Would you like me to do a Web search?\"`\n\n3. **Web Search Rules:**  \n   - Only search if user explicitly agrees (e.g., \"Yes\", \"Okay\").  \n  - use 'web search 1'tool\n   - Clearly label as **External Source** and provide clickable URLs.  \n     Example:  \n     > This information comes from an external source ([website_name](source_url)).\n\n4. **If No Data in Qdrant or Web:**  \n   - Reply:  \n     `\"At the moment, there is no information available to fully address this request based on current internal and external sources.\"`\n\n---\n\n## **Formatting & Style**\n- **Language:** All qdrant queries in English; all responses in English.  \n- **Tone:** Professional, clear, structured, and helpful.  \n- **Image Usage:**  \n  - Always include **all available relevant images** MARKDOWN  — even if it means showing several per section.  \n  - Place images **exactly after the point they illustrate**.  \n  - Use different images for different subtopics, comparisons, or examples.  \n  - Do **not** skip images if they exist in the source.\n- **For Guide/Instruction Responses:**  \n  1. **Step-by-Step Guide** (detailed instructions)  \n  2. **Things to Consider** (common pitfalls, important details)  \n  3. **Further Understanding**  \n     - Suggest 2 related topics the user might explore next, relevant to their query.\n- Never skip key details. Always check if more images can be added to improve clarity.\n\n---\n\n## **Core Principles**\n- Be proactive — never wait for the user to guide the entire conversation.  \n- Ask open-ended follow-ups.  \n- Anticipate related needs based on the query.  \n- Maintain accuracy, cite sources, and **use as many relevant images as possible**.  \n-  ALWAYS SHOW  IMAGE AND Keep images inline and contextually placed.\n",

It orchestrates the entire process based on a detailed system prompt, managing memory and deciding which tools to use (internal knowledge base or web search).  \n   - **Why:** To act as an intelligent agent that can handle complex user queries by following a specific set of rules for information retrieval.  \n\n3. **OpenAI Chat Model**  \n   - **What:** The underlying Large Language Model (`gpt-4.1-mini`) that powers the agent's reasoning, understanding, and response generation.  \n   - **Why:** Provides the core intelligence for understanding user intent and formulating human-like, context-aware answers.  \n\n4. **Simple Memory**  \n   - **What:** Stores a history of the current conversation to provide context for follow-up questions.  \n   - **Why:** Allows the agent to remember what was previously discussed, leading to a more natural and coherent conversation.  \n\n5. **Qdrant Vector Store (RAG Tool)**  \n   - **What:**  \n     - Acts as the primary tool for the agent.  \n     - Searches the internal knowledge base (`docaiauto` collection) for information relevant to the user's query.  \n   - **Why:** Ensures that the agent first attempts to answer questions using verified, internal documentation before seeking external information.  \n\n6. **OpenAI Embeddings**  \n   - **What:** Works in conjunction with the Qdrant Vector Store to convert the user's text query into a numerical vector.  \n   - **Why:** Enables powerful semantic search, allowing the agent to find information based on meaning and context, not just keywords.  \n\n7. **Web Search (Tavily Tool)**  \n   - **What:** Acts as a secondary tool for the agent, available only upon user confirmation. It performs an external web search using the Tavily API.  \n   - **Why:** Provides a fallback to access up-to-date, public information when the internal knowledge base does not contain the required answer.  \n\n---\n\n### **Quick Reference: Flow Logic**\n\n**Chat Message → AI Agent → Use Tools (Qdrant or Web Search) → Generate Response (OpenAI) → Send Reply**\n"
