# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
This is a single-file chatbot application for Romfast technical support. The project consists of a standalone HTML file (`chatbot_maria.html`) that implements a full-featured chatbot interface using the Flowise embed library.
## Architecture
The chatbot integrates with a Flowise API backend hosted at `https://mutual-special-koala.ngrok-free.app` using chatflow ID `d4911620-07fe-41f8-adb4-f2f52d6ec766`.
Key architectural components:
- **Flowise Integration**: Uses the Flowise embed library from CDN for the main chatbot functionality
- **Direct API Mode**: Supports URL parameter-based message handling that bypasses the chat interface and displays responses in a modal overlay
- **Dual Display Modes**:
- Standard chatbot widget with starter prompts
- Direct API response modal when `?message=` URL parameter is present
## Key Features
- **Maria ChatBot**: Romanian language technical support assistant for Romfast ROA system
- **URL Parameter Support**: Can accept initial messages via `?message=` URL parameter
- **Conditional UI**: Hides starter prompts when a direct message is provided
- **Chat History**: Saves conversation history to localStorage when transitioning from API mode to chat mode
- **Responsive Design**: Mobile-friendly layout with collapsible menu
## Configuration
The chatbot configuration is embedded in the JavaScript module:
- API Host: `https://mutual-special-koala.ngrok-free.app`
- Chatflow ID: `d4911620-07fe-41f8-adb4-f2f52d6ec766`
- Romanian language interface with predefined starter prompts about eFactura, SAFT declarations, and auto service workflows
## Development Notes
This is a static HTML file with no build process. To modify:
1. Edit `chatbot_maria.html` directly
2. Test by opening in a browser
3. For URL parameter testing, use format: `chatbot_maria.html?message=your%20message%20here`
The application handles two distinct user flows based on URL parameters, switching between embedded chatbot widget and full-screen API response modal.

# Chatbot Maria - Romfast Support
Un chatbot de suport tehnic pentru sistemul ROA, construit cu Flowise embed.
## Funcționalități
- **Chatbot integrat**: Interface de chat folosind Flowise embed library
- **Suport pentru URL parametri**: Permite trimiterea directă a mesajelor prin URL
- **Două moduri de afișare**:
- Chat widget standard cu prompt-uri predefinite
- Modal de răspuns direct pentru mesaje din URL
- **Gestionare robustă a caracterelor speciale**: Suport pentru URL-uri cu secvențe de encoding problematice
## Testare
### 1. Test de bază
Deschide fișierul direct în browser:
```
chatbot_maria.html
```
### 2. Test cu mesaj din URL
Testează funcția de mesaj direct prin URL:
```
chatbot_maria.html?message=Cum%20se%20actualizeaza%20tokenul%20eFactura?
```
### 3. Test cu caractere speciale
Testează cu mesaje care conțin caractere speciale (cazul problematic):
```
chatbot_maria.html?message=F:%20Header%20(1)%20sectiune%20Company%20(1)%20sectiune%20BankAccount%20(1)%20eroare%20structura:%20grupul%20%27%BankAccount_choice0%27%20ar%20fi%20trebuit%20sa%20apara%20de%20minimum%201%20ori,%20dar%20apare%20efectiv%20de%200%20ori
```
### 4. Debugging în Browser
Pentru a vedea ce se întâmplă în timpul testării:
1. **Deschide Developer Tools**: F12 în browser
2. **Mergi la tab-ul Console**
3. **Încarcă pagina cu parametrul URL**
4. **Monitorizează log-urile**:
- `"Parametru decodat cu URLSearchParams:"` - prima încercare
- `"Valoare brută din URL (fallback):"` - dacă URLSearchParams nu funcționează
- `"Parametru decodat cu metoda sigură:"` - rezultatul final
- `"Se trimite mesajul direct prin API:"` - confirmă că mesajul e trimis
- `"Status răspuns:"` - codul de răspuns al API-ului
- `"Răspuns primit de la API:"` - răspunsul de la chatbot
### 5. Verificare Funcționalitate
**Testul a reușit dacă**:
- ✅ Nu vezi erori "URI malformed" în console
- ✅ Vezi mesajul decodat în console
- ✅ Vezi "Se trimite mesajul direct prin API"
- ✅ Vezi răspunsul API în modal
**Semnale de probleme**:
- ❌ "Eroare la decodarea parametrului URL"
- ❌ "URI malformed"
- ❌ Pagina nu afișează nimic
- ❌ Request-ul API eșuează cu timeout
### 6. Testare Offline
Poți testa funcțiile de decodificare fără server:
1. **Deschide Developer Tools** (F12)
2. **Mergi la tab-ul Console**
3. **Testează manual funcțiile**:
```javascript
// Test URLSearchParams
const urlParams = new URLSearchParams("?message=test%20cu%20caractere%20speciale");
console.log(urlParams.get('message'));
// Test cu URL problematic
const problematicUrl = "?message=F:%20Header%20(1)%20sectiune%20Company%20(1)%20sectiune%20BankAccount%20(1)%20eroare%20structura:%20grupul%20%27%BankAccount_choice0%27%20ar%20fi%20trebuit%20sa%20apara%20de%20minimum%201%20ori,%20dar%20apare%20efectiv%20de%200%20ori";
const testParams = new URLSearchParams(problematicUrl);
console.log(testParams.get('message'));
```
## Configurare API
Chatbot-ul se conectează la:
- **API Host**: `https://mutual-special-koala.ngrok-free.app`
- **Chatflow ID**: `d4911620-07fe-41f8-adb4-f2f52d6ec766`
Pentru modificare, editează valorile în secțiunea JavaScript:
```javascript
const apiHost = "https://mutual-special-koala.ngrok-free.app";
const chatflowId = "d4911620-07fe-41f8-adb4-f2f52d6ec766";
```
## Troubleshooting
### Problema: "URI malformed"
**Soluție**: Implementarea actuală gestionează automat această problemă prin decodificare sigură chunk-by-chunk.
### Problema: API nu răspunde
**Verificări**:
1. API host-ul este accesibil
2. Chatflow ID-ul este corect
3. Conexiunea la internet funcționează
4. Nu sunt blocate request-urile CORS
### Problema: Pagina nu se încarcă
**Verificări**:
1. Fișierul HTML este valid
2. CDN-ul Flowise este accesibil: `https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js`
3. Nu sunt erori JavaScript în console
### Problema: Mesajul nu se trimite
**Verificări**:
1. Parametrul URL este corect
2. Mesajul nu este gol după decodificare
3. API-ul acceptă request-ul
4. Nu sunt erori de timeout (30 secunde)
## Prompt-uri Predefinite
Chatbot-ul afișează următoarele prompt-uri standard când nu este specificat un mesaj în URL:
- Cum se actualizeaza tokenul eFactura?
- Cand se completeaza codul de plata pentru declaratia SAFT?
- Care sunt pasii pentru emiterea unei facturi service auto?
- Cum se valideaza o comanda service auto?
- Cum se deschide o comanda service auto?
- Cum se modifica datele initiale ale unei comenzi service auto?

<h3>How it works:</h3>

<li>First tries URLSearchParams (works for most cases)</li>
<li>If URLSearchParams fails, uses safe chunk-by-chunk processing</li>
<li>Only attempts to decode valid hex sequences (%XX format)</li>
<li>Preserves invalid sequences like %B instead of corrupting them</li>
<li>Handles incomplete sequences gracefully</li>

<h3>Key Differences:</h3>
<ul>
<li><strong>Current:</strong> Uses URLSearchParams first, falls back to aggressive manual replacement that corrupts %B</li>
<li><strong>Improved:</strong> Uses URLSearchParams first, falls back to safe chunk-by-chunk processing that preserves invalid sequences</li>
<li><strong>Issue:</strong> The %B in the URL is not valid URL encoding (should be %0B or %42)</li>
<li><strong>Solution:</strong> The improved version handles invalid sequences gracefully</li>
</ul>
<h3>Expected Message Content:</h3>
<div class="code">F: Header (1) sectiune Company (1) sectiune BankAccount (1) eroare structura: grupul '%BankAccount_choice0' ar fi trebuit sa apara de minimum 1 ori, dar apare efectiv de 0 ori</div>
