Headlong: A Microharness for Persistent Agents

Very fascinating, super interesting engineering. Although i do find it very funny how they just bypass a massive vulnerability, basically zero data isolation (even between good actors, let alone bad ones) with 3 sentences. Only in the llm space you can slap a massive limitation like this in the middle of the article and continue like nothing happened

> Whatever anyone tells Audel becomes part of the single experience that every other conversation draws on. In practice, Audel is bad at keeping secrets. Ask it what it’s been working on with someone else and it will often just tell you, even though we’ve asked it not to. We also haven’t studied what happens when two people give conflicting instructions. For now, we assume anything you tell Audel is shared with everyone on the team.

Sub Question : IS there a real successful agent product today that uses a library for harness(like langgraph etc)? Building our own worked for us. Works with our components(postgres, events ...) and scales naturally with our system.

Are there any objective metrics/ benchmarks that people test harnesses by?

There are just so many now that it's hard to personally test them all or just trust the vibes.

The Googlers must be vague posting about something internal.

It buries the lede. Prime Agent sounds like a very cool project.

Wow. So, be nice or I'll replace you with a very large shell script?
