This bridge allows users to interact with local AI coding agents directly from Feishu/Lark messaging. It forwards messages to Claude Code or Codex CLI, displays streaming text and tool calls as real-time cards, and maintains separate sessions per chat thread. The tool supports workspace switching, image/file uploads, interactive commands, and queuing of messages during active runs. Users install a PersonalAgent app in Feishu and bind it via QR code to their local agent setup.
