+### 12. Interface Pattern
+
+**Pattern: Beschreibender Name OHNE "Interface" Suffix**
+
+#### Framework Interfaces
+
+```php
+// ✅ KORREKT - Beschreibende, behavior-fokussierte Namen
+namespace App\Framework\Cache;
+
+interface Cache
+{
+    public function get(string $key): mixed;
+    public function set(string $key, mixed $value, int $ttl = 3600): bool;
+    public function delete(string $key): bool;
+    public function clear(): bool;
+}
+
+namespace App\Framework\Logging;
+
+interface Logger
+{
+    public function emergency(string $message, array $context = []): void;
+    public function error(string $message, array $context = []): void;
+    public function info(string $message, array $context = []): void;
+}
+
+namespace App\Domain\User;
+
+interface UserRepository
+{
+    public function find(UserId $id): ?User;
+    public function save(User $user): void;
+    public function findByEmail(Email $email): ?User;
+}
+```
+
+#### Anti-Patterns
+
+```php
+// ❌ FALSCH - "Interface" Suffix ist redundant
+interface CacheInterface { }
+interface LoggerInterface { }
+interface RepositoryInterface { }
+interface UserRepositoryInterface { }
+interface EventDispatcherInterface { }
+
+// ❌ FALSCH - Generic "I" Prefix (C# Style)
+interface ICache { }
+interface ILogger { }
+interface IRepository { }
+```
+
+**Regeln:**
+- ✅ Beschreibender Name der das Verhalten/Contract beschreibt
+- ✅ Kein "Interface" Suffix
+- ✅ Kein "I" Prefix
+- ✅ Fokus auf Behavior/Capability: "Was kann es tun?"
+
+**Philosophie:**
+- Interface Namen sollten selbsterklärend sein
+- Der Typ "Interface" ist aus dem Kontext ersichtlich
+- Fokus auf Contract/Behavior, nicht auf Implementation Details
