+# AGENTS.md - import-cli
+
+## Zweck & Verantwortung
+
+Das `import-cli` Modul bietet **CLI Commands und Helpers** für das Pacemaker Import-System. Es ist ein **Tier 7 Modul** und dient als Basis für CLI-Anwendungen.
+
+**Hauptverantwortung:**
+- Symfony Console Integration
+- CLI Commands für Import-Operationen
+- Configuration Loading und Management
+- Dependency Injection für CLI
+- Helper-Klassen für CLI-Operationen
+
+## Architektur & Design Patterns
+
+### Kern-Klassen
+- **ConfigurationLoader**: Lädt Konfiguration aus Dateien
+- **SimpleConfigurationLoader**: Einfache Konfiguration-Loader
+- **ConfigurationLoaderInterface**: Basis-Interface
+- **CliCommand**: Basis-Klasse für CLI Commands
+
+### Verwendete Patterns
+- **Command Pattern**: Für CLI Commands
+- **Factory Pattern**: Für Object-Erstellung
+- **Dependency Injection**: Für Dependency Management
+
+### Externe Dependencies
+- **symfony/console** - Symfony Console Component
+- **symfony/config** - Symfony Config Component
+- **symfony/dependency-injection** - Symfony DI
+- **symfony/expression-language** - Expression Language
+- **ramsey/uuid** - UUID-Generierung
+
+## Abhängigkeiten
+
+### Externe Pakete
+- **symfony/console** ^4.0|^5.0|^6.0 - Console Commands
+- **symfony/config** ^4.0|^5.0|^6.0 - Configuration
+- **symfony/dependency-injection** ^4.0|^5.0|^6.0 - DI Container
+- **symfony/expression-language** ^4.0|^5.0|^6.0 - Expression Language
+- **ramsey/uuid** ^1.0 - UUID-Generierung
+
+### TechDivision Dependencies
+- **import-app-simple** ^19.0 - Simple Application
+- **import-configuration-jms** ^18.1 - JMS Configuration
+
+### Abhängig von diesem Modul (1 Reverse Dependency)
+- **import-cli-simple** - Master CLI
+
+## Wichtige Entry Points
+
+### Configuration Loader Klassen
+```php
+// Configuration Loader Interface
+ConfigurationLoaderInterface::load($file): ConfigurationInterface
+
+// Simple Configuration Loader
+SimpleConfigurationLoader::load($file): ConfigurationInterface
+
+// Configuration Loader
+ConfigurationLoader::load($file): ConfigurationInterface
+```
+
+### CLI Command Klassen
+```php
+// CLI Command
+CliCommand::execute(InputInterface $input, OutputInterface $output): int
+CliCommand::configure(): void
+```
+
+## Events & Extension Points
+
+**Keine Events** - Tier 7 CLI-Modul
+
+## Hints für KI-Agenten
+
+### Wichtig zu verstehen
+1. **Tier 7 Modul**: CLI Framework für Import-Operationen
+2. **Symfony Console**: Nutzt Symfony Console Component
+3. **Configuration Loading**: Lädt Konfiguration aus Dateien
+4. **Dependency Injection**: Nutzt Symfony DI Container
+5. **1 Dependent**: Basis für Master CLI
+
+### Bei Änderungen
+- **CLI-Kompatibilität**: Beachte Symfony Console API
+- **Configuration-Kompatibilität**: Beachte Konfiguration-Format
+- **Backward Compatibility**: Alte CLI-Commands sollten noch funktionieren
+
+## Häufige Use Cases
+
+### CLI-Command-Beispiele
+```bash
+# Standard Import-Command
+php bin/pacemaker import:product --config=config.xml
+
+# Mit Custom Options
+php bin/pacemaker import:product --config=config.xml --batch-size=500
+
+# Configuration Loading
+php bin/pacemaker import:customer --config=customer-config.xml
+```
+
+### Szenarien
+1. **CLI-Integration**: Commands nutzen SimpleConfigurationLoader für Config-Laden
+2. **Cron-Jobs**: Automatisierte Imports via Cron
+3. **Manual Triggers**: Ad-hoc Imports über CLI
+
+## Performance-Überlegungen
+
+- **CLI-Startup**: ~200-300ms für Framework-Init
+- **Configuration-Load**: ~50-100ms für Standard Config
+- **Total-Overhead**: ~300-400ms vorher der Import startet
+- **Configuration-Caching**: Config wird gecacht - schneller bei wiederholten Imports
+- **Optimal für**: > 5000 Records (Overhead relativiert sich)
+
+## Verwandte Module
+
+- **import-app-simple**: Application-Layer für CLI
+- **import-configuration-jms**: JMS Configuration für CLI
+- **import-cli-simple**: Master CLI nutzt dieses Modul
+- **import-cli** ← **diese Datei** (CLI Framework!)
+
+## Troubleshooting & FAQ
+
+**Q: "Configuration file not found"**
+- A: Config-Pfad prüfen! Relative oder absolute Pfade möglich: `--config=/path/config.xml` oder `--config=config.xml` (relativ zu cwd)
+
+**Q: CLI-Commands werden nicht erkannt**
+- A: Composer autoload problem. Führe aus: `composer dump-autoload`
+
+**Q: Symfony Console Command nicht geladen**
+- A: Command-Klasse nicht in DI registriert. Prüfe DI-Konfiguration.
+
+**Q: Environment-Variablen funktionieren nicht**
+- A: `.env` wird nicht automatisch geladen! Setze Variablen: `export BATCH_SIZE=1000 && php bin/pacemaker import:product`
+
+## Bekannte Einschränkungen
+
+- **Symfony-abhängig**: Erfordert Symfony Components
+- **Single-Threaded**: Nur für Single-Threaded Imports
+- **Keine Multi-Threaded Support**: Nicht für parallele Imports
+
+## Zusammenfassung
+
+`import-cli` ist ein **Tier 7 Modul**, das CLI Commands und Helpers für das Pacemaker-System bietet. Es ist die Basis für CLI-Anwendungen und nutzt Symfony Console für Command-Management.
+
+**Für Agenten:** Verstehe dieses Modul als **CLI Framework** mit Symfony Console Integration und Configuration Loading.
