| # 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| - **Greeting**: Initial greeting is hardcoded and outdated. | |
