Title:
Gamify fitness tracking with AI multi-agents and Google Sheets
Overview
This template transforms fitness tracking into a gamified pirate adventure using AI multi-agents. It scores your health activities and assigns a dynamic "Bounty" reward.

How it works
Fetch Data: Retrieves your current "Bounty" from Google Sheets.
AI Analysis: A central AI Scorer evaluates your report (meals, workouts, or injuries) and assigns a score from 0-100.
Logic: JavaScript calculates the bounty increase based on the AI's score.
Routing: The Switch node routes you to a specialized agent (Chef, Samurai, Doctor, or Navigator).
Logging: Saves the conversation to Google Sheets for progress tracking.

Setup steps
Google Sheets: Create a sheet with two tabs:
Profile (Columns: ID, Total_Bounty)
Log (Columns: Date, Crew, Inquiry, Response)
Spreadsheet ID: Replace YOUR_SPREADSHEET_ID in all 6 Google Sheets nodes.
Credentials: Connect your Google Sheets and AI (OpenRouter/OpenAI) accounts.
