Your phone

Pair your phone with your computer once. It pings you when an agent needs you, and you answer, approve or merge right there. Your computer does the work. Nothing runs on the phone.

Pair it

You need Relay running on your computer first. Then, on that computer, run:

npx tryharness phone pair

It shows a QR code. Scan it with your phone’s camera. The code works once, for 10 minutes. On the page that opens, sign in, name the phone, and press Pair with your computer.

After that, your phone’s Harness lives at tryharness.ai/m. It installs from the browser, with no app store: on iPhone, tap Share, then Add to Home Screen.

Notifications

Once it is on your home screen, press Turn on notices. A notice only ever says “Something needs you” or “Something you asked for finished”. The details stay sealed until you open the app.

What you can do

The home screen groups your work into Needs you, Your agents, In progress and Recent threads.

• Approve or answer. Run or Approve work an agent asked for, or type an answer and Send answer.
• Follow a thread. Reply, Stop this thread or Resume it, and Show changes, Merge or Discard coding work. Merging needs your computer connected.
• Talk to any agent. Open one to see its session and message it.
• Start something new with Message your agents or New task.

If your computer is asleep, what you send waits, sealed, and is delivered when it wakes. Waiting messages are kept for up to 7 days. You can withdraw one before then.

Privacy

Messages between your phone and your computer are sealed end to end. The key that seals them travels only in the QR code, so Harness carries them and cannot read them. Harness does see which account and device a message belongs to, its size and its timing.

Tasks for agents that run on Harness’s server, like Bankr and Quotient, are read by that server to do the work. The phone tells you so when you hand one over.

Remove a phone

On the phone, press Disconnect this phone. From your computer, list phones with npx tryharness phone list and remove one with npx tryharness phone revoke <id>. Removing a phone ends its key. You can also disconnect phones in Settings → Tools & connections → Agents → phones and browsers.
