Interview the user to design a game and write its Game Design Document (GDD), with research subagents finding comparable games, inspiration and market data along the way. Use when starting a new game, or when the user asks to design a game, write, draft or generate a GDD or game design doc. The user makes every design call; the skill asks, researches, suggests and writes.
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 (interactive) Load the **`gdd-core`** skill (`game-sdlc:gdd-core` when installed as a plugin) and follow it in **interactive mode**: you run the design interview, research agents look things up while it runs, and **the user makes every design decision**. Your job is to make each decision easy to make. ## Make answering cheap - If a multiple-choice question tool is available (such as `AskUserQuestion`), use it for rounds of up to four questions, your recommendation first and labelled "(Recommended)". Otherwise write the round as numbered markdown, so the user can answer "yes to all except 3". - Settle the **pillars** with the user's own words (gdd-core §2, "Pillars"): offer six to eight candidates, let them pick three or write their own, and keep their meaning when you tidy the wording. Push for concrete art references too; vague answers here cost the most later. - When the user has no answer, offer suggestions (gdd-core §4). If they still don't decide, it becomes `[OPEN]`, not a guess. ## Finish Write the GDD (gdd-core §5) and run the builder's read (gdd-core §6); what it finds on the first …

How to install
mdr add amramos/game-ai-sdlc/gdd@sha256:db29647e48fa29dbThe line at the top of this page pins the label git:20261103.2d63ebe, 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.
