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 Listing: First-Session Confirmation Required

The first action: "list" call within any session now always requires user confirmation, even if the user has previously allowed artifact listing. A permission prompt appears: "Claude wants to list your published artifacts (titles and links from your earlier sessions)."

Details
  • suppressAlwaysAllowRule is set, so "always allow" rules do not bypass this first-listing ask
  • Subsequent listings in the same session proceed without an additional prompt
  • Results are now formatted as "N published artifact(s) (most recent first):" with title, URL, and last-updated date per entry
  • A note is appended if the result set was truncated: "(More may exist — pass a higher limit (up to 50); artifacts not updated recently can be beyond the listing window.)"
Evidence

First-listing confirmation (search for "First artifact listing this session requires confirmation")

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