The artifact tool's copy_from action is now gated by a new Are() capability check in addition to the existing assets capability, stored as frozenCopyFrom. The gate reads the tengu_cobalt_plinth_samphire flag, which is new to this build, so the action's enum entry and description only appear when both checks pass.
The artifacts tool's permission-check dispatcher recognizes the new copy_from action, letting Claude copy assets from one published artifact into another server-side, but the action is also guarded by an account-level check that currently resolves to disabled: calling it returns an explicit "action copy_from is not enabled for this account" error.
tengu_cobalt_plinth_samphire Off in both readingsThe 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.

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.

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.
