DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.246

Artifact guidance routes decks and documents through the type list first

Under the hood
Useful3 Signal3
Artifacts

Asking for a deck, document or design now sends Claude to check artifact types first.

What

When you ask for a slide deck, presentation, a document or report for others to read, or a visual design, Claude Code is now told to look up the available artifact types before loading a skill or writing a file, and to prefer a listed type even over a skill that would emit a .pptx or .docx.

Details
  • The file-format route is now described as correct only when you actually want the file format itself.
  • Questions about which types or templates exist trigger a lookup before answering.
  • Where creating from a type is not available in the session, the model offers to make it another way instead.
Evidence

prefer a listed type that fits, even over a skill that would produce it as a file format such as .pptx or .docx

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
