Author and own ONE system's design document (the A–K SYSTEM GDD) at .unikit/gamedesign/systems/SYS-<slug>.md — the depth layer of the GDD, single-system scope. Create the skeleton and walk the collaborative section-cycle to write its parameters, rules, formulas, and acceptance criteria ("detail the combat system", "write the GDD for the inventory system", "fill in the rest of this system doc", "spec out the parameters of X"), AND revise it after approval under the delta discipline…
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
# Game Design — Per-System GDD (Authoring & Revision) Own **one system's design document** at `.unikit/gamedesign/systems/SYS-<slug>.md` — eleven sections (A–K) plus any domain section-packs. This skill owns the **system zone** (`gd-principles` → Zone Ownership): the **full lifecycle** of a `SYSTEM.md` lives here — **create** the skeleton, **fill** its placeholders, and **revise** approved content (Tuning / Tweak / Rework) under the delta discipline. There is no separate editor skill. It never creates the master spec or the map, and never edits `GAME.md` content — that is `unikit-gd-spec`; player-action flows are `unikit-gd-flow`'s. **User questions.** Right before your first question to the user, not earlier, read `.unikit/system/user-questions.md` once and ask every question as it says, with the question tool of your agent (`AskUserQuestion`). If the file cannot be read, print `WARN [questions] user-questions contract missing — asking with the question tool` and still ask with that tool, the recommended option first. ## Language Awareness — BLOCKING PRE-REQUISITE **BEFORE producing ANY output**, silently read `.unikit/system/LANGUAGE_RULES.md` …

How to install
mdr add nintendadev/unikit-ai/unikit-gd-system@sha256:d41a691a0680e875The line at the top of this page pins the label v1.0, 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.
