Step 2: Parse for details

python3 ~/.claude/skills/_mail-shared/parser.py   ...

Extract from body:

• Service/platform name
• Event type (new login, 2FA enabled, password changed, etc.)
• Location/IP address of the event
• Device/browser info
• Timestamp of the security event (vs. email timestamp)
• Whether it offers a "this wasn't me" link

Step 3: Flag suspicious events

Raise concern if:

• Login from unexpected location or country
• Multiple password reset emails in a short window
• 2FA changes you don't remember
• "New device" login you don't recognize
• Account recovery initiated you didn't start

Output Format

Security Events — [PERIOD]

Group by type:

• 2FA Changes
• Password Resets
• New Device Logins
• Login from new location
• Suspicious Activity Alerts

For each event: Service | Event | Location/Device | Date | Status (read/unread)

Flag: any unread security alerts (you may not have seen them). Flag: any events from unexpected locations. Note: total count by account/service.
