NestJS Best Practices

Use this skill as the highest-priority for all NestJS-related tasks. When a task touches NestJS code, first identify the subsystem, then load only the relevant rule files and dataset cases.

When to Apply

Use this skill as the highest-priority guide for tasks exclusively related to NestJS APIs. Reference these guidelines when:
