At 3:17 AM last Tuesday, my payment-api ECS service entered a terminal failure loop. 7,279 failed tasks since August 13th. The health check expected /api/health but the container only served static content. Every 60 seconds, ECS killed the task and replaced it. Burning compute the entire time.
No alarm fired. I never set one up. No PagerDuty page. No Slack alert. Just a service churning through resources that nobody was watching.
I slept through the whole thing. And woke up to a solved problem.
Not because I got lucky. Because my Kiro Crew agent was awake. It spawned 5 parallel investigations, called AWS DevOps Agent for a health assessment, found the root cause across ECS, CodeBuild, CodePipeline, and Lambda, and flagged everything with severity-prioritized fixes. By 3:24 AM, done.
This is Part 6 of my Kiro Crew series. Parts 1 to 5 showed what Crew can do: orchestrate agents, run cron jobs, enforce security, build custom apps. This one shows what happens when you connect it to AWS's production intelligence engine.
