Relationship to the macOS automation skill

• Use automating-mac-apps for permissions, shell, and UI scripting guidance.
• PyXA Installation: See automating-mac-apps skill (PyXA Installation section).

Core Framing

• Mail dictionary is AppleScript-first; discover in Script Editor.
• Objects are specifiers: read via method calls (message.subject()), modify via assignments (message.readStatus = true).
• ObjC bridge available for advanced filesystem operations.

Workflow (default)

1) [ ] Ensure Mail configured and automation permissions enabled. 2) [ ] Discover terms in Script Editor (Mail dictionary). 3) [ ] Prototype minimal AppleScript command. 4) [ ] Port to JXA with defensive checks. 5) [ ] Use batch reads for performance. 6) [ ] Use UI scripting for signature and UI-only actions.

Quick Start Examples

Read inbox (JXA):

const Mail = Application('Mail');
const message = Mail.inbox.messages[0];
console.log(message.subject());

Compose message (JXA):

const msg = Mail.OutgoingMessage({
  subject: "Status Update",
  content: "All systems go."
});
Mail.outgoingMessages.push(msg);
msg.visible = true;

PyXA alternative:

import PyXA
mail = PyXA.Mail()
inbox = mail.inboxes()[0]
message = inbox.messages()[0]
print(f"Subject: {message.subject()}")

Validation Checklist

• [ ] Automation permissions granted (System Settings > Privacy > Automation)
• [ ] Inbox access works: Mail.inbox.messages.length
• [ ] Message property reads return expected values
• [ ] Composition creates visible draft
• [ ] Batch operations complete without errors

When Not to Use

• For cross-platform email automation (use IMAP/SMTP libraries)
• For bulk email sending (use transactional email services like SendGrid)
• When processing untrusted email content (security risk)
• For non-macOS platforms
