1. **Multi-Category Classification and Prioritization**: Given a batch of 50 synthetic emails (ranging from marketing newsletters and automated shipping notifications to urgent technical support requests and internal meeting invites), classify each into one of five categories (e.g., "Urgent Support," "Billing," "Marketing," "Internal," "Spam") and assign a priority score from 1 to 5 based on the perceived time-sensitivity of the content.

2. **Sentiment-Based Escalation Detection**: Analyze a series of customer service inquiries regarding a delayed product shipment. Identify the sentiment of each email (e.g., "Frustrated," "Neutral," "Satisfied") and flag specific messages where the sentiment is "Highly Frustrated" or contains "Legal Threat" keywords for immediate human escalation.

3. **Action Item and Deadline Extraction**: Process a long-form project kickoff email containing various discussion points, updates, and requested tasks. Extract a structured list of actionable items, the specific person assigned to each task (using synthetic names), and any mentioned deadlines into a JSON format.

4. **Thread Summarization and Status Tracking**: Provide a synthetic thread of 10 back-and-forth emails regarding a software bug report. Generate a concise three-sentence summary that captures the initial problem, the troubleshooting steps taken so far, and the current "blocker" or next step required to resolve the issue.

5. **Entity Extraction and Routing**: Analyze a batch of synthetic invoices and purchase orders. Extract key entities including "Vendor Name," "Total Amount," "Order ID," and "Due Date." Based on the "Total Amount," automatically route the data to the "High-Value Procurement" department if the amount exceeds a synthetic threshold of $5,000.
