What

Claude Code includes switches that Anthropic's servers can turn on or off for each account, used to try out features before they are released. This build adds seven new names to the lists of switches it tracks:

Of these, tengu_steady_wilkes is off unless it is switched on remotely.

Why

New switches usually mean new experiments are being prepared. What these ones control is not described, so there is nothing for a reader to use or change yet.

What has happened since
Flag reading moved The flag server now returns nothing at all, having stopped carrying it for tengu_brisk_kiwi, 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.
