I ran /insights on Claude Code and it said code review was my most requested activity. I turned it into a skill that autodiscovers the project's structure and launches a huge matrix of parallel critic agents, each focusing on one specific area of the codebase and a quality like correctness, maintainability, security, etc. Supports file system style journaling to deal with subscription usage limits and interruptions.
Took maybe a few hours to fine tune this and then I applied it to all of my projects, and it's actually absurd how productive it is. This is basically an infinite GitHub issue generator. I run it and then start checking off the items in order to definitely improve the status quo. Review again, fix again. Just loop this until zero issues found. The only question is whether to fix the issues myself or tell Claude to do it. I still do it myself in the projects I really care about.
