tengu_walnut_sconce

flag gone JSON

A Claude Code feature flag, read out of the shipped bundle. It was in the build from v2.1.218 and was gone by v2.1.268.

An alternate PR-review description exists but you'll always see the original one.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.219.

Two arms, because they disagree: this account is the one account this site reads and anonymous is a baseline with no identity attached. A reading says nothing about your account, and off cannot rule out a rollout both readings sit outside of. What these readings can and cannot show.

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the feature flag does. All feature flags.
