3	Domain expertise for building serverless applications on AWS: Lambda, API Gateway, Step Functions, EventBridge, event source mappings, concurrency, cold starts, deployment, and troubleshooting.
4
5	Works best with the [AWS MCP server](https://docs.aws.amazon.com/aws-mcp/) — run CLI commands, query CloudWatch, validate configs directly. All guidance also works with standard AWS CLI access.

7	## Specialized skills — check these first
8
9	These cover capabilities and procedures the general references below do not. Several are specialized features or step-by-step tested procedures you would otherwise miss. Route to the matching skill before falling back to the references.

11	### Advanced Lambda compute (easy to overlook)
12
13	\| Use this skill \| When the workload involves \|
14	\|---\|---\|
15	\| aws-lambda-microvms \| Strong tenant isolation, sandboxed/untrusted code execution (AI agent code sandboxes, REPLs, notebooks, CI runners), long-lived sessions, suspend/resume with preserved state, port-listening servers (gRPC, WebSocket, custom TCP), Firecracker microVMs, snapshot-resumable compute, up to 8-hour lifetimes \|
16	\| aws-lambda-durable-functions \| Durable execution, checkpoint-and-replay, long-running multi-step workflows written as plain code (TS/Python/Java), automatic state persistence, saga pattern in code, human-in-the-loop callbacks, executions up to 1 year, `context.step`/`context.wait`/`context.invoke`, `withDurableExecution`, `durable-execution-sdk` \|
17	\| aws-lambda-managed-instances \| Lambda Managed Instances (LMI), capacity providers, EC2-backed Lambda, steady high-volume traffic (50M+ req/mo) wanting Savings Plans / Reserved Instance pricing, `PerExecutionEnvironmentMaxConcurrency`, `CapacityProviderConfig`, multi-concurrent execution environments \|

25	\| creating-api-gateway-stage \| Create an API Gateway stage with CloudWatch logging, X-Ray tracing, throttling, WAF association, and authorization \|
26	\| deploying-custom-domain-rest-api \| Deploy a Regional REST API with custom domain: ACM cert, Lambda backend, request authorizer, base path mapping, Route 53 DNS \|
27	\| debugging-lambda-timeouts \| Systematically diagnose a timing-out Lambda: config, CloudWatch logs/metrics, VPC, cold starts, memory, downstream calls \|
28	\| processing-s3-uploads-with-step-functions \| Deploy an event-driven workflow: S3 upload → EventBridge → Step Functions → Lambda (small files) or Fargate (large files), with VPC/ECR/ECS/IAM \|
