Source Intelligence

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.

Document artifacts: new style picker, no status chip

You'll notice
Useful3 Signal3
Artifacts

Published documents lose the status header and gain a style menu that previews each option.

What

Published documents lost their owner/date/status header block, which is now left to the artifact's own chrome, and the paragraph-style dropdown was replaced with a custom menu that previews each option in its own type style. Re-picking the style a block already has is now a no-op, which stops the block being rebuilt and a pinned comment thread being detached from it.

Details
  • The menu supports Escape and arrow keys and restores focus to the toggle button when closed.
  • The toolbar no longer fades: it sits on its own band with a border, and Save is a filled primary button.
  • Typography was re-specified on a 28px baseline with a 34em line measure, plus a reader-only pretty text wrapping mode.

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