How to track coding agents and approve them from iPhone with Coucou

See agent progress on your iPhone Lock Screen and approve permissions with Face ID when you step away from your Mac.

Credentials. Remote approvals from a phone can start actions on your Mac, so only approve requests you recognize and keep Face ID enabled.

Who it is forA developer who starts long agent runs on a Mac and leaves the desk while they work.

The problemAgents stall on permission prompts while the developer is away, and there is no way to see or approve them from a phone.

The outcomeThe Mac session moves to the iPhone Lock Screen and Dynamic Island, and each permission can be approved with Face ID.

What you need first

  • A Mac, since the notch app and most features are macOS only
  • Download the Coucou app from the releases page linked in the README
  • An AI coding agent such as Claude Code, Codex, Cursor or Gemini CLI
  • Your own API keys for any cloud provider you plan to use, stored in the macOS Keychain
  • An iPhone with the Coucou iPhone app, only for the phone features

Steps

  1. Set up Coucou on the Mac and sign in with the iCloud account used by the iPhone app.
  2. Install the Coucou iPhone app and allow notifications.
  3. Start an agent session on the Mac, such as Codex, Cursor or Gemini CLI.
  4. Lock the Mac and watch the agent state in the Live Activity on the iPhone.
  5. Tap Allow or Deny from the Lock Screen and confirm with Face ID.

Prompt for your agent

Using the Louis-CFM/coucou repo, set up the Coucou Mac app and iPhone app so that a Codex session on <target Mac> shows as a Live Activity on <target iPhone>. Expected output: the agent state appears on the Lock Screen, and an Allow tap is confirmed with Face ID. Verify that the Mac applies only the decision for the request it is waiting on.

Caveat. The README does not list the iPhone app install route or the setup for iCloud sync, so those steps need to be checked in the repo before use.
