CLAUDE_CODE_ARTIFACT_TYPE_CLOUD_CREATE or its flag would unlock cloud type creation; both fall back off.
Artifact types (listing and describing available types, filtering by type, both treated as read-only for permissions) remain behind CLAUDE_CODE_ARTIFACT_TYPES or the flag tengu_cobalt_plinth_larch. New here is a second switch specifically for creating an Artifact from a type while in a cloud session: CLAUDE_CODE_ARTIFACT_TYPE_CLOUD_CREATE or the flag tengu_cobalt_plinth_hazel. Both fall back to off, so on a stock cloud session this is closed.
- Local sessions allow type-based creation unconditionally; only remote sessions need the second gate, on top of types being enabled at all.
- The decision is frozen once per session and then selects between the working prompt and the refusal wording.
- When closed, publishing with a type URL returns a sentence aimed at the model telling it not to retry there and to give the user the type's link instead.
Starting a new Artifact from a type isn't available in this cloud session right now, so nothing was created; do not retry here., tengu_cobalt_plinth_hazel
Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Read once, for one account on one subscription tier, against v2.1.242. It isn't a statement about your account. What a flag value here can and cannot tell you
A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
