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 Code v2.1.238

Republishing a page read back from the server is refused

You'll notice
Useful2 Signal2
Artifacts

Claude can no longer republish a page it read back from the server; it must use the authored source.

What

If Claude fetches an already-published page and tries to publish those bytes again, the publish validator now stops it and says to republish from the HTML or payload that was authored, not from what was read back.

Details
  • The check looks for the marker element the server injects into published pages.
  • Runs on every publish, with no setting to skip it.
Evidence

not your local copy; republish from the HTML (or payload) you authored, never from bytes you read

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