Take over the Lark WebSocket connection from another Claude Code session. Use when Lark messages are going to a different session, or when you want to switch Lark to the current session.
Manage Lark channel access — approve pairings, edit allowlists, set DM/group policy. Use when the user asks to pair, approve someone, check who's allowed, or change policy for the Lark channel.
Set up the Lark channel — save the app credentials and review access policy. Use when the user asks to configure Lark, provides app credentials, asks "how do I set this up" or "who can reach me," or wants to check channel status.
