Notes

• task_guid can be taken from a task URL (guid query param) or from feishu_task_get output.
• comment_id can be obtained from feishu_task_comment_list output.
• attachment_guid can be obtained from feishu_task_attachment_list output.
• user_id_type controls returned/accepted user identity type (open_id, user_id, union_id).
• If no assignee is specified, set the assignee to the requesting user. Avoid creating unassigned tasks because the user may not be able to view them.
• Task visibility: users can only view tasks when they are included as assignee.
• Current limitation: the bot can only create subtasks for tasks created by itself.
• Attachment upload supports local file_path and remote file_url. Remote URLs are fetched with runtime media safety checks and size limit (mediaMaxMb).
• Keep tasklist owner as the bot. Add users as members to avoid losing bot access.
• Use tasklist tools for tasklist membership changes; do not use feishu_task_update to move tasks between tasklists.
