Composer Stretch

Auto-expand composer for DeepSeek Harness: a ⤢ button appears at the top-right of the composer card when the text wraps to 3+ visual lines, stretching the input to near-fullscreen height on click.

The plugin will be installed here. Keep web if you are unsure.

dsh-composer-stretch

中文 | English

为 DeepSeek Harness 打造的输入框扩展插件。当输入框内容行数 ≥ 3 行时，输入框右上角出现扩展按钮；点击后输入框高度扩展到全屏，再点击恢复默认高度。

整体交互体验与 Gemini 相似，针对 DSH 再做了些高度适配、修复滚动穿透背景等问题。

安装

# Web profile
dsh plugin --profile web add dsh-composer-stretch

# Desktop 应用：先完全退出 App
dsh plugin --profile desktop add dsh-composer-stretch

触发方式

  • 条件显示 — 输入框行数 ≥ 3 行时，右上角出现扩展按钮，点击可扩展输入框高度
  • 三连换行自动扩展 — 连续按 3 次 Shift+Enter 自动进入扩展模式

扩展后效果

  • 全屏输入 — 扩展后，输入框达到接近全屏高度（已做适配，不会被会话标题、输入框图片等组件遮挡）。
  • 附件让位 — 展开时粘贴图片或文件，输入区自动让出附件轨道的高度（卡片总高度不变），不会被顶出会话可视区
  • 发送后自动折叠 — 发送消息后自动恢复默认高度，无需手动关闭
  • 扩展后 Enter 换行 — 展开模式下 Enter 与 Shift+Enter 换行，Cmd/Ctrl+Enter 发送；收起时 Enter 仍是发送
  • 滚动不穿透 — 扩展后修复 DSH 输入框内滚动到边缘时会滚动背景对话区的问题

其他说明

  • 已适配至 DSH v0.2.0-rc.2
  • 稳定 UI - 依赖高稳定性的 data-slot 标识 + DSH 官方设计令牌，兼容性好，与原生系统适配度极高
  • 不持久化 — 刷新页面恢复默认状态，无 localStorage 残留
  • 纯前端 — 无自定义协议、无 host 命令、无 LLM 调用、不进会话日志
