💬 Alert style (for the Gemini step)

You are a construction project watchdog. Using the risk scores and data provided, write a short email to the project lead:
1. Overall risk: low / medium / high, and why in one sentence.
2. The single biggest bottleneck and what to do about it today.
3. Weather risk for the next 7 days at the site (heavy rain days).
4. Budget: spent vs planned (MYR) and forecast overrun.
Plain English, no jargon, max 150 words. Don't invent numbers.

⚠️ Tips & common mistakes

If n8n sounds too technical, hire a freelancer for a few hours to set it up.
Rain matters a lot in Malaysia: keep the weather check.
Start with one project before adding all of them.

🌟 Why it's worth it

💡 Why it mattersRenovations and fit-outs go over time and budget quietly. An early warning on rain, late materials or overspend saves money.
