+## 设计抽象
+
+`device-pod` 可以理解成云端可拥有和调度的一张嵌入式实验台。云端拥有的是 `device-pod` 这个逻辑能力单元，不是直接拥有某一块裸板、某一根探针或某一台用户 PC。只要 profile 能把 `deviceTarget`、`debugInterface`、`projectWorkspace` 和 `ioInterface` 四要素绑定清楚，code agent 就可以围绕同一个 `devicePodId` 完成源码修改、构建、下载、复位、状态读取和 I/O 观察，从而覆盖嵌入式开发的完整闭环。
+
+四要素的物理落点可以不同，也可以复用同一个硬件实体的不同能力：
+
+- `deviceTarget` 是被调试和被验证的目标设备。
+- `debugInterface` 提供下载、烧录、复位、debug probe 状态和芯片识别等调试能力。
+- `projectWorkspace` 承载源码、工程、Keil/GCC 等工具链和编译产物。
+- `ioInterface` 提供 AI、AO、DI、DO、UART、截图、日志和其他实时或近实时观测/控制能力。
+
+`device-pod` 因此是逻辑打包关系，而不是一对一物理设备关系。一个 DAPLink/MKLink 类探针可以同时拆出 `debugInterface` 的 SWD/CMSIS-DAP 能力和 `ioInterface` 的 UART 能力；同一个 `device-pod` 也可以把该探针与调试 box、USB 摄像头、串口工具或厂商上位机组合起来，共同形成对同一个 `deviceTarget` 的完整访问能力。
+
+## 平台化服务模式
+
+`device-pod` 把设备目标和访问能力封装成统一逻辑单元后，HWLAB 可以在同一技术模型上承载多种交付模式。不同模式的差异主要在于 `deviceTarget`、probe、workspace、云平台和运维责任分别由谁提供，但对 code agent 和用户界面暴露的仍应是稳定的 `devicePodId`、能力边界、锁、job、trace 和 evidence。
+
+- **Device Pod 租赁**：HWLAB 运营常用开发板、调试探针、I/O 工具和 workspace 的设备机房，用户无需自备硬件即可在云端基于真实原型开发；软件验证后可以自行找硬件工程师，或委托平台侧硬件工程师继续绘制 PCB。
+- **用户 PCB 托管**：用户已经完成 PCB 或样机，委托 HWLAB 托管该 `deviceTarget`，平台提供或代管 probe、I/O 工具、workspace 和 `device-pod` 运行面，用户通过云端继续开发、测试和迭代。
+- **用户自有设备接入**：用户保留自己的 `deviceTarget`、debug probe 和 I/O probe，只接入 HWLAB 云；平台把这些资源通过 profile/gateway/device-host-cli 抽象为 `device-pod`，供用户自己远程开发。
+- **委托开发与运维**：在用户自有设备接入的基础上，用户可以授权平台内其他开发者、维护人员或自动化 code agent 围绕同一个 `device-pod` 进行软件开发、调试、故障复现、在线维护和验收。
+- **私有 HWLAB 云部署**：用户公司内部部署自有 HWLAB 云和自有设备池，平台提供安装、升级、运维和最佳实践支持；设备、数据和权限留在用户私有环境内，`device-pod` 模型保持一致。

+description: Use the HWLAB internal device-pod CLI from a HWLAB code agent runner to operate a profiled target workspace, debug probe, and I/O probe through hwlab-gateway and device-host-cli.
+version: 0.1.0-mvp
+---
+
+# Device Pod CLI
+
+Skill(cli-spec)
+
+Scope: this skill is only for HWLAB-internal code agent runners inside the
+HWLAB runtime, such as `/workspace/hwlab` sessions running from the G14 DEV or
+PROD images. It does not apply to external UniDesk developer workspaces or
+third-party machines; those environments must not treat this skill as a general
+hardware control contract.
+
+Use this skill when the task mentions `device-pod-cli`, `device-pod`,
+`device-host-cli`, HWLAB device-pod profile files, Keil build/download through a
+device pod, debug probe control, or I/O probe reads such as UART boot logs.
+
+## Runtime Contract
+
+- The preinstalled CLI entrypoint is
+  `node /app/skills/device-pod-cli/scripts/device-pod-cli.mjs`.
+- The canonical implementation is `/app/tools/device-pod-cli.mjs`; the skill
+  script is only a stable preinstalled wrapper for code agent runners.
+- The packaged Windows host CLI asset is
+  `/app/skills/device-pod-cli/assets/device-host-cli.mjs`. It is bundled with
+  this skill so a runner can send the exact tested host-side CLI to a new
+  Windows hardware PC before the first device-pod operation.
+- Profiles are read from `.device-pod/<devicePodId>.json` in the current code
+  agent workspace, or from `DEVICE_POD_PROFILE` when a task explicitly points to
+  a profile file.
+- The CLI calls HWLAB cloud-api `hardware.invoke.shell`, which dispatches to an
+  outbound `hwlab-gateway` session and then to the user PC side
+  `device-host-cli`. Do not call gateway, serial ports, Keil, pyOCD, DAPLink, or
+  Windows shell directly when the profiled device-pod path is available.
+- `device-host-cli` is expected to be self-contained on the user PC. Keil,
+  serial-monitor, mklink, and other skills can be implementation references, but
+  are not runtime dependencies of this HWLAB runner skill.
+- `device-host-cli` is not just a copied preinstall script. It is the hot
+  development tool that HWLAB internal code agents, including DeepSeek-backed
+  runners, may keep improving on the target Windows workspace when hardware,
+  Keil, probe, UART, or filesystem operations are not smooth enough. Hot fixes
+  are expected whenever host-side behavior is awkward or missing; validate them
+  through the real device-pod/gateway route first, then copy the result back into
+  the HWLAB repo asset for the next CI/CD preinstall.
+
+## Windows Host CLI Bootstrap
+
+Do not run a separate installer. To bring up a new Windows hardware PC, send the
+packaged asset to the target workspace through the existing cmd passthrough path,
+then start it through the same cmd passthrough path.
+
+Target layout:
+
+```text
+<windows-workspace>\tools\device-host-cli.mjs
+<windows-workspace>\.device-pod\<devicePodId>.json
+```
+
+When the UniDesk Windows maintenance route is available, the file transfer may
+use the same remote channel that backs cmd passthrough. In HWLAB coder images,
+`/app/tools/tran.mjs` is the stable contract entrypoint;
+`/app/tools/hwlab-gateway-tran.mjs` is only the compatible explicit wrapper for
+the same transport. If the compatible wrapper exists but `/app/tools/tran.mjs`
+is missing, report a CI/CD preinstall gap instead of adding a device-pod
+workaround. In HWLAB k8s runner pods, `tran.mjs` auto-selects the in-cluster
+`hwlab-cloud-api.<namespace>.svc.cluster.local:6667` API endpoint; outside k8s it
+falls back to local `127.0.0.1:6667`, and non-standard deployments may still pass
+`--api-base-url`. `tran.mjs upload` uses bounded base64 chunks tuned for the
+Windows cmd passthrough limit; do not raise the chunk size above the documented
+default to hide slow transfers. If upload/download becomes awkward again, fix
+`tran.mjs` or the gateway transport first.
+
+```text
+node /app/tools/tran.mjs <gatewaySessionId>:/d/Work/HWLAB-workspace upload /app/skills/device-pod-cli/assets/device-host-cli.mjs tools/device-host-cli.mjs
+node /app/tools/tran.mjs <gatewaySessionId>:/d/Work/HWLAB-workspace cmd -- node tools\\device-host-cli.mjs health
+```
+
+When only HWLAB gateway `hardware.invoke.shell` is available, send the asset
+bytes as bounded base64 chunks through cmd/PowerShell into
+`tools\device-host-cli.mjs`, then verify with:
+
+```text
+node tools\device-host-cli.mjs health
+```
+
+After that, `device-pod-cli` should use the profile's `hostCli`, normally
+`node tools\device-host-cli.mjs`, and should not depend on any Windows skill
+directory at runtime.
+
+## Host CLI Hot Development
+
+When a profiled operation is awkward or missing, prefer improving the Windows
+workspace copy of `tools\device-host-cli.mjs` instead of bypassing the device-pod
+model with arbitrary cmd snippets. The intended loop is:
+
+```text
+edit tools\device-host-cli.mjs in the Windows device-pod workspace
+node tools\device-host-cli.mjs health
+node tools\device-host-cli.mjs <new named operation>
+node /app/skills/device-pod-cli/scripts/device-pod-cli.mjs <devicePodId>:... <same operation>
+copy the validated change back to skills/device-pod-cli/assets/device-host-cli.mjs
+```
+
+The host CLI should stay self-contained and named-operation oriented: add
+`debug-probe launch-flash` or `io-probe uart/1 read-after-launch-flash` style
+device semantics, not a generic shell escape. If gateway/cmd transfer itself is
+the friction, fix `tran.mjs` or the gateway transport separately instead of
+embedding transport workarounds into `device-host-cli`.
+
+## Commands
+
+All commands emit JSON and must remain short-running. Use `build start` /
+`build status` and `download start` / `download status` style host jobs for
+long operations instead of holding one gateway request open.
+
+```text

+```
+
+## Safety
+
+- Mutating operations such as workspace patching, download, reset,
+  `launch-flash`, `read-after-launch-flash`, and I/O write require
+  `--approved --reason <text>` before the CLI dispatches anything.
+- `io-probe:/inner/...` is intentionally distinct from external physical I/O
+  paths such as `io-probe:/uart/1`; do not use internal target state as evidence
+  for external UART/GPIO observations.
+- Keep the gateway as transport only. Do not add a generic `cmd` operation to
+  `device-pod-cli`; add a named device-pod operation instead.
+- If the CLI returns `profile-missing`, `profile-invalid`, or
+  `approval-required`, fix that blocker first rather than guessing a default
+  device or falling back to arbitrary shell commands.
