Claude adds persistent phone control for desktop sessions

Hot take: this is the kind of feature that makes Claude feel less like a chat app and more like an operator surface for long-running work.

• –The persistent thread is the real product value here; it reduces context churn and makes handoff between desktop and phone feel continuous.
• –Permissioned access to local files and browser actions is what makes the workflow useful, not just flashy.
• –The same power creates the biggest risk surface: prompt injection, session hijacking, and sloppy permission grants.
• –If Anthropic nails trust controls and recovery flows, this becomes a compelling remote-agent pattern; if not, it becomes a security footgun.
