Some tools can only be called from a script run through the REPL tool, which lets Claude run code that calls other tools. When a search matches such tools, tool search now adds a note listing them, with a sketch of how each is called, and tells Claude to call them from the REPL tool.\n\nThis only happens when REPL mode is on.\n\n**Why**\n\nClaude can now find tools that only work inside scripts, instead of missing them because tool search does not load them.\n\n- Area: Tool Search\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
