Great day to be outside!\n```\n\n## 先决条件\n\n在开始之前，请确保具备：\n\n* 已安装并完成身份验证的 **GitHub Copilot CLI**（Node.js、Python 和 .NET SDK 会自动提供该 CLI——请参阅 [默认设置（随附的 CLI）](/zh/enterprise-cloud@latest/copilot/how-tos/copilot-sdk/setup/bundled-cli)）。 对于 Go、Java 和 Rust 而言，这是必需的，除非使用它们的应用层级 CLI 捆绑功能。）\n* 首选语言运行时：\n  * **Node.js** 20+ 或 **Python** 3.11+ 或 **Go** 1.24+ 或 > **Rust** 1.94+ 或 **Java** 17+ 或 **.NET** 8.0+\n\n验证 CLI 是否正常工作：\n\n```bash\ncopilot --version\n```\n\n## 步骤 1：安装 SDK\n\n<div class=\"ghd-codetabs\">\n<div class=\"ghd-codetab\" data-lang=\"typescript\" data-label=\"TypeScript\"><div class=\"ghd-codetab-fallback-label\" role=\"heading\" aria-level=\"3\">TypeScript</div>\n\n首先，创建新目录并初始化项目：\n\n```bash\nmkdir copilot-demo && cd

class=\"ghd-codetab-fallback-label\" role=\"heading\" aria-level=\"3\">Rust</div>\n\n首先，创建新的二进制箱：\n\n```bash\ncargo new copilot-demo && cd copilot-demo\n```\n\n然后安装示例使用的 SDK 和直接依赖项：\n\n```bash\ncargo add github-copilot-sdk --features derive\n# Used by #[tokio::main] and tokio::spawn\ncargo add tokio --features rt-multi-thread,macros\n# Used by custom-tool parameter derives later in this

<version>${copilot.sdk.version}</version>\n</dependency>\n```\n\n**Gradle**—添加到您的`build.gradle`：\n\n```groovy\nimplementation 'com.github:copilot-sdk-java:${copilotSdkVersion}'\n```\n\n</div>\n\n</div>\n\n## 步骤 2：发送第一条消息\n\n创建新文件并添加以下代码。 这是使用 SDK 的最简单方法-大约 5 行代码。\n\n<div class=\"ghd-codetabs\">\n<div class=\"ghd-codetab\" data-lang=\"typescript\" data-label=\"TypeScript\"><div class=\"ghd-codetab-fallback-label\" role=\"heading\" aria-level=\"3\">TypeScript</div>\n\n创建 `index.ts`：\n\n```typescript\nimport {

Copilot使用参数发送工具调用请求\n2. SDK 运行你的处理函数\n3. 结果被发回给 Copilot\n4. Copilot将结果合并到其响应中\n\n## 接下来会发生什么？\n\n现在，你已获得基础知识，下面提供了更强大的功能来探索：\n\n### 连接到 MCP 服务器\n\nMCP（模型上下文协议）服务器提供预构建的工具。 连接到 GitHub 的 MCP 服务器，让 Copilot 能够访问存储库、问题和拉取请求：\n\n```typescript\nconst session = await client.createSession({\n    mcpServers: {\n        github: {\n            type: \"http\",\n            url: \"https://api.githubcopilot.com/mcp/\",\n        },\n    },\n});\n```\n\n📖\n\\*\\*\n[将 MCP 服务器与 GitHub Copilot SDK 配合使用](/zh/enterprise-cloud@latest/copilot/how-tos/copilot-sdk/features/mcp)\\*\\* - 了解本地服务器与远程服务器、所有配置选项和故障排除。\n\n### 创建自定义代理\n\n定义特定任务的专用 AI 角色：\n\n```typescript\nconst session = await client.createSession({\n    customAgents: [{\n        name: \"pr-reviewer\",\n        displayName: \"PR Reviewer\",\n        description: \"Reviews pull requests for best practices\",\n        prompt: \"You are an expert code reviewer. Focus on security, performance, and maintainability.\",\n    }],\n});\n```\n\n> \\[!TIP]\n> 还可以在会话配置中设置 `agent: \"pr-reviewer\"` ，以便从一开始就预先选择此代理。 有关详细信息，请参阅 [自定义代理和子代理编排](/zh/enterprise-cloud@latest/copilot/how-tos/copilot-sdk/features/custom-agents#selecting-an-agent-at-session-creation) 。\n\n### 自定义系统消息\n\n通过追加说明来控制 AI 的行为和个性：\n\n```typescript\nconst session = await client.createSession({\n    systemMessage: {\n        content: \"You are a helpful assistant for our engineering team. Always be concise.\",\n    },\n});\n```\n\n若要进行更精细的控制，请使用 `mode: \"customize\"` 替代系统提示的各个部分，同时保留其余部分：\n\n```typescript\nconst session = await client.createSession({\n    systemMessage: {\n        mode: \"customize\",\n        sections: {\n            tone: { action: \"replace\", content: \"Respond in a warm, professional tone. Be thorough in explanations.\" },\n            code_change_rules: { action: \"remove\" },\n            guidelines: { action: \"append\", content: \"\\n* Always cite data sources\" },\n        },\n        content: \"Focus on financial analysis and reporting.\",\n    },\n});\n```\n\n可用章节 ID：`preamble`、`identity`、`tool_efficiency`、`tone`、`guidelines`、`environment_context`、`code_change_rules`、`safety`、`tool_instructions`、`custom_instructions`、`runtime_instructions`、`last_instructions`。\n\n`identity` 和 `tool_instructions` 属于*章节组*：它们将一组相关的子节作为一个整体进行处理。 使用`preamble`选项仅以标识前言为目标，而不影响其同级子节。\n\n每个替代都支持五个操作：`replace`、、`remove``append`、`prepend`和`preserve`。\n`preserve`操作是无操作，可使可单独寻址的节不受组级`remove`操作影响（例如，在删除`identity`组时保留`tone`相应的节）。 未知节 ID 会得到妥善处理：来自`replace`/`append`/`prepend`覆盖的内容将追加到附加说明中，`remove`其他相应覆盖将被静默忽略。\n\n有关 [TypeScript](https://github.com/github/copilot-sdk/tree/main/nodejs/README.md) 中的示例，请参阅特定于语言的 SDK README， [Python](https://github.com/github/copilot-sdk/tree/main/python/README.md)、[Go](https://github.com/github/copilot-sdk/tree/main/go/README.md)、[Rust](https://github.com/github/copilot-sdk/tree/main/rust/README.md)、[Java](https://github.com/github/copilot-sdk/tree/main/java/README.md)和[C#](https://github.com/github/copilot-sdk/tree/main/dotnet/README.md)。\n\n## 连接到外部 CLI 服务器\n\n默认情况下，SDK 会自动管理Copilot CLI 进程生命周期，根据需要启动和停止 CLI。 但是，还可以单独在服务器模式下运行 CLI，并让 SDK 连接到它。 这可用于：\n\n* **调试**：使 CLI 在 SDK 重启之间保持运行以检查日志\n* **资源共享**：多个 SDK 客户端可以连接到同一 CLI 服务器\n* **开发**：使用自定义设置或在不同的环境中运行 CLI\n\n### 在服务器模式下运行 CLI\n\n使用 `--headless` 标志在服务器模式下启动 CLI，并根据需要指定端口：\n\n```bash\ncopilot --headless --port 4321\n```\n\n如果未指定端口，CLI 将选择随机可用的端口。\n\n默认情况下，无头服务器仅接受来自环回 (`127.0.0.1`) 的连接，因此 SDK 必须在同一台机器上运行。 若要接受来自其他主机的连接（例如，在容器中或在单独的服务器上运行 CLI 时），请使用 `--host`以下命令绑定到非环回地址：\n\n```bash\n# Listen on all interfaces\ncopilot --headless --host 0.0.0.0 --port 4321\n```\n\n> \\[!WARNING]\n> 将无头服务器暴露在非回环地址上，会使任何能够路由到该地址的用户都可以访问该服务器。 将其与适合你的环境的网络控制（防火墙、专用网络、反向代理）和身份验证配对。\n\n### 将 SDK 连接到外部服务器\n\n在服务器模式下运行 CLI 后，使用“cli url”选项将 SDK 客户端配置为连接到它：\n\n<div

CLI 之间自动传播 [W3C 跟踪上下文](https://www.w3.org/TR/trace-context/) 。\n\n### 启用遥测\n\n创建客户端时，传入 `telemetry`（或 `Telemetry`）配置。 这是选择加入 — 无需单独的“enabled”标志。\n\n<div class=\"ghd-codetabs\">\n<div

exporterType: \"file\",\n  },\n});\n```\n\n### 跟踪上下文传播\n\n自动传播跟踪上下文 - 无需手动检测：\n\n* **SDK → CLI**：来自当前跨度/活动的 `traceparent` 和 `tracestate` 标头会包含在 `session.create`、`session.resume` 和 `session.send` RPC 调用中。\n* **CLI → SDK**：当 CLI 调用工具处理程序时，将传播 CLI 范围中的跟踪上下文，以便工具代码在正确的父范围下运行。\n\n📖\n\\*\\*\n[Copilot SDK 的 OpenTelemetry
