斜線命令提供了一種使用以 / 開頭的特殊命令來控制 Claude Code 會話的方法。這些命令可以透過 SDK 發送,以執行清除對話歷史、壓縮訊息或獲取幫助等操作。
Claude Agent SDK 在系統初始化訊息中提供有關可用斜線命令的資訊。在會話開始時存取此資訊:
import { query } from "@anthropic-ai/claude-agent-sdk";
for await (const message of query({
prompt: "Hello Claude",
options: { maxTurns: 1 }
})) {
if (message.type === "system" && message.subtype === "init") {
console.log("Available slash commands:", message.slash_commands);
// Example output: ["/compact", "/clear", "/help"]
}
}透過在提示字串中包含斜線命令來發送它們,就像普通文字一樣:
/compact - 壓縮對話歷史/compact 命令透過總結較舊的訊息同時保留重要上下文來減少對話歷史的大小:
/clear - 清除對話/clear 命令透過清除所有先前的歷史來開始新的對話:
除了使用內建的斜線命令外,您還可以建立自己的自訂命令,這些命令可透過 SDK 使用。自訂命令定義為特定目錄中的 markdown 檔案,類似於子代理的配置方式。
自訂斜線命令根據其範圍儲存在指定的目錄中:
.claude/commands/ - 僅在當前專案中可用~/.claude/commands/ - 在您的所有專案中可用每個自訂命令都是一個 markdown 檔案,其中:
.md 副檔名)成為命令名稱建立 .claude/commands/refactor.md:
Refactor the selected code to improve readability and maintainability.
Focus on clean code principles and best practices.這會建立 /refactor 命令,您可以透過 SDK 使用。
建立 .claude/commands/security-check.md:
---
allowed-tools: Read, Grep, Glob
description: Run security vulnerability scan
model: claude-3-5-sonnet-20241022
---
Analyze the codebase for security vulnerabilities including:
- SQL injection risks
- XSS vulnerabilities
- Exposed credentials
- Insecure configurations一旦在檔案系統中定義,自訂命令就會自動透過 SDK 可用:
自訂命令支援使用佔位符的動態參數:
建立 .claude/commands/fix-issue.md:
---
argument-hint: [issue-number] [priority]
description: Fix a GitHub issue
---
Fix issue #$1 with priority $2.
Check the issue description and implement the necessary changes.在 SDK 中使用:
自訂命令可以執行 bash 命令並包含其輸出:
建立 .claude/commands/git-commit.md:
---
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)
description: Create a git commit
---
## Context
- Current status: !`git status`
- Current diff: !`git diff HEAD`
## Task
Create a git commit with appropriate message based on the changes.使用 @ 前綴包含檔案內容:
建立 .claude/commands/review-config.md:
---
description: Review configuration files
---
Review the following configuration files for issues:
- Package config: @package.json
- TypeScript config: @tsconfig.json
- Environment config: @.env
Check for security issues, outdated dependencies, and misconfigurations.在子目錄中組織命令以獲得更好的結構:
.claude/commands/
├── frontend/
│ ├── component.md # Creates /component (project:frontend)
│ └── style-check.md # Creates /style-check (project:frontend)
├── backend/
│ ├── api-test.md # Creates /api-test (project:backend)
│ └── db-migrate.md # Creates /db-migrate (project:backend)
└── review.md # Creates /review (project)子目錄出現在命令描述中,但不會影響命令名稱本身。
建立 .claude/commands/code-review.md:
---
allowed-tools: Read, Grep, Glob, Bash(git diff:*)
description: Comprehensive code review
---
## Changed Files
!`git diff --name-only HEAD~1`
## Detailed Changes
!`git diff HEAD~1`
## Review Checklist
Review the above changes for:
1. Code quality and readability
2. Security vulnerabilities
3. Performance implications
4. Test coverage
5. Documentation completeness
Provide specific, actionable feedback organized by priority.建立 .claude/commands/test.md:
---
allowed-tools: Bash, Read, Edit
argument-hint: [test-pattern]
description: Run tests with optional pattern
---
Run tests matching pattern: $ARGUMENTS
1. Detect the test framework (Jest, pytest, etc.)
2. Run tests with the provided pattern
3. If tests fail, analyze and fix them
4. Re-run to verify fixes透過 SDK 使用這些命令:
