What problem does it solve? Managing enterprise email inside WeCom (企业微信) through conversation is fragmented: users need to compose messages, resolve recipients from the contacts directory, attach files, embed inline images, and search large mailboxes without touching the mail client. This Skill routes all of those operations through the wecom-cli tool with strict workflows, output formats, and security guardrails. ## Core Features & Use Cases - Full mail lifecycle: Send new emails, reply (including reply-all), and forward with automatic subject prefix construction and deduplication (回复:/转发:/Re:/Fwd:). - Search and read: Multi-condition mail search (keywords, sender, time range, unread, folder, tag, attachments, star, importance) with pagination, plus full detail retrieval including body, attachments, inline images, and calendar/meeting info. - Schedule and meeting emails: Send calendar invitations and meeting bookings via email with repeat rules, reminders, and meeting options. - Security guardrails: Prompt-injection detection in mail bodies, social-engineering identification, external-recipient warnings, and refusal to embed executable code. - Use Case: Ask the assistant to "reply to all on the Q2 report email with the updated figures attached" — it locates the mail, resolves recipients, writes a Markdown body, previews the message, and sends it via wecom-cli. ## Quick Start Ask the assistant to send an email to a colleague by name with a subject and body, and it will resolve the recipient, preview the message, and deliver it through wecom-cli.
