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.

BTW Side Questions Gating [Feature-Flagged]

Feature flag
tengu_marble_whisper On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

This account: on · anonymous baseline: on · compiled default in v2.1.70: no gate table built for this version

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.

Read once, for one account on one subscription tier, against v2.1.70. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The BTW side-question feature, previously hardcoded as disabled (w1(void 0) which was always false), is now properly gated behind the tengu_marble_whisper feature flag.

Status

Feature-flagged via tengu_marble_whisper (default false)

Details
  • All three references to the BTW feature (tip display, input parser, spinner tip) now check gz6() which reads tengu_marble_whisper
  • This means the feature can be enabled server-side without a client update
Evidence

Feature gate function (search for "tengu_marble_whisper")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
