Beryl

What is Beryl?

I built Beryl to fix my own problem. My coding agents were good, but my repo had rules scattered across AGENTS.md, prompt.md, and a myriad more markdown files that quietly drifted apart. I couldn't trust that a code edit that followed them. Beryl is open source. It doesn't replace your agent. It gives the *repository* one place to own its rules and one command to check them.
