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.

Artifact comments now mark which comments were sent to Claude

You'll notice

Artifacts

Comment rows are now labelled "sent to you" so you can tell requests apart from side chatter.

What

Comment rows carry an explicit label when the comment was addressed to Claude, so it is clear which parts of a thread are a request to you and which are other people talking to each other.

Details
  • Rows can show a ", sent to you" label, with an "awaiting reply" variant and a variant for when the status cannot be read.
  • Threads containing such comments are sorted to the top of the list, and the header count mentions them.
  • The tool description now states that only labelled comments are addressed to Claude.
  • The anti-injection preamble gained explicit rules that the attribution bracket only ever appears at the start of a row.
Evidence

Threads with comments sent to you are listed first; list order is not chronological.

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