What problem does it solve? When an application starts failing, engineers often waste hours manually digging through scattered CloudWatch log groups trying to find error patterns and root causes. This Skill automates log group discovery, error pattern analysis, and root cause identification to produce a prioritized remediation plan. ## Core Features & Use Cases - Log Group Discovery: Automatically finds CloudWatch log groups related to an application name across Lambda, API Gateway, ECS, and custom log groups. - Error Pattern Analysis: Runs CloudWatch Logs Insights queries to detect exceptions, stack traces, timeouts, and authentication failures, then categorizes them by type and frequency. - Root Cause & Remediation Report: Generates a structured report with prioritized root causes, immediate/short-term/long-term fixes, and monitoring recommendations. - Use Case: Your payment-service in us-west-2 is returning errors. Provide the application name and region, and receive a report showing connection pool exhaustion as the primary cause with specific code fixes and CloudWatch alarm recommendations. ## Quick Start Troubleshoot my application payment-service in region us-west-2 by analyzing its CloudWatch logs from the last 4 hours.
