We made a 31-second promo to say one thing: your phone is the best remote for your agent

The DeepSeek Phone Harness promo is live. 31 seconds, 8 shots, one message: your phone controls your computer.

Watch it first

๐ŸŽฌ DeepSeek Phone Harness ยท 31s promo (grab https://github.com/2903077918-lgtm/DeepSeek-phone-harness/releases/download/v0.4.0/promo.mp4 (with BGM) / https://github.com/2903077918-lgtm/DeepSeek-phone-harness/releases/download/v0.4.0/promo-nobgm.mp4 (no BGM, SFX kept) from the repo)

In the dark, a phone screen glows gold. Messages type out on it. Tool cards fly in โ€” which file was read, what command ran, done or failed, all visible. The agent asks a question; a card pops up for the answer. Model switching is a thumb-swipe. Finally, phone and computer connect across deep space: Phone in hand. Computer at your command.

Made with video-shotcraft โ€” picked from 152 shot recipe cards: ink crosshair opening, graze-face tour, card dealing, line-carry transition, 3D terminals, overhead file reveal, segmented control, deep-space outro. Real screenshots, fictional demo data, 31 seconds, 8 shots.

What the promo is really about

One sentence: the phone is the best remote for your agent.

Most people use agents by sitting at the computer watching them work. But the whole point of an agent is that it does the work for you โ€” and yet you have to babysit it. That's backwards.

  • On the commute, want to dispatch a task: phone
  • In bed, want it to start running: phone
  • Mid-meeting, it needs approval: phone, one tap
  • Away from the desk, want to check progress: phone

Mobile isn't a shrunken web page โ€” it's a different paradigm: approvals, questions, and tool cards inline in the message stream, your thumb as the mouse, every step of the agent visible.

Why it's worth a look

  • Zero npm dependencies: one Node process + one HTML file, clone and run
  • Direct 4G/5G: free Tailscale, no public IP
  • Tool cards show paths: which file was read, what changed, the result โ€” tap to expand
  • No deadlocks: the agent asks โ†’ a card pops up โ†’ answer โ†’ it continues
  • MIT open source: ~4000 lines, stars/PRs/issues welcome

Run it in three minutes

Install Tailscale on the phone, open http://<computer IP>:8788/, go.

"Wherever you are, your agent is too." โ€” not a tagline. It's been my real life for two weeks.
