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.

Artifacts

Artifacts accept a note field, ignored when creating a URL artifact.

note
What

Artifacts now recognise a note field alongside favicon, label and description. On a URL-type create call it is ignored, as those other fields already are, because only type and title apply at creation time.

Evidence

["favicon", "label", "note", "description"]

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