This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
domain-modeling from nerviz-ai/nerviz is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Details the domain and application layer of an already-designed use case — aggregate, value objects, invariants, ports, and events — into the `10-domain.md` partial. Use when the request involves modeling the domain, defining an aggregate or value object, designing a use case's ports, or detailing a spec already created by `use-case-design`. Piece of the `/new-feature` pipeline: requires `00-use-case.md` in the given folder and stops without it.
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
## Available specs
!`find "${CLAUDE_PROJECT_DIR:-.}/docs/use-cases" -mindepth 1 -maxdepth 1 -type d -name 'UC-*' 2>/dev/null | sort`
Empty above → none yet, run `/use-case-design` first. (`find`, not an `ls` glob: under zsh an unmatched glob
aborts the command before any fallback runs.)
## Target

# Domain Modeling
Details the **interior** of a use case: what the mother spec named, this skill gives
shape to. Signatures, types, invariants, and where each lives.
**Entry rule: without a mother spec, there's nothing to detail.** This skill reads
`docs/use-cases/UC-NNN-<slug>/00-use-case.md` and treats it as a contract. Without
that file, it stops and tells you to run `/use-case-design` — modeling a domain from a
loose request reinvents the boundary the mother spec exists to fix.
**Exit rule: it doesn't write code.** It emits `10-domain.md`. The Java classes come
from the executor agent, which reads the partial and the `templates/` exemplars.
## How it's invoked
Two paths, and both matter: `/domain-modeling` by hand, or chained by `/new-feature` once
that orchestrator exists. That's why it does **not** carry

How to install
mdr add nerviz-ai/nerviz/domain-modeling@sha256:75213de2b983f364The line at the top of this page pins the label git:20261014.7301cd9, 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.
