I use https://pi.dev/ which works fine out of the box but is fairly minimal and intended to be customized. There are many extensions. OpenCode or oh-my-pi might make more sense if you just want a batteries-included agent. You can also make Claude Code work with other models without too much work, but I think that's asking for headaches. - Source: Hacker News / 4 days ago
I divided the project into three parts, inspired by Tau's "brain, environment, face" split, and by Mario Zechner's pi:. - Source: dev.to / 6 days ago
Maybe you should try using Pi [0] if you care a lot about owning your harness and making sure you're in control of what goes into your system prompt and context? [0]: https://pi.dev. - Source: Hacker News / 13 days ago
An extensible LLM agent (such as https://pi.dev/ or maybe hermes) written in common lisp could be interesting. Conditions and restarts and general debugging and repair of the live system, fast startup, native execution speeds, ability to add or replace or modify core functionality on the fly, solid multi-threading support, dynamic introspection including documentation, CLOS and multiple dispatch, saved images. - Source: Hacker News / 14 days ago
Over one night I rebuilt both halves of that sentence on pi โ an open, npm-distributed, forkable agent runtime โ mostly to find out how much of my harness was discipline and how much was one host's shape. Two public repos came out of it: pi-eval for the proof half, and pi-gates for the irreversibility half. - Source: dev.to / 15 days ago
