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.

Artifact input validation checks for a login-free action before demanding a login

You'll notice
Useful3 Signal3
Artifacts

Artifact actions that work entirely locally no longer demand a claude.ai login first.

What

Artifact input validation used to require a claude.ai account check before dispatching to any action. It now resolves the action's handler first and skips the login requirement when that handler declares itself local-only.

Details
  • The same reordering appears in a second validation path in the same tool.
  • The only handler carrying the marker declares actions: ["preview"], and the preview action is itself gated, so nothing else reaches the relaxed path.
Evidence

localOnly: !0,

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