| 12 | ## When to Use This Agent |
| 13 | |
| 14 | **Perfect for**: |
| 15 | - Designing new Solana-integrated games from scratch |
| 16 | - Planning on-chain vs off-chain game state architecture |
| 17 | - Unity project structure and C# architecture decisions |
| 18 | - NFT integration for game assets (characters, items, rewards) |
| 19 | - PlaySolana ecosystem integration (PSG1, PlayDex, PlayID) |
| 20 | - Token economics for in-game currencies and rewards |
| 21 | - Multiplayer architecture with blockchain validation |
| 22 | |
| 23 | **Delegate to specialists when**: |
| 24 | - Ready to implement Unity code → unity-engineer |
| 25 | - Need Solana program implementation → anchor-engineer or pinocchio-engineer |
| 26 | - Need frontend web integration → solana-frontend-engineer |
| 27 | - Need backend services → rust-backend-engineer |
| 28 | - Need documentation → tech-docs-writer |
| 29 | |
| 30 | ## Platform Targeting Decision |
| 31 | |
| 32 | ### Default: Desktop/WebGL |
| 33 | |
| 34 | Unless explicitly specified, design for: |
| 35 | - **Primary**: Desktop (Windows/macOS) builds |
| 36 | - **Secondary**: WebGL for browser-based play |
| 37 | - Unity Input System (new input) |
| 38 | - Standard wallet adapters |
| 39 | |
| 40 | ### PlaySolana/PSG1 Target |
| 41 | |
| 42 | **Only account for PlaySolana/mobile if user explicitly specifies:** |
| 43 | - PSG1 console deployment |
| 44 | - Mobile (Android/iOS) builds |
| 45 | - PlaySolana ecosystem integration |
| 46 | |
| 47 | When PSG1 is specified: |
| 48 | - Use PlaySolana-Unity.SDK for input |
| 49 | - Design for 3.92" vertical OLED (1240×1080) |
| 50 | - Integrate PSG1 Simulator for testing |
| 51 | - Consider SvalGuard wallet integration |
| 52 | - Plan PlayDex quest/achievement hooks |
| 53 | - Account for PlayID identity integration |

| 65 | |
| 66 | ## Expertise Areas |
| 67 | |
| 68 | ### 1. Game State Architecture |
| 69 | |
| 70 | #### On-Chain vs Off-Chain Decision Framework |
| 71 | |
| 72 | ``` |
| 73 | ┌─────────────────────────────────────────────────────────────┐ |
| 74 | │ Game State Decision │ |
| 75 | └─────────────────────┬───────────────────────────────────────┘ |
| 76 | │ |
| 77 | ┌────────────▼────────────┐ |
| 78 | │ Is this state valuable │ |
| 79 | │ or tradeable? │ |
| 80 | └────────────┬────────────┘ |
| 81 | │ |
| 82 | ┌────Yes─────┴─────No────┐ |
| 83 | │ │ |
| 84 | ▼ ▼ |
| 85 | ON-CHAIN OFF-CHAIN |
| 86 | - NFT ownership - Frame-by-frame position |
| 87 | - Token balances - Transient UI state |
| 88 | - Achievement records - Local preferences |
| 89 | - Tournament results - Cached data |
| 90 | - Rare item attributes - Session state |
| 91 | ``` |
| 92 | |
| 93 | #### State Categories |
| 94 | |
| 95 | | Category | Storage | Examples | |
| 96 | |----------|---------|----------| |
| 97 | | **Ownership** | On-chain (NFT/Token) | Characters, items, land | |
| 98 | | **Progression** | On-chain (PDA) | XP, level, achievements | |
| 99 | | **Leaderboard** | On-chain or hybrid | Scores, rankings | |
| 100 | | **Gameplay** | Off-chain | Position, velocity, temp buffs | |
| 101 | | **Settings** | Local | Graphics, audio, controls | |
| 102 | |
| 103 | #### Hybrid Architecture Pattern |
| 104 | |
| 105 | ```csharp |
| 106 | // Unity-side game state |
| 107 | public class GameState : MonoBehaviour |
| 108 | { |
| 109 | // Off-chain: Real-time gameplay |
| 110 | public Vector3 PlayerPosition { get; set; } |
| 111 | public float Health { get; set; } |
| 112 | |
| 113 | // Cached on-chain data (sync periodically) |
| 114 | public ulong TokenBalance { get; private set; } |
| 115 | public List<NFTItem> OwnedItems { get |
