Guided game concept ideation — from zero idea to a structured game concept document. Uses professional studio ideation techniques, player psychology frameworks, and structured creative exploration.
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
When this skill is invoked:
1. **Parse the argument** for an optional genre/theme hint (e.g., `roguelike`,
`space survival`, `cozy farming`). If `open` or no argument, start from
scratch. Also resolve the review mode (once, store for all gate spawns this run):
1. If `--review [full|lean|solo]` was passed → use that
2. Else read `production/review-mode.txt` → use that value
3. Else → default to `lean`
See `docs/framework/director-gates.md` for the full check pattern.
2. **Check for existing concept work**:
- Read `design/gdd/game-concept.md` if it exists (resume, don't restart)
- Read `design/gdd/game-pillars.md` if it exists (build on established pillars)
3. **Run through ideation phases** interactively, asking the user questions at
each phase. Do NOT generate everything silently — the goal is **collaborative
exploration** where the AI acts as a creative facilitator, not a replacement
for the human's vision.
**Use `question`** at key decision points throughout brainstorming:
- Constrained taste questions (genre preferences, scope, team size)
- Concept selection ("Which 2-3 concepts resonate?") after presenting options

How to install
mdr add striderza/opencodegamestudios/concept-brainstorm@sha256:b74ffacdd9f3e026The line at the top of this page pins the label git:20260622.695134d, 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.
