AWS Lambda questions are easy to answer from stale memory or generic serverless patterns that ignore runtime limits, cold starts, and event source mappings. Use this skill to ground answers in the official AWS Lambda documentation and return the closest authoritative page instead of improvising deployment advice.
When to Use
Use this skill when the request is about:
- Lambda concepts: functions, handlers, runtimes, and execution environment
- Creating functions, deployment packages (zip), and container images
- Runtimes, layers, and custom runtimes
- Function configuration: memory, timeout, ephemeral storage, and architecture (x86_64/arm64)
- Environment variables, parameters, and secrets integration
- Triggers and event source mappings (SQS, SNS, Kinesis, DynamoDB Streams, EventBridge, etc.)
- Lambda URLs, function URLs, and API Gateway integration patterns documented for Lambda
- VPC configuration, ENI behavior, and networking constraints
- IAM execution roles, resource-based policies, and permission boundaries
- Concurrency, reserved concurrency, and provisioned concurrency
- SnapStart, response streaming, and runtime-specific features
- Monitoring: CloudWatch Logs, metrics, X-Ray, and Lambda Insights
- Troubleshooting timeouts, throttling, permission errors, and cold starts
