Measured

2026-08-20 (Claude Code 2.1.238), 2026-09-01 (2.1.251), 2026-09-30 (2.1.284).

What was measured

claude --remote-control gives a session a second control channel. It answers to the Claude account of the session user, from claude.ai/code and the Claude mobile app, and it acts on the same pane.

1. 2.1.238: a pane with the flag drew a /rc marker at the end of the footer. A plain pane drew none.
2. 2.1.251: a plain pane also drew the marker, and Remote Control was on by default. This measurement is superseded.
3. 2.1.284: a plain pane drew no marker, not the word remote, and no session address. A pane with the flag drew all three. The marker moved to the header line at the top of the pane, beside the working directory.

On 2.1.251 the /remote-control command opened a modal with "Disconnect this session", "Show QR code" and "Continue". The mark started on "Continue". The modal draws the input mark with no frame. Escape closed it.

Mechanism

A tool that reads or drives a pane is not the only actor on it. The screen can change between two reads for a reason that the tool did not cause. A reader must give UNKNOWN for the Remote Control modal, and a tool must send no key to it.

Incident

None recorded.

Screens

None. The corpus holds no capture of the modal yet.

Not measured

A plain session on 2.1.284 that carries no channel is an inference from the absence of its address. Nobody opened claude.ai/code for a plain session.
