데브허브 | DEVHUB | BigTool: Agents with large number of tools
Agents dynamically direct their own processes and tool usage. But how many tools can agents reliably use? A large number of tools can introduce cognitive burden, making it challenging for agents to select the right one. BigTool is a prebuilt LangGraph agent that works with large numbers of tools using a simple idea: use a search to retrieve and bind only the most relevant tools to the agent for a given task. We show this working with a simple vectorstore that embeds tool descriptions and uses semantic search to fetch the most relevant tools based upon the user's request. We show this works well even with low capacity local models, like Qwen-14-b.
