Can it handle folders with hundreds of emails?

Yes, the skill is optimized for high-volume folders (300-600+ emails) by using background agents and pagination to prevent token limit issues.

What happens if there are duplicate emails in the folder?

The skill includes duplicate handling logic that preserves the first occurrence and adds a count suffix (e.g., x2, x3) to subsequent identical subjects from the same sender on the same day.

Does this skill require a Microsoft 365 account?

Yes, it utilizes the MS365 MCP integration which requires you to authenticate via mcp__ms365__login to access your Outlook data.

How does the skill identify reimbursement emails?

The skill scans email subjects and sender names for specific keywords such as 'invoice', 'receipt', 'billing', and 'order confirmation' to automatically flag them with a [$] marker.

Where are the archived files stored?

By default, the skill generates and saves Markdown files to a specific local directory: ~/Desktop/jluo41-repo/3-Chronile/Emails/MonthIndex/.
