env-validation

SKILL.md

Validate environment variables on server start and before builds. Catch missing or invalid variables early with clear error messages.

Some environment variables are read internally by packages rather than passed as arguments. To catch missing variables early instead of at runtime, import your configs in instrumentation.ts:

The side-effect imports trigger configSchema validation immediately when the server starts. If any required environment variable is missing, the server fails to start with a clear error rather than failing later when the code path is executed.

在服务器启动时和构建之前验证环境变量。通过清晰的错误消息尽早发现丢失或无效的变量。 来源：andrelandgraf/fullstackrecipes。
