infrastructure skillA
infrastructure is agent-read markdown (skill) from softtor/nestjs-hexagonal: Use when creating infrastructure layer artifacts for a NestJS bounded context — Prisma repositories, in-memory repositories (testing), model mappers, NestJS module wiring, adapters (port implementations), or event handler infrastructure. Repository is pure persistence with no event dispatch..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Infrastructure Layer
Infrastructure wires the domain to the outside world: databases, event buses, HTTP frameworks, and external services. It is the only layer allowed to import NestJS decorators and Prisma.
## Directory Structure

How to install
mdr add softtor/nestjs-hexagonal/infrastructure@git:20260921.8a9939bmdr add softtor/nestjs-hexagonal/infrastructure@sha256:5bf05eabf7befdfbPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
