 instances with managed lifecycle — see the [managed-instances skill](../aws-lambda-managed-instances/) for evaluation, configuration, an

What does the aws-lambda skill do?
Design, build, deploy, test, and debug serverless applications with AWS Lambda. Triggers on phrases like: Lambda function, event source, serverless application, API Gateway, EventBridge, Step Functions, serverless API, event-driven architecture, Lambda trigger. For deploying non-serverless apps to AWS, use deploy-on-aws plugin instead.
How do I install it?
Run `npx skills add awslabs/agent-plugins --skill aws-lambda --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From awslabs/agent-plugins, a repository with 850 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
