lark-im

Use the lark-cli im +messages-send shortcut with --chat-id for groups or --user-id for direct messages, plus --text, --markdown, or media flags like --image and --file. Sending uses bot identity and requires the im:message:send_as_bot scope.

Run lark-cli im +messages-search with --query and optional filters like --chat-id, --sender, --start, and --end. It is user-identity only and automatically fetches full message content and chat context for the results.

Message sending and group creation are bot-only, while message search is user-only. For adding members or updating groups, prefer the identity that owns or administers the chat, since bot visibility limits often cause errors like 232043 or 232024.

Error 232043 means the bot and target users are mutually invisible. Create the group with the bot first, then add other users with a user-identity chat.members create call instead of passing them in --users during creation.

Yes, use lark-cli im +messages-resources-download with the message_id, file_key, and --type image or file. The file_key comes from message content returned by +chat-messages-list, and files over 100 MB cannot be downloaded.

When fetching messages with bot identity, the bot may lack contact visibility for the sender, so names cannot be resolved. Expand the app's visibility range in the Lark Developer Console or fetch messages with --as user instead.
