What
Tool search is how Claude finds and loads tools that are held back until needed. Before, it could only tell Claude that a requested tool was already available in the conversation. It can now also say that a tool is being added to the conversation, and that a notice following the search result explains how to call it.
Why
Claude is less likely to keep searching for a tool that is already on its way.
