# RFC: Dedicated full-screen TUI front door
Status: implemented
English | [中文](2026-07-17-dedicated-full-screen-tui-front-door.zh.md)
## Problem
The line-oriented `@deepseek-ai/dsh-stdio` front door works in pipes and ordinary terminals, but a full-screen coding interface must own raw input, differential screen drawing, cursor state, overlays, and terminal restoration. Combining those contracts in one UI plugin couples the pipe-safe path to a TTY-only lifecycle and makes it unclear which terminal behavior a composition selects.
The interactive channel must remain a Cordis plugin over the same agent, session, tool, and user-interaction services as every other front door. It needs to resume durable history, follow compaction replacements, display tool-owned presentation, and restore the terminal on startup failure and disposal. A standalone chat application or a second agent composition would duplicate behavior outside the plugin graph.
## Decision
DeepSeek Harness ships [`@deepseek-ai/dsh-tui`](../../../../packages/ui/tui/README.md) as a dedicated Cordis plugin. It owns terminal input and presentation only; agent lifecycle, session persistence, tool execution, and the model-facing question tool remain separate composition entries. The plugin requires both stdin and stdout to be TTYs and fails instead of silently changing to line-oriented behavior.
The app layer selects a concrete terminal front door before mounting it. `@deepseek-ai/dsh-stdio-demo` can resolve `auto` from the two process streams, while the `coding-agent` and `tui-agent` leaves explicitly select readline and TUI respectively. The TUI leaf reuses the coding agent's backend and tool composition through an asserted include patch, so the three runnable agent leaves remain symmetric without duplicating deployment choices.
The selected front door receives the exact generated or resumed `SessionId` used by the pre-created agent. It mounts before the agent composition, waits for the matching root agent, and enters full-screen mode only after that agent exists. A matching `agent-loop/config-start-failed` event is therefore reported before screen takeover and exits with status 1.
### Session projection and interaction
The TUI rebuilds the transcript from the active `session.surface` and reprojects it whenever an event carries a `surfaceOp`, so resumed and compacted history matches the model-visible conversation. It renders Markdown text and reasoning, token totals, the latest `todo/write` plan, and tool cards produced through each tool definition's `presentCall` and `presentResult` methods. Pending chunks and tool calls update the same components that completed events settle.
Editor input calls `agent.send()` while idle and `agent.steer()` while a turn is running. Cancellation, reasoning visibility, tool-card expansion, redraw, transcript clearing, and exit are terminal-only controls. The plugin registers the shared `userInteraction` provider and presents questions as queued keyboard overlays; agent behavior and answer logging remain owned by their existing services.
### Terminal ownership
Before model output, session data, tool presentation, questions, configuration, or diagnostics reach pi-tui or the terminal title, `displayText()` renders C0 and C1 controls other than line feeds as visible hexadecimal escapes. Only the TUI and pi-tui create ANSI control sequences.
The built-in palette uses standard 16-color ANSI foregrounds and SGR attributes, keeps body text and backgrounds at terminal defaults, and uses reverse video for selection. Host terminals therefore remap the interface for light and dark themes without a TUI-specific theme setting; `color: false` removes styling.
## Verification
The implemented [TUI terminal-state snapshot RFC](../testing/2026-07-18-tui-terminal-state-snapshots.md) owns the four-layer verification contract: direct behavior tests, transient semantic terminal snapshots, recorded JSONL journeys through production tools, and Loader/PTY smoke tests. The package README owns configuration, commands, model-visible effects, and current limitations.
## Alternatives considered
- **Keep readline and full-screen modes inside `@deepseek-ai/dsh-stdio`** — rejected because line-oriented output and differential TTY rendering have different dependencies, input rules, logging ownership, and teardown obligations. Separate packages keep the pipe-safe contract small and explicit.
- **Let the TUI plugin silently downgrade when either stream is not a TTY** — rejected because a fallback hides deployment mistakes and changes interaction semantics. The app bundle may select a front door with `auto`; an explicitly mounted TUI fails loud.
- **Keep TUI wiring and tests under the readline `coding-agent` leaf** — rejected because one leaf would represent two distinct front doors and break symmetry with `acp-agent`. A dedicated `tui-agent` leaf owns TUI overlays and tests while reusing the coding agent's backend composition.
## Consequences
- Interactive terminal work gains a stateful Markdown, card, plan, and question interface without changing the line-oriented protocol used by pipes and automation.
- The TUI carries a pi-tui dependency and a strict TTY requirement; non-TTY deployments select `@deepseek-ai/dsh-stdio` at composition time.
- Session projection makes resume and compaction consistent with the durable conversation, but one configured session owns the transcript and editor.
- Tool packages extend terminal cards through their existing presentation methods without adding tool-specific branches to the TUI.

# RFC: 独立的全屏 TUI 入口
Status: implemented
[English](2026-07-17-dedicated-full-screen-tui-front-door.md) | 中文
## 问题
逐行输出的 `@deepseek-ai/dsh-stdio` 入口适用于管道和普通终端，但全屏编码界面必须负责原始输入、差分绘制、光标状态、浮层和终端恢复。把这两类契约合并到一个 UI 插件中，会迫使管道安全路径依赖仅适用于 TTY 的生命周期，也使组合无法明确表达所选终端行为。
交互通道必须继续作为 Cordis 插件，使用与其他入口相同的 agent（智能体）、会话、工具和用户交互服务。它需要恢复持久历史、跟随压缩替换、显示工具自有的呈现内容，并在启动失败和资源释放时恢复终端。独立聊天应用或第二套 agent 组合会在插件图之外重复实现这些行为。
## 决策
DeepSeek Harness 将 [`@deepseek-ai/dsh-tui`](../../../../packages/ui/tui/README.md) 作为独立的 Cordis 插件交付。该插件只负责终端输入与呈现；agent 生命周期、会话持久化、工具执行以及模型可见的提问工具仍由不同组合项负责。插件要求 stdin 和 stdout 均为 TTY；条件不满足时会失败，不会静默切换为逐行输出。
应用组合层在挂载前选择具体的终端入口。`@deepseek-ai/dsh-stdio-demo` 可以根据两个进程流通过 `auto` 作出选择，`coding-agent` 和 `tui-agent` 叶节点则分别明确选择 readline 与 TUI。TUI 叶节点通过带断言的 include patch 复用 coding agent 的后端和工具组合，使三个可运行的 agent 叶节点保持对称，同时避免重复部署选项。
所选入口接收预创建 agent 使用的同一个新建或恢复 `SessionId`。入口先于 agent 组合挂载，等待相符的根 agent 出现，然后才进入全屏模式。因此，相符的 `agent-loop/config-start-failed` 事件会在接管屏幕前报告，并以状态码 1 退出。
### 会话投影与交互
TUI 从活跃的 `session.surface` 重建 transcript（文本记录），并在事件携带 `surfaceOp` 时重新投影，因此恢复或压缩后的历史与模型可见会话保持一致。TUI 渲染 Markdown 文本与推理、token 用量、最新 `todo/write` 计划，以及各工具定义通过 `presentCall` 和 `presentResult` 方法生成的工具卡片。进行中的分片与工具调用会更新同一组组件，随后由完成事件收束状态。
agent 空闲时，编辑器输入调用 `agent.send()`；轮次运行中则调用 `agent.steer()`。取消、推理显隐、工具卡片展开、重绘、清空 transcript 和退出都只是终端控制。插件注册共享的 `userInteraction` 提供方，以排队的键盘浮层呈现问题；agent 行为和答案日志仍由既有服务负责。
### 终端所有权
在模型输出、会话数据、工具呈现、问题、配置或诊断信息进入 pi-tui 或终端标题前，`displayText()` 会把换行之外的 C0 和 C1 控制字符显示为十六进制转义文本。只有 TUI 和 pi-tui 可以生成 ANSI 控制序列。
内置配色仅使用标准 16 色 ANSI 前景色和 SGR 属性，正文文字和背景沿用终端默认值，选中项使用反显。因此，宿主终端可以直接按浅色或深色主题重映射界面，无需 TUI 专用主题设置；`color: false` 会移除样式。
## 验证
已实现的 [TUI 终端状态快照 RFC](../testing/2026-07-18-tui-terminal-state-snapshots.md) 规定四层验证契约：直接行为测试、瞬态语义终端快照、通过生产工具执行的已录制 JSONL 流程，以及 Loader/PTY 冒烟测试。包（package）README 负责记录配置、命令、模型可见效果和当前限制。
## 曾考虑的替代方案
- **把 readline 与全屏模式都保留在 `@deepseek-ai/dsh-stdio` 中**：不予采纳，因为逐行输出和差分 TTY 渲染具有不同的依赖、输入规则、日志所有权和资源清理义务。拆分为独立包可以让管道安全契约保持精简、明确。
- **当任一进程流不是 TTY 时，让 TUI 插件静默降级**：不予采纳，因为回退会掩盖部署错误并改变交互语义。应用包可以通过 `auto` 选择入口；明确挂载的 TUI 会快速失败。
- **把 TUI 接线与测试保留在 readline `coding-agent` 叶节点下**：不予采纳，因为一个叶节点会代表两个不同入口，也会破坏它与 `acp-agent` 的对称性。独立的 `tui-agent` 叶节点负责 TUI 浮层和测试，同时复用 coding agent 的后端组合。
## 后果
- 交互式终端获得带状态的 Markdown、卡片、计划和提问界面，同时不会改变管道与自动化使用的逐行协议。
- TUI 会引入 pi-tui 依赖并严格要求 TTY；非 TTY 部署在组合时选择 `@deepseek-ai/dsh-stdio`。
- 会话投影使恢复和压缩与持久会话保持一致，但只有一个已配置会话拥有 transcript 和编辑器。
- 工具包通过既有呈现方法扩展终端卡片，无需在 TUI 中增加工具专用分支。

# RFC: Snapshot semantic terminal state for the TUI
Status: implemented
English | [中文](2026-07-18-tui-terminal-state-snapshots.zh.md)
## Problem
The TUI is a stateful renderer. Its user-visible result depends on ANSI parsing, differential frames, wrapping, scrollback, viewport position, terminal width, focus, cursor state, and each tool's presentation intent. Unit tests that collect `Terminal.write()` fragments can prove event handling, but they cannot prove the final screen a terminal displays. The same screen may also be emitted through different write fragments, so pinning those fragments creates false regressions.
Component-line snapshots stop before ANSI reaches a terminal and miss cursor movement, clearing, styling, overlay composition, and reflow. Raster screenshots include font and platform rendering noise that is unrelated to the TUI contract. A completed flow built by directly appending plausible session events has another blind spot: it proves the renderer accepts those shapes, not that the production agent loop and tool implementations produce them.
The TUI therefore needs a deterministic, reviewable representation of terminal state, recorded model journeys that execute the real downstream stack, and a smaller test at the real process and PTY boundary.
## Decision
TUI coverage has four complementary layers:
1. `packages/ui/tui/tests/tui.spec.ts` tests event mapping, input routing, disposal, and error behavior directly.
2. `packages/ui/tui/tests/tui.snapshot.ts` mounts the production TUI against a headless terminal emulator for transient states that a completed session log cannot retain: in-flight streaming, pending tool calls, overlays, expansion, compaction reflow, errors, and shutdown.
3. `examples/tui-agent/tests/tui.snapshot.ts` replays committed JSONL session logs through the production agent loop and real tools, then compares the resulting semantic terminal state.
4. `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` boots the real Loader composition in a PTY, drives a scripted conversation through streaming and `ask_user_question`, and verifies startup, input, exit, failure reporting, and terminal restoration.
The runnable TUI has its own `examples/tui-agent` leaf beside the readline `coding-agent` and `acp-agent` leaves. It reuses the coding agent's backend and tool composition through an asserted include patch while fixing the shared terminal app to `ui.mode: tui`; TUI snapshots and PTY tests live with that leaf.
### Recorded-session replay
Each example-level scenario directory owns `session.jsonl`, optional child logs `session.<n>.jsonl`, and `terminal.golden.txt`. The primary log supplies user-authored `user/message` prompts and the recorded `assistant/chunk` sequence. `dsh-llm-replay` derives one model-call script per session, binds child logs to fresh child sessions, and is the only mocked boundary. The agent loop, bash and filesystem implementations, Code Mode worker, subagent provider, workflow worker, Cordis tools, presenters, and TUI are production implementations.
The suite rejects a journey when its tool-call sequence differs, an expected event count is missing, a tool result is an error, a turn ends in error, a workflow lifecycle is incomplete, or the live child-session count differs from the fixture set. These assertions prevent an attractive terminal golden from hiding a failed or bypassed production path.
The live-model fixtures use `DSH_SNAPSHOT=record`; record mode rewrites their primary and child JSONL logs and terminal goldens. The deterministic Cordis toolchain keeps an authored complete JSONL script because reliably coercing a live model through five exact tool boundaries and two children is not a stable recording contract. `DSH_SNAPSHOT=refresh` replays every committed script keylessly and rewrites only derived terminal goldens. Plain replay compares without writing, and unknown mode values fail loud.
### Semantic terminal projection
The package-local `HeadlessTerminal` implements the same pi-tui `Terminal` interface as the process terminal and feeds every ANSI write into the pinned `@xterm/headless` parser. Snapshot code waits for synchronized frames to quiesce before reading state, so a checkpoint represents a completed screen rather than a timer-dependent write prefix.
Each golden projects dimensions, active-buffer and viewport coordinates, lifecycle and cursor state, rows, wrap markers, and non-default style ranges into text. Scroll-heavy cards capture the used buffer; overlays capture the visible viewport. Text and style remain separate so a reviewer can distinguish content changes from presentation changes without decoding ANSI bytes.
Every checkpoint enforces theme independence across the complete terminal state: no RGB colors, no palette entries beyond ANSI 0–15, and no explicit background colors. Reverse video remains valid for selection because it uses terminal defaults. Both suites own closed inventories that reject missing scenarios, missing checkpoints, and orphaned golden files.
### Required scenario matrix
| Layer | Scenario | Contract pinned |
|---|---|---|
| Recorded journey | Multi-turn conversation | Recorded reasoning/text chunks, two input turns, retained history, token totals, and idle editor state |
| Recorded journey | Todo plan | Real `todo_write` execution, result card, and persistent plan rendering |
| Recorded journey | Bash terminal card | Real local executor output, description, exit status, and completed terminal card |
| Recorded journey | Parallel filesystem reads | Two calls from one assistant message, real file contents, ordering, and separate completed cards |
| Recorded journey | Code Mode | Real `run_code` worker execution, two `tool/code-dispatch` events, captured program output, and completed card |
| Recorded journey | Dynamic workflow | Real workflow worker, phase lifecycle, replayed child session, structured return value, and completed card |
| Recorded journey | Cordis dynamic toolchain | Real mount, Code Mode inspect, direct subagent, workflow child, unmount, and all production presenters |
| Transient state | Streaming and pending advanced calls | In-flight reasoning/text plus pending Code Mode, workflow, and Cordis cards that disappear from completed logs |
| Transient state | Cards, interaction, layout, failure, and shutdown | Collapsed/expanded card families, question validation, compaction replacement, resize reflow, help/errors, cursor restoration, and terminal stop |
## Alternatives considered
- **Snapshot raw terminal writes** — rejected because differential rendering may change write boundaries without changing the screen, while cursor and clear sequences are unreadable in review.
- **Snapshot component render lines before terminal output** — rejected because it does not test ANSI parsing, cursor movement, overlays, viewport behavior, or independent components in one frame.
- **Build every completed flow by appending session events** — rejected because a hand-authored event sequence can drift from the agent loop, tool execution, child-session binding, or worker behavior while its presentation test stays green. Direct event construction remains limited to transient renderer states.
- **Reuse ACP stdout goldens as the TUI oracle** — rejected because a recorded model journey is transport-neutral but its presentation is not. TUI scenarios own terminal goldens while using the same JSONL replay vocabulary.
- **Commit raster screenshots** — rejected because fonts, glyph metrics, antialiasing, and host terminal themes make them platform-sensitive and make semantic style changes difficult to review.
- **Use only PTY end-to-end tests** — rejected because raw PTY output is a stream of historical drawing operations, not queryable final state. PTY tests retain the real Loader/input/teardown boundary, while the emulator owns broad state coverage.
## Consequences
- Completed advanced snapshots now fail when the real Code Mode, workflow, subagent, filesystem, bash, or Cordis path breaks, rather than accepting a fabricated result event.
- TUI visual regressions produce readable cell-and-style diffs, while JSONL fixtures retain the exact model chunks that made the production path execute.
- The emulator uses xterm's proposed buffer API. An xterm upgrade requires rerunning and reviewing the semantic projection; terminal-specific behavior still needs the PTY smoke.
- Goldens deliberately encode wrapping and viewport behavior at fixed sizes. Intentional layout changes use keyless refresh, while model-journey changes use record mode and review both JSONL and terminal diffs.

# RFC: TUI 语义终端状态快照
Status: implemented
[English](2026-07-18-tui-terminal-state-snapshots.md) | 中文
## 问题
TUI 是有状态的渲染器。用户最终看到的结果取决于 ANSI 解析、差分帧、换行、回滚缓冲、视口位置、终端宽度、焦点、光标状态，以及各工具的呈现意图。收集 `Terminal.write()` 片段的单元测试可以验证事件处理，却无法验证终端最终显示的画面。同一画面也可能由不同的写入片段产生，因此固定这些片段会制造误报。
组件行快照止于 ANSI 进入终端之前，无法覆盖光标移动、清屏、样式、浮层组合和重排。栅格截图会带入与 TUI 契约无关的字体和平台渲染噪声。直接追加看似合理的会话事件来构造完整流程还存在另一处盲区：这种测试只能证明渲染器接受这些数据形态，无法证明生产环境的 agent loop（智能体循环）和工具实现会生成这些事件。
因此，TUI 既需要确定、便于评审的终端状态表示，也需要通过已录制模型流程执行真实下游组件，并保留一项范围更小、覆盖真实进程与 PTY 边界的测试。
## 决策
TUI 覆盖分为四个互补层次：
1. `packages/ui/tui/tests/tui.spec.ts` 直接测试事件映射、输入路由、资源释放和错误行为。
2. `packages/ui/tui/tests/tui.snapshot.ts` 将生产 TUI 挂载到无界面终端模拟器，覆盖完整会话日志无法保留的瞬态：进行中的流式输出、待完成工具调用、浮层、展开状态、压缩重排、错误和关闭过程。
3. `examples/tui-agent/tests/tui.snapshot.ts` 通过生产 agent loop 和真实工具回放已提交的 JSONL 会话日志，再比较生成的语义终端状态。
4. `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` 在 PTY 中启动真实 Loader 组合，驱动一段经过流式输出和 `ask_user_question` 的脚本化会话，并验证启动、输入、退出、失败报告和终端恢复。
可运行 TUI 在 `examples/tui-agent` 中拥有独立叶节点，与 readline `coding-agent` 和 `acp-agent` 叶节点并列。它通过带断言的 include patch 复用 coding agent 的后端与工具组合，只把共享终端应用固定为 `ui.mode: tui`；TUI 快照和 PTY 测试也归属这个叶节点。
### 已录制会话回放
每个示例级场景目录都包含 `session.jsonl`、可选的子会话日志 `session.<n>.jsonl`，以及 `terminal.golden.txt`。主日志提供用户来源的 `user/message` 提示词和已录制的 `assistant/chunk` 序列。`dsh-llm-replay` 为每个会话派生一份模型调用脚本，并将子日志绑定到新建的子会话；这是测试中唯一的 mock 边界。agent loop、bash 与文件系统实现、Code Mode worker、subagent 提供方、工作流 worker、Cordis 工具、呈现器和 TUI 都使用生产实现。
如果工具调用顺序不符、预期事件数量不足、工具结果报错、轮次以错误结束、工作流生命周期不完整，或者实时子会话数量与 fixture（测试前置数据）集合不一致，测试都会失败。即使终端金标表面正确，这些断言也能阻止失败或被绕过的生产路径混入结果。
真实模型 fixture 通过 `DSH_SNAPSHOT=record` 更新；录制模式会重写其主会话与子会话 JSONL 日志以及终端金标。确定性的 Cordis 工具链保留一份人工编写的完整 JSONL 脚本，因为要求真实模型稳定经过五个指定工具边界和两个子会话并不是可靠的录制契约。`DSH_SNAPSHOT=refresh` 会无密钥回放所有已提交脚本，并且只重写派生的终端金标。普通回放只比较而不写入，未知模式值会快速失败。
### 语义终端投影
包内的 `HeadlessTerminal` 实现与进程终端相同的 pi-tui `Terminal` 接口，并把每次 ANSI 写入交给固定版本的 `@xterm/headless` 解析器。读取状态前，快照代码会等待同步帧稳定，因此每个检查点表示已经完成的画面，而不是依赖计时的写入前缀。
每份金标把终端尺寸、活动缓冲区和视口坐标、生命周期与光标状态、各行、换行标记以及非默认样式区间投影为文本。滚动内容较多的卡片捕获已使用缓冲区；浮层捕获可见视口。文本和样式相互分离，评审人无需解码 ANSI 字节即可区分内容变化与呈现变化。
每个检查点还会对完整终端状态强制执行主题无关性：禁止 RGB 颜色、禁止 ANSI 0–15 以外的调色板项，也禁止显式背景色。选择行使用终端默认色进行反显，因此仍然有效。两套测试都拥有封闭清单，会拒绝缺失的场景、缺失的检查点和遗留金标文件。
### 必需场景矩阵
| 层次 | 场景 | 固定的契约 |
|---|---|---|
| 已录制流程 | 多轮会话 | 已录制的推理与文本分片、两轮输入、保留历史、token 总量和空闲编辑器状态 |
| 已录制流程 | Todo 计划 | 真实 `todo_write` 执行、结果卡片和持久计划渲染 |
| 已录制流程 | Bash 终端卡片 | 真实本地执行器输出、说明、退出状态和已完成终端卡片 |
| 已录制流程 | 并行文件读取 | 同一条 assistant 消息中的两次调用、真实文件内容、顺序和两个独立完成卡片 |
| 已录制流程 | Code Mode | 真实 `run_code` worker 执行、两条 `tool/code-dispatch` 事件、捕获的程序输出和已完成卡片 |
| 已录制流程 | 动态工作流 | 真实工作流 worker、阶段生命周期、回放的子会话、结构化返回值和已完成卡片 |
| 已录制流程 | Cordis 动态工具链 | 真实挂载、Code Mode 检查、直接 subagent、工作流子会话、卸载和全部生产呈现器 |
| 瞬态 | 流式输出与待完成高级调用 | 进行中的推理和文本，以及完整日志中不会保留的待完成 Code Mode、工作流和 Cordis 卡片 |
| 瞬态 | 卡片、交互、布局、失败和关闭 | 折叠与展开的卡片族、问题校验、压缩替换、尺寸重排、帮助与错误、光标恢复和终端停止 |
## 曾考虑的替代方案
- **快照原始终端写入**：不予采纳，因为差分渲染可能在画面不变时改变写入边界，而且光标与清屏序列难以评审。
- **快照进入终端输出之前的组件渲染行**：不予采纳，因为它无法测试 ANSI 解析、光标移动、浮层、视口行为，也无法测试独立组件在同一帧中的相互作用。
- **通过追加会话事件构造所有完整流程**：不予采纳，因为人工编写的事件序列可能与 agent loop、工具执行、子会话绑定或 worker 行为发生偏差，但呈现测试仍然保持绿色。直接构造事件只用于渲染器瞬态。
- **复用 ACP stdout 金标作为 TUI 判定依据**：不予采纳，因为已录制模型流程与传输方式无关，其呈现方式却并非如此。TUI 场景使用同一套 JSONL 回放词汇，但拥有独立的终端金标。
- **提交栅格截图**：不予采纳，因为字体、字形度量、抗锯齿和宿主终端主题会使结果依赖平台，也会增加语义样式变更的评审难度。
- **只使用 PTY 端到端测试**：不予采纳，因为原始 PTY 输出是一系列历史绘制操作，而不是可查询的最终状态。PTY 测试保留真实 Loader、输入与清理边界，模拟器负责广泛的状态覆盖。
## 后果
- 当真实 Code Mode、工作流、subagent、文件系统、bash 或 Cordis 路径损坏时，已完成高级快照会失败，不会继续接受伪造的结果事件。
- TUI 视觉回归会产生便于阅读的单元格和样式 diff，而 JSONL fixture 会保留触发生产路径的确切模型分片。
- 模拟器使用 xterm 的拟议缓冲区 API。升级 xterm 时必须重新运行并评审语义投影；终端特有行为仍需由 PTY 冒烟测试覆盖。
- 金标有意固定指定尺寸下的换行与视口行为。预期布局变更使用无密钥刷新；模型流程变更使用录制模式，并同时评审 JSONL 与终端 diff。

- **Unit** (`pnpm run test`): vitest over `packages|examples/*/tests/**/*.spec.ts`, colocated with what they test. Every registry gets an HMR-safety test (dispose the contributing fiber, assert cleanup). Prefer edge cases, error paths, event ordering, concurrency races, and permanent contract regressions (see `packages/core/agent-loop/tests/contract-regressions.spec.ts`).
- **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate is correctly flagging for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped.
- **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e RFC](rfc/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
- **Snapshot** (`pnpm run test:snapshot`): boots the real example subprocess, replays a recorded session keyless, diffs normalized stdout + the re-persisted log against committed goldens ([snapshot RFC](rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md)). Use `pnpm run test:snapshot:record` when the model transcript should change; use `pnpm run test:snapshot:refresh` when the committed transcript is still the right mock LLM input and replay goldens need keyless rewrite. Review the golden diff. System-prompt/tool-schema content is pinned by ONE scenario (`text-turn`) and tokenized in every other fixture, so a prompt or schema edit churns one committed line ([pinned-header RFC](rfc/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).

ACP suites boot the real example subprocess, replay a recorded session, and diff normalized stdout plus the re-persisted log ([ACP snapshot RFC](rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md)). TUI completed journeys replay recorded primary/child JSONL through the real agent loop and tools before projecting ANSI into semantic terminal-state goldens; package-local snapshots retain transient renderer states, and a real PTY conversation covers the process boundary ([TUI snapshot RFC](rfc/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)). Use `pnpm run test:snapshot:record` when a model transcript must change and `pnpm run test:snapshot:refresh` when committed replay input remains correct; review every JSONL and golden diff.

| Entry | Demonstrates |
|---|---|
| `hmr` (`@cordisjs/plugin-hmr`) | the dev/demo edit-reload loop — a **leaf** entry (not baked into the app) because it is Loader-only and needs `node --expose-internals`, which `demo:repl` passes |

| `bash` (`dsh-bash-local`) | the executor implementation — the swappable half of the bash seam. The model-facing `bash` schema (`tool-bash`) and generic `task_*` controls (`tool-tasks`) come from `dsh-agent-spine-demo`, so only the executor is a leaf choice |

| `tool-subagent`, `tool-subagent-fork` | two model-facing `dsh-tool-subagent` loads, each bound to a different provider and exposed under a distinct tool name (`subagent`, `subagent_fork`) |

| `tool-todo` | the model-facing `todo_write` tool; writes the whole task list to the session log and renders as a persistent TUI plan or readline checklist |
| `fs-local`, `fs-policy`, `tool-fs` | the filesystem stack: the local `ctx.fs` provider, the read-before-write/edit policy gate (on the `fs/*` event gate), and the model-facing `read`/`write`/`edit` tools. Relative paths resolve against the session workspace |

# tui-agent
The full-screen terminal counterpart to the [`coding-agent`](../coding-agent/README.md) readline REPL and [`acp-agent`](../acp-agent/README.md) server. It reuses the coding agent's backends and tool composition, then fixes the shared terminal app to the `dsh-tui` front door.
## Run it
```sh
pnpm run demo:tui
```
The command needs `DEEPSEEK_API_KEY` in the environment or the gitignored repository-root `.env`. Set `RESUME_SESSION_ID` to reopen a persisted conversation under `./.sessions`.
The TUI renders Markdown history, reasoning, tool-owned terminal/diff/generic cards, token totals, and the latest todo list. Enter submits or steers while the agent is running; Ctrl+O expands cards, Ctrl+R toggles reasoning, Escape cancels, and `/help` lists commands. `ask_user_question` opens a keyboard-driven overlay.
Run `pnpm run demo:code-mode tui` for the sibling Code Mode overlay.
## Composition
[`cordis.yml`](cordis.yml) includes the readline coding-agent leaf so the LLM, bash, filesystem, compaction, subagent, workflow, todo, timeout, and spill choices have one owner. Its asserted patch replaces only the terminal app config and forces `ui.mode: tui`; [`code-mode.cordis.yml`](code-mode.cordis.yml) applies the same front-door patch to the coding agent's Code Mode overlay.
## Snapshot tests
`tests/snapshots/<scenario>/session.jsonl` supplies recorded user prompts and model chunks; sibling child logs drive subagents and workflows. The keyless suite executes those scripts through the real loop and tool implementations, then compares readable terminal cell/style goldens. Use `pnpm run test:snapshot:refresh` for presentation-only changes and `pnpm run test:snapshot:record` with a DeepSeek key when a recorded model journey changes. The implemented [TUI snapshot RFC](../../docs/rfc/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md) owns the scenario matrix and the split between recorded journeys, transient package snapshots, and PTY coverage.

Fresh stdio sessions use the process launch directory as `session.header.cwd` and mint one combined `main-session-<uuid>` agent/session id, so durable restarts cannot collide. The app passes that exact opaque id to both its config-created agent and UI; an AgentLoop-only reload resumes materialized history under that id, while the UI's `main` text remains only a display label and never selects another registry root by prefix or insertion order. Readline buffers nonblank startup input for that identity until `agent/session-start`, so piped stdin cannot outrun asynchronous exact-id restoration or let EOF discard the queued prompt; `agent-loop/config-start-failed` instead drains and reports buffered input so a missing or corrupt persisted session cannot hang EOF. A resumed run binds both components to the exact `resumeSessionId` and keeps the cwd stored in the persisted session header.

## Known Limitations and Deferred Work
- **One pre-created `main` agent drives the readline UI** — there is no multi-session or concurrent-agent surface in this app; a run is one conversation.
- **One pre-created `main` agent drives the selected terminal UI** — there is no multi-session or concurrent-agent surface in this app; a run is one conversation.
- **The front-door cluster is fixed in code** — the JSONL persistence backend and the ask-user tooling are baked; a different composition is a leaf-level sibling entry or another app package.
- **The question tool is not an approval answerer** — this app mounts `user-interaction` and `ask_user_question`, but not `ctx.approval`; a `tools/pre-execute` `ask` therefore fails closed unless the leaf composes an approval service and terminal answerer.

# @deepseek-ai/dsh-tui
The interactive terminal front door for DeepSeek Harness agents, built on [`@earendil-works/pi-tui`](https://www.npmjs.com/package/@earendil-works/pi-tui). It requires stdin and stdout TTYs; scripts and Loader pipes should compose [`@deepseek-ai/dsh-stdio`](../stdio/README.md) instead.
The implemented [TUI feature RFC](../../../docs/rfc/implemented/feature/2026-07-17-dedicated-full-screen-tui-front-door.md) owns the front-door decision; the [terminal-state snapshot RFC](../../../docs/rfc/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md) owns its verification strategy.
This package owns interactive terminal presentation and input only. It injects `agents`, `tools`, and `userInteraction`, then drives an agent created or resumed by app or developer code. Agent lifecycle, persistence, and the model-facing [`ask_user_question`](../tool-ask-user/README.md) tool remain separate composition entries.
The TUI rebuilds resumed history from the active session surface, renders Markdown responses and reasoning, applies each tool's `presentCall` / `presentResult` intent to terminal, diff, or generic cards, keeps the latest `todo/write` plan above the editor, and presents `ctx.userInteraction` questions as keyboard-driven overlays. Surface replacement events rebuild the transcript so compacted history does not reappear.
Before model output, session events, tool presenters, questions, configuration, or diagnostics reach pi-tui's ANSI-aware renderers or the terminal title, the TUI renders C0 and C1 controls other than line feeds as visible `\xNN` text. Those sources cannot add terminal control sequences; the TUI and pi-tui retain ownership of terminal rendering and styling.
While the agent is running, editor submissions call `agent.steer()`; otherwise they call `agent.send()`. Ctrl+C or Escape cancels a running turn. Ctrl+O expands tool cards, Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle. `/help`, `/clear`, `/cancel`, `/reasoning`, `/tools`, `/redraw`, and `/exit` provide the same actions without key chords.
## Config
| Key | Default | Meaning |
|---|---|---|
| `welcome` | `ready.` | Header subtitle |
| `sessionId` | `main` | Exact shared agent/session identity driven by the terminal |
| `showReasoning` | `true` | Render reasoning blocks |
| `maxToolOutputLines` | `12` | Collapsed tool-card output limit |
| `maxQuestionOptions` | `8` | Visible options in a question overlay |
| `questionDialogWidth` | `72` | Question-overlay width in columns |
| `questionDialogMaxHeight` | `20` | Question-overlay maximum rows |
| `showHardwareCursor` | `false` | Show the hardware cursor at pi-tui's IME marker |

showReasoning: true
maxToolOutputLines: 12
```
Startup fails before mounting when either process stream is not a TTY. The composing app must mount the TUI before its config-created agent so the front door can observe `agent-loop/config-start-failed`; a matching exact-session failure is written before fullscreen mode starts and exits with status 1 instead of leaving a blank terminal. Disposal stops loaders, rejects pending questions, drains terminal input, restores terminal state, unregisters event listeners and the user-interaction provider, and never exits a replacement process during HMR.
## Color
The palette uses the standard 16-color ANSI foregrounds and SGR attributes, which every terminal remaps to its active color scheme, so it stays readable on light and dark backgrounds alike. Body text keeps the terminal's default foreground rather than a fixed shade. Grouped regions (user prompts, tool cards) use a colored left-gutter bar instead of a filled background block, and the question overlay's active row uses reverse video; both are foreground-only, so they never collide with the terminal background. Set `color: false` to strip all styling.
## Model Experience
### Interactive prompt input
**What the model sees**: Each non-empty editor submission becomes one text block, sent with `agent.send()` while the target agent is idle and `agent.steer()` while it is running. Slash commands and keybindings are TUI-only.
**Token effect**: Submitted text is retained under the agent loop's normal session-history and compaction rules. Headers, cards, Markdown rendering, status lines, plans, and help text add no tokens.
### Interactive user-question answers
**What the model sees**: When a consumer calls `ctx.userInteraction.ask()`, this provider presents each question in order and returns selected option labels or `custom` text. Abort, cancellation, or UI disposal becomes `Error: ask_user_question was interrupted before the user answered` through `dsh-tool-ask-user`.
**Token effect**: Waiting and terminal overlays add no tokens; the resolved answer or error is model-visible only through the calling tool or plugin's result.
## Known Limitations and Deferred Work
- **One configured session owns the transcript and editor** — questions from other agents can still use the shared overlay provider, but session rendering and prompt input remain bound to `sessionId`.
- **Tool cards are text terminal presentations** — terminal, diff, and generic cards use tool-owned titles/content, but session content currently has no image block for inline image rendering.
- **Non-TTY operation is intentionally unsupported** — app bundles that need automation must select `dsh-stdio` before mounting this plugin rather than expecting an internal fallback.
