I built a new feature for my blog entirely by voice in Codex Desktop while cooking dinner.

Usually a feature is built at a keyboard and screen. Here the task was given by voice, and Codex Desktop wrote the code while his hands were busy cooking.
For developers, the key signal is that a coding agent works without hands on the monitor. The author walks through the process on his blog; see the original source.
Next, we'll see whether other authors repeat this scenario: one tweet is not a trend yet.
