From Lazar Jovanovic's 4x4 debugging sequence
What was said about Repo Mix
Pack the codebase into one file for an outside AI review. Lazar Jovanovic uses Repo Mix to compress an entire codebase into a single file. He uploads it to Claude or ChatGPT along with the logs, like hiring an external consultant. He calls it an older method for outside review.
It is step three of his 4x4 debugging sequence, as an alternative to exporting to GitHub and having a tool like Codex diagnose the problem. In that step the outside model only diagnoses and is not allowed to edit. Before reaching it, he first tries the tool's built-in fix button, then adds console logs and pastes the output into the chat, which he says is enough 99% of the time. If the outside review fails, the fourth step is to revert, rethink the prompt, take a break and retry.
