What probably matters to youSection of the release
A full design-canvas skill publishing pan-and-zoom artboards with an in-page editor needs a flag that falls back to false plus a capability-advertising Artifact tool.
What
A large new bundled skill drafts designs as .dc.html artboards laid out on a single pan-and-zoom canvas and publishes them as an Artifact, with an editor built into the published page. Saving republishes for everyone only where the artifact grants the self-write capability; otherwise the page is view plus PNG and PDF export. It registers a design slash command. Off in this build: it needs tengu_ethereal_nova, which falls back to false, and an Artifact tool that advertises capabilities.
Details
ships as a skill document plus a canvas seeding script and a precompiled editor page payload
Evidence
Draft a design on a canvas Artifact — editable where saving is enabled (Claude Design preview)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.
This account: off · anonymous baseline: off · compiled default in v2.1.229: off
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.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Flag reading movedThe flag server now returns off for tengu_ethereal_nova, read as this account.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.
