[Plugin / 插件] dsh-composer-history — Terminal-style composer input history / 终端风格输入历史

[PerryLink]

中文

大家好，我做了一个 Web 作曲器输入层插件 dsh-composer-history：把终端的输入历史体验搬进 DeepSeek Harness 的 Web 输入框，并加入了跨会话的智能输入能力。

它解决的是 Web 输入框里的几件日常痛点：半输入的草稿被历史覆盖、找不到之前发过的指令、压缩（compaction）后上下文信息消失。这些都由浏览器本地接管——纯 UI 行为，不产生会话事件、不改 agent-loop、不发模型请求，召回的文字只有在你按 Enter 后才会进入对话。

功能：

• 边缘优先方向键召回：裸 ↑/↓ 先移动光标，仅当光标位于首/末行时才触发历史召回；首次召回暂存 {draft, caret}，回到最新一条（或按 Esc）时精确还原，半截草稿永不丢失；
• 本地持久化历史：每条已发送指令追加到有界的浏览器本地存储，刷新页面、跨会话都还在；
• Ctrl+R 反向搜索：在合并的历史、片段与模板上打开查询浮层；
• 智能输入层：/save//load 跨会话片段、带 {{workspace}}/{{session}}/{{draft}} 变量的提示模板、浏览器本地复用洞察；
• 滑动上下文感知：压缩摘要以 [compacted] … 条目加入召回与搜索，压缩发生时弹一次性提示并可一键 /compact 填充。

安装：

Hi! dsh-composer-history brings terminal-style input history into the DeepSeek Harness Web composer, plus a smart cross-session input layer.

• Edge-first arrow recall — bare ↑/↓ move the caret first; recall triggers only at the first/last line. The first recall stashes {draft, caret} and reaching the newest entry (or Esc) restores both exactly.
• Persisted history — every sent message lands in a bounded browser-local store that survives reloads and reaches across sessions.
• Reverse search — Ctrl+R opens a query overlay over merged history, snippets, and templates.
• Smart input layer — /save//load snippets, prompt templates with {{workspace}}/{{session}}/{{draft}} variables, and browser-local reuse insights.
• Sliding-context aware — compaction summaries join recall/search as [compacted] … entries, and a transient notice announces each compaction with a one-click /compact fill.

Pure UI behavior: no session events, no agent-loop changes, no model requests — recalled text only enters the composer draft.
