Show HN: I built an AI coding agent 50% cheaper than Claude Code (same prompts)

I built vix, an AI coding agent that uses a virtual filesystem to minify source code so the LLM always works in the minified space, and the concept of stem agents that allows for optimal cache hits in plan mode.

I used the same prompts and same model than claude code, and run both vix and claude code over 7 life like benchmarks, ran 5 times each. The results are that vix is 50% cheaper and 40% faster than claude code. I shared all the plans and the diffs in the repo so you can compare the planning and execution quality by yourself (similar in my opinion).

I wonder how that compare to harness methods like MAKER https://www.cognizant.com/us/en/ai-lab/blog/maker

I don't think so, you just forgot to add the remote server address. If you run `system "git", "ls-remote", " --upload-pack=$(touch hello) git@github.com:torvalds/linux.git", "HEAD"` it will fetch the remote server but still create the file on the local machine.

You explained what this option is, I was asking why.

I had the same reaction as you... it looks like the vulnerability is coming from git, that's a very dangerous behavior.

I still don't get why the --upload-pack option execute its content... Seems pretty dangerous to me. How did you find that out?
