Narration is gated on CLAUDE_CODE_ENABLE_NARRATION and a server-supplied interval that falls back to 0.

What

A new per-session narration facility hooks into each tool round for non-subagent sessions to produce running commentary. It is off unless CLAUDE_CODE_ENABLE_NARRATION is set, and the interval that paces it comes from a server config value that falls back to 0, meaning no narration when neither is provided.

Details
  • The runner tracks its output sink, whether narration was requested, and the last signature it saw; resetting a session aborts the runner and clears the sink.
  • Narration is additionally suppressed in two detected environments when the environment variable is unset.
