+# noThinkProxy
+
+Anthropic API → Ollama Proxy.  
+Ermöglicht Claude-SDK-Clients (z. B. **Claude Code**) gegen einen lokalen Ollama-Server zu arbeiten, ohne Think-Modus und mit frei wählbarem Modell.
+
+## Was der Proxy tut
+
+- Empfängt Requests im **Anthropic-Format** (`POST /v1/messages`)
+- Konvertiert sie ins **Ollama-Format** (`POST /api/chat`)
+- Gibt die Antwort als **Anthropic SSE-Stream** zurück
+- Deaktiviert den Think-Modus (`think: false`)
+- Ersetzt alle `claude-*` Modellnamen durch das konfigurierte Modell
+- Konvertiert Tool-Calls und Tool-Results korrekt ins Ollama-Format
+- Dedupliziert doppelte Tool-Calls
+
+## Schnellstart (Docker)
+
+### 1. Image bauen und in Registry pushen
+
+```bash
+docker build -t registry.aquantico.lan/nothinkproxy:latest .
+docker push registry.aquantico.lan/nothinkproxy:latest
+```
+
+### 2. Auf dem Server deployen
+
+```bash
+# docker-compose.yml auf den Server kopieren
+scp docker-compose.yml server:/opt/nothinkproxy/
+
+# Auf dem Server starten
+ssh server
+cd /opt/nothinkproxy
+docker compose up -d
+```
+
+Der Proxy ist dann erreichbar unter `https://claude-proxy.aquantico.lan`.
+
+## Konfiguration (Umgebungsvariablen)
+
+| Variable      | Standard                                      | Beschreibung                        |
+|---------------|-----------------------------------------------|-------------------------------------|
+| `PORT`        | `11435`                                       | Port auf dem der Proxy lauscht      |
+| `OLLAMA_URL`  | `https://ollama.aquantico.de/api/chat`        | Vollständige Ollama Chat-API URL    |
+| `OLLAMA_MODEL`| `qwen3.6:35b-a3b-q4_K_M`                     | Modell das Ollama verwenden soll    |
+| `OLLAMA_AUTH` | *(Bearer Token)*                              | Auth-Token für den Ollama-Server    |
+
+Anpassen in `docker-compose.yml` unter `environment:`.
+
+## Claude Code installieren
+
+Auf dem Zielrechner (einmaliger Installer):
+
+```bash
+curl -fsSL https://claude-proxy.aquantico.lan/install.sh | bash
+```
+
+Der Installer prüft Node.js, installiert es bei Bedarf und installiert Claude Code via npm.
+
+## Claude Code mit dem Proxy starten
+
+```bash
+ANTHROPIC_BASE_URL=https://claude-proxy.aquantico.lan claude
+```
+
+Als dauerhafter Alias in `~/.bashrc` oder `~/.zshrc`:
+
+```bash
+alias claude-local='ANTHROPIC_BASE_URL=https://claude-proxy.aquantico.lan claude'
+```
+
+## Lokaler Betrieb (ohne Docker)
+
+```bash
+npm install
+node app.js
+```
+
+Mit anderem Modell / Server:
+
+```bash
+OLLAMA_URL=http://localhost:11434/api/chat \
+OLLAMA_MODEL=llama3.2 \
+OLLAMA_AUTH=mytoken \
+node app.js
+```
+
+Dann Claude Code starten:
+
+```bash
+ANTHROPIC_BASE_URL=http://localhost:11435 claude
+```
+
+## Info-Seite

+Beim Aufruf von `https://claude-proxy.aquantico.lan/` (ohne Pfad) erscheint eine HTML-Seite mit der aktuellen Konfiguration und Installations-Anweisungen.
