Claude Code v2.1.246

Publish-over-an-existing-page failures now distinguish a proxy block from an HTTP error

You'll notice
Useful2 Signal2
Artifacts

Publishing over an existing page now says whether a proxy block or an HTTP error stopped the check.

What

Before overwriting a published page, Claude Code reads it to confirm it is not a certified review page. If that read is blocked by the sandbox proxy, the failure message now says whether retrying is worth it.

Details
  • A transient content-scan denial advises reading the page again or publishing fresh.
  • Any other proxy denial drops retry advice entirely and says "Publish a fresh artifact instead (omit url and use a new file_path)."
  • The older HTTP 403 and generic-status wording is now used only for failures that were not proxy denials.
  • Unconditional on the publish-overwrite verification path.
Evidence

content_scan_transient

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