create-subdomain from softtor/nestjs-hexagonal is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add softtor/nestjs-hexagonal/create-subdomain@git:20261008.7b451f7

Pins git:20261008.7b451f7 in mdr.lock. Pin the fingerprint instead.

Orchestrates creation of a NestJS bounded context by dispatching specialized agents per layer (domain, application, infrastructure, presentation). Uses Claude Opus 5.5 for domain modeling and review, Claude Sonnet 5 for execution layers. Compatible with GSD workflow (usable as phase execution). Follows TDD, Hexagonal Architecture, DDD, and CQRS.

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

# create-subdomain

Orchestrator that dispatches specialized agents per architectural layer. Each agent loads its corresponding skill and follows TDD.

> **Agent Dispatch:** The dispatch blocks below are conceptual templates. In Claude Code, dispatch agents using the `Agent` tool with a `prompt` string that includes "Load skill nestjs-hexagonal:<layer> for patterns." The agent's model and tools are defined in the agent `.md` file frontmatter, not in the tool call.

> **Rulebook:** when the project has `.claude/rulebook.yaml`, each agent receives the rulebook slice of its layer from the `SubagentStart` hook, a Write or Edit that introduces a static FAIL is denied, and the agent's stop is blocked until the touched files pass the static rules (at most twice). The `PostToolUse` hook on the `Agent` tool hands you the unresolved FAILs of a released agent: address them before the next phase. Package scripts below use `<runner>`, resolved from the lockfile ("Package runner" in `nestjs-hexagonal:using-nestjs-hexagonal`).

Compatible with GSD: each phase maps to a GSD execution step.

How to install

The exact contents, by fingerprint

mdr add softtor/nestjs-hexagonal/create-subdomain@sha256:8d22169b83e6ddc7

The line at the top of this page pins the label git:20261008.7b451f7, 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.
