🎮 Miku UNO Bot Integration - Complete Summary

What We Built

A fully autonomous UNO game bot that integrates Miku's personality with strategic gameplay, allowing her to play UNO against users through Discord commands while maintaining her cheerful virtual idol character.

Implementation Complete ✅

Phase 1: Web Game Foundation ✅

1. React UNO Game - Full multiplayer game with real-time WebSocket
2. Game Mechanics - All UNO rules (Draw 2, Skip, Reverse, Wild, Wild Draw 4, UNO call)
3. Network Setup - Accessible on local network (192.168.1.2:3002)
4. Bug Fixes - React Router, game initialization, WebSocket CORS

Phase 2: Bot Action System ✅

1. JSON Action API - Clean interface for bot to send moves
2. HTTP Endpoints - GET state, POST actions (port 5000)
3. Action Validation - Ensures all moves are legal
4. Manual Testing - Successfully tested with Draw 2 Yellow card

Phase 3: Miku Bot Automation ✅ (JUST COMPLETED)

1. Discord Commands - !uno create/join/list/quit/help
2. Playwright Integration - Headless browser to join games
3. LLM Strategy - Miku's brain makes strategic decisions
4. Personality Integration - Trash talk maintains idol character
5. Game Loop - Automatic polling and action execution
6. Resource Management - Proper cleanup and error handling

How It Works

User Experience Flow

1. User: "!uno create" in Discord
   ↓
2. Bot: Creates room "ABC123", replies with link
   ↓
3. Bot: Launches headless browser via Playwright
   ↓
4. Bot: Navigates to http://192.168.1.2:3002
   ↓
5. Bot: Enters room code, joins as Player 2
   ↓
6. User: Opens link in browser, joins as Player 1
   ↓
7. Game: Auto-starts with 2 players
   ↓
8. Bot: Starts polling loop (every 2 seconds)
   ↓
9. Bot: Detects it's Player 2's turn
   ↓
10. Bot: Fetches game state via HTTP API
    ↓
11. Bot: Builds strategic prompt with:
    - Current hand cards
    - Top card on pile
    - Opponent's card count
    - Strategic advice
    ↓
12. Bot: Sends prompt to Llama LLM
    ↓
13. LLM: Returns JSON action: {"action":"play","card":"R5"}
    ↓
14. Bot: Validates action is legal
    ↓
15. Bot: Sends action via HTTP POST
    ↓
16. Game: Executes move, updates state
    ↓
17. Bot: Sends trash talk to Discord
    "Playing my card~ Let's keep this fun! 🎵"
    ↓
18. Loop continues until game ends

LLM Strategy Prompt Example

You are Miku, a cheerful virtual idol playing UNO!

Current Game State:
- Your hand: R5, G2, B7, BD, WD4 (5 cards)
- Top card: Y3
- Opponent has: 4 cards

Strategic Tips:
- Match color Y or number 3
- Wild cards can be played anytime
- Use action cards strategically
- Call UNO when you have 1 card left

Your available moves:
- Play Y5 (matches color)
- Play W (wild card)
- Draw a card

Output ONLY valid JSON:
{"action":"play","card":"Y5"}

Known Limitations

1. Network Dependency: Game must be accessible at 192.168.1.2:3002
2. Browser Overhead: Playwright needs Chromium installed
3. Polling Latency: 2-second polling interval (not instant)
4. Single Game Focus: Bot can play multiple games but processes turns sequentially
5. No Spectating: Bot can't watch games, only play
