# Project Analysis: AI Agents from Scratch (Lenzcom Email/Chat) ## Overview This project is a Node.js-based AI Chat Application hosted on Hugging Face Spaces. It serves a single-page web interface where users can interact with an AI model (dahanhstd-1.0) powered by ode-llama-cpp. The application is designed to be self-contained, with the HTML frontend embedded directly in the server code. ## Directory Structure - **Root**: H:\BuilddingProject\ai-agents-from-scratch - **Source Code**: - server.js: The main entry point. Handles HTTP requests, serves the embedded HTML, and manages the LLM inference. - src/index.js (implied): Contains the AI logic wrapper classes (SystemMessage, HumanMessage, etc.). - **Configuration**: - MssterPrompt_Talk2People.txt (to be renamed): Contains the system prompt for the 'talk2people' role. - secrets.local.md: Stores local secrets (not to be pushed). - **Deployment**: - hf_deploy.py: Python script for deploying to Hugging Face Spaces. ## Key Components 1. **Server (server.js)**: - Uses express for the web server. - Dynamically imports AI modules from ./src/index.js. - Loads the LLM model from ./models/Qwen3-1.7B-Q8_0.gguf. - Defines prompts for different roles ('talk2people', 'coder', 'default'). - Embeds the frontend HTML/CSS/JS in the HTML_PAGE constant. 2. **Frontend (Embedded in server.js)**: - Simple HTML/CSS/JS interface. - Communicates with the backend via /chat (POST) and /info (GET) endpoints. - Handles chat history and role switching. ## Logic Flow 1. **Initialization**: Server starts, loads the LLM model (initModel()). 2. **User Request**: User sends a message via the web UI. 3. **Processing**: - Frontend sends JSON to /chat. - Backend constructs a message chain (System + History + User Message). - LLM generates a response. 4. **Response**: Backend returns JSON { reply, model, ... } to the frontend. ## Current Issues & TODOs - **File Naming**: MssterPrompt_Talk2People.txt has a typo. - **Role/Prompt Mismatch**: The text in the prompt file does not match the 'Talk2People' persona. - **UI Feedback**: 'Thinking' state is just '...', needs to be more descriptive. - **Greeting**: Initial greeting is hardcoded and outdated.
