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.

Frame publish context can no longer be turned on

Useful1 Signal3
Remote Config

Frame publish context is now permanently off and no server setting can enable it.

Feature flag
tengu_frame_publish_context Gate removed from the code

This release deleted the gate from the code while it was still reading on for the account this site reads, so the code path no longer asks a flag before running.

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

What

This path was previously behind the tengu_frame_publish_context remote flag, off unless Anthropic's config enabled it. The flag lookup is gone and the check now returns false unconditionally; the flag name no longer appears anywhere in the build, so no server value can switch it on.

Evidence

return K("tengu_frame_publish_context", !1);

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