-# Zusammenfassung: Task [2f388f42] - Promptdatabase integrieren
+**Task Summary: Add a Share Button `[2f488f42]`**
 
-Der Task wurde erfolgreich abgeschlossen. Das "Meeting Assistant (Transcription Tool)" verfügt nun über eine "AI Insights"-Funktion, mit der Benutzer auf Knopfdruck Meeting-Protokolle, Aufgabenlisten und rollenbasierte Zusammenfassungen aus Transkripten generieren können.
+**Status:** ✅ Done
 
-## Implementierte Features
+**Project:** Meeting Assistant (Transcription Tool)
 
-1.  **Prompt-Datenbank (`prompt_library.py`):** Eine zentrale Bibliothek für KI-Anweisungen wurde erstellt, um verschiedene Analyse-Typen (Protokoll, Action Items, Sales Summary) zu steuern.
+**Changes Implemented:**
-2.  **Insights Service (`insights_service.py`):** Eine neue Backend-Logik wurde entwickelt, die das Transkript aus der Datenbank abruft, formatiert und zusammen mit dem passenden Prompt an die Gemini 2.0 Flash API sendet.
+- A new "Share" button has been successfully added to the toolbar in the transcript detail view.
-3.  **Neuer API-Endpunkt:** Der Endpunkt `POST /api/meetings/{id}/insights` wurde implementiert, um die Analyse-Generierung anzustoßen.
+- The button is visually aligned with the existing "Copy" and "Download" actions, utilizing the `Share2` icon for consistency.
-4.  **Frontend-Integration:** Die Benutzeroberfläche wurde um ein "AI Insights"-Panel erweitert. Benutzer können über Buttons die verschiedenen Analysen anfordern. Die Ergebnisse werden in einem Modal-Fenster angezeigt und können in die Zwischenablage kopiert werden.
+- The feature is UI-only as per the requirements; clicking the button currently triggers a placeholder alert. No backend or sharing logic has been implemented yet.
-5.  **Caching:** Die generierten Ergebnisse werden in der Datenbank gespeichert. Um eine Neugenerierung zu Testzwecken zu ermöglichen, wird ein bereits vorhandenes Ergebnis gelöscht und neu erstellt, wenn die Analyse erneut angefordert wird.
 
-## Debugging-Prozess & Gelöste Probleme
+**Next Steps:**
-
+- The functionality for sharing can be implemented in a future task.
-Die Implementierung erforderte einen intensiven Debugging-Prozess, um mehrere aufeinanderfolgende Fehler zu beheben:
+- The change is ready to be committed and pushed.
-
-1.  **`ModuleNotFoundError`:** Ein anfänglicher Importfehler wurde behoben, indem eine eigenständige `gemini_client.py` für den Microservice erstellt wurde.
-2.  **Fehlender API-Schlüssel:** Der Dienst wurde so angepasst, dass er den API-Schlüssel aus einer Umgebungsvariable liest, die über `docker-compose.yml` bereitgestellt wird.
-3.  **Falsche API-Initialisierung:** Ein Programmierfehler bei der Verwendung der Gemini-Bibliothek wurde korrigiert.
-4.  **Falscher Modellname:** Der API-Aufruf wurde auf das korrekte, im Projekt etablierte `gemini-2.0-flash`-Modell umgestellt.
-5.  **Fehlerhafte Transkript-Formatierung:** Das Kernproblem, das zu leeren KI-Antworten führte, wurde durch die korrekte Interpretation der `absolute_seconds` aus der Datenbank und eine robustere Formatierungslogik gelöst.
-
-## Ergebnis
-
-Das Feature ist nun voll funktionsfähig und liefert korrekte, inhaltsbasierte Analysen. Der Code wurde bereinigt, dokumentiert und die Änderungen wurden committed.
