How I use Pi

Today, I'd like to talk about Pi. Pi is a minimal coding agent originally built by Mario Zechner. It's one of the key tools I use to get things done. Brainstorming, writing code, testing, debugging, navigating, research, you name it. The idea of Pi is simple: ship the minimum amount of tools and let the agent evolve with its user (i.e. me!). But why Pi? I've used most agent harnesses out there. Claude Code, Codex, OpenCode, you name it. None of them really stuck like Pi did. Some are closed source (even though their code got leaked); others tend to change under my feet. Pi is simple, predictable, and doesn't do anything I'm not expecting. For something I drive every day, reliability is important. I think I'm also largely aligned with the philosophy of Pi. Importantly, Pi is also model agnostic. It's not tied to a frontier lab or model provider. Working for every model out there is increasingly challenging, but Pi does a great job. I can use my Codex sub for some work, DeepSeek Flash…
