- Reported result
- A recurring email-to-calendar reconciliation agent and a successful audible iPhone notification test are reported by the poster. Checks run every ten minutes while the Mac is awake and Codex is running. The initial historical review was still underway; no reduction in future missed appointments is established.
- Human involvement
- The poster granted Gmail access, requested the investigation and helped inspect phone settings and test actual notifications. They disabled automatic Focus activation without establishing it as the cause. Departure details still need to be supplied for appointments away from home.

How the agent did it
- The poster gave the ChatGPT desktop app Gmail access and asked AI to reconstruct the missed appearance from correspondence.
- The reconstruction reported by the poster identified a canceled calendar invitation followed by an ordinary confirmation email without a replacement invitation.
- The poster and Codex set up a recurring agent to reconcile confirmed email obligations with the existing iCloud calendar.
After missing an appearance, @davepl1968 asked AI to reconstruct the email trail. The account describes a preparation-call mix-up and a canceled calendar invitation followed by an ordinary confirmation email. The commitment remained, but the replacement message did not restore the calendar reminder.
The poster used the ChatGPT desktop app with Gmail access and describes asking Codex to investigate. A recurring agent was then set up to compare confirmed email obligations with the existing iCloud calendar. According to the workflow reported by the poster, it reads whole conversations, accounts for changes and cancellations, adds missing personal entries, attaches the source email and meeting link, flags contradictions and checks reminders.
Testing went beyond checking that an event existed. Early test events reached the iPhone without notifications. The poster and AI inspected alarms, synchronization, notification and sound settings, and Focus configuration. Automatic Focus activation was disabled, but the post explicitly says they could not prove it caused the earlier failures. A notification that appeared on the phone and made a sound is reported by the poster.
The agent checks every ten minutes while the Mac is awake and Codex is running. The initial historical review was still underway, and appointments away from home still needed departure details. This is a reported setup and phone sound test, not evidence that future missed commitments have been eliminated.
Who it's for: people whose confirmed obligations are scattered across email threads and calendar updates.

About this account
The recurring agent reads conversation context rather than converting every date mention into an event. Its reported remit includes reconciling changes and cancellations, adding missing personal entries, flagging contradictions and checking reminders. The post does not establish long-term reliability.

The bio describes Windows component work and discloses no affiliation with the agent vendor; that absence is not proof of independence.
