Resolved above — use as-is. No block → defaults in .claude/docs/config-resolution.md.

--review overrides review_mode; store it for all gate spawns this run. See .claude/docs/director-gates.md for the full check pattern. Individual gate definitions live in .claude/docs/director-gates/[gate-id].md — the spawned agent reads its own gate file; do not read it in the parent session.

Every AskUserQuestion call follows .claude/docs/automation-modes.md (collaborative asks always · guided major-only · autonomous logs and proceeds; automation_always_ask categories always prompt).

docs.density — it controls per-section depth, where workflow controls which sections exist. modes.rigor sets both together; set docs.density explicitly to vary depth alone: terse = pillar bullets + concept bullets; balanced = pillars + concept with brief rationale (default); thorough = pillars + concept + extensive rationale + alternatives. Apply it to every section you author.

Tier branch — check `workflow` FIRST

The workflow tier resolved above governs this skill's output:

standard / full → run the full flow ("When this skill is invoked" through Phase 5 and the concept-document generation). No change.
minimal → run the Lean Brief flow immediately below and STOP — skip Phases 1–5, the director gates (CD-PILLARS / AD-CONCEPT-VISUAL / TD-FEASIBILITY / PR-SCOPE), and the full-length concept document entirely. Output is the one-page design/game-brief.md, not game-concept.md.

Lean Brief flow (`workflow: minimal` only)

A jam / small-scope session: capture the load-bearing thinking in one page, then get to code. Keep prompting light — a few exchanges, not fifteen. Author from the one-page template .claude/docs/templates/game-brief.md (6 required fields + 2 one-liners). If design/game-brief.md already exists, read it and resume/refine rather than restart.

Concept — from the argument hint (or one quick open question if none), propose 2–3 one-line concepts (verb-first or mashup, per Phase 2's techniques). One AskUserQuestion to pick or combine — the only guaranteed creative prompt.
Fill the brief fields conversationally (not one prompt each):
- One-sentence pitch — the excited one-liner.
- Core loop — the 2–4 step cycle the player repeats.
- MVP — the ruthlessly short feature list that makes it the game (each becomes a story downstream). If it runs past ~7, push back on scope.
- Out of scope — what they're deliberately NOT building.
- Build order — sequence to build the MVP, risky / core-fun thing first.
- Who it's for / what they feel and Art & audio direction — one line each (offer, don't force). Present the filled brief back in full for a single confirmation.
Write approval — AskUserQuestion: "Brief is ready. May I write it to design/game-brief.md?" → [A] Yes — write it / [B] Revise a field first. On [B], revise the named field, show before/after, re-ask; repeat until [A]. Then write design/game-brief.md from the template, creating directories as needed. Honor modes.automation for this write as elsewhere in the framework.
Next steps (short — this is the point). Read engine.name from project.yaml first and list /setup-engine only if it is absent or empty:
1. (only when engine.name is absent or empty) "/setup-engine — configure the engine (required before code)"
2. "/create-stories — turn the brief's MVP list into implementable stories. The epic is implicit at minimal; there is no separate /create-epics or /sprint-plan — the brief's build order is the plan."
3. "/dev-story — first line of game code"
Why the condition. /start's minimal path runs /setup-engine before /brainstorm, and /setup-engine Section 2 states that a missing brief is expected because the brief is authored afterwards. Listing engine setup unconditionally here tells a user who just followed that path to go back and redo step one — the only skill in the four-step path that assumes it runs first. Then output a one-line summary (pitch + MVP feature count + design/game-brief.md).

Verdict: COMPLETE — game brief created; next stop is code. Do NOT run Phases 1–5, spawn any director gate, or write game-concept.md at this tier.

When this skill is invoked (standard / full tier — minimal uses the Lean Brief flow above):

Parse the argument for an optional genre/theme hint (e.g., roguelike, space survival, cozy farming). If open or no argument, start from scratch.
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)
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.

This decision asks regardless of modes.automation. Concept selection is the creative heart of /brainstorm and has no defensible autonomous default — there is no algorithmic way to pick which creative direction resonates with the user. Per .claude/docs/automation-modes.md, treat this site as exempt (it overrides the mode the same way automation_always_ask categories do).

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.

Never pressure toward a choice — let them sit with it.

Phase 3: Core Loop Design

For the chosen concept, use structured questioning to build the core loop. The core loop is the beating heart of the game — if it isn't fun in isolation, no amount of content or polish will save the game.

30-Second Loop (moment-to-moment):

Ask these as AskUserQuestion calls — derive the options from the chosen concept, don't hardcode them:

Core action feel — prompt: "What's the primary feel of the core action?" Generate 3-4 options that fit the concept's genre and tone, plus a free-text escape (I'll describe it).
Key design dimension — identify the most important design variable for this specific concept (e.g., world reactivity, pacing, player agency) and ask about it. Generate options that match the concept. Always include a free-text escape.

After capturing answers, analyze: Is this action intrinsically satisfying? What makes it feel good? (Audio feedback, visual juice, timing satisfaction, tactical depth?)

5-Minute Loop (short-term goals):

What structures the moment-to-moment play into cycles?
Where does "one more turn" / "one more run" psychology kick in?
What choices does the player make at this level?

## Tier branch — check `workflow` FIRST

The `workflow` tier resolved above governs this skill's output:

- **`standard` / `full`** → run the full flow ("When this skill is invoked" through
  Phase 5 and the concept-document generation). No change.
- **`minimal`** → run the **Lean Brief flow** immediately below and **STOP** — skip
  Phases 1–5, the director gates (CD-PILLARS / AD-CONCEPT-VISUAL / TD-FEASIBILITY /
  PR-SCOPE), and the full-length concept document entirely. Output is the one-page
  `design/game-brief.md`, not `game-concept.md`.

### Lean Brief flow (`workflow: minimal` only)

A jam / small-scope session: capture the load-bearing thinking in one page, then get
to code. Keep prompting light — a few exchanges, not fifteen. Author from the
one-page template `.claude/docs/templates/game-brief.md` (6 required fields + 2
one-liners). If `design/game-brief.md` already exists, read it and resume/refine
rather than restart.

1. **Concept** — from the argument hint (or one quick open question if none), propose
   **2–3 one-line concepts** (verb-first or mashup, per Phase 2's techniques). One
   `AskUserQuestion` to pick or combine — the only guaranteed creative prompt.
2. **Fill the brief fields** conversationally (not one prompt each):
   - **One-sentence pitch** — the excited one-liner.
   - **Core loop** — the 2–4 step cycle the player repeats.
   - **MVP** — the ruthlessly short feature list that makes it *the game* (each becomes
     a story downstream). If it runs past ~7, push back on scope.
   - **Out of scope** — what they're deliberately NOT building.
   - **Build order** — sequence to build the MVP, risky / core-fun thing first.
   - **Who it's for / what they feel** and **Art & audio direction** — one line each
     (offer, don't force).
   Present the filled brief back in full for a single confirmation.
3. **Write approval** — `AskUserQuestion`: "Brief is ready. May I write it to
   `design/game-brief.md`?" → `[A] Yes — write it` / `[B] Revise a field first`. On
   [B], revise the named field, show before/after, re-ask; repeat until [A]. Then
   write `design/game-brief.md` from the template, creating directories as needed.
   Honor `modes.automation` for this write as elsewhere in the framework.
4. **Next steps** (short — this is the point). **Read `engine.name` from
   `project.yaml` first and list `/setup-engine` only if it is absent or empty:**
   1. *(only when `engine.name` is absent or empty)* "`/setup-engine` — configure
      the engine (required before code)"
   2. "`/create-stories` — turn the brief's MVP list into implementable stories. The
      epic is implicit at `minimal`; there is no separate `/create-epics` or
      `/sprint-plan` — the brief's build order is the plan."
   3. "`/dev-story` — first line of game code"

   > **Why the condition.** `/start`'s `minimal` path runs `/setup-engine`
   > *before* `/brainstorm`, and `/setup-engine` Section 2 states that a missing
   > brief is expected because the brief is authored afterwards. Listing engine
   > setup unconditionally here tells a user who just followed that path to go
   > back and redo step one — the only skill in the four-step path that assumes
   > it runs first.
   Then output a one-line summary (pitch + MVP feature count + `design/game-brief.md`).

Verdict: **COMPLETE** — game brief created; next stop is code. Do NOT run Phases 1–5,
spawn any director gate, or write `game-concept.md` at this tier.

When this skill is invoked (`standard` / `full` tier — `minimal` uses the Lean Brief
flow above):

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.

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

### 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.

**This decision asks regardless of `modes.automation`.** Concept selection
is the creative heart of `/brainstorm` and has no defensible autonomous
default — there is no algorithmic way to pick which creative direction
resonates with the user. Per `.claude/docs/automation-modes.md`, treat
this site as exempt (it overrides the mode the same way
`automation_always_ask` categories do).

**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.

Never pressure toward a choice — let them sit with it.

---

### Phase 3: Core Loop Design

For the chosen concept, use structured questioning to build the core loop.
The core loop is the beating heart of the game — if it isn't fun in
isolation, no amount of content or polish will save the game.

**30-Second Loop** (moment-to-moment):

Ask these as `AskUserQuestion` calls — derive the options from the chosen concept, don't hardcode them:

1. **Core action feel** — prompt: "What's the primary feel of the core action?" Generate 3-4 options that fit the concept's genre and tone, plus a free-text escape (`I'll describe it`).

2. **Key design dimension** — identify the most important design variable for this specific concept (e.g., world reactivity, pacing, player agency) and ask about it. Generate options that match the concept. Always include a free-text escape.

After capturing answers, analyze: Is this action intrinsically satisfying? What makes it feel good? (Audio feedback, visual juice, timing satisfaction, tactical depth?)

**5-Minute Loop** (short-term goals):
- What structures the moment-to-moment play into cycles?
- Where does "one more turn" / "one more run" psychology kick in?
- What choices does the player make at this level?
