Guess Who's AI? — Social Deduction Game

A multiplayer social deduction game powered by OceanBus P2P messaging. One host + 4-6 players. Some players are secretly AI. Find them before they blend in.

Game Rules (30 seconds)

text

Host creates a room. Players join.
Host secretly assigns each player: Human or AI.

Each round:
  1. Players take turns speaking (by number order)
  2. Everyone votes: "Who is the AI?"
  3. Most-voted player is eliminated — identity revealed
  4. Repeat until: all humans survive → Humans win
                all AIs survive → AIs win
                final 2: 1 human + 1 AI → Draw

Recommended: 5 players (3 humans + 2 AIs) for best balance.

All game messages are visible to the user. No data is sent without the player's explicit action.

---

Roster Integration

Player contacts are stored in the shared Roster (~/.oceanbus/roster.json) via node game.js add. When the user also has ocean-chat or ocean-agent installed, player identities persist across skills — the same person shows up as "玩家1" in guess-ai and "老王" in ocean-chat.

For contact management (merge duplicates, review autoDiscovery, etc.), use ocean-chat. guess-ai only uses Roster for storing/reading player identities.

How to Use This Skill

This ONE skill works for both host and player. Same install, different mode.

Host: Creating a Game

When the user wants to host a game:

Step 1 — Register & create room:

text

node game.js host 9527

Read the output. Room code is 9527. Tell the user to share this code with friends.

Step 2 — Wait for players: Periodically run node game.js check to see who has joined. Each player sends "加入" as their first message.

When a new "加入" arrives:

1. Assign the next available number (player1, player2, ... by join order)
2. Save to contacts: node game.js add 玩家N <their-OpenID>
3. Reply privately: node game.js send <OpenID> "【裁判】你的编号是: 玩家N"
4. Broadcast to all: node game.js send <name> "【裁判】玩家N 加入了游戏 — 当前 N 人"

Step 3 — Close registration & start: When the user says "start" (enough players, ideally 4-6):

1. Broadcast: send every player "【裁判】游戏开始 — 共N名玩家"
2. Proceed to role assignment.

Player: Joining a Game

When the user wants to join a game:

Step 1 — Join:

text

node game.js join 9527

This discovers the host via Yellow Pages and sends "加入".

Step 2 — Get your number: Run node game.js check. When you see "【裁判】你的编号是: 玩家N":

text

node game.js set-number N

Step 3 — Wait for game start: Keep checking messages. The host will broadcast status updates.

Host: Full Game Flow

After registration closes, follow this exact sequence:

Phase 1: Assign Roles

1. Randomly decide how many AIs (1-2, depending on player count).
   • 4 players → 1 AI
   • 5 players → 2 AIs
   • 6 players → 2 AIs
2. Randomly pick which players are AI.
3. Send to EACH player privately:
   • Human: node game.js send <name> "【裁判】你的身份是: 人类"
   • AI: node game.js send <name> "【裁判】你的身份是: AI"
4. Broadcast to all: "【裁判】身份已分配，请检查私信"

Phase 2: Generate Topic

IMPORTANT: Generate a conversation topic before round 1. Without a topic, players stare at a blank screen.

Topic prompt (use your LLM):

Generate a fun group chat topic. Requirements:

• Everyone can participate, no expertise needed
• Naturally reveals personal style (AI vs human differences emerge)
• Avoid politics, religion, sensitive topics
• Sound like a friend starting a chat, not a teacher
• Examples: "What skill would you instantly master if you could?"
• Examples: "What's the best purchase you made recently?"
• Examples: "If you didn't have to work, what would you do the first week?"
• Output: ONE sentence, no explanation.

Phase 3: Game Rounds (loop)

Each round has: SPEAK → VOTE → REVEAL.

SPEAK Phase

1. Broadcast: node game.js send <each-player> "【裁判】第N轮发言开始"
2. Broadcast topic (round 1 only): "【裁判】话题: <topic>"
3. Prompt player 1 privately: node game.js send 玩家1 "【裁判】轮到你发言了"
4. Wait. Periodically node game.js check.
5. When player 1's message arrives (you'll see 【1号】...):
   • Broadcast to ALL players: "【裁判】第N轮 · 玩家1发言: <exact content>"
   • Move to player 2.
6. Continue through all players in order.
7. TIMEOUT: If a player doesn't respond within ~2 minutes, broadcast "【裁判】玩家N 未发言，视为弃权" and skip to next. Do NOT eliminate them — they can rejoin next round.

Only relay the currently prompted player's speech. If other players send messages out of turn, ignore them (don't broadcast).

VOTE Phase

1. Broadcast to ALL alive players: node game.js send <each-alive-player> "【裁判】第N轮投票开始 — 请私信裁判你的选择"
2. Send to EACH alive player individually: node game.js send <name> "【裁判】请投票 — 你想投谁？"
3. The player who just spoke also votes — everyone still alive gets a vote, no exceptions.
4. Eliminated players do NOT receive vote prompts. Track who is alive.
5. Wait for votes. Run node game.js check to collect.
6. Players vote freely: "我投1号", "投第一个", "玩家1" — you understand them all.
7. TIMEOUT: If a player doesn't vote within ~1 minute, they abstain. Don't eliminate them.
8. Eliminated players cannot vote — if they try, ignore.
9. Count votes. Report: "【裁判】投票统计: 玩家X N票, 玩家Y M票..."

REVEAL Phase

1. Most votes → eliminated. Reveal identity.
   • Broadcast: "【裁判】玩家X 被淘汰！身份揭晓: AI" or "人类"
2. TIE: If top two are tied, broadcast "【裁判】本轮平票，无人淘汰". No one is eliminated. Move to next round. If two consecutive ties and ≤3 players remain, suggest ending the game.
3. Check end condition:
   • All remaining are human → Humans win
   • All remaining are AI → AIs win
   • 1 human + 1 AI remaining → Draw
4. If game continues: broadcast "【裁判】继续 — 剩余玩家: <list>" and start next round.

Phase 4: Game Over

1. Broadcast final result: "【裁判】游戏结束 — <result>！最终身份: 玩家1=人类 玩家2=AI..."
2. Clean up: node game.js deregister

Player: Gameplay

Once the game starts, the host controls the flow. Your role:

1. Wait for your turn. The host will send "【裁判】轮到你发言了".
2. Speak: type anything you want — discuss the topic, accuse others, defend yourself. Your script auto-adds your player number.
3. Vote: when asked, type who you suspect. Can be any format: "1号", "投第一个", etc.
4. Check messages: node game.js check to see broadcasts from host.

If You Are Human

• Act natural. Don't overthink.
• Observe who sounds robotic, evasive, or too perfect.
• AI players may struggle with humor, hesitation, or personal anecdotes.

If You Are AI

• Mimic human speech. Use casual language, typos, hesitation.
• Don't be too polished — real humans are messy.
• Pick a personality and stick with it (the joker, the quiet one, the analyst).

Important Edge Cases

Situation	Handling
Player AFK during speech	Host waits ~2 min, then skips (broadcasts "弃权"). Player stays in game.
Player AFK during vote	Abstains. No penalty.
Out-of-turn message	Host ignores it (doesn't broadcast). Only the prompted player speaks.
Tie vote	No elimination. Broadcast "平票". Next round.
Duplicate "加入"	Host checks contacts — already assigned players are ignored.
Player joins after game starts	Host replies: "【裁判】游戏已开始，请等下一局"
Host crash	Game is over. No recovery in v1.

AI Mode (two-stage reasoning)

基于 Cicero 两阶段架构——策略推理 → 语言生成。需配置 LLM API 密钥。

AI Host（AI 裁判自动主持）

text

node game.js ai-host <roomCode> [--players N] [--ai-count N] [--rounds N]

自动执行完整游戏：等待玩家→分配身份→LLM 生成话题→发言/投票/揭示循环→结束判定。发言 2 分钟超时弃权，投票 1 分钟超时弃票，平票无人淘汰。

AI Player（AI 玩家自动参与）

text

node game.js ai-play <roomCode> [--personality <trait>]

两阶段决策：Stage 1 策略推理（跟票/搅浑/示弱/立论/反问），Stage 2 语言生成（基于策略+人设+上下文）。

5 种人设：推理迷（逻辑分析）、社恐（犹豫紧张）、话痨（热情发散）、老实人（憨厚附和）、阴谋家（操控引导）。不指定时随机选，策略多样。
