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.\n\n**Why**\n\nThis is groundwork in how streamed text is handled. It may change how text is captured while Claude is replying.\n\n- Flag `tengu_shimmying_sparkle`: Not enough to say (read for one account on one subscription tier against v2.1.323; this account: no value returned, anonymous baseline: no value returned, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Environment Variables\n- Names: `CLAUDE_CODE_PLAIN_DELTA_TAKE_AT_SOURCE`\n- Tier: Use it now\n- Useful: 4\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
