[ANN] ychr is on Hackage

The software package ychr has been released on Hackage, with its author emphasizing that users should review the code before trusting it. The author states that every change was reviewed by multiple independent AI agents from different companies, and that they perform regular adversarial QA tests, both manual and agent-driven.

Same as any other software you install: you don’t know unless you review the whole code base.

Regarding this particular project, I can give you a little more context, so you can decide yourself whether to trust the software or not:

  • I reviewed a good part of the code, focusing on the parts that I deemed more important, and skimming over the rest.
  • Every single change has been reviewed by multiple independent AI agents, also by models of different companies.
  • I perform regular adversarial QA tests, both manual and agent-driven.
  • I am familiar with the domain and would be able to rewrite the same compiler without AI (given enough time). If the code contained something blatantly anomalous I think I would spot it quickly.
