In recent versions of Claude Code, assistant responses render token-by-token (letter-by-letter) in the interactive terminal UI. In earlier versions, responses appeared to display as complete messages (or complete paragraphs) at once.

Request: Add a settings.json option (e.g. "streamOutput": false or "bufferResponses": true) to restore the old behavior — buffer the full response and display it at once, or at least per-paragraph.

Why: The continuous letter-by-letter motion is visually taxing / causes eye strain for some users over long sessions. prefersReducedMotion: true appears to only affect spinners, not the response text streaming.

Platform: Windows 11, Claude Code CLI (interactive mode).

extent analysis

TL;DR

Adding a settings.json option to buffer responses and display them at once may help mitigate the visually taxing effect of token-by-token rendering.

Guidance

  • Investigate the feasibility of introducing a "streamOutput": false or "bufferResponses": true option in the settings.json file to control response rendering behavior.
  • Consider the potential impact of this change on other features, such as spinners, which are currently affected by the prefersReducedMotion setting.
  • Review the existing rendering logic to determine the best approach for buffering responses, whether per-message or per-paragraph.
  • Evaluate the potential for user configuration and customization of response rendering behavior.

Example

No code snippet is provided due to the lack of specific implementation details in the issue.

Notes

The solution may require modifications to the Claude Code CLI's rendering engine and user settings handling. The prefersReducedMotion setting's current behavior should be taken into account to avoid unintended consequences.

Recommendation

Apply a workaround by introducing a buffering option, as it directly addresses the user's concern about visually taxing response rendering. This approach allows for a targeted solution without affecting other features.
