Unclear What turns on the .xlsx part of the guidance is not known.
What
Claude Code gives the model guidance about artifact types. 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.
The 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.
Why
When the condition holds, spreadsheet requests are steered toward an artifact type instead of a skill.
