OpenAI Doubled Codex Limits — Only Days Left (+ Santa Mode 🎅)

OpenAI doubled Codex rate limits through the end of the year — and gave us a Santa-themed model that sprinkles your code with holiday fun. I show you how to use the new model, and put both to work on a security audit I've been avoiding. I had a React security patch sitting in my inbox for weeks. Instead of just applying it, I asked Santa Codex to audit my entire Bookmarker web project. It found the React issue (eventually), plus a bunch of other problems I didn't even know were there: hardcoded secrets, client-side credential storage, leftover OAuth artifacts from when I switched auth methods. The kind of technical debt that builds up when you let AI write your code but never actually look at it yourself. The Santa personality is genuinely fun — it calls security issues "coal-grade risks" and tells you your "sleigh is behind the North Pole conveyor belt" when you need to pull from upstream. Not overwhelming, just enough to make the terminal feel festive. I also asked it to add a holiday theme to my site. It built a feature-flagged overlay with snowflakes, garland, and hot cocoa — complete with an expiration date so it turns itself off after the holidays. Exactly what I asked for, zero configuration needed. If you've been putting off housekeeping tasks or have a bigger project you want to tackle, now's the time. Double token usage through the end of the year.
