I started Valknut (https://github.com/sibyllinesoft/valknut) when I saw the writing on the wall regarding Agent code structure/abstractions/etc being a limiting factor in the ability to autonomously build projects. My experience was that good linters helped, but it wasn't enough, you needed to be able to enforce information-theoretic related organizing principles in addition to file/function LOC and local complexity metrics to guide agents on how to structure code.

Originally I tried to walk the line between improved agent performance and human readability, but current models are so good I don't think human readability matters much, though at a high level, being able to grok the overall folder structure still matters. I've got my hands full polishing a demo for my game, but I intend to revisit Valknut by crafting an eval set that lets me calculate the difference in agent token consumption and task failure rate between ~isomorphic codebase structures. This will let me loop agents to discover organizing policies that improve them.

Truthfully though, with today's models I don't think this sort of codebase optimization is likely to have much impact below 250k-300k LoC projects, and it probably won't be a decisive win till you're near 1M. Also, the shelf life of a product like this isn't infinite as each generation of models pushes those numbers up while also having new policy preferences that require re-evaluating existing policies.
