The shared method behind gdd and gdd-handsoff — the design tree a GDD has to cover, rounds over its frontier, research agents for comparables and the market, suggestions versus decisions, the GDD template with its markers, glossary, worked example and first playable, and a blind builder's read before handover. Loaded by those two skills; not called directly by the user.
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
# GDD: the shared method Turns an idea into a GDD that agents can build from. The method is the same in both modes; only **who answers the rounds** differs: - **interactive** (`gdd`): the user answers every round; - **hands-off** (`gdd-handsoff`): you answer with one outside reviewer per round, and the user reacts to a short summary. Either way, decisions are made by whoever answers the round. Facts are looked up by research agents, never asked. **The owner's taste profile.** Before the first round, read it by `taste-profile` §1 (`game-sdlc:taste-profile` when installed as a plugin): - **Never open `taste.md` yourself; run §1's command**, which prints only the Never lines. Do this before reading anything else about the profile. - If it prints `MISSING`, offer the profile (its §5). - You, running the rounds, and every drafter keep only the Never lines. - Interactive: before a round that holds a question the owner's by nature (the pillars, tone, art style, the hook, interface identity) goes out, a judge with the whole profile checks its recommendations. Other rounds go out without it. - Hands-off: the round reviewer judges with it, every round. …

How to install
mdr add amramos/game-ai-sdlc/gdd-core@sha256:9b53cdca598e9edcThe line at the top of this page pins the label git:20261103.cac3e99, 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.
