+# Agent Note: Remove the separate CLI demo
+
+Status: implemented

+
+## Problem
+
+After [`dsh run`](../feature/2026-08-08-dsh-run-headless-command.md) became the product one-shot command, `@deepseek-ai/dsh-cli-demo` remained a second application package for the same job. It carried another executable, argument grammar, app composition, cancellation lifecycle, text/JSON/stream-JSON output contract, built artifact, documentation surface, and test suite. The two front doors also assembled different trees, so a successful demo did not prove the shipped `headless` profile and users had to choose between overlapping commands.
+
+The replay suites still need canonical session events to pin assembled backend behavior. That testing need does not require a published command or compatibility contract.
+
+## Decision
+
+Delete `@deepseek-ai/dsh-cli-demo` completely: its package, bin, parser, app plugin, output formats, tests, workspace references, generated-catalog entries, and active documentation. No alias or compatibility package remains. The root `demo:headless` script is retained only as a direct alias of `dsh run`; the product command owns final-text stdout, the observation URL on stderr, persistence, exit status, and shutdown.
+
+`examples/headless-agent` becomes an explicit test composition. Its Loader configs mount `@deepseek-ai/dsh-agent-spine-demo`, one root agent, JSONL persistence, and checkpoint policy as separate rows instead of hiding them behind an app bundle. An unexported example-owned TypeScript fixture drives a task and emits canonical events as JSONL for replay snapshots. It is launched only by tests, has no package export or bin, and is not a supported product output format.
+
+## Alternatives considered
+
+- **Keep `dsh-cli-demo` as an alias or wrapper around `dsh run`.** Rejected because a second bin and package would preserve two discoverable owners without adding capability.
+- **Move JSON and stream-JSON flags onto `dsh run`.** Rejected because no current product consumer requires them; adopting the old demo protocol would enlarge the canonical CLI contract solely to save test machinery.
+- **Delete the canonical-event snapshots with the package.** Rejected because they pin model-visible assembled behavior that final-text product acceptance cannot observe.
+- **Keep the app plugin but delete only its bin.** Rejected because the hidden composition would still duplicate the explicit headless profile and conceal which services the test leaf mounts.
+
+## Consequences
+
+This is intentionally breaking. `dsh-cli-demo`, its `--output-format` choices, and imports from `@deepseek-ai/dsh-cli-demo/src/cli.ts` no longer resolve. There is no public event-stream replacement in this change; callers use `dsh run` for one-shot execution and must choose an existing protocol surface when they need structured automation.
+
+The repository retains backend replay coverage through test-only infrastructure, while product smoke and built-bin acceptance exercise `dsh run`. A separate one-shot package may return only if it owns a genuinely independent, versioned protocol that cannot belong to the product launcher; a second spelling or output shim is not enough.
+
+## Verification
+
+Focused Loader smokes cover the explicit composition in source and plain-Node built modes, snapshot tests diff its canonical JSONL and persisted logs, product acceptance covers `dsh run`, and documentation plus generated graph/catalog gates reject live references to the removed package. The frozen Agent Note archive remains historical evidence and is not rewritten.

+## 决策
+
+彻底删除 `@deepseek-ai/dsh-cli-demo`：包括它的包、bin、解析器、应用插件、输出格式、测试、workspace 引用、生成目录条目和现行文档。不保留别名或兼容包。根目录的 `demo:headless` 脚本仅作为 `dsh run` 的直接别名保留；stdout 上的最终文本、stderr 上的观察 URL、持久化、退出状态和关闭行为均由产品命令负责。
+
+`examples/headless-agent` 成为显式测试组装。其 Loader 配置把 `@deepseek-ai/dsh-agent-spine-demo`、一个根 agent（智能体）、JSONL 持久化和检查点策略挂载为独立配置行，不再将其隐藏在应用组合包之后。一个由示例自有且未导出的 TypeScript fixture（测试前置数据）会驱动任务，并以 JSONL 发出供回放快照使用的规范事件。该 fixture 只由测试启动，没有包导出或 bin，也不是受支持的产品输出格式。
+
+## 考虑过的替代方案
+
+- **保留 `dsh-cli-demo` 作为 `dsh run` 的别名或包装层。** 不予采纳：第二个 bin 和包会让同一功能继续存在两个可发现的归属方，却没有增加任何能力。
+- **把 JSON 和 stream-JSON 标志移到 `dsh run`。** 不予采纳：当前没有产品消费方需要这些标志；沿用旧 demo 协议，只会为了保留测试机制而扩大规范 CLI（命令行界面）契约。
+- **随包一并删除规范事件快照。** 不予采纳：这些快照固定了模型可见的组装行为，而只检查最终文本的产品验收无法观察这些行为。
+- **保留应用插件，只删除它的 bin。** 不予采纳：隐藏的组装仍会重复显式的 headless profile，并掩盖测试叶节点挂载了哪些服务。
+
+## 后果
+
+这是有意为之的破坏性变更。`dsh-cli-demo`、它的 `--output-format` 选项以及对 `@deepseek-ai/dsh-cli-demo/src/cli.ts` 的导入都不再可解析。本变更不提供公开的事件流替代接口；调用方使用 `dsh run` 执行一次性任务，需要结构化自动化时则必须选择现有的协议接口。
+
+仓库通过仅供测试的基础设施保留后端回放覆盖，产品冒烟测试和 built-bin 验收则运行 `dsh run`。只有当独立的一次性包负责一套真正独立、带版本且不能归产品启动器所有的协议时，它才可以重新引入；第二种命令写法或输出 shim 并不足以构成理由。
+
+## 验证
+
+聚焦的 Loader 冒烟测试在源码模式和由普通 Node 启动的构建模式下覆盖显式组装，快照测试对比其规范 JSONL 和持久化日志，产品验收覆盖 `dsh run`，文档检查及生成图谱／目录门禁则拒绝对已移除包的活跃引用。冻结的 Agent Note 归档保留为历史证据，不会被重写。
