Wrapper > Model Harness > Personal Harness > Org-level Harness

This is correct, I think a number of people on the tl didn’t read past the title and made inferences and comparisons that are just wrong and then use it as an opportunity to take cheap shots. This is not a “feature” like some crappy Slack bot and it’s certainly not a Claw, though it has aspects of it. It is an org-level harness. The difference will become clearer over time.

Users agree with Karpathy's clarification on AI harnesses because distinguishing a basic wrapper from a proper abstraction is the hardest part to explain.

Well since I keep up with the RL env market: Anthropic really did tons of Slack RL

(Didn’t really get the obsession at the time, but yeah, it’s not slack being solved but Claude absorbing the most convenient tooling)

The jump from personal to org-level is where most teams stall. Personal harnesses optimize for one person's workflow. Org-level harnesses have to handle conflicting preferences, audit requirements, and permissions across roles. In regulated industries that org-level layer isn't optional - it's the product. What's the main failure mode you see teams hit at that transition?

@GregKamradt wait til @karpathy learns your entire organization trello board can be read via a json file. Built in tagging in any social media channel agents run in sandbox and then update via trello cards. You could pull context as well

@GregKamradt That chain tracks. The gap between a wrapper and a proper abstraction is always the hardest part to explain.
