Feishu Lark

This sends messages to Feishu (ByteDance's workplace chat for China) and Lark (the international version) using either webhooks or the full Bot API. You get plain text, rich text posts with formatting and links, and interactive cards with buttons and structured layouts. The webhook approach is dead simple: create a bot in your group settings, paste the URL, and curl away. The App Bot route gives you more power like at-mentions, image uploads, and posting to multiple chats, but requires OAuth setup through the developer console. Useful for marketing announcements, team alerts, or any automated notifications into Chinese corporate chat systems. The skill includes signature verification for secured webhooks and a full reference for card templates with color-coded headers.
