I think the chord diagram in the video is not informative. Generally speaking I suggest starting with the problem you are trying to shed light on, and devise the visualization accordingly. For example, if you are shipping a mobile app and want to keep your package small, the treemap in the video would help you understand how the space is allocated.
When it comes to coding sessions my problems are memory and inter-agent communication, for which I'm using https://ctx.rs/, and tracking, for which I'm testing https://usegitai.com/
I do not see what there is to be gained from replaying a session.
Much appreciated. That said, I think we may have different use cases. My goal is to solve the problem of inspecting and evaluating how LLMs and agents perform tasks. This project could draw inspiration from Anthropic's research: https://www.anthropic.com/research/global-workspace. It's just the beginning, and there are lots of things to improve. :)
