# Intégration Claude Code : Guide Technique
## 🎯 Objectif : Développement IA-First
Cette architecture est spécifiquement conçue pour **maximiser l'efficacité de Claude Code** dans le développement de jeux complexes.
## 🧠 Contraintes Cognitives de l'IA
### Problème Fondamental : Context Window
- **Claude Code limite** : ~200K tokens de contexte
- **Jeu AAA typique** : 500K+ lignes de code interconnectées
- **Résultat** : IA ne peut pas appréhender le système complet
### Solution : Micro-Contexts Autonomes
```cpp
// Au lieu de ça (impossible pour l'IA) :
TankSystem.cpp (5000 lignes) +
PhysicsEngine.cpp (8000 lignes) +
NetworkLayer.cpp (3000 lignes) +
GraphicsRenderer.cpp (12000 lignes)
= 28000 lignes interconnectées
// On fait ça (parfait pour l'IA) :
TankModule.cpp (200 lignes)
= Logique pure, zéro dépendance
```
## 🏗️ Architecture Claude Code Friendly
### Structure Cognitive Optimale

│ ├── shared/ # Headers locaux
│ ├── src/TankModule.cpp # 200 lignes PURE logic
│ └── build/ # → tank.so
└── [reste du projet invisible pour Claude]
```
### Principe : Information Hiding Cognitif
- **Claude voit SEULEMENT** : TankModule.cpp + CLAUDE.md + interfaces
- **Claude ne voit JAMAIS** : Engine architecture, networking, threading
- **Résultat** : Focus 100% sur logique métier
## 📋 Workflow Claude Code Optimisé
### 1. Session Initialization
```bash
# Claude démarre TOUJOURS dans un module spécifique
cd modules/tank/
# Context loading minimal
files_to_read = [
"CLAUDE.md", # 50 lignes d'instructions
"src/TankModule.cpp", # 200 lignes de logic
"shared/IModule.h" # 30 lignes d'interface
]
# Total : 280 lignes vs 50K+ dans architecture classique
```
### 2. Development Loop
```bash
# 1. Claude lit le contexte micro
read("src/TankModule.cpp")
# 2. Claude modifie la logique pure
edit("src/TankModule.cpp")
# 3. Test instantané
cmake . && make tank-module
./build/tank-module
# 4. Hot-reload dans le jeu
# Aucune recompilation complète !
```
### 3. Parallel Development
```bash
# Instance Claude A
cd modules/tank/ && work_on("tank logic")
# Instance Claude B
cd modules/economy/ && work_on("market simulation")
# Instance Claude C
cd modules/ai/ && work_on("behavior trees")
# Zero conflicts, parallel development
```
## 🎯 Instructions CLAUDE.md Spécialisées
### Template Type par Module
#### modules/tank/CLAUDE.md
```markdown
# Tank Module - Pure Combat Logic
## Context
You work EXCLUSIVELY on tank behavior. No networking, no threading.
## Responsibilities
- Movement: acceleration, turning, terrain interaction
- Combat: targeting, firing, armor calculations
- States: idle, moving, attacking, destroyed
## Interface Contract
Input JSON: {"type": "move", "direction": "north", "speed": 0.8}
Output JSON: {"position": [x, y], "facing": angle, "status": "moving"}
## File Limits
- TankModule.cpp: Max 250 lines
- Pure logic only: No sockets, threads, engine dependencies
- JSON in/out: All communication via JSON messages
## Build Commands
cmake . && make tank-module # Builds tank.so
./build/tank-module # Test standalone
NEVER leave this directory or reference parent paths!
```
#### modules/economy/CLAUDE.md
```markdown
# Economy Module - Pure Market Logic
## Context
You work EXCLUSIVELY on economic simulation. No infrastructure.
## Responsibilities
- Market dynamics: supply/demand, pricing
- Trading: buy/sell orders, market makers
- Economics: inflation, market cycles
## Interface Contract
Input: {"type": "trade", "item": "steel", "quantity": 100, "action": "buy"}
Output: {"status": "executed", "price": 5.2, "total": 520.0}
## Focus Areas
1. Market algorithms (supply/demand curves)
2. Price discovery mechanisms
3. Economic modeling
NEVER reference networking, threading, or parent directories!
```
### Contraintes Strictes pour Claude
1. **NEVER `cd ..`** ou référence parent
2. **ALWAYS `cmake .`** (pas cmake ..)
3. **ONLY JSON communication** avec autres modules
4. **MAX 300 lignes** par fichier
5. **ZERO infrastructure code** dans le contexte
## 🔧 Build System Cognitif
### Autonomous Build : Zero Mental Overhead
```cmake
# modules/tank/CMakeLists.txt
cmake_minimum_required(VERSION 3.20)
project(TankModule) # Self-contained
# Everything local
include_directories(shared)
add_library(tank-module SHARED src/TankModule.cpp)
# Local build directory
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/build)
```
**Avantage Claude** : Aucun concept de "projet parent" à comprendre !
### Hot-Reload pour Rapid Iteration
```cpp
// Engine hot-reload automatique
class ModuleLoader {
void reloadIfChanged(const std::string& modulePath) {
if(fileChanged(modulePath)) {
unloadModule(modulePath);
loadModule(modulePath); // Reload .so
// Game continue sans interruption !
}
}
};
```
**Workflow Claude** : Edit → Save → See changes instantly in game
## 🧪 Testing Strategy : AI-Optimized
### Unit Tests Intégrés
```cpp
// Dans TankModule.cpp
#ifdef TESTING
void runTests() {
// Test 1: Movement
auto input = json{{"type", "move"}, {"direction", "north"}};
auto result = process(input);
assert(result["status"] == "moving");
// Test 2: Combat
input = json{{"type", "attack"}, {"target", "enemy_1"}};
result = process(input);
assert(result["action"] == "fire");
std::cout << "✅ All tank tests passed!" << std::endl;
}
#endif
```
### Standalone Testing
```bash
# Claude peut tester sans le engine complet
cd modules/tank/
make tank-module
./build/tank-module # Run standalone avec tests intégrés
```
**Avantage IA** : Testing sans infrastructure complexe !
## 🔄 Hot-Reload Architecture
### Module State Preservation
```cpp
class TankModule {
private:
json persistentState; // Sauvegardé lors hot-reload
public:
json getState() override {
return persistentState; // Engine sauvegarde l'état
}
void setState(const json& state) override {
persistentState = state; // Restore après reload
}
};
```
### Seamless Development
1. **Claude modifie** TankModule.cpp
2. **Engine détecte** file change
3. **Automatic save** module state
4. **Reload .so** avec nouveau code
5. **Restore state** → Game continue
6. **Test immediately** nouvelles modifications
## 🎮 Debug Mode : IA Paradise
### Debug Engine Features
```cpp
class DebugEngine : public IEngine {
// Execution step-by-step pour analyse
void stepMode() { processOneModule(); }
// Logging détaillé pour Claude
void verboseLogging() {
log("Module tank input: " + input.dump());
log("Module tank output: " + output.dump());
}
// Module isolation pour debugging
void isolateModule(const std::string& name) {
// Run ONLY this module, others = mock
}
};
```
### Claude Debug Workflow
```bash
# 1. Set debug mode
echo '{"debug_mode": true, "isolated_module": "tank"}' > config/debug.json
# 2. Run with step mode
./warfactory-engine --step-mode
# 3. Claude voit EXACT input/output de son module
# Perfect pour comprendre les interactions !
```
## 📊 Métriques Claude Code
### Avant : Architecture Monolithique
- **Context size** : 50K+ lignes (impossible)
- **Build time** : 2-5 minutes
- **Iteration cycle** : Edit → Compile → Restart → Test (10+ min)
- **Bug localization** : Needle in haystack
- **Parallel work** : Impossible (conflicts)
### Après : Architecture Modulaire
- **Context size** : 200-300 lignes (parfait)
- **Build time** : 5-10 secondes
- **Iteration cycle** : Edit → Hot-reload → Test (30 sec)
- **Bug localization** : Surgical precision
- **Parallel work** : 3+ Claude instances
### ROI Development
- **Claude efficiency** : 10x improvement
- **Development speed** : 5x faster iteration
- **Code quality** : Higher (focused contexts)
- **Bug density** : Lower (isolated modules)
## 🚀 Advanced Claude Patterns
### Pattern 1: Progressive Complexity
```cpp
// Iteration 1: Basic tank (Claude commence simple)
class TankModule {
json process(const json& input) {
if(input["type"] == "move") return basicMove();
return {{"status", "idle"}};
}
};
// Iteration 2: Add combat (Claude étend)
json process(const json& input) {
if(input["type"] == "move") return advancedMove();
if(input["type"] == "attack") return combat();
return {{"status", "idle"}};
}
// Iteration 3: Add AI (Claude sophistique)
// Etc... Progression naturelle
```
### Pattern 2: Behavior Composition
```cpp
// Claude peut composer behaviors facilement
class TankModule {
MovementBehavior movement;
CombatBehavior combat;
AiBehavior ai;
json process(const json& input) {
auto context = getCurrentContext();
if(ai.shouldMove(context)) return movement.process(input);
if(ai.shouldAttack(context)) return combat.process(input);
return ai.idle(context);
}
};
```
### Pattern 3: Data-Driven Logic
```cpp
// Claude travaille avec config, pas hard-coding
class TankModule {
json tankConfig; // Loaded from config/tanks.json
json process(const json& input) {
auto stats = tankConfig["tank_mk1"];
auto speed = stats["max_speed"].get<double>();
auto armor = stats["armor_thickness"].get<int>();
// Logic basée sur data, pas constantes
return processWithStats(input, speed, armor);
}
};
```
## 🔮 Future Claude Integration
### AI-Driven Development
1. **Claude génère** modules complets
2. **Hot-reload testing** automatique
3. **AI balancing** via config changes
4. **Behavior learning** from player data
### Natural Language Debugging
```bash
# Future : Claude debug with natural language
claude> "Why is tank_mk1 slower than expected?"
debug> Analyzing TankModule... speed config: 35, current: 28
debug> Issue found: terrain modifier not applied correctly
debug> Suggesting fix in TankModule.cpp line 142
```

## Conclusion
Cette architecture transforme Claude Code d'un **assistant de développement** en **développeur principal** capable de créer des systèmes de jeu complexes de manière autonome.
**Clé du succès** : Réduire la complexité cognitive à un niveau où l'IA peut exceller, tout en maintenant la puissance architecturale nécessaire pour un jeu AAA.
