I'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.
