AWS Weekend Agent Challenge: Daybreak

AWS Weekend Agent Challenge: Daybreak

Short summary

Daybreak is a serverless AI agent that inventories all your GitHub repos every morning at 6 AM and emails a brief with live/quiet/unlicensed counts plus three actionable nudges. Built on AWS Lambda, EventBridge Scheduler, Bedrock Nova Lite, and SES with zero third-party dependencies. Key lessons include Nova's cross-region inference profile requirement and the importance of deterministic structure with generated narrative.

  • •Serverless agent reads GitHub repos and emails a daily brief via Bedrock Nova + SES
  • •Architecture uses EventBridge Scheduler, Lambda, and SAM with least-privilege IAM
  • •Deterministic counts computed in Python; Nova only generates narrative and nudges

Generated with AI, which can make mistakes.
