What it does

Reason Agent by Reason Machines is the autonomous AI software engineer and cloud coding agent. Connect GitHub, assign issues, and ship evidence-backed pull requests on autopilot.

In the new era of harnesses, moving fast on the best way to utilize new models and their capabilities is everything. Our principle is minimal and maximal harnesses: minimal so we stay the fastest to act, and maximal so we use frontier models for their strengths. The Rust ledger is ready for review. Amounts are fixed-point now, so they keep the C++ decimal rules, and every fixture matches the old output byte for byte.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
