Mindwalk - Replay coding-agent sessions on a 3D map of your codebase
Show HN: Mindwalk – Replay coding-agent sessions on a 3D map of your codebase
Mindwalk transforms opaque coding-agent logs into an immersive 3D visualization, allowing developers to see exactly how AI agents like Claude Code and Codex navigate their repositories. Instead of parsing raw JSONL files, users can watch sessions replay as light moving through a 'night map' of their code, instantly revealing search paths, file edits, and exploration patterns. This fully local Go binary ensures privacy while offering powerful tree and terrain views to audit agent behavior, making complex AI interactions intuitive and visually clear for better code review and debugging.
Draw the repository as a night map, and play the session back as light moving through it: where the agent searched, read, and edited, the map glows — everything else stays dark.

Hey OP, this is absolutely awesome and I am very much on your creative wavelength! I'd love to get in contact with you if you have a moment, as I've built an adjacent 3D visualizer that might complement the rendering portion of your system by providing actual glyph-level rendering of each file instead of block-based representations (glyph3d.dev). I have a similar "trace" feature that shows files pre/post edit from CC at the moment, so there is some definitely interesting overlap.
Well done creating A Cool Thing!

A lot of people want a use case. One I think might be cool is some kind of spatial/represented comparison: let's see how two different models interact with the codebase (for the same problem), what they touched, and what they did. Or the same model, but averaged across 100 runs, so we can see how much variance there really is per task. Something along those lines sounds interesting to me.

This is really cool! I’m becoming convinced the optimal UI to engage with agents, long term is going to be something spatial. No idea shape that even takes, though I really feel what you’ve made might be Xerox PARC days in terms of metaphor maturity, but there’s some real new seeds of “obvious in retrospect” ideas here. Thanks for conceiving of and building this!

This reminds me of that community epsiode where they get the VR system and the dean has to walk through a maze, climb up several things so that they can go to a filing cabinet and then retrive a file. Yes, its cool to see and watch but it seems to be adding more friction than reducing it. Like who is going to spend that much time watching what their agents did when there are far quicker and efficient ways of scanning through changes and organizing code with better ergonomics?

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.
