It scores your health activities and assigns a dynamic \"Bounty\" reward.\n\n## How it works\n1. **Fetch Data**: Retrieves your current \"Bounty\" from Google Sheets.\n2. **AI Analysis**: A central AI Scorer evaluates your report (meals, workouts, or injuries) and assigns a score from 0-100.\n3. **Logic**: JavaScript calculates the bounty increase based on the AI's score.\n4. **Routing**: The Switch node routes you to a specialized agent (Chef, Samurai, Doctor, or Navigator).\n5. **Logging**: Saves the conversation to Google Sheets for progress tracking.\n\n## Setup steps\n1. **Google Sheets**: Create a sheet with two tabs:\n - `Profile` (Columns: ID, Total_Bounty)\n - `Log` (Columns: Date, Crew, Inquiry, Response)\n2. **Spreadsheet ID**: Replace `YOUR_SPREADSHEET_ID` in all 6 Google Sheets nodes.\n3. **Credentials**: Connect your Google Sheets and AI (OpenRouter/OpenAI) accounts."
