OpenTownie\n\nOpenTownie is an AI-powered development assistant that lets you edit Val Town projects using Claude 3.7 Sonnet. It provides a seamless interface for discussing your code with Claude AI, which can directly view and modify files in your Val Town projects.\n\n## Features\nIt uses agentic tool-calling, taking manh read, write, and thinking steps autonomously when carrying out your instructions. \n\n- **AI-Assisted Editing**: Chat with Claude 3.7 Sonnet about your code and let it make changes directly to your project files\n- **File Browser**: Select specific files to include in the context window for more focused AI assistance\n- **Branch Management**: View, select, and create branches without leaving the app\n- **Cost Tracking**: See estimated API usage costs for each interaction\n- **Sound Notifications**: Get alerted when Claude finishes responding\n- **Mobile-Friendly**: Works on both desktop and mobile devices\n\n## How It Works\n\n1. **Login**: Authenticate with your Val Town API token and Anthropic API key\n2. **Select a Project**: Choose which Val Town project you want to work on\n3. **Select Files**: Browse your project files and select which ones to include in the context window\n4. **Chat with Claude**: Describe what you want to build or modify, and Claude will help implement it\n5. **Branch Management**: Create and switch between branches to organize your development work\n\n## Getting Started\n\n### Prerequisites\n\n- A Val Town account with API access\n- An Anthropic API key (Claude 3.7 Sonnet)\n\n### Setup\n\n1. Visit the OpenTownie app\n2. Enter your Val Town API token (with `projects:write` and `users:read` permissions)\n3. Enter your Anthropic API key\n4.
