# AWS Serverless

Specialized skill for building production-ready serverless applications on AWS.
Covers Lambda functions, API Gateway, DynamoDB, SQS/SNS event-driven patterns,
SAM/CDK deployment, and cold start optimization.

## Detailed Guide

Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

## Scope and validation

Before deployment confirm account/region, IAM scope, resource changes, data retention and budget. Review the synthesized template/change set and verify in a scoped development environment. Bundled material is documentation only; helper handlers and deployment files shown in snippets are not present or runtime-tested here. Secrets need approved managed storage and least-privilege roles; do not paste credentials into logs.

## Monitor memory usage

```javascript
exports.handler = async (event, context) => {
  const used = process.memoryUsage();
  console.log('Memory:', {
    heapUsed: Math.round(used.heapUsed / 1024 / 1024) + 'MB',
    heapTotal: Math.round(used.heapTotal / 1024 / 1024) + 'MB'
  });
  // ...
};
```

## When to Use
Use this skill when the request clearly matches the capabilities and patterns described above.

## Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
