Scored across 4 tools
Tools have distinct names but functional overlap: lark_chat_progress and lark_chat_stream both involve streaming card updates, and lark_chat_watch also opens a streaming card on receiving messages. This could cause confusion for an agent selecting a tool for card operations.
All tools follow a consistent 'lark_chat_<noun>' pattern in snake_case, making them predictable and easy to distinguish by name alone.
With 4 tools, the set is slightly small but covers the essential functions of session management, progress updates, streaming cards, and message watching, which is reasonable for a focused chat integration.
The tool surface lacks basic messaging operations like sending plain text or media, and there is no explicit delete or edit. While progress and stream cover some updates, there are notable gaps for a general chat server.
