AWS Emulator Was Written 100% by Thousands of Autonomous AI Agents

AWS released AWS Emulator, a local emulator for building and testing AWS applications on your machine — with every line of code written by thousands of autonomous AI agents, open-sourced under CC0 on GitHub and continuously updated.
Sr. Principal Engineer Matthew Goldberg's writeup covers:
- Agent failures stem from lack of competence, not malintent; the team's "coloring book" metaphor: give agents well-defined boundaries so the larger picture comes together
- Thousands of autonomous agents write tests, find bugs, and fix code without human review
- A landmark case of agents shipping a full production-grade project
The key insight is how to organize swarm-style agent development — directly relevant for teams orchestrating coding agents at scale.
