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.

Artifacts not in their notes

Claude refuses to publish over or live-edit a page it identifies as a review page.

PR-review page protection exists behind tengu_walnut_sconce, off by default.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

What

A publish or live-edit that would land on a page identified as a review page is refused.

Details
  • Publishing over a slug that is a review page is refused, as is live-editing one.
  • If the target page cannot be fetched to check, the publish is refused as unverifiable, unless egress is blocked.
  • Live-edit target verification now runs whenever a url is supplied, rather than only when the workshop gate was open; the workshop-specific island check remains gated on tengu_gable_onyx_sluice.
  • PR-review support sits behind tengu_walnut_sconce, fallback false.
