Codex is mind-blowingly good at writing #elixirlang. I can spend hours iterating on system design with it, optimizing for simplicity and observability. Once that clicks, the result is a system that is easy to understand and easy to debug, for both me and Codex.

For observability, I record and correlate every important session. Through Tidewave, codex can use that context to debug itself. I even have it build custom UIs so I can inspect everything in real time.

One of #elixirlang’s superpowers is how easy it is to reason about: its functional model keeps complexity in check, built-in observability is excellent, and Tidewave pushes it even further.
