Anthropic Claude Duet Links Claude Code: Check, Approve, and Steer Local or Cloud Sessions from Phone

Core Background & Industry Pain Points

Long-running local or cloud coding agents stall when approvals need a laptop. On 2026-11-06, Anthropic Claude Duet co-creator and lead David Sutton (@davidsuttonca) posted that Duet now connects to Claude Code so you can check progress, approve changes, and send updates from a phone—for sessions on your computer or in the cloud. The same day, PM lead Karan Ahuja (@ahuja_karan) confirmed and called it the #1 early-user request. First-hand product-lead update, not an @AnthropicAI blog; Snape Report and daily.dev followed.

Architecture Highlights & Internals

Per Sutton: from the phone, check what is running, approve changes, and send follow-ups; both local and cloud sessions work. Ahuja adds Projects plus continuing Claude chats and memory. Duet remains a standalone proactive-agent app (US Pro/Max/Ultra research-preview waitlist), separate from the main Claude app; code still runs in the original Claude Code environment while Duet is the mobile steer/approve surface.

Authoritative Benchmarks & Measured Scores

No third-party benchmark was published with the posts. Point-in-time X engagement: Sutton demo ~130k impressions and 800+ likes. Availability: Duet research preview still US subscription waitlist. Permission prompts and network/key scope inside Duet were not spelled out—cite as product-lead wording.

Developer Hands-on Guide

If already on the Duet preview: open Duet, connect a Claude Code session, and try check → approve → follow-up. If not, Claude app Code tab / Remote Control docs remain the adjacent path for remote-controlling a local session—related, not the same claim. Attribute to Sutton / Ahuja first-hand posts and link the Claude Duet intro.
