Use when building or structuring a NestJS backend — feature modules, providers and DI wiring, provider scopes and request-lifecycle order, where to bind guards/pipes/interceptors/filters, and testing with Test.createTestingModule. NOT a bare Express/Fastify service with no DI (that is `nodejs`), NOT framework-agnostic REST design (that is `api-design`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NestJS Build server-side Node apps the way NestJS intends: feature modules, providers wired through the DI container, controllers, and a cross-cutting layer bound at a deliberate scope. This skill is about Nest-specific mechanics — how DI scopes resolve, what order the request lifecycle runs in, where to bind guards/pipes/interceptors/filters, and how to test it with `Test.createTestingModule`. ## Not this — route instead - Bare Express/Fastify/`http` service, no `@Module`/`@Injectable` → `../nodejs/SKILL.md`. Nest starts the moment the DI container appears. - REST resource modeling, versioning, status codes, idempotency (framework-agnostic) → `../api-design/SKILL.md`. Nest is where you *implement* those decisions. - Designing the schema / writing queries / migrations → `../prisma-orm/SKILL.md`. *Injecting* a repo or `DataSource` provider stays here; designing the table does not. - Generic JS/TS test infra (Jest config, coverage thresholds, monorepo) → `../testing-web/SKILL.md`. The Nest harness (`TestingModule`, `overrideProvider`, Supertest bootstrap) stays here. ## Mental model …

How to install
mdr add ericrisco/rsc-harness/nestjs@sha256:9aedff493c45e8f3The line at the top of this page pins the label git:20260729.baa11e7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
