Feishu Push

It handles the token dance (app_id and app_secret to tenant_access_token) and supports text, cards, images, files, and interactive content. You'll need a Feishu bot app with im:message permissions and users within scope. The skill wraps both curl and node approaches, which is practical since you need JSON parsing anyway. One thing to watch: it only works with user_id as the receive_id_type, so you can't target open_id or union_id directly. Useful when you're building workflows that need to notify specific people in a Feishu workspace without manually handling OAuth flows.
