DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / Feature flags

tengu_bridge_host_declined_end

A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.238, including the newest one read.

What it is

Three new remote-bridge switches appear, covering a retry after a rejected token refresh and two unread ones.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.238.

2.1.238 – 2.1.243 6 releases in the build — bool:true

A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

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.

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.
