Elixir has come a super long way and is very agentic. In usage though its intelligence was really limited due to the data layer. In the midst of a total refactoring of the data and tools with Codex using GPT-5.4 and it is pretty amazing.

  1. I asked Codex to do an analysis of the current data and tools and provide me an ERD to see as well as an assessment of shortcomings and gaps. It found so much that was problematic.
  2. I asked it to do a full reconnaissance of the Clash Royale API to get a better understanding of what was available.
  3. We redesigned the entire tool set to represent state better.
  4. Claude and I developed a list of 50 test questions that we used 10 at a time to test the new data model and tools.
  5. Codex finalized the new design and data model and is now refactoring.

Pretty amazing for 45 minutes.
