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.

Clearer refusal when an artifact cannot be created from a type

You'll notice
Useful2 Signal2
Artifacts

When an artifact can't be made from a type in a cloud session, you're pointed at a skill or file instead.

What

When creating an artifact from a type is not available in a cloud session, the refusal now points you at a local alternative ("a skill or a file is fine for that") instead of only saying nothing was created. Failures also report a category alongside the message.

Details
  • The failure payload carries files_error (the message) plus an optional files_error_kind naming the class of failure.
  • A new preamble warns that published artifacts do not honour a <base href> written by the author.
Evidence

so nothing was created; do not retry here

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