AWS Lambda Serverless Development

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 for guidance
• Lambda Managed Instances: Run Lambda on dedicated EC2 instances with managed lifecycle — see the managed-instances skill for evaluation, configuration, and migration guidance
• Schema Management: Type-safe EventBridge integration with schema registry
• Observability: CloudWatch logs, metrics, and X-Ray tracing
• Performance Optimization: Right-sizing, cost optimization, and troubleshooting

When to Load Reference Files

Load the appropriate reference file based on what the user is working on:

• Getting started, what to build, project type decision, or working with existing projects -> see references/getting-started.md
• SAM, CDK, deployment, IaC templates, CDK constructs, or CI/CD pipelines -> see the aws-serverless-deployment skill (separate skill in this plugin)
• Web app deployment, Lambda Web Adapter, API endpoints, CORS, authentication, custom domains, or sam local start-api -> see references/web-app-deployment.md
• Event sources, DynamoDB Streams, Kinesis, SQS, Kafka, S3 notifications, or SNS -> see references/event-sources.md
• EventBridge, event bus, event patterns, event design, Pipes, or schema registry -> see references/event-driven-architecture.md
• Durable functions, checkpointing, replay model, saga pattern, or long-running Lambda workflows -> see the durable-functions skill (separate skill in this plugin with full SDK reference, testing, and deployment guides)
• Lambda Managed Instances, LMI, capacity providers, multi-concurrency, EC2-backed Lambda, cold start elimination, or Lambda cost optimization with Reserved Instances -> see the managed-instances skill (separate skill in this plugin for evaluation, configuration, and migration)
• Orchestration, workflows, or Durable Functions vs Step Functions -> see references/orchestration-and-workflows.md
• Step Functions, ASL, state machines, JSONata, Distributed Map, SDK integrations, TestState API, mocking service integrations, or state machine unit tests -> see the aws-step-functions skill for comprehensive guidance
• Observability, logging, tracing, metrics, alarms, or dashboards -> see references/observability.md
• Optimization, cold starts, memory tuning, cost, or streaming -> see references/optimization.md
• Powertools, idempotency, feature flags, parameters, parser, batch processing, or data masking -> see references/powertools.md
• Troubleshooting, errors, debugging, or deployment failures -> see references/troubleshooting.md

Best Practices

Project Setup

• Do: Use sam_init or cdk init with an appropriate template for your use case
