[Feature request] Notification when Codex web finishes a task

Dear development team,

You’ve made Codex (speaking of web version) feel more user-friendly. I need a “task complete” notification. When I run different jobs in parallel, I often miss a finished task for 15+ minutes; it usually still needs more passes. That delay between iterations slows me down. I want to focus on other work instead of polling or watching Codex run.

Request: Opt-in completion alerts (desktop push, email or in-app). Any notification is better than none. What would block shipping this?

Codex has recently added a terminal bell on some recent update. I hear a little “beemp” sound on Ubuntu 25.10. Not as ideal as a notification since I don’t know which terminal finished. But already a huge improvement. I then learned that tmux highlights tabs which have had a bell, so you could find which one finished, but only if all tabs fit in the terminal. Tested on codex-cli 0.93.0.

OK, it is now possible in Codex CLI with hooks Hooks – Codex | OpenAI Developers , tested on codex-cli 0.125.0 Ubuntu 25.10:

~/.codex/config.toml

[features]
codex_hooks = true

[[hooks.Stop]]
[[hooks.Stop.hooks]]
type = "command"
command = 'notify-send "done"'
