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 can be anchored to a file

Under the hood
Useful2 Signal4
Artifacts

Artifact comments now record the file and content hash they refer to, and when that anchor drifts.

What

Comments on an artifact can now carry the file they refer to and a hash of that file's contents, alongside the existing path and quoted span, so a comment stays tied to what it was written about. The schema also records when the anchor has degraded.

Evidence

anchor_file_sha: Rt.anchorFileSha

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