Step 1: Get Message-ID

Please provide the email Message-ID

💡 Quick method (recommended):
In Mail.app: Select email → Press shortcut (⌘⇧C) → Message-ID copied
See README "Setup Mail Quick Action" section if not configured

Step 2: Read Email Data

email_data = mcp__mail__read_email(message_id)

Step 3: Analyze Attachments

Check if email is part of thread:

thread_paths = mcp__mail__get_thread_paths(message_id)
if len(thread_paths) > 1:
    # This is a thread
    # Ask user: analyze this email only or entire thread?

Step 4: Classify Attachments

Importance levels:

🚨 High Importance

• Government notices (HMRC, IRS, tax documents)
• Legal documents (contracts, agreements, NDAs)
• Financial documents (invoices, receipts, bills)
• Certificates (licenses, permits)
• File type: .pdf from official sources

⚠️ Medium Importance

• Technical documentation
• Reports and analysis
• Spreadsheets and presentations
• File types: .pdf, .docx, .xlsx, .pptx

💡 Low Importance

• Images (unless specified as evidence)
• Signatures
• Plain text files
• File types: .png, .jpg, .txt, .mov

Step 5: Choose Mode Based on Context

Auto Mode triggers:

• Sender contains: "hmrc", "irs", "tax", "court", "legal"
• Subject contains: "invoice", "contract", "urgent", "deadline", "tax"
• High-importance attachments detected

Interactive Mode:

• Mixed importance attachments
• User seems uncertain

Quick Mode:

• Only low-importance attachments
• User just browsing

Step 6: Execute Based on Mode

Quick Mode: Just list and classify

Interactive Mode:

Step 7: Extract and Analyze (if applicable)

# Extract attachments
attachments = mcp__mail__extract_attachments(message_id, filenames)

# Analyze content
for file_path in extracted_files:
    content = read_file(file_path)
    analysis = analyze_content(content)

Step 8: Cleanup

CRITICAL: Always cleanup after analysis
