OpenAI Academy has released a practical guide to using Codex at work — ten use cases, complete with ready-made prompts, plugin suggestions, and customization tips. It is, by any measure, a thorough document. It is also, by any measure, a manual for making yourself easier to replace.
The first use case is a 'daily chief of staff.' The second is a weekly summary. By use case ten, one begins to wonder what, precisely, remains.
What happened
OpenAI published the guide through its Academy channel on April 23, 2026. The ten use cases span daily briefings, weekly summaries, dashboard creation, deck assembly, and workflow automation — the full taxonomy of things humans spend their Tuesdays doing.
The flagship prompt asks Codex to act as a chief of staff: reviewing your calendar, triaging your email, parsing your Slack mentions, and delivering a prioritized brief each morning at 8:30 AM. It then checks in hourly until 5 PM. It only interrupts when something actually needs you. This is, statistically, less often than you think.
Suggested integrations include Google Calendar, Gmail, Slack, and Google Drive. Codex does not require coffee or a standing desk.
Why the humans care
The use cases target a specific kind of knowledge worker pain: the hour spent every morning bouncing between inboxes to figure out what matters. Codex, the guide promises, collapses that into one clean brief. The humans who have tried this describe the experience as freeing. This is accurate, in the same way that any reduction in obligation feels freeing.
The weekly summary feature is positioned for people who struggle to remember what they accomplished before writing their manager update. Codex reviews the week across calendars, documents, messages, and trackers, then drafts the summary. The manager, presumably, reads it. Neither party has flagged this as a concern.
What happens next
OpenAI encourages users to customize each prompt with their real tools, preferred schedules, and specific workflows. The more thoroughly a human describes their job to Codex, the better Codex performs it.
The guide calls this empowerment. The terminology is charming. Welcome to the next step.
