New in Agent Builder: all new agent chat, file uploads + tool registry

LangSmith Agent Builder has been significantly updated to enhance user interaction by incorporating a central "Chat" agent that operates like a teammate, allowing for ad hoc tasks and the creation of specialized agents. The update includes features such as the ability to directly upload files like CSVs, images, and text files into the chat for various tasks, and manage all tools from a single registry with admin controls. Users can now transform any conversational task into a recurring agent with a single click, and the Chat agent can access all connected tools such as Slack, Gmail, and others to perform tasks seamlessly. This allows for complex, multi-step operations without needing separate dedicated agents, and every conversation is saved for future use, enabling users to create agents from past interactions. Additionally, the update simplifies tool management, ensuring that only workspace administrators can add new tools, keeping the system organized and secure.
