NestJS Skills: Features, Scaling and Performance

A free, MIT-licensed agent skill for selecting and implementing NestJS runtime features, API and error contracts, security, testing, operational reliability, and performance improvements. It starts by inspecting the actual repository, installed versions, deployment context, and measured baseline.

Covers middleware, guards, pipes, interceptors, exception filters, validation, transport-specific error mapping, timeouts and cancellation, authentication and authorization, caching, queues, scheduling, idempotency, backpressure, and graceful shutdown. Focused references also cover CI/CD, containers, Kubernetes, observability, incident recovery, and rollout/rollback planning.

The workflow chooses framework primitives by lifecycle and diagnoses the limiting resource before optimizing. Performance claims require representative before-and-after measurements. It checks instructions and authorization before changes, preserves user work, and reconciles overlapping skill responsibilities.

For NestJS backends with a SKILL.md-compatible agent and appropriate repository tooling. Infrastructure, cloud services, external tools, and credentials are not included. Actual file changes, tests, network use, infrastructure operations, and environment access depend on the requested task and host permissions. It is not intended for frontend-only performance or non-NestJS services.
