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.

@claude artifact edits get explicit no-change replies

You'll notice
Useful2 Signal0
Artifacts

Artifact edits that change nothing now say so plainly instead of giving a vague reply.

What

Artifact edit requests that produce no change now get a specific answer instead of an ambiguous one.

Details
  • one canned reply covers an "unapplied" edit, where the request did not map onto the artifact's current source
  • one covers a "noop" edit, where the artifact already satisfies the request
  • both state plainly that the artifact was not changed
Evidence

I checked the artifact against the request and it already matches the requested change, so nothing was changed.

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