What problem does it solve? It lets an AI assistant safely operate a Feishu (Lark) mailbox on your behalf—reading, searching, drafting, replying, forwarding, and organizing email—while enforcing strict confirmation rules so no message is ever sent without your explicit approval. ## Core Features & Use Cases - Full mail lifecycle: Triage the inbox, read single messages, batches, or whole threads, then compose, reply, reply-all, or forward with HTML bodies, attachments, inline images, signatures, and calendar invites. - Draft-first safety workflow: All send-type commands save drafts by default; actual sending, deletion, and rule changes require explicit user confirmation, and delivery status can be verified after sending. - Organization and automation: Modify labels, read state, and folders, soft-delete messages, manage inbox rules, use mail templates, recall sent mail, and handle read-receipt requests. - Use Case: Ask the assistant to summarize today's unread inbox, draft an HTML weekly report reply to your manager using an official template, review the draft link in Feishu Mail, then confirm sending and check delivery status. ## Quick Start Ask the assistant to show a summary of my unread inbox and draft a reply to the latest message from my manager.
