Use when pinning down domain terminology, building a ubiquitous language or project glossary, disambiguating overloaded or vague terms, or maintaining a CONTEXT.md — or when another skill needs to sharpen the domain model. Do NOT use for recording architectural decisions or for writing implementation specs.
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
# Domain Modeling Actively build and sharpen the project's domain model as you design — the *active* discipline of challenging terms, inventing edge-case scenarios, and writing the glossary down the moment it crystallises. Merely *reading* `CONTEXT.md` for vocabulary is not this skill (that's a one-line habit any skill can do); this skill is for when you're **changing** the model, not just consuming it. **Why it pays off:** an opinionated `CONTEXT.md` is a persistent, shared language. Once the domain has canonical names, variables/functions/files get named consistently, the codebase is easier for an agent to navigate, and the agent spends fewer tokens on thinking because it has a more concise language. The cost is one glossary entry; the payoff compounds every session. *Adapted from [mattpocock/skills](https://github.com/mattpocock/skills) (MIT) — the `domain-modeling` skill, with its ADR format left out.* ## File structure Most repos have a single context — one `CONTEXT.md` at the repo root: ``` / ├── CONTEXT.md ← the glossary └── src/ ``` …

How to install
mdr add jasonm4130/claude-skills/domain-modeling@sha256:557fd5b0b4c32404The line at the top of this page pins the label git:20260914.e17e16a, 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.
