Why they built it
Simple LLM chatbots wired to AWS CLI failed in production by running wrong commands, forgetting context, and lacking failure recovery.
What worked
Reflection pattern self-corrected ~80% of transient failures; real-time streaming via SSE improved UX; state persistence with DynamoDB checkpoints enabled session resumption.
What broke or was painful
Overlapping tools caused debugging issues; AWS API rate limits during discovery; fragile cron scripts for shutdowns.
The result
Monthly cost analysis reduced from 2.5 hours to 4 minutes; Lambda audit from 45 minutes to 6 minutes; S3 sweep from 1 hour to 3 minutes.
