CLAUDE_CODE_REMOTE

env in the build JSON

A Claude Code environment variable, read out of the shipped bundle. It has been in the build since v2.1.138, including the newest one read.

Remote sessions started from review can skip writing some state to disk.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.221.

The earliest release whose published evidence quoted CLAUDE_CODE_REMOTE was v2.1.70, 6 Mar 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.
