What Hacker News says
5 sourcesThere's a cool research project https://github.com/exoharness/exo that is designed specifically as a self-modifying harness, so architecturally it separates things in a way that makes it a lot harder for the agent to break itself when modifying itself. It looks pretty neat. Saw the author do an interview on a podcast explaining it.

3 points · Open discussionI'm just exhausted. So I've today now learned about four new harness:
https://github.com/exoharness/exo/
https://github.com/laude-institute/headlong
https://github.com/microsoft/agent-lightning
and now https://github.com/PrimeIntellect-ai/prime-agent
Of course the don't have exactly the same scopes but they are in general all about persistent memory and / or continous agent loops. Like I miss those times where only once a week a new js framework was promoted.
