open-artifacts

open-artifacts is a small plugin for Codex that takes inspiration from Claude’s excellent artifact system. It gives Codex a structured way to create HTML pages that you can open in your browser and comment on directly. You can attach a comment to any element, and Codex can read your feedback

A sample Sunday itinerary artifact viewed on mobile — An artifact, a comment, and the private library. Tap a screenshot for a closer look

The same artifact with a comment asking for a rainy-day option — An artifact, a comment, and the private library. Tap a screenshot for a closer look

I use this for giving my input on large plans that benefit from visual elements, such as proposed designs. Codex might attach a dozen screenshots showing proposed changes to a website, for example, and I can comment on each directly. Codex can then retrieve those comments, apply my feedback, or revise the artifact for another round of review

It’s built to work with TailScale, also supports ChatGPT’s Sites, and should work well with other harnesses (though that’s untested)
