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 v2.1.234

Publishing unwraps an artifact page that got nested inside another

You'll notice
Useful3 Signal1
Artifacts

Publishing an artifact strips an already-wrapped page so you don't get a page inside a page.

What

If the HTML being published already carries Claude Code's own generated page wrapper around the real content, publishing now strips it, repeatedly, up to a depth limit, so you do not get a page inside a page.

Details
  • The wrapper is recognised by its shape: a doctype, a head, at most two inline scripts and a style block around the payload.
  • Reported as nested_page_repaired when fully unwrapped, or nested_repair_partial when the depth cap is hit first.
Evidence

nested_page_repaired

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