+title: "Xenon Interoperability"
+---
+
+[Xenon](https://github.com/xianyu-sheng/Xenon) is a terminal AI coding
+workspace. VeADK and Xenon both support directory-based `SKILL.md` files and
+standard MCP, so the same local Skill and MCP Server can be reused in both
+environments without converting it to a vendor-specific format.
+
+<Callout type="info">
+  This page covers component interoperability. It does not mean that VeADK
+  supports `Agent(runtime="xenon")`. Using Xenon as an inner VeADK runtime
+  requires a separate runtime adapter and event translation.
+</Callout>
+
+<Callout type="info">
+  The integration commands below require the published Xenon `v0.7.1` release
+  or later.
+</Callout>
+
+## Basic usage
+
+The [`codex_with_skill_and_mcp`](https://github.com/volcengine/veadk-python/tree/main/examples/codex_with_skill_and_mcp)
+example includes a weather Skill and a stdio MCP Server that exposes
+`get_weather`. Configure the same components in Xenon with these commands:
+
+```bash
+cd examples/codex_with_skill_and_mcp
+
+xenon skill install ./skills/weather-style --scope project --json
+xenon mcp add veadk-weather "$(command -v python)" --json -- ./mcp_server.py
+xenon integrations verify --connect-mcp --server veadk-weather --json
+```
+
+The verification command performs MCP `initialize`,
+`notifications/initialized`, and `tools/list`, but does not call a tool. A
+successful result reports one reachable server and one `get_weather` tool:
+
+```json
+{
+  "ok": true,
+  "checks": {
+    "mcp_connectivity": {
+      "reachable_server_count": 1,
+      "tool_count": 1
+    }
+  }
+}
+```
+
+Start `xenon` from the current project directory and ask for the weather in a
+city. Xenon loads the response format from the project Skill and obtains the
+weather data through the configured MCP Server.
+
+```text
+What is the weather in Beijing?
+```
+
+Remove the MCP configuration after the test:
+
+```bash
+xenon mcp remove veadk-weather --json
+```
+
+## Component mapping
+
+```mermaid
+flowchart LR
+    S["Local SKILL.md"] --> V["VeADK SkillToolset"]
+    S --> X["Xenon project Skill"]
+    M["stdio MCP Server"] --> V
+    M --> X
+```
+
+| Capability | VeADK | Xenon | Interoperability |
+| :-- | :-- | :-- | :-- |
+| Local Skill | `load_skill_from_dir` + `SkillToolset` | `xenon skill install` | Reuses `SKILL.md` and its resource directory directly |
+| stdio MCP | `MCPToolset` + `StdioServerParameters` | `xenon mcp add` | Reuses the command, arguments, and environment variables |
+| Ark model | `MODEL_AGENT_*` configuration | `ARK_*` configuration | API-compatible; credentials are managed separately |
+| Agent runtime | `adk`, `codex`, and `piagent` | Xenon engines | No `runtime="xenon"` adapter yet |
+
+## Integration checks
+
+External installers can read Xenon machine-readable contract before deciding
+where to write configuration:
+
+```bash
+xenon integrations describe --json
+xenon skill doctor --json
+xenon mcp doctor --json
+```
+
+The capability contract publishes Skill roots, MCP transports, and versioned
+commands, so an installer does not need to modify Xenon private YAML directly.
+See the [Xenon integration CLI](https://github.com/xianyu-sheng/Xenon/blob/main/docs/INTEGRATIONS.md)
+for the field-level contract.

+title: "Xenon 互操作"
+---
+
+[Xenon](https://github.com/xianyu-sheng/Xenon) 是终端 AI 编程工作区。VeADK 与
+Xenon 都支持目录式 `SKILL.md` 和标准 MCP，因此同一份本地 Skill 与 MCP Server
+可以在两个运行环境中复用，无需转换为厂商私有格式。
+
+<Callout type="info">
+  本页介绍组件互操作，不表示 VeADK 已支持 `Agent(runtime="xenon")`。Xenon 作为
+  VeADK 内层运行时需要独立的运行时适配与事件转换。
+</Callout>
+
+<Callout type="info">
+  以下集成命令需要已正式发布的 Xenon `v0.7.1` 或更高版本。
+</Callout>
+
+## 基本使用
+
+仓库中的 [`codex_with_skill_and_mcp`](https://github.com/volcengine/veadk-python/tree/main/examples/codex_with_skill_and_mcp)
+示例包含一个天气 Skill 和一个提供 `get_weather` 的 stdio MCP Server。以下命令把
+同一组组件配置到 Xenon：
+
+```bash
+cd examples/codex_with_skill_and_mcp
+
+xenon skill install ./skills/weather-style --scope project --json
+xenon mcp add veadk-weather "$(command -v python)" --json -- ./mcp_server.py
+xenon integrations verify --connect-mcp --server veadk-weather --json
+```
+
+验证命令执行 MCP `initialize`、`notifications/initialized` 和 `tools/list`，但不会
+调用工具。成功结果包含一个可达服务器和一个 `get_weather` 工具：
+
+```json
+{
+  "ok": true,
+  "checks": {
+    "mcp_connectivity": {
+      "reachable_server_count": 1,
+      "tool_count": 1
+    }
+  }
+}
+```
+
+从当前项目目录启动 `xenon`，然后询问城市天气。Xenon 从项目 Skill 根目录加载回答
+格式，并通过已配置的 MCP Server 获取天气数据。
+
+```text
+北京天气怎么样？
+```
+
+测试结束后可删除 MCP 配置：
+
+```bash
+xenon mcp remove veadk-weather --json
+```
+
+## 组件映射
+
+```mermaid
+flowchart LR
+    S["本地 SKILL.md"] --> V["VeADK SkillToolset"]
+    S --> X["Xenon 项目 Skill"]
+    M["stdio MCP Server"] --> V
+    M --> X
+```
+
+| 能力 | VeADK | Xenon | 互操作状态 |
+| :-- | :-- | :-- | :-- |
+| 本地 Skill | `load_skill_from_dir` + `SkillToolset` | `xenon skill install` | 直接复用 `SKILL.md` 与资源目录 |
+| stdio MCP | `MCPToolset` + `StdioServerParameters` | `xenon mcp add` | 复用命令、参数和环境变量 |
+| Ark 模型 | `MODEL_AGENT_*` 配置 | `ARK_*` 配置 | API 兼容，凭证分别管理 |
+| Agent runtime | `adk`、`codex`、`piagent` | Xenon 自身引擎 | 尚无 `runtime="xenon"` 适配 |
+
+## 集成检查
+
+外部安装器可以先读取 Xenon 的机器可读契约，再决定写入位置：
+
+```bash
+xenon integrations describe --json
+xenon skill doctor --json
+xenon mcp doctor --json
+```
+
+能力契约公开 Skill 根目录、MCP transport 和版本化命令，不需要直接修改 Xenon 的
+私有 YAML。详细字段见 [Xenon 外部集成 CLI](https://github.com/xianyu-sheng/Xenon/blob/main/docs/INTEGRATIONS.md)。
