Claude Sonnet 4.5 (Claude Code) wrote most of it with ChatGPT 5 (Codex) reviewing and Claude addressing issues in each review. Codex wrote the last 10% or so when Claude kept getting stuck.
I did not write a single line of code but carefully shepherded AI over the course of several days and kept it on the straight and narrow.
- AI: I need to keep track of variables moving across registers. This is too hard, let’s go shopping…
- Me: Hey, don’t any no shortcuts!
My work was just directing, shaping, cajoling and reviewing.
