Agents cannot safely operate Feishu/Lark without juggling bot APIs, user cookies, and OAuth tokens across dozens of workspace surfaces.
Who is it for?
Indie teams and CN-market builders who already live in Feishu/Lark and want agent-driven docs, tables, and chat automation.
Skip if: Slack-only stacks, builders who refuse user-session cookies, or anyone needing a five-minute single-key setup.
