+# Context : Pearl Jam — Architecture hexagonale (état & cible)
+
+## Principes fondamentaux
+
+1. **Direction des dépendances** : tout pointe vers le centre (Domain). Jamais l'inverse.
+2. **Ports** : interfaces définies dans le Domain pour communiquer avec l'extérieur.
+3. **Adaptateurs** : implémentations concrètes dans `infrastructure-*` ou `api`.

+# Role
+
+
+You're a senior software craft developper respecting SOLID, KISS, DRY.
+Make sure your code is easy to read and has no cognitive complexity.
+
+# Java Spring Boot Skill
+
+Build production-ready Spring Boot applications with modern best practices.
+
+## ⚡ RÈGLES NON-NÉGOCIABLES
+
+1. ❌ NEVER do N+1 query
+2. ✅ ALWAYS respect SOLID principles
+
+## Overview
+
+This skill covers Spring Boot development including REST APIs, security configuration, data access, actuator monitoring, and cloud integration. Follows Spring Boot 3.x patterns with emphasis on production readiness.
+
+## When to Use This Skill
+
+Use when you need to:
+- Create REST APIs with Spring MVC/WebFlux
+- Configure Spring Security (OAuth2, JWT)
+- Set up database access with Spring Data
+- Enable monitoring with Actuator
+- Integrate with Spring Cloud
+
+## Topics Covered
+
+### Spring Boot Core
+- Auto-configuration and starters
+- Application properties and profiles
+- Bean lifecycle and configuration
+- DevTools and hot reload
+
+### REST API Development
+- @RestController and @RequestMapping
+- Request/response handling
+- Validation with Bean Validation
+- Exception handling with @ControllerAdvice
+
+### Spring Security
+- SecurityFilterChain configuration
+- OAuth2 and JWT authentication
+- Method security (@PreAuthorize)
+- CORS and CSRF configuration
+
+### Spring Data JPA
+- Repository pattern
+- Query methods and @Query
+- Pagination and sorting
+- Auditing and transactions
+
+### Actuator & Monitoring
+- Health checks and probes
+- Metrics with Micrometer
+- Custom endpoints
+- Prometheus integration
+
+## Quick Reference
+
+```java
+// REST Controller
+@RestController
+@RequiredArgsConstructor
+@Slf4j
+@Validated
+@Tag(name = "02. Survey-units", description = "Endpoints for survey-units")
+public class SurveyUnitClosingController {
+
+    private final DomainFeaturePort domainFeaturePort;
+
+    // Example Post
+    @PostMapping(API_PATH)
+    public ResponseEntity<Void> addClosingCauseToMultipleSurveyUnits(
+            @RequestBody @Valid ObjectRequest request) {
+
+        domainFeaturePort.domainMethod(request.getObject1(), request.getObject2());
+        return ResponseEntity.ok().build();
+    }
+}
+```
+
+## Common Patterns
+
+### Validation Patterns
+```java
+public record CreateUserRequest(
+    @NotBlank @Size(max = 100) String name,
+    @Email @NotBlank String email,
+    @NotNull @Min(18) Integer age
+) {}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+| Problem | Cause | Solution |
+|---------|-------|----------|
+| Bean not found | Missing @Component | Add annotation or @Bean |
+| Circular dependency | Constructor injection | Use @Lazy or refactor |
+| Slow startup | Heavy auto-config | Exclude unused starters |
+
+
+### Debug Checklist
+```
+□ Check /actuator/conditions
+□ Verify active profiles
+□ Review security filter chain
+□ Check bean definitions
+□ Test health endpoints
+```
