Aws Serverless

This is a comprehensive reference for building event-driven apps on AWS without managing servers. It covers the full stack: Lambda functions, API Gateway routing, Step Functions orchestration, EventBridge patterns, and all the event sources (SQS, DynamoDB Streams, S3). The troubleshooting guide starts with the five most common fixes, which is exactly what you need when debugging a 502 at 2am. It includes concrete guidance on cold starts, concurrency tuning, and production readiness checklists. Works especially well with the AWS MCP server for running CLI commands directly. The routing table is well organized, so you can jump straight to event source configuration or SAM deployment templates without reading everything first.

AWS Serverless

Overview

This skill is the router for serverless work on AWS. It makes one opinionated recommendation for each application component and each raised decision dimension (form factor + capacity provider + orchestration + feature choices), then hands off to every specialized skill needed for that composition. Do not force a multi-component application onto one form factor. This skill keeps only the shared Lambda reference material that has no dedicated skill.

Works best with the AWS MCP server — recommended for sandboxed command execution and audit logging. All guidance also works with standard AWS CLI access.
