Anthropic Just Changed the Game (again)

By Samuel Gregory

About this video

Context overload got you down? Fear not! Anthropic just dropped Tool Search in Claude Code and the desktop app, slashing token usage like a hot knife through butter. Key takeaways: * Tool Search dynamically loads tools, saving precious context. * It kicks in when MCP tool descriptions exceed 10% of context. * Lazy loading for MCP servers is finally here! * It's live in Claude Code and the desktop app (make sure you update!). * I might have had to tweak settings.json (but hopefully you won't need to). Check out how I got my token usage down and why it matters for staying productive!
