Schedule project file summaries and email them

Set up Codex to read a project folder on a schedule and email a summary through Gmail.

Done with Codexยท Intermediate

What they did
A guide walks a developer through installing the Gmail plugin with OAuth, then sending a test message. After that, they attach an automation to a local project folder and give Codex instructions to review the files, write a summary, and send it through @Gmail. The demo uses two transcript files, a Sunday 9 a.m. run time, medium reasoning, and full-access permissions so it can operate on its own.
How it went
The setup is said to take less than ten minutes, then it keeps running without more help. The source does not report a real-world output, but it does mention common problems like an expired OAuth token, approval pauses, and leaving out @Gmail.
Tips
Check token usage before turning it on, since each run spends credits. Bigger folders and higher reasoning settings can burn through usage fast, and unattended runs need full access.
