diagnose

Inspect recent ECS task failures and CloudWatch logs for the current project.

What it does

Saves you from digging through the AWS console by finding the most recently stopped ECS task for this project and showing why it stopped plus the failing container’s recent log events (up to 50 lines).
Resolves its inputs automatically: the AWS region from AWS_REGION, falling back to region in terraform/main.tf (default us-east-2); the cluster (<project-name>-cluster, overridable via ECS_CLUSTER); and the log group (/ecs/<project-name>, overridable via ECS_LOG_GROUP).
Lists up to 10 recent stopped tasks, describes up to 5 of them, and diagnoses the most recently stopped one: stopped reason, failing container name, exit code, and container reason.
Makes no changes to your infrastructure; it is read-only. Prints a healthy message and exits when no stopped tasks exist.
On expired AWS credentials, points you to aws sso login / aws configure and the AWS credentials guide, then exits with code 1 instead of throwing.
Emits a diagnose_run telemetry event recording success and whether the service was healthy.

npx deploy-stack diagnose
npx deploy-stack wtf

wtf is an alias for diagnose.

This command accepts no CLI flags. Region, cluster, and log group are resolved as described above, not from flags.
