Agent Metadata
Known Gotchas

- ⚠ Feishu and Lark are the same product but may have different API endpoints for CN vs international
- ⚠ App permissions must be explicitly configured in Feishu Open Platform dashboard
- ⚠ Feishu uses Rich Text Format (Feishu Doc format) which differs from Markdown — content formatting differs
