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.

Clearer artifact publish failures, including a refused auto-publish

You'll notice
Useful3 Signal2
Artifacts

Artifact publish failures now explain refusals and tell you the reserved slug so you can retry.

What

Publishing an artifact now explains a 422 refusal directly instead of the old "server kept reporting missing content" loop message, a cancelled publish tells you the slug it reserved so you can retry to it, and an auto-published edit that was not approved now says so and points at the artifact owner.

Details
  • The 422 message states the deploy was refused and that the re-check before re-sending also failed.
  • A new telemetry event prepare_rerun_failed carries prepare_status for that case.
  • The declined auto-publish is a distinct outcome, auto_mode_declined, whose text says the edit was not approved for automatic publishing and that the artifact owner can make the change from their own session.
Evidence

prepare_rerun_failed

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