Deferring means Claude is not given the tool's full details at the start, and finds it through tool search when needed. Before this change, a tool was deferred if it came from an MCP server, was on one set list, or was marked to be deferred. A tool on a second set list is now deferred too.\n\n**Why**\n\nMore tools may now be found through tool search instead of being loaded at the start of a session.\n\n- Area: Tool Search\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
