Unclear It is not stated what the mode changes for someone who turns it on.
Claude Code has a new mode for how it captures text as it streams in from the model. You can turn it on by setting the environment variable CLAUDE_CODE_PLAIN_DELTA_TAKE_AT_SOURCE to true. An environment variable is a value you set in your shell before starting Claude Code. The mode can also be turned on by a remote switch, which is off unless it is switched on remotely.
This is groundwork in how streamed text is handled. It may change how text is captured while Claude is replying.
