An artifact is a file or document Claude produces for you. Before, the guidance told Claude to prefer artifact types over skills when making `.pptx` (PowerPoint) or `.docx` (Word) files. A skill is a packaged set of instructions Claude can follow.\n\nThe guidance now names a second artifact type. Under one condition it also lists `.xlsx` (Excel) spreadsheets. Without that condition the list stays `.pptx` and `.docx`.\n\n**Why**\n\nWhen the condition holds, spreadsheet requests are steered toward an artifact type instead of a skill.\n\n- Area: Artifacts\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
