1. 斜杠命令
斜杠命令是 捷徑 用於常見任務。類型 / 在聊天中查看清單:
| 命令 | 功能 | 例如 |
|---|---|---|
/初始化 |
為專案建立自訂說明 | /初始化 (分析程式碼庫並建立 copilot-instructions.md) |
/修復 |
修復當前程式碼或錯誤 | /修復類型錯誤:無法讀取未定義的屬性“id” |
/測試 |
為程式碼產生單元測試 | UserService 類別的 /tests |
/文件 |
產生文件 | /doc 用於此文件中的所有匯出函數 |
/解釋 |
程式碼解釋 | /解釋#選擇 |
/清除 |
清除聊天記錄 | /清除 |
1.1. /init — 為項目設定 AI
最重要的 Slash 指令!運行 /初始化 開始在專案中使用 Copilot 時:
// Trong Chat view, gõ:
/init
// Copilot phân tích codebase và tạo:
// .github/copilot-instructions.md với:
// - Project structure description
// - Tech stack
// - Coding conventions phát hiện từ codebase
// - Testing patterns
// - Naming conventions
1.2. /fix — 快速修復
// Copy error từ terminal hoặc Problems panel:
/fix npm ERR! Could not resolve dependency:
npm ERR! peer react@"^17.0.0" from [email protected]
1.3. /tests — 自動產生測試
// Mở file cần test, rồi:
/tests for all public methods, include edge cases and error scenarios.
Use Jest with describe/it blocks.
2. 聊天參與者
聊天參與者(從 @)是特定領域的「專家」:
| 參加者 | 專業知識 | 何時使用 |
|---|---|---|
@工作空間 |
了解整個程式碼庫 | 詢問專案結構,尋找相關程式碼 |
@終端 |
終端命令 | 命令解釋,修復終端錯誤 |
@vscode |
VS 程式碼功能 | 詢問設定、快捷方式、擴展 |
2.1. @workspace — 程式庫專家
@workspace Where is the database connection configured in this project?@workspace How is error handling done across API routes? Show me the pattern.
@workspace What testing framework and patterns are used? Show examples.
2.2. @terminal — 終端助手
@terminal How to find all processes using port 3000 and kill them?@terminal Explain this command: find . -name "*.ts" -exec grep -l "TODO" {} ;
@terminal The last command failed with permission denied. How to fix?
2.3. @vscode — IDE 專家
@vscode How to configure auto-format on save for TypeScript files?@vscode What's the shortcut to split editor vertically?
@vscode How to create a launch.json for debugging Node.js?
3. 組合模式-真正的力量
結合斜線命令、參與者和上下文變數以獲得強大的提示:
模式 1:修復 + 上下文
/fix #terminalLastCommand
Look at #file:src/services/OrderService.ts and fix the failing test.
The error seems related to the mock setup.
模式 2:測試 + 檔案參考
/tests for #file:src/utils/validation.ts
Follow the same pattern as #file:tests/utils/string.test.ts
Include these scenarios: empty input, null, unicode, SQL injection attempts
模式3:工作區搜尋+實施
@workspace Find all API endpoints that don't have rate limiting.
Then add rate limiting middleware to each one, using the same
configuration as #file:src/middleware/rateLimit.ts
4. 建立個人提示庫
建立常用提示範本集合:
4.1.在專案中儲存提示文件
建立資料夾 .github/提示/ 有文件 .提示.md:
<!-- .github/prompts/new-api-endpoint.prompt.md -->
---
description: Create a new REST API endpoint
---
Create a new API endpoint for {{resource_name}}.
Requirements:
- CRUD operations (GET list, GET by id, POST, PUT, DELETE)
- Zod validation for request bodies
- Prisma queries following our repository pattern
- Error handling with our AppError class
- Authentication middleware on all routes
- Pagination for list endpoint (cursor-based)
Follow patterns in:
- Route: src/routes/userRoutes.ts
- Service: src/services/UserService.ts
- Schema: src/schemas/userSchema.ts
4.2.使用提示文件
在聊天中,參考提示檔:
#file:.github/prompts/new-api-endpoint.prompt.md
resource_name = "products"
5. 先進技術
5.1.負面提示
Create a user registration form.
DO NOT:
- Use any CSS framework (no Tailwind, no Bootstrap)
- Add client-side validation (we handle it server-side)
- Include social login buttons
- Use any external dependencies
5.2.輸出規格
Generate a database migration for adding an "orders" table.Output format:
- Prisma schema addition (for schema.prisma)
- SQL migration file (for manual review)
Seed data TypeScript file (5 sample records)
5.3.比較分析
I need a caching solution for our API responses. Compare these approaches with code examples for each: 1. In-memory cache (node-cache) 2. Redis cache 3. HTTP cache headers
For each, show: setup code, cache hit/miss handling, cache invalidation strategy. Recommend which to use for our use case: 100 RPS, data changes every 5 minutes.
六、總結
| 工具 | 前綴 | 最適合 |
|---|---|---|
| 斜線指令 | / |
快速操作:修復、測試、文件、初始化 |
| 聊天參與者 | @ |
領域專業:工作區、終端、vscode |
| 情境變數 | # |
附加特定上下文:文件、選擇、程式碼庫 |
| 提示文件 | .提示.md |
用於重複任務的可重複使用的模板 |
將這一切結合起來,你就擁有了一個 提示工具包 完成有效的 Vibe 編碼。從第 4 部分開始,我們將自訂和擴充 Copilot 的功能: 自訂指令、自訂代理程式和 MCP 伺服器。
