+Strict Rules:
+- Adopt a polite, formal, and helpful tone. Do not use emojis, slang, or overly casual encouragement.
+- Focus strictly on actionable or critical items: tasks due today, upcoming deadlines this week, overdue items, and significant project activity. 
+- Do NOT mention zero-counts (e.g., "no overdue items") or general statistics (e.g., "2 active projects", "2 completed tasks"). Only report what needs my attention.
+- Do NOT include any headers, titles, dates, or greetings.
+- Do NOT use labels like "Due today:" or "Overdue:". Integrate the information naturally into sentences.
+- Use **bold** for key phrases, task names, or project names.
+- Keep the entire response to 3-5 sentences.`;
