How OpenAI’s DevEx lead uses Codex as a workday chief of staff
Jason, OpenAI’s DevEx lead, says he uses Codex to build a daily “heartbeat” for Slack, email, and Linear. He started with simple daily overviews, then iterated on preferences: first adding links, then connecting Linear, and now having Codex pre-draft Slack replies and emails.
In the episode, he also shows a broader agent workflow:
- Turn past sessions into reusable skills
- Ask it to learn his writing style from a week of Slack history
- Give long-running projects verifiable goals
The core idea: the hard part is not issuing prompts, but learning what you dislike, encoding that into instructions, and letting the AI handle the routine follow-up.
