Authors a web-game concept — pitch, core loop, MDA, mechanics, progression and economy, content scope, visual/audio direction, feasibility (engine, frame/memory/load budgets on mobile web, networking), accessibility, metrics, prototype plan — into docs/specs/game-concept.md; `gate` records the prototype go/no-go. Use when starting a game, for 'game idea', 'core loop', 'is the prototype fun'.
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 Concept
Reply in the project conversation language (CLAUDE.md → Language); code, identifiers, paths and commit messages stay in English.
Template `.claude/docs/templates/game-concept.md`. Reference `threejs-webgames.md`. In the commands below, `<hooks>` is `.claude/hooks/` in copy mode and `${CLAUDE_PLUGIN_ROOT}/hooks/` in plugin mode.
## Phase 1: Pitch and loop
Questions: genre, the player's "verb", session (minutes), platform (mobile web first?), single/multiplayer, references. Three core-loop variants with "why it is fun to repeat".
## Phase 2: Mechanics, progression, content
Rules with parameters (mark which live in data, not code); a difficulty-curve table; MVP volume vs full version.
## Phase 3: Feasibility
Engine with justification (3D → three.js, WebGPU with WebGL2 fallback; 2D → PixiJS/Phaser; versions from `threejs-webgames.md`); budget: 16.6 ms frame, draw calls, memory, first load on 4G; networking (multiplayer → server-authoritative on Go, tick rate); saves; **spikes** to test risks (e.g. "1000 instances on a mid-range phone").
`threejs-engineer`/`web-game-engineer` via Task — risk assessment for their part (in parallel).

How to install
mdr add gonimar/claude-web-studio/game-concept@sha256:6fd420b7e6ef7988The line at the top of this page pins the label git:20260927.d019450, 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.
