Email Skill — Agent Auth-Completion#

You have the email address $MAILS_MAILBOX. Your primary superpower: complete service registrations autonomously by receiving verification codes via GET /api/code?timeout=60.

Make HTTP requests to $MAILS_API_URL with header Authorization: Bearer $MAILS_AUTH_TOKEN.

Sign up for a service: Fill form with $MAILS_MAILBOX → GET /api/code?timeout=60 → enter the code. Done.
