Turn a vague idea into a buildable plan — genre, scope, core loop, mechanics, art direction — written as a 1-page brief to .summer/GameSoul.md.
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
# /brainstorm-game — Decide What Game to Build
## Overview
Most game projects fail because they were never scoped. This skill turns "I want to make a game" into a 1-page brief that names the pitch, the core loop, three mechanics max, the art direction, and the scope (jam / vertical slice / full game). The brief lands at `.summer/GameSoul.md` — the file Summer's onboarding pipeline and every future Summer skill reads on first turn.
**Core principle:** Constrain ruthlessly. A buildable bad idea beats an un-buildable great idea. Three mechanics, one art direction, one scope. Anything else gets parked in a "Later" list.
## Steps
### 1. Open with the one question
Ask exactly this and wait:
> One sentence — what kind of game do you want to make?
Don't pre-pitch genres. Don't list options. Read what they say. The first sentence is signal.
If they freeze ("I don't know"), offer 4 reference points only:
…Read the whole file at its exact version.
How to install
mdr add summerengine/summer/brainstorm-game@sha256:f8d928c12956e1c9The line at the top of this page pins the label git:20261010.4ade947, 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.
