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_ultrareview_awareness

A Claude Code feature flag, read out of the shipped bundle. It was in the build from v2.1.224 and was gone by v2.1.242.

What it is

A startup tip suggests cloud branch review and shows how many free reviews you have left.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.224.

Presence across releases

ReleasesReadingDeclared typeDefault
2.1.245 – 2.1.250 5 releases never mined — —
2.1.242 – 2.1.243 2 releases not in the build — —
2.1.224 – 2.1.241 17 releases in the build — unknown

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.
