AWS Serverless & Event-Driven Architecture Expert

Designs and implements AWS serverless and event-driven systems (Lambda, API Gateway, EventBridge, Step Functions) following Well-Architected Serverless Lens principles.

What it does

Applies the seven Well-Architected serverless design principles: single-purpose functions, concurrency-first design, share nothing, no hardware affinity, state-machine orchestration instead of Lambda chaining, event-triggered transactions, and idempotent operations.
Supplies CDK/TypeScript examples for Lambda, API Gateway (REST/HTTP), DynamoDB, Step Functions, EventBridge, SQS, and SNS.
Enforces operational essentials: dead letter queues, partial batch failure handling, exponential-backoff retries, X-Ray tracing, and Lambda Powertools instrumentation.
Points to bundled reference docs for EDA patterns (event router, queue processing, fan-out, saga, event sourcing) and serverless patterns (microservice APIs, Kinesis streams, scheduled jobs, webhooks), plus security, observability, performance, and deployment guides.
Requires AWS facts to be verified through AWS documentation MCP tools before answering.

Who it's for

Backend engineers building serverless APIs or microservices on AWS.
Teams introducing async processing, queues, pub/sub, or distributed transactions.
Cloud engineers writing CDK infrastructure who want best-practice review.

Example uses

"Design an order-processing pipeline with EventBridge + SQS + Lambda" → a CDK stack with event schema, routing rules, DLQ, and alarms.
"Coordinate payment, shipping, and notification safely" → a Step Functions saga with compensating actions instead of Lambda chaining.
"My SQS consumer double-processes messages" → refactor to DynamoDB-backed idempotency checks and batchItemFailures partial retries.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/zxkane/aws-skills/HEAD/plugins/serverless-eda/skills/aws-serverless-eda/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)

Download the ZIP with the button below.
In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

↓ Download ZIP

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the plugins/serverless-eda/skills/aws-serverless-eda folder from the GitHub repo zxkane/aws-skills into my ~/.claude/skills/aws-serverless-eda/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/zxkane/aws-skills.git && mkdir -p ~/.claude/skills && cp -r aws-skills/plugins/serverless-eda/skills/aws-serverless-eda ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

Open a terminal and change into your working directory.
Clone the repo: git clone https://github.com/zxkane/aws-skills.git
Create the skills folder: mkdir -p ~/.claude/skills
Copy the skill: cp -r aws-skills/plugins/serverless-eda/skills/aws-serverless-eda ~/.claude/skills/
Confirm the references/ folder came along with it.
Optionally copy the companion aws-mcp-setup and aws-cdk-development skills so the MCP tooling works end to end.
Verify your AWS credentials: aws sts get-caller-identity
Restart Claude Code and ask something like "design a serverless API with Lambda" to trigger the skill.
