Show HN: Valknut – static analysis to tame agent tech debt

https://github.com/sibyllinesoft/valknut
2•CuriouslyC•10h ago
Hi y'all,

In my work to reduce the amount of time I spend in the agentic development loop, I observed that code structure was one of the biggest determinants in agent task success. Ironically, agents aren't good at structuring code for their own consumption, so left to their own devices purely vibe-coded projects will tend towards dumpster fire status.

Agents aren't great at refactoring out of the box either, so rather than resign myself to babysitting refactors to maintain agent performance, I wrote a tool to put agents on rails while refactoring.

Another big problem I encountered trying to remove myself from the loop was knowing where to spend my time efficiently when I did dive into the codebase. To combat this I implemented a html report that simplifies identifying high level problem. In many cases you can click from an issue in the report directly to the code via VS Code links.

I hope you find this tool as useful as I have, I'm working on it actively so I'm happy to field feature requests.
