What is knowledge-interaction-surfaces-web-client?

A codebase guide for the browser-based React interface, including sessions, tasks, live updates, navigation, previews, and a web terminal.

Use it for chat input, session switching, SSE reconnects, sidebars, kanban boards, file and diff previews, browser panels, and terminal views.

It helps developers change the web client while keeping browser state, reconnecting event streams, multi-project navigation, and task views aligned.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00164	$0.02619
Opus 5	$0.00082	$0.01309
Sonnet 5	$0.00033	$0.00524
Haiku 4.5	$0.00016	$0.00262

Security

Grade A, and why

knowledge-interaction-surfaces-web-client scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Module Structure

Web Client 将 HTTP 快照、单 Session SSE 与全局任务 SSE 折叠为浏览器状态，并以复合 SessionRef 驱动聊天、看板、Sidebar、预览和终端；它不直接执行 Agent。

Directory Layout

packages/cli/web/src/App.tsx — URL/本地状态恢复、全局订阅和主视图选择
packages/cli/web/src/services/ — HTTP、Session SSE、全局 SSE 与 Browser API 客户端
packages/cli/web/src/store/session/ — Session、消息、流式事件、任务与 UI slices
packages/cli/web/src/components/chat/ — 对话时间线、输入、交互、Goal、Team 与状态
packages/cli/web/src/components/layout/ — Sidebar、导航、响应式壳层与资源入口
packages/cli/web/src/components/tasks/ and packages/cli/web/src/components/kanban/ — 任务创建、切换与多项目看板
packages/cli/web/src/components/preview/ — diff、文件、日志和 Browser 预览
packages/cli/web/src/components/terminal/ — WebSocket PTY 面板
packages/cli/web/src/lib/ — 草稿、Session 导航、身份、附件和快捷键辅助

Key Entry Points

App in packages/cli/web/src/App.tsx — 解析导航意图并选择临时任务、聊天或看板
sessionService.openEventSubscription() in packages/cli/web/src/services/sessionService.ts — 单 Session SSE 与 durable cursor
createSessionSlice() in packages/cli/web/src/store/session/slices/sessionSlice.ts — Session 导航、发送、恢复和任务动作
createEventDispatcher() in packages/cli/web/src/store/session/handlers/eventHandlers.ts — SSE 到 Store/Browser 活动的分发
Layout in packages/cli/web/src/components/layout/Layout.tsx — Sidebar、工作区、预览与终端组合
ChatInput in packages/cli/web/src/components/chat/ChatInput.tsx — Session 级输入、草稿和能力选择

Gotchas

Web 中 Session 身份必须始终是 {sessionId, projectPath}；历史上只比 session ID 会让跨项目同名 Session 的消息、错误、预览和任务状态串线 (packages/cli/web/src/store/session/sessionIdentity.ts, git:d20b6ed5)
selectSession() 必须先打开并缓冲新 SSE，再并行拉取消息/Goal/Session/Team 快照，最后原子提交身份并回放缓冲事件；先替换 Store 再订阅会产生 snapshot/live 空窗 (packages/cli/web/src/store/session/slices/sessionSlice.ts, git:121ea8fc)
新订阅准备失败时旧订阅必须继续存活；replaceEventSubscription() 只能在新连接 ready 后关闭旧连接 (packages/cli/web/src/store/session/slices/streamingSlice.ts, git:b3ffab60)
ChatView 不应在 React effect cleanup 中取消 Store 拥有的 SSE；StrictMode 会重放 effect，组件级 cleanup 曾导致激活后连接被意外关闭 (packages/cli/web/src/components/chat/ChatView.tsx, git:01505f04)
活动 run 的 SSE 不在线时 Composer 必须禁用 steering；HTTP 仍可接收请求不代表客户端能安全观察确认、终态或 follow-up (packages/cli/web/src/components/chat/ChatView.tsx)
所有终态事件和 tool.start 前必须排空 80ms delta 缓冲；否则 prose/reasoning 可能在工具卡或完成状态之后写入 (packages/cli/web/src/store/session/handlers/eventHandlers.ts, packages/cli/web/src/store/session/handlers/streamingBuffer.ts)
session.completed、session.error、idle status 与 abort 会触发权威消息重同步；只依赖 live delta 无法覆盖断线期间的 committed 结果或恢复生成的消息 (packages/cli/web/src/store/session/handlers/eventHandlers.ts, packages/cli/web/src/store/session/slices/sessionSlice.ts)
显式 URL 中的 Session 是权威意图：目标缺失或不可用时必须停在临时页面并保留导航错误，不能静默打开 localStorage 中另一个 Session (packages/cli/web/src/store/session/sessionNavigation.ts)
Composer 草稿按复合 SessionRef 分区；文本与 output schema 写入 sessionStorage，图片只在内存 Map 保存，浏览器刷新后不会恢复图片附件 (packages/cli/web/src/components/chat/ChatView.tsx, packages/cli/web/src/lib/composerDraft.ts)
发送成功后才清草稿；请求拒绝时 Store 删除 optimistic user message，而 ChatInput 保留输入供重试，不能在点击发送时先清空 (packages/cli/web/src/components/chat/ChatInput.tsx, packages/cli/web/src/store/session/slices/sessionSlice.ts)
模型、reasoning、service tier、verbosity 与 permission mode 在活动 run 中被冻结；Composer 可以显示选择器，但发送 steering 时不会携带这些切换，Server 也会拒绝并发切换 (packages/cli/web/src/components/chat/ChatInput.tsx, packages/cli/web/src/store/session/slices/sessionSlice.ts)
FilePreview 的请求必须同时校验 request generation 和当前 SessionRef；仅比较路径或 URL 会让 A→B→A 的旧响应覆盖新 A 状态 (packages/cli/web/src/components/preview/FilePreview.tsx)
worktree Task 交付后文件树浏览 source project，但 durable diff 仍从 Task Session artifact 读取；discard 后则明确隐藏所有旧消息 diff (packages/cli/web/src/components/preview/FilePreview.tsx)
Browser tab 使用 forceMount 保留 iframe/控制状态；切换到 Files/Logs 时不能卸载 Browser 会话 (packages/cli/web/src/components/preview/FilePreview.tsx)
全屏预览仍保留同一个 Chat Composer 和状态投影，只把工作区内容置于覆盖层后；不要为全屏模式创建第二套 ChatView/Input (packages/cli/web/src/components/layout/Layout.tsx, packages/cli/web/src/components/chat/ChatView.tsx, git:3b786d37)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
