+# Example Project PRD
+
+Ein einfaches Beispiel-Projekt, um Ralphy zu demonstrieren.
+
+## Kontext
+
+Wir bauen eine kleine CLI-Anwendung, die Markdown-Dateien in HTML konvertiert.
+
+## Tasks
+
+- [ ] Projekt-Setup: package.json erstellen mit TypeScript und Vitest
+- [ ] Funktion schreiben, die Markdown-Headings (#, ##, ###) in HTML-Tags konvertiert
+- [ ] Funktion schreiben, die **bold** und *italic* Text konvertiert
+- [ ] Funktion schreiben, die Listen (- item) in HTML-Listen konvertiert
+- [ ] CLI-Entry-Point erstellen, der eine Datei einliest und konvertiert
+- [ ] README.md mit Nutzungsanleitung schreiben
+
+## Akzeptanzkriterien
+
+- Alle Tests gruen
+- TypeScript kompiliert ohne Fehler
+- CLI kann mit `npx ts-node src/index.ts input.md` ausgefuehrt werden
+
+## Notizen
+
+- Keine externen Markdown-Libraries verwenden (Lernzweck)
+- Einfache Regex-basierte Konvertierung reicht aus

 ## Changelog
 
 ### v4.7.2
+- **Single-task repeat mode**: added `--repeat <n>` with `--continue-on-failure` and fail-fast defaults; fatal errors still abort immediately
 - **Improved auth error detection**: simplified `extractAuthenticationError` function with better edge case handling (e.g., JSON dumps during login)
 - **Added project standards**: `CLAUDE.md`, `.cursorrules`, `CONTRIBUTING.md` for consistent AI-assisted development
 - **Enhanced default prompts**: enforce concise, focused code changes
