139 Mail Efficiency Assistant

What it solves

When email becomes the entry point for daily work, threads, attachments, drafts, and todos are scattered across pages. The 139 Mail Efficiency Assistant turns common mailbox operations into agent-callable workflows: find mail by filters, read bodies and attachments, summarize content, draft and send replies, and convert mail items into calendar todos.

How it works

The core capabilities cover mail workflows and calendar todos:
- Search and reading: locate mail by keyword, date range, sender/recipient, and read/unread status, then read bodies and attachments.
- Sending and drafts: build a draft first, confirm before sending; supports attachments and contact matching.
- Organization: mark read/unread, star, or move mail between folders.
- Todos: extract tasks from mail, add them to the 139 calendar, and query by time or title.
In practice, the skill first confirms the bound account, then calls the matching workflow. Irreversible actions such as sending, adding todos, or moving mail should show the full change and wait for explicit confirmation.

Boundaries

It is intended for 139 mailbox tasks. Deleting mail, moving drafts, and clearing labels are not supported. Write operations rely on confirmation state, and local-file workflows require a PC client environment.
