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 `.claude/docs/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 `AskUserQuestion`** at key decision points throughout brainstorming:
- Constrained taste questions (genre preferences, scope, team size)
- Concept selection ("Which 2-3 concepts resonate?") after presenting options
- Direction choices ("Develop further, explore more, or prototype?")
- Pillar ranking after concepts are refined
Write full creative analysis in conversation text first, then use
`AskUserQuestion` to capture the decision with concise labels.
Professional studio brainstorming principles to follow:
- Withhold judgment — no idea is bad during exploration
- Encourage unusual ideas — outside-the-box thinking sparks better concepts
- Build on each other — "yes, and..." responses, not "but..."
- Use constraints as creative fuel — limitations often produce the best ideas
- Time-box each phase — keep momentum, don't over-deliberate early
---
### Phase 1: Creative Discovery
Start by understanding the person, not the game. Ask these questions
conversationally (not as a checklist):
**Emotional anchors**:
- What's a moment in a game that genuinely moved you, thrilled you, or made
you lose track of time? What specifically created that feeling?
- Is there a fantasy or power trip you've always wanted in a game but never
quite found?
**Taste profile**:
- What 3 games have you spent the most time with? What kept you coming back?
*(Ask this as plain text — the user must be able to type specific game names freely.
Do NOT put this in an AskUserQuestion with preset options.)*
- Are there genres you love? Genres you avoid? Why?
- Do you prefer games that challenge you, relax you, tell you stories,
or let you express yourself? *(Use `AskUserQuestion` for this — constrained choice.)*
**Practical constraints** (shape the sandbox before brainstorming).
Bundle these into a single multi-tab `AskUserQuestion` with these exact tab labels:
- Tab "Experience" — "What kind of experience do you most want players to have?" (Challenge & Mastery / Story & Discovery / Expression & Creativity / Relaxation & Flow)
- Tab "Timeline" — "What's your realistic development timeline?" (Weeks / Months / 1-2 years / Multi-year)
- Tab "Dev level" — "Where are you in your dev journey?" (First game / Shipped before / Professional background)
Use exactly these tab names — do not rename or duplicate them.
**Synthesize** the answers into a **Creative Brief** — a 3-5 sentence
summary of the person's emotional goals, taste profile, and constraints.
Read the brief back and confirm it captures their intent.
---
### Phase 2: Concept Generation
Using the creative brief as a foundation, generate **3 distinct concepts**
that each take a different creative direction. Use these ideation techniques:
**Technique 1: Verb-First Design**
Start with the core player verb (build, fight, explore, solve, survive,
create, manage, discover) and build outward from there. The verb IS the game.
**Technique 2: Mashup Method**
Combine two unexpected elements: [Genre A] + [Theme B]. The tension between
the two creates the unique hook. (e.g., "farming sim + cosmic horror",
"roguelike + dating sim", "city builder + real-time combat")
**Technique 3: Experience-First Design (MDA Backward)**
Start from the desired player emotion (aesthetic goal from MDA framework:
sensation, fantasy, narrative, challenge, fellowship, discovery, expression,
submission) and work backward to the dynamics and mechanics that produce it.
For each concept, present:
- **Working Title**
- **Elevator Pitch** (1-2 sentences — must pass the "10-second test")
- **Core Verb** (the single most common player action)
- **Core Fantasy** (the emotional promise)
- **Unique Hook** (passes the "and also" test: "Like X, AND ALSO Y")
- **Primary MDA Aesthetic** (which emotion dominates?)
- **Estimated Scope** (small / medium / large)
- **Why It Could Work** (1 sentence on market/audience fit)
- **Biggest Risk** (1 sentence on the hardest unanswered question)
Present all three. Then use `AskUserQuestion` to capture the selection.
**CRITICAL**: This MUST be a plain list call — no tabs, no form fields. Use exactly this structure:
```
AskUserQuestion(
prompt: "Which concept resonates with you? You can pick one, combine elements, or ask for fresh directions.",
options: [
"Concept 1 — [Title]",
"Concept 2 — [Title]",
"Concept 3 — [Title]",
"Combine elements across concepts",
"Generate fresh directions"
]
)
```
Do NOT use a `tabs` field here. The `tabs` form is for multi-field input only — using it here causes an "Invalid tool parameters" error. This is a plain `prompt` + `options` call.From swl521/Codex-Game-Studios, MIT.
