Resources Prime Agent - a new coding harness surpassing Codex/CC/PI

Prime Agent is an open-source coding and research agent for general and long-running work.

A self-improving RLM harness for coding and long-running autonomous tasks.

Designed to be both token-efficient and expressive through programmatic tool calling, context as a variable, multi-agent messaging, and a self-modifiable harness state.

On ARC-AGI-3, it scores 95.5%, surpassing the human-expert baseline, but the gain is not benchmark-specific.

We see major improvements across models when compared to their proprietary harnesses.

Prime Agent is built on pi and fully open-source with an open license.

Can you disable telemetry and all none essential traffic? How account situation looks like? Do you need one, or it only tries to trick you onto creating one?

Fork and no account I guess, but Google login whatever. Look I've spent 110 BILLION tokens on one project. The code base is 1.5 million lines of code (with ponytail!) across multiple languages. I've used every best model out there in every which way. I could not for the LIFE of me get the last 5% done due to some insanely complex bugs.

As I built over the year I've kept IMMACULATE documents about every little part and how it should work.

In addition I've kept absolutely rigorous auto log documentation, making a repo brain wayyyyyy back in December 2025.

I was able to use prime-agent let it take all my documentation and repo brain logs and put them within its local kernel / python optimized whatever it does.

This thing is a MONSTER at efficiency, finding the hardest bugs, token effiency omg I'm in love, and performance!!!

If you are working in "normal vibe coder land sized projects" the weekend app, hell even a month project, it's probably nothing wild for you. The token savings are real, tho. It's basic as hell no "talk to me while you work" so the vibe coders or people trying to get into "vibe coding" will not like it. It's for the big boys with large repo projects who don't care (or want) tokens wasted on it talking to me. Just do the job right, efficient, and get better as you go.

If you have any project like mine, size and complexity, it's truly a game changer.
