🛠️ Installation

1. Clone this repository:

   git clone https://github.com/doriandarko/claude-engineer.git
   cd claude-engineer
   

2. Install the required dependencies:

   pip install -r requirements.txt
   

3. Set up your environment variables:

   • Create a .env file in the project root directory
   • Add the following environment variables:

     ANTHROPIC_API_KEY=your_anthropic_api_key
     TAVILY_API_KEY=your_tavily_api_key
     

4. Set up the virtual environment for code execution: Engineer will create a virtual environment to run code the first time it executes a piece of code. This is just for you if you want to run the main script in a virtual environment rather than in your default one.

   python -m venv code_execution_env
   source code_execution_env/bin/activate  # On Windows, use: code_execution_env\Scripts\activate
   pip install -r requirements.txt
   deactivate
   

🔧 Virtual Environment Setup

Claude Engineer uses a dedicated virtual environment for code execution to ensure isolation and security. The virtual environment is automatically created the first time you run a piece of code. However, if you want to set it up manually or customize it, follow these steps:

1. Create the virtual environment:

   python -m venv code_execution_env
   

2. Activate the virtual environment:

   • On Windows:

     code_execution_env\Scripts\activate
     

   • On macOS and Linux:

     source code_execution_env/bin/activate
     

3. Install the required dependencies:

   pip install -r requirements.txt
   

4. Deactivate the virtual environment when you're done:

   deactivate
   

The code_execution_env virtual environment will be used for all code execution tasks, ensuring a consistent and isolated environment for running user code.

🚀 Usage

Run the main script to start the Claude Engineer interface:

python main.py

Once started, you can interact with Claude Engineer by typing your queries or commands. Some example interactions:

• "Create a new Python project structure for a web application"
• "Explain the code in file.py and suggest improvements"
• "Search for the latest best practices in React development"
• "Help me debug this error: [paste your error message]"
• "Analyze this image and describe its contents"
• "Execute this Python code and analyze the results"
• "Read multiple files: file1.py, file2.py, file3.py"

Special commands:

• Type 'exit' to end the conversation and close the application.
• Type 'image' to include an image in your message for analysis.
• Type 'reset' to reset the entire conversation without restarting the script.
• Type 'automode number' to enter Autonomous mode with a specific number of iterations.
• Type 'save chat' to save the current chat log.
• Press Ctrl+C at any time to exit the automode and return to regular chat.

After each interaction, Claude Engineer will display:

• Token usage (input, output, and total) for the current model
• Remaining context window size

Code Execution and Process Management

Claude Engineer now supports executing code in an isolated 'code_execution_env' virtual environment:

1. Use the execute_code tool to run Python code safely in the isolated environment.
2. Long-running processes can be managed using the process ID returned by execute_code.
3. The CODEEXECUTIONMODEL analyzes execution results and provides insights.

Using Different AI Models

Claude Engineer utilizes multiple specialized AI models:

• MAINMODEL: Claude 3 or Claude 3.5 for general interactions
• TOOLCHECKERMODEL: Validates tool usage and outputs
• CODEEDITORMODEL: Performs specialized code editing tasks
• CODEEXECUTIONMODEL: Analyzes code execution results

The script automatically selects the appropriate model based on the task.

🤖 Improved Automode

The enhanced automode allows Claude to work autonomously on complex tasks with greater efficiency and control. When in automode:

1. Claude sets clear, achievable goals based on your request.
2. It works through these goals one by one, using available tools as needed.
3. Claude provides regular updates on its progress, including the current iteration count.
4. Automode continues until goals are completed or the maximum number of iterations is reached.
5. You can specify the maximum number of iterations when entering automode (default is 25).
6. Claude dynamically adjusts its approach based on progress and obstacles encountered.
7. The TOOLCHECKERMODEL validates tool usage and outputs for increased reliability.

To use automode:

1. Type 'automode number' when prompted for input, where number is the maximum number of iterations.
2. Provide your request when prompted.
3. Claude will work autonomously, providing updates after each iteration.
4. Automode exits when the task is completed, after reaching the maximum number of iterations, or when you press Ctrl+C.

📊 Enhanced Diff-based File Editing

Claude Engineer now supports an improved diff-based file editing system, allowing for more precise and controlled modifications to existing files. The new workflow includes:

1. Reading the entire content of a file using the edit_and_apply function without providing new content.
2. Applying changes to the file using the edit_and_apply function with new content, which shows a detailed diff of the proposed changes.
3. Utilizing the CODEEDITORMODEL for specialized code editing tasks, ensuring high-quality modifications.

When editing files, Claude will:

1. Show a detailed diff of the proposed changes, highlighting additions, removals, and unchanged lines with color coding using the Rich library.
2. Focus on adding new code or modifying existing code without unnecessarily removing functionality.
3. Provide a summary of lines added and removed.
4. Apply changes carefully to avoid duplicates and unwanted replacements.
5. Support various editing scenarios, including targeted changes, appending content, inserting at the beginning, and replacing entire file contents.
6. Use the CODEEDITORMODEL to ensure code changes adhere to best practices and maintain consistency.

This feature enhances Claude's ability to make targeted improvements to your codebase while maintaining the integrity of existing functionality.

🧠 Dynamic System Prompt

The system prompt is now dynamically updated based on whether the script is in automode or not. This allows for more tailored instructions and behavior depending on the current operating mode:

1. In regular mode, Claude focuses on providing helpful responses and using tools as needed.
2. In automode, Claude is instructed to work autonomously, set goals, and provide regular updates on progress.
3. The system prompt adapts to the specific task at hand, optimizing Claude's performance for each scenario.
4. The system prompt now includes file context for enhanced token management.

The dynamic system prompt enhances Claude's ability to adapt to different scenarios and provide more relevant assistance.

📊 Token Management and Visualization

Claude Engineer now features improved token management and visualization:

1. Enhanced token management using file context in the system prompt.
2. Improved token visualization using a table format.
3. Display of input, output, and total token usage for each model interaction.
4. Visualization of remaining context window size.

These improvements provide better insights into token usage and help manage conversations more effectively.
