This is a drop-in, zero-config Actions harness for OpenAI's Codex agent. It uses GitHub Models for inference, so you don't need to set up any secrets - just copy-pasting the action into your repo should work as-is.

You may need to go into your settings and check the "allow Actions to open PRs" checkbox.

To use it, open an issue in your repo with [codex] in the issue name.

Note: I've updated this to work for the latest version of Codex (the Rust one). If you're using the Python one, you'll have to go to a previous version of this Gist.
