  "content": "# 概述\n\nClaude Code 是由 Anthropic 官方推出的命令行 AI 编程助手，基于 Claude 模型，能够理解项目上下文、生成代码、解释代码和执行 Git 操作。\n\n## 安装\n\n```bash\n# macOS/Linux\nnpm install -g @anthropic-ai/claude-code\n\n# 或使用 Homebrew\nbrew install claude\n\n# 验证安装\nclaude --version\n```\n\n## 权限配置\n\nClaude Code 需要明确的权限才能执行敏感操作：\n\n### 权限级别\n\n| 操作 | 默认权限 | 说明 |\n|------|---------|------|\n| 读取文件 | 自动 | 可读取所有文件 |\n| 写入文件 | 需要确认 | 每次写入需用户确认 |\n| 执行命令 | 需要确认 | 终端命令需确认 |\n| Git 操作 | 需要确认 | commit/push 等需确认 |\n\n### 配置权限\n\n```bash\n# 允许所有命令自动执行\nclaude --dangerously-permit-commands all\n\n# 允许特定目录\nclaude --allowed-directory /path/to/project\n\n# 只读模式\nclaude --read-only\n```\n\n## 核心命令\n\n### /help - 帮助\n\n```bash\nclaude\n/help  # 显示所有可用命令\n```\n\n### /lsp - 代码理解\n\n```bash\n# 搜索代码中的函数或变量\n/lsp find readFile\n\n# 解释代码片段\n/lsp explain src/utils.js\n```\n\n### /web - 网络搜索\n\n```bash\n/web 如何在 React 中使用 hooks\n```\n\n### /commit - Git 提交\n\n```bash\n/commit  # 自动分析改动并生成 commit message\n```\n\n## MCP 集成\n\nClaude Code 支持 Model Context Protocol，可连接外部工具：\n\n```json\n// ~/.claude/settings.json\n{\n  \"mcpServers\": {\n    \"filesystem\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@anthropic/mcp-server-filesystem\", \"/path/to/dir\"]\n    },\n    \"github\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@anthropic/mcp-server-github\"]\n    }\n  }\n}\n```\n\n## 最佳实践\n\n1. **CLAUDE.md**：在项目根目录创建 CLAUDE.md 定义项目规范\n2. **权限控制**：生产环境使用只读模式\n3. **上下文限制**：大项目使用 /clear 清理上下文\n\n## 参考资料\n\n- [Claude Code 官方文档](https://code.claude.com/docs)\n- [Claude Code GitHub](https://github.com/anthropics/claude-code)\n",
