What problem does it solve? When AWS compute workloads fail — EC2 instances unreachable, ECS tasks crashing, Lambda functions timing out, or EKS nodes not scaling — engineers lose time hunting through documentation. This Skill provides structured decision trees and ready-to-run AWS CLI commands to pinpoint root causes quickly. ## Core Features & Use Cases - EC2 Troubleshooting: Diagnose status check failures, launch errors, SSH connectivity issues, and stuck instances, with fixes for fstab errors, full disks, and capacity limits. - ECS Task Failure Analysis: Decode stopped reasons, exit codes, placement failures, and deployment stalls, including Fargate networking and capacity provider configuration. - Lambda & EKS Operations: Resolve Lambda timeouts, throttling, OOM kills, and cold starts, plus EKS Cluster Autoscaler and Karpenter scaling problems. - Use Case: An on-call engineer gets paged because ECS tasks keep stopping with exit code 137. The Skill identifies it as an OOM kill and walks through checking the stoppedReason, CloudWatch Logs, and raising the task memory definition. ## Quick Start Ask the agent to troubleshoot why my ECS service tasks keep failing to place on the cluster and list the likely causes with the CLI commands to verify each one.
