Source Intelligence

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.

One state variable now tracks which input overlay is showing

Under the hood
Useful2 Signal2
Elsewhere

One state value tracks which input overlay is up, so search or history dismisses it.

What

The chat input replaced its help-overlay on/off flag with a single value that is empty, "help", or "proactivity", so opening search or history dismisses whichever overlay is up.

Evidence

en === "proactivity"

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