+English | [中文](README.zh.md)

 Plan-mode composer control, a pure browser surface plugin. The browser half occupies the conversation-declared `conversation.input.plan` single seat with a pending-aware mode selector; the node half is an empty apply (the roster row). Plan behavior itself — the `/plan` command, the boundary-committed `plan/mode` state, the `plan` projection unit, and the policy section — is owned by [`@deepseek-ai/dsh-plan-mode`](../../plan/plan-mode/README.md), composed independently on the host roster.
 
 Reads ride the generic projection pair: the control renders the host-computed `plan` projection (`{ active, pending }`) through the standard-kit `useProjection`; an absent key is capability absence and hides the control, so a host without plan-mode (or a Draft with no session) shows no seat content. Writes ride the standard command channel: selecting a mode executes `/plan` or `/plan off` through `command.execute`, whose logged `command/run` immediately folds into a pending projection frame and whose request-boundary `plan/mode` commit resolves it — the control never holds client-side plan state, displays only host-confirmed values, and stays available while generation runs (switching never cancels a turn; the pending target applies at the next model-request boundary).

 ## Model Experience
 
-None directly. Model-visible plan behavior (policy activation, the exit-tool schema, logged state) is owned by `@deepseek-ai/dsh-plan-mode`; this package only renders the projection and dispatches `/plan` lines a user could equally type.
+Indirectly, through the `/plan` command lines the control dispatches: `@deepseek-ai/dsh-plan-mode` owns the model-visible policy section, the exit-tool schema, and the logged state those lines drive, while this package only renders the projection and sends what a user could equally type.
+
+#### KV Cache effect
+
+Entering or leaving plan mode changes the active `plan:policy` system-prompt section and therefore the request prefix; the control itself adds no prompt content.

+# @deepseek-ai/dsh-client-ui-plan
+
+[English](README.md) | 中文
+
+Plan mode 编辑器控件，纯浏览器 surface 插件。浏览器侧以一个感知待生效态的模式选择器占据会话声明的 `conversation.input.plan` 单座；node 侧是空 apply（roster 行）。plan 行为本身——`/plan` 命令、边界提交的 `plan/mode` 状态、`plan` 投影单元与 policy 段——归 [`@deepseek-ai/dsh-plan-mode`](../../plan/plan-mode/README.md) 所有，由 host roster 独立组合。
+
+读取走通用投影对：控件经标准套件的 `useProjection` 渲染 host 计算的 `plan` 投影（`{ active, pending }`）；key 缺席即能力缺席并隐藏控件，因此未组合 plan-mode 的 host（或尚无会话的 Draft）不展示座位内容。写入走标准命令通道：选择模式即经 `command.execute` 执行 `/plan` 或 `/plan off`，其入日志的 `command/run` 立即折叠为 pending 投影帧，请求边界的 `plan/mode` 提交将其兑现——控件不持有任何客户端侧 plan 状态，只显示 host 确认的值，且在生成期间保持可用（切换绝不取消轮次；待生效目标在下一次模型请求边界生效）。
+
+透明的原生 select 把键盘焦点镜像到可见 chip 上，并携带区分已提交与待生效模式的动态无障碍描述。准入失败（`matched: false`、业务错误、传输故障）以内联错误呈现，不改变显示的模式。
+
+模型通过稳定的 `exit_plan_mode` 工具退出 plan mode；其 plan 评审走已组合的 Web question 通道。
+
+## 模型体验
+
+间接地，通过控件派发的 `/plan` 命令行：`@deepseek-ai/dsh-plan-mode` 拥有这些命令行驱动的模型可见 policy 段、退出工具 schema 与已记录状态，本包只渲染投影并发送用户同样可以手敲的内容。
+
+#### KV 缓存效应
+
+进入或离开 plan mode 会改变活跃的 `plan:policy` 系统提示词段，因此改变请求前缀；控件本身不添加任何提示词内容。
+
+## 已知局限与延后工作
+
+- **Plan mode 是引导而非执行沙箱**——需要强制只读规划的部署必须组合独立的沙箱与审批策略。
+- **控件属于默认编辑器**——待处理的整编辑器交互（如 plan 评审）会临时取代 InputBar 及其模式控件。
+- **无 Draft 期选择**——会话存在之前没有投影，座位保持为空；plan mode 在首个 prompt 创建会话后选择。
