Produces game.md, systems-index.md, and art-direction.md, or runs as discussion-only.\"\nargument-hint: \"[<hint> | discuss]\"\nuser-invocable: true\nallowed-tools: Read, Glob, Grep, Write, Edit, Agent, AskUserQuestion\n---\n\n# Brainstorm\n\nThis skill explores a game concept through open-ended designer interview.\nSpawn `gat-designer` for design reasoning and `gat-artist` for visual direction.\nPick questions from the angle table below — follow the conversation, not a script.\n\n## Phase 1: Resolve Mode\n\n- If argument is `discuss` → Mode: `discuss` (no files written, exploration only)\n- If argument is a hint or empty → Mode: `design` (produces foundational design docs and global art direction)\n\nCheck whether `gat/overview/game.md`, `gat/overview/systems-index.md`, or\n`gat/overview/art-direction.md` already exist. If so, note them — the interview may\nrefine or replace existing decisions instead of starting from scratch.\n\n## Phase 2: The Interview\n\n### Core Rules\n\n- **One question at a time.** Never batch. Wait for the answer before the next question.\n- **Provide a recommended answer** with each question. Explain the design reasoning.\n- **Prefer open-ended questions.** Let the user type free-form responses. Reserve\n  `AskUserQuestion` (multiple-choice) for when you are presenting concrete solution\n  options and need the user to pick one. Most of the interview should be dialogue,\n  not forms.\n- **Pick angles, don't follow steps.** Use the angle table as a menu. Jump to\n  whatever dimension is most useful next — chase what's interesting or ambiguous.\n- **If a question can be answered by reading existing design files, read them\n  instead of asking.**\n- **Spawn `gat-designer`** when you need a design reasoning pass: drafting a core\n  loop, proposing systems, evaluating a trade-off, or checking consistency.\n- **Spawn `gat-artist`** when visual identity needs synthesis: art references,\n  palette, readability, asset groups, production standards, or conflicts between\n  style and gameplay clarity.\n\n### Drilling into Vague Ideas\n\nWhen the user has a fuzzy idea — about the whole game or a single system — your\njob is to make it concrete through relentless, curious questioning. This is the\ncore of the interview.\n\n**How to drill:**\n\n- When the user says something vague (\"combat should feel impactful\"), ask what\n  specifically makes it impactful — is it animation, sound, damage numbers,\n  controller rumble, enemy reaction, time-to-kill? Keep asking until the\n  abstraction bottoms out in concrete mechanics.\n- When the user proposes a system, ask about its boundaries. What does it NOT\n  do? What system owns the adjacent responsibility? A system without edges is\n  still fuzzy.\n- When the user describes a player experience (\"I want the player to feel\n  lost\"), ask what the game does to create that feeling. What does the player\n  see, hear, and do? What information is withheld? What mechanics produce the\n  emotion?\n- When the user references another game (\"like Dark Souls but...\"), isolate what\n  exactly they want to keep and what they want to change. The reference is a\n  shortcut — unpack it.\n- Ask about edge cases and failure states. What happens when the player ignores\n  the system? What happens when they optimize it to the extreme? The answers\n  reveal whether the system is understood or still hazy.\n- Ask about the player's moment-to-moment decisions. If the user can't describe\n  what choices the player makes inside the system, the system isn't clear yet.\n- If an answer opens three new questions, pick the most foundational one first.\n  Resolve dependencies before details.\n\n**Signals that something is still vague and needs more drilling:**\n\n- The user uses abstract adjectives without mechanics behind them (\"fun\",\n  \"smooth\", \"deep\", \"cool\")\n- A system is named but its inputs, outputs, and rules are undefined\n- Two systems have overlapping or unclear boundaries\n- The user can describe what the system IS but not what the player DOES in it\n- Numbers are absent where they matter (how many? how long? how much?)\n\n### Seed Extraction\n\nIf a concept hint was provided, first spawn `gat-designer` to extract what the\nhint already answers. Briefly summarize what's established so the user can\nconfirm or correct before diving in. Skip if no hint.\n\n### Interview Angles\n\nPick questions from any angle below. There is no fixed order — follow the\nthread that matters most at each moment. The table is a palette, not a checklist.\n\n| # | Angle | Purpose | Example prompts |\n|---|-------|---------|-----------------|\n| 1 | **Genre & Style** | Establish the game's design identity and reference points | What genre(s) does this live in? What games should it feel like mechanically? Real-time or turn-based? 2D or 3D? Single-player, co-op, or competitive? |\n| 2 | **Visual Direction** | Establish the global art identity that will become `art-direction.md` | What should the game look like at a glance? Which art references fit or should be avoided? What palette, shape language, camera, readability, and production constraints matter? |\n| 3 | **Core Player Verb** | Pin down the primary action the player repeats | What does the player actually DO moment-to-moment — shoot, build, explore, talk, craft, steer, command? What makes that action satisfying? |\n| 4 | **Target Feeling** | Define the emotional experience | What should the player feel during play — tension, mastery, wonder, power, relaxation, social connection, fear, curiosity? When do they feel it most? |\n| 5 | **Fantasy & Role** | Clarify who the player is in the world | What fantasy does the game fulfill? Who is the player — hero, commander, survivor, creator, investigator, merchant? |\n| 6 | **Scope & Constraints** | Set boundaries early | Rough scope (jam, indie, commercial)? Platform? Timeline? Team size? Content rating? Hard constraints? Any visual production constraints like pixel art, low-poly, UI-heavy, asset reuse, or resolution limits? |\n| 7 | **Core Loop** | Map the repeatable cycle that drives engagement | What's the 30-second loop? The 5-minute loop? The session loop? What pulls the player back in? |\n| 8 | **Systems & Mechanics** | Explore what systems the game needs | What systems does the core loop imply? Which are essential vs. nice-to-have? What does each system depend on? |\n| 9 | **Progression & Goals** | Define how the player grows and what they strive for | Short-term goals? Long-term goals? Skill tree or gear-based? Linear or branching? How does difficulty ramp? |\n| 10 | **Economy & Resources** | Map currencies, sinks, and sources | What resources does the player manage? How are they earned and spent? Is there inflation risk? |\n| 11 | **Risk & Reward** | Balance tension against payoff | What does the player risk losing? What do they gain for taking risks? Is failure interesting or just punishing? |\n| 12 | **Player Agency** | How much control and choice the player has | Where do players make meaningful choices? Are choices tactical (moment-to-moment) or strategic (long-term)? Emergent or scripted? |\n| 13 | **Feedback & Juice** | How the game communicates back to the player | How does the player know they did something right? What visual/audio hooks sell the actions? Screen shake, particles, sound? Which of those hooks should drive the global art direction? |\n| 14 | **Onboarding & Clarity** | How the player learns the game | Tutorial or discovery? How do you teach without lecturing? What's the first thing a new player does? What must be readable instantly in the UI or scene? |\n| 15 | **Narrative & World** | Story, setting, and tone | Is there a story? Player-driven or authored? What's the tone? How does the world reinforce the mechanics and visual identity? |\n| 16 | **Multiplayer & Social** | Other humans in the experience | Cooperative, competitive, or solo with social features? Synchronous or asynchronous? How do players interact? |\n| 17 | **Replayability & Depth** | What keeps players coming back | Procedural generation, build variety, difficulty modes, secrets? What's different on run #2 vs. run #50? |\n| 18 | **Accessibility** | Who can play and how | Difficulty options? Color independence? Remappable controls? Reaction-time accommodations? What visual signals must not rely on color alone? |\n| 19 | **Monetization** | Business model (if applicable) | Premium, F2P, subscription? If F2P, what's sold and does it affect gameplay? Any dark patterns to avoid? |\n| 20 | **Platform & Controls** | Input method and platform constraints | Mouse/keyboard, controller, touch? How many buttons does the design assume? Platform-specific constraints? |\n| 21 | **Content Volume** | How much stuff the game needs | How many levels, enemies, items, abilities? Is content hand-crafted, procedural, or both? What's the MVP slice? Which asset groups must be planned globally? |\n\n### Navigating the Interview\n\n- **Start where the energy is.** If the user leads with a mechanic, start at\n  Systems. If they describe a feeling, start at Target Feeling. If they mention\n  a reference game, start at Genre & Style.\n- **Drill, don't move on.** When the user gives a vague or high-level answer,\n  stay on that thread. Ask the follow-up that forces them to be specific. See\n  \"Drilling into Vague Ideas\" above — this is where most of the value comes from.\n- **Dive when something is interesting.** A throwaway answer about \"the world is\n  post-apocalyptic\" might open a rich thread about Narrative & World, Economy\n  (scarcity), or Fantasy & Role. Follow it.\n- **Ask open-ended, resolve with options.** Most questions should be free-form\n  dialogue — the user types their thoughts. Use `AskUserQuestion` only when you\n  have 2-3 concrete design proposals and need the user to choose among them (e.g.\n  picking a core loop direction, choosing between two system architectures).\n- **Spawn `gat-designer` mid-interview** when you need to synthesize answers\n  into a concrete proposal (core loop draft, system list, trade-off analysis).\n  Present what the agent returns, then ask about it.\n- **Spawn `gat-artist` mid-interview** when the visual identity is too vague or\n  conflicting. Ask for a concise art-direction proposal: references, palette,\n  shape language, readability priorities, asset groups, and production limits.\n  Present the proposal, then ask the user what to keep or change.\n- **Loop back naturally.** If a later answer contradicts an earlier assumption,\n  point it out and resolve the tension. Don't pretend consistency exists when it\n  doesn't.\n- **Know when to stop.** The interview has covered enough when:\n  - The core loop is clear and the user can describe it in their own words\n  - The system list is named with rough dependencies\n  - The global visual direction has references, palette or mood, readability priorities, and asset group strategy\n  - Scope boundaries are set\n  - The user starts repeating themselves rather than adding new information\n\n## Phase 3: Write or Summarize\n\n### If Mode is `design`\n\nBefore writing, summarize what's been decided across gameplay, systems, scope,\nand visual direction. Ask:\n\n> \"Ready to write the design docs?\"\n> Options: `Yes, write them` / `Let me keep discussing`\n\nIf yes, read templates:\n- `.claude/docs/templates/design/game-overview.md`\n- `.claude/docs/templates/design/systems-index.md`\n- `.claude/docs/templates/design/global-art.md`\n\n**Step 1** — Spawn `gat-designer` to write both foundational design files in one pass:\n- `gat/overview/game.md`\n- `gat/overview/systems-index.md`\n\nPass all interview answers, the confirmed system list with dependencies, and\nthe game overview and systems index templates. \n\nInstruct the designer to populate the **Key Design Decisions** section in `game.md`: \nrecord each foundational choice as a short paragraph, and add a **Why:** note when \nthe rationale or rejected alternatives need to be stated — drawing from the interview's \ntension-re","tagline":"Brainstorm a game idea through one-question-at-a-time designer interviews.
