Jason Liu demonstrates the advanced capabilities of Codex by describing how it can be prompted to create a pull request, monitor its tests, and then send a Slack DM to a specific contact upon successful completion. This showcases the AI's ability to handle complex, multi-step workflows.
“Um, for example, if I'm working on some code, I might just say, great, make a pull request. And then check in on this pull request and once all the tests are green, I want you to DM Andrew on slack with the link to the pull request and the preview URL.”
“Right? It can do that quite well. But the chief of staff thread becomes it reads 40 emails and, you know, a hundred slack messages. I want to be a little bit a little bit more surgical on how things are handled.”
