-# R Vibe Tool
+# Henry IRC Server
 
-## Overview
-
-R Vibe Tool is a powerful Command-Line Interface (CLI) utility designed for Linux environments, offering advanced AI-assisted development capabilities with elegant markdown output.
+A simple IRC server implemented in Python as a package named `henry`.
 
 ## Features
+- Basic IRC commands: NICK, USER, JOIN, PRIVMSG, QUIT
+- Supports multiple clients and channels
 
-- **Flexible AI Integration**: Support for multiple AI models including:
-  - OpenAI GPT-3.5-turbo (default, if you did not set API key)
-  - Ollama
-  - Anthropic Claude
-  - Grok
+## Installation
 
-- **Customizable Behavior**: Configure tool behavior through `~/.rcontext.txt`
-- **Agent Support**: Intelligent context-aware assistance
-- **Markdown Output**: Clean, readable documentation generation
+Clone the repository or copy the `henry` package directory.
 
-## Prerequisites
+## Usage
 
-- Linux operating system
-- Configured AI model access
+Run the IRC server using the CLI entry point:
 
-## Configuration
-
-### Environment Variables
-
-TIP: create bash files containg these variables and make them easily accessable. For example by symlinking them to `~/.bash_aliases` or `~/.bash_profile`. Or even easier, make them executable and put them in /usr/local/bin.
-
-#### Ollama Configuration
 ```bash
-export R_MODEL="qwen2.5:3b"
-export R_BASE_URL="https://ollama.molodetz.nl"
-./r
+python -m henry.cli
 ```
 
-#### Claude Configuration
+The server listens on `127.0.0.1:6667` by default.
+
+## Connecting
+
+Use any IRC client to connect to `localhost` on port `6667`.
+
+## Example
+
 ```bash
-export R_MODEL="claude-3-5-haiku-20241022"
-export R_BASE_URL="https://api.anthropic.com"
-export R_KEY="sk-ant-[your-key]"
-./r
+# Using irssi client
+irssi -c 127.0.0.1 -p 6667
 ```
 
-#### OpenAI Configuration
-```bash
-export R_MODEL="gpt-4o-mini"
-export R_BASE_URL="https://api.openai.com"
-export R_KEY="sk-[your-key]"
-./r 
-```
-
-#### Grok Configuration
-```bash
-export R_MODEL="grok-2"
-export R_BASE_URL="https://api.x.ai"
-export R_USE_STRICT=false
-export R_KEY="xai-gfh"
-./r
-```
-
-## Best Practices
-
-1. Use `~/.rcontext.txt` to define specific behavioral instructions
-2. Include file saving steps in your context instructions
-3. Use the `index` tool to initialize only source files, excluding environment and node_modules
-
-## Example Project
-
-For a comprehensive example of R Vibe Tool in action, visit: 
-[Streamii Project](https://molodetz.nl/projects/streamii/README.md.html)
-
-## Limitations
-
-- OpenAI key usage is temporary and limited
-- Performance may vary depending on the selected AI model
-
-## Support
-
-For issues or contributions, please refer to the project repository.

-## AI Chat Prompt and API Integration with JSON-C
+# Application Review Report
 
-This project offers functionalities for creating and managing AI chat interactions. It utilizes the JSON-C library to handle JSON objects, providing easy integration with HTTP networking and message handling.
+## Entry Point
+- The application's entry point is defined in `main.c`.
+- Currently, it prints "Hello, World!".
 
-### Features
-- **Chat Prompt Management**: Facilitates creating JSON-based chat prompts using an AI model configuration.
-- **OpenAI API Interaction**: Includes functions to fetch models and system interactions via OpenAI's APIs.
-- **Command-Line Functionality**: Provides autocomplete and history features for user inputs using the readline library.
-- **HTTP Requests over SSL/TLS**: Handles HTTP POST and GET operations using OpenSSL for secure connections.
-- **Python Interpreter Plugin**: Executes Python scripts within a C application setting using Python’s C API.
-- **Syntax Highlighting**: Uses ANSI color formatting for syntax highlighting and markdown conversion.
+## Code Structure
+- The application has a simple structure with a single source file.
 
-### Highlights
-- Modular functions ensure clean separation of concerns and improve code readability.
-- Utilizes OpenSSL for secure HTTP requests and JSON-C for efficient JSON handling.
-- The inclusion of various open-source alternatives like Rasa and Botpress are suggested for expanding functionalities.
+## Testing
+- Basic test setup to verify that `main()` returns 0.
+- The test code attempts to call `main()` directly, leading to a multiple definition error.
 
-### Licensing
-All code is licensed under the MIT License, granting permission for free use, distribution, and modification while disclaiming warranties.
+## Issues Identified
+- The test setup is incorrect because calling `main()` directly causes a multiple definition error.
+- Proper testing should involve refactoring the code to separate logic from the entry point.
 
-### Key Improvements
-- Enhanced error handling for JSON operations and API interactions.
-- Optimal memory management practices, including safe allocation and deallocation of resources.
-- The use of modern and secure methods for sensitive information management (e.g., API keys).
+## Recommendations
+- Refactor the application code to isolate logic from `main()` to allow easier testing.
+- Expand the code to include more functionalities and corresponding tests.
+- Review and improve build process and structure for maintainability.
 
-### Open Source Alternatives
-- **Rasa**: A machine learning framework for text-and-voice-based assistant automation.
-- **Libcurl**: A library supporting HTTP requests and SSL/TLS protocols.
-- **GNU Readline**: Provides similar command-line features with history and autocomplete.
+The review will be updated after fixing these issues.
