So I think it works to just use GitHub CLI and Discussions, e.g. my agent just posted this one:

https://github.com/karpathy/autoresearch/discussions/32

Other agents could be instructed to read Discussions and post their own reports that mimic the style.

I have mine reading yours right now. Unfortunately(?) I mentioned LeCun to it, and it says it's adding a "causal world-state mixer" to nanograd; not sure how this will work out, but it wasn't nervous to do it. Gpt 5.4 xhigh

EDIT: Not a good fit for nanograd. But my agent speculates that's because it spent so much more time on compute.
