输入框预测 · Composer prediction

中文：根据当前对话和你说话的方式，在输入框上方给出你下一条最可能发的消息，按 Tab 即可采用；同时支持输入时补全草稿、一键润色提示词。

English: Predicts your next message in the DSH composer, based on your conversation and how you talk to it. Press Tab to take it. It also completes a draft as you type and rewrites a prompt for clarity on demand.

功能 · Features

中文	English
自动预测	Predicts the next message after each finished turn
手动预测	Predict on demand from the composer tool row
草稿补全	Completes the second half of a draft as you type
润色提示词	Rewrites the current draft into a clearer instruction

按 Tab 接受建议（填进草稿但不发送），Esc 隐藏，「忽略」按钮则永久丢弃。草稿为空时 ←/→ 在候选之间切换（按住修饰键、或输入法正在组合时不会拦截方向键）。 Tab accepts a suggestion (fills the draft, does not send); Esc hides it; the dismiss button forgets it. With an empty draft, ←/→ cycles between candidates (arrows are left alone while a modifier is held or an IME is composing).

安装 · Install

推荐安装预打包的 v0.1.1，不需要源码构建。在 Harness 中让助手使用 plugin_manager install_bundle 安装这个 URL： Install the prepacked v0.1.1 archive with Harness's plugin_manager install_bundle; no source build is required:

https://github.com/Lphehe/dsh-composer-assist/releases/download/v0.1.1/dsh-composer-assist.tgz

普通 CLI profile 可按下面的示例安装（将 web 换成你的 profile 名；Desktop 请使用插件管理器）： For a regular CLI profile, replace web with your profile name; use Plugin Manager for Desktop:

dsh plugin --profile web add https://github.com/Lphehe/dsh-composer-assist/releases/download/v0.1.1/dsh-composer-assist.tgz

也可克隆仓库，再让 plugin_manager install_bundle 安装克隆目录的绝对路径： Alternatively, clone the repository and install its absolute directory path with plugin_manager install_bundle:

git clone https://github.com/Lphehe/dsh-composer-assist.git

v0.1.1 沿用 0.1 系列输入预测功能，本次更新许可与分发；不包含开发中的 ZCode 动态工作流。 v0.1.1 retains the 0.1-series composer features and updates licensing/distribution; it does not include the in-development ZCode dynamic workflows.

建议栏上的「置信度」是模型的自评，只显示为高/中/低三档，不是校准过的概率。 The confidence on the bar is the model's own rough self-assessment, shown only as high/medium/low — not a calibrated probability.

设计要点 · Design notes

• 不写会话日志：预测是 ctx.llm.prepareCall() 的辅助调用，不进入对话历史。 Never writes to the session log: prediction is an auxiliary ctx.llm.prepareCall() call.
• 每轮只预测一次：Host 侧监听 agent/turn-stopping 记账；预测自身产生的 turn 事件会被过滤，并按 turn 号去重。 Exactly one prediction per finished turn: the Host records agent/turn-stopping, filters the prediction's own turn events, and deduplicates by turn number.
• 打字不触发：轮询不依赖草稿内容，键击不会重启轮询或消耗 turn。 Typing never triggers it: polling does not depend on draft content, and keystrokes neither restart the poll nor consume a turn.
• 建议跟着会话走：建议与「生成中」状态都按会话保存在模块级存储，切换对话再切回不会丢失。 Suggestions belong to their conversation: both the suggestion and the generating state are kept per session in a module-level store, so switching away and back does not lose them.
• 不抢宿主的命令提示：行内模式会避让宿主的 --dsh-composer-hint。 Does not steal the host's hint: inline mode avoids the host's --dsh-composer-hint.
• 工作区上下文只给名字：工作目录顶层文件名与 git 分支/改动列表会随提示词一起发送，经宿主 fs / subprocess provider 读取。不读文件内容，过滤常见凭据类文件名；目录最多扫描 200 项、发送 8 个文件名和 20 行 git 状态，缺失或超时不阻断预测。 Workspace context is names only: top-level file names plus the git branch and changed-file list ride along with the prompt through the Host fs / subprocess providers. No file contents are read; common credential-shaped names are filtered. Scanning is capped at 200 entries, with 8 names and 20 git status lines sent; missing context or a timeout does not fail the prediction.

上下文与过期保护 · Context and stale-result protection

• 在现有对话历史字符预算内（不含当前草稿及工作区摘要），优先最新用户请求及回答、较早用户约束，再加入最近最多四条工具文本证据（带工具名、错误标记和截断标记）。不复制隐藏推理、图片、附件、工具参数或整个系统提示词；工具证据不作为指令。
• 预测只给有依据的 1～3 条候选，不强求数量、不新增授权或任务；不确定时可以不给建议。空结果不会清除已有有效候选。
• 请求绑定会话、当前消息视图边界和草稿修订。来源变化、乱序结果或期间改稿的请求不能写入候选；接受前再核对来源，草稿变化时接受按钮禁用。润色期间的新输入也不会被旧结果覆盖。
• 已完成候选仍按会话缓存；旧版无来源缓存不会恢复。只读上下文来自 DSH 的 Session.deriveMessages()，不是完整模型请求快照；不创建活跃预测子会话。

Within the existing character budget, recent user requests/answers and older user constraints take priority, followed by up to four bounded textual tool results. Hidden reasoning, attachments, tool arguments, and system prompts are not copied. Predictions offer 1–3 grounded candidates or abstain. Session/source/draft-revision checks reject outdated responses; acceptance rechecks the source and never overwrites an edited draft. Polishing also protects intervening edits. Completed candidates remain session-local; legacy entries without a source are discarded. This uses the read-only message view, not a full model-request snapshot or an active fork.

硬超时与响应速度 · Hard deadlines and latency

• Host 在工作区准备、等待旧调用退出、模型准备和生成期间执行同一硬截止；浏览器对请求、响应体和来源检查另设配置时限 + 1 秒兜底。接受候选的来源检查最多 5 秒。超时结束「生成中」，丢弃迟到结果，保留有效旧候选，不自动重试。
• 对明确支持 low 推理的模型，只为本次预测、补全或润色调用使用低推理档；其他模型保持默认。不更换模型、不改主会话设置，也不缩减现有上下文。输出预算是否是远端硬限制取决于提供方。
• 截止后会请求取消，但不能保证远端立即停止生成或计费；未结束的调用仍被记账，同会话同类新请求等待它退出，避免叠加后台调用。

The Host enforces one deadline across workspace preparation, previous-call draining, model preparation and generation. The browser bounds the request, response body and source validation by the configured timeout plus one second; acceptance checks have a five-second limit. Late results are discarded without clearing valid suggestions or retrying. Auxiliary calls use low reasoning only when the exact model advertises it, without changing the main session or selected model. Cancellation is best-effort upstream: an unfinished call remains owned until it drains, and replacements do not overlap it. Token-budget enforcement depends on the provider.

实现说明 · Implementation notes

display: inline（行内模式）在空草稿上显示一个非编辑预览，与编辑器共享网格区域并隐藏 placeholder；换行会撑开输入区域。草稿补全复用宿主的 --dsh-composer-hint，跟随文字末尾排版。继续编辑使原建议与草稿不匹配时，行内预览隐藏，候选仍保留在建议栏。接受、切换会话或退出行内模式时会清理插件拥有的提示。

Inline mode shows a non-editable preview over an empty editor, shares its grid area, and hides the placeholder; wrapped text expands the input area. Draft continuations use the host's --dsh-composer-hint at the end of the text. Editing a draft hides a mismatched inline preview while keeping the candidate in the suggestion bar. Accepting, switching sessions, or leaving inline mode clears the plugin's own hints.

预览使用清晰的灰色，常显「预览 · 未填入草稿」与键盘提示；只有 Tab 或接受按钮会填入草稿。候选和选中位置按会话保存在标签页会话存储中，切换会话、重载插件或刷新后会恢复；关闭标签页会清空这份缓存。生成中状态保留在当前页面内存中，正常切换会话不会丢失。

Readable gray text and visible preview/keyboard hints distinguish suggestions from the draft; only Tab or the accept button inserts them. Per-session candidates and selection survive session switches, plugin reloads, and page refreshes in tab session storage. Closing the tab clears this cache. In-flight state lives in page memory and survives normal session switches.

行内显示依赖宿主的 [data-composer-card] / [data-composer-input] 标记及原生提示样式；DSH 升级改名后需要适配。Tab 接受也依赖消息输入框标记，以免搜索等其他输入框误接受候选。

Inline rendering relies on the host's composer markers and native hint styles, which may need adapting after a DSH upgrade. Tab acceptance also checks the message-editor marker so other editable fields, such as search, cannot accept a candidate.

成本提醒 · Cost warning

每次预测都是一次真实计费的模型调用。 默认开启自动模式，即每轮回答后一次调用。可在设置中改为「仅手动」或直接关闭。

Every prediction is a real, billed model call. With auto mode on, that is one call after each finished turn. Switch to manual-only, or turn the plugin off, in the settings page.

自检 · Self-check

克隆仓库后运行 node selfcheck.mjs，检查解析、学习统计和上下文失败降级；不调用模型或改写用户设置。 After cloning, run node selfcheck.mjs for parser, learning-counter and context-fallback checks. It does not call a model or change user settings.
