# 环境变量管理器
## 触发条件
当用户要求管理环境变量、.env 文件、配置同步、Secrets 检查时激活。
## 工作流程
### 1. 扫描项目
- 检测所有 `.env*` 文件(.env / .env.local / .env.development / .env.production)
- 默认只提取变量名、来源文件和是否为空;真实值必须脱敏,不写入报告或终端输出
- 扫描代码中引用的环境变量(`process.env.XXX` / `os.environ['XXX']` / `os.getenv('XXX')`)
- 识别静态扫描中未发现引用的变量(仅作为待人工确认候选)
- 识别已使用但未定义的变量(缺失配置)
### 2. 校验分析
- 检查必填变量是否有默认值
- 验证 URL 格式、端口号范围、布尔值格式
- 检测硬编码的敏感信息(API Key / Token / Password)
- 对比 .env.example 与实际 .env 文件的差异
### 3. 生成/修复
- 生成 `.env.example` 模板(仅包含变量名和说明,不含真实值)
- 生成 `.env.schema.json`(结构化校验规则)
- 检测到硬编码密钥时,建议迁移到环境变量
- 生成 `dotenv` 加载配置(针对不同框架)
### 4. 同步
- 在 monorepo 中同步共享环境变量
- 生成 Docker Compose 的 env_file 配置
- 生成 CI/CD 的 Secrets 配置清单
## 输出格式
### .env.example 示例
```bash
# 应用配置
APP_NAME=my-app
APP_ENV=development # development | staging | production
APP_PORT=3000 # 服务端口 (1-65535)
APP_DEBUG=true # 调试模式
# 数据库
DB_HOST=localhost
DB_PORT=5432
DB_NAME=mydb
DB_USER= # 必填
DB_PASSWORD= # 必填,生产环境请使用 Secrets
# 第三方服务
REDIS_URL= # 必填,格式:redis://host:port
JWT_SECRET= # 必填,至少 32 位随机字符串
```

📋 环境变量分析报告
==================
✅ 定义且使用: 12 个
⚠️ 定义未使用: 2 个(S3_BUCKET, OLD_API_KEY)
❌ 使用未定义: 1 个(SENDGRID_API_KEY)
🔒 硬编码敏感信息: 1 处(src/auth.js:23)
建议:
1. 人工确认 S3_BUCKET 和 OLD_API_KEY 是否被 CI、部署脚本或动态代码引用,再决定是否删除
2. 在 .env 中添加 SENDGRID_API_KEY
3. 将 src/auth.js:23 的硬编码 token 迁移到环境变量
```
## 安全检查清单
- [ ] 扫描和报告只展示变量名及脱敏状态,不回显真实 Secret
- [ ] `.env` 已添加到 `.gitignore`
- [ ] `.env.example` 存在且与代码同步
- [ ] 无硬编码的 API Key / Token / Password
- [ ] 生产环境使用 Secrets 管理(GitHub Secrets / AWS SSM / Vault)
- [ ] JWT_SECRET / ENCRYPTION_KEY 足够随机(32+ 字符)
- [ ] 数据库密码不在日志中输出
## 修改边界
- 不要自动删除或改写真实 `.env`;先展示差异并取得用户确认。
- “未使用”只代表静态扫描没有发现,仍需检查 CI、容器、部署平台和动态变量访问。
- 不把生产 Secret 复制到 `.env.example`、Schema、日志、Issue 或聊天输出中。
## 常见陷阱
- **Next.js**:只有 `NEXT_PUBLIC_` 前缀的变量会暴露给客户端,后端专用变量不要加此前缀
- **Docker**:构建时的 ARG 和运行时的 ENV 是不同的,不要混淆
- **Create React App**:`.env` 中的变量必须以 `REACT_APP_` 开头才会被注入
- **Vite**:使用 `VITE_` 前缀暴露变量给客户端
- **monorepo**:根目录的 `.env` 不会自动被子包读取,需要显式配置
## 框架适配
| 框架 | 客户端前缀 | 配置文件 | 加载方式 |
|------|-----------|---------|---------|
| Next.js | NEXT_PUBLIC_ | .env.local | 自动 |
| Vite | VITE_ | .env | 自动 |
| CRA | REACT_APP_ | .env | 自动 |
| Nuxt | NUXT_PUBLIC_ | .env | 自动 |
| Vue CLI | VUE_APP_ | .env | 自动 |

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.

Copies are not installs. Installation counts require a reported successful installation; they are not a blanket quality guarantee.
This page exposes the same decision, trust, audit, use-case, and install signals through the Registry API, so agents can rank this skill without scraping the UI.
