Over the past three months, a team of experienced, like-minded engineers and I have been building something really cool within Amazon Bedrock. While I’m pretty excited about what we are building, there is another unique thing about our team  – most of our code is written by AI agents such as Amazon Q or Kiro. Before you roll your eyes: no, we’re not vibe coding. I don’t believe that’s the right way to build robust software.

Instead, we use an approach where a human and AI agent collaborate to produce the code changes. For our team, every commit has an engineer’s name attached to it, and that engineer ultimately needs to review and stand behind the code. We use steering rules to setup constraints for how the AI agent should operate within our codebase, and writing in Rust has been a great benefit. Rust compiler is famous for focusing on correctness and safety, catching many problems at compile time and providing helpful error messages that help the agent iterate. As a juxtaposition to vibe coding, I prefer the term “agentic coding.” Much less exciting but in our industry boring is usually good. — Read More
