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.

Claude Code v2.1.227

Feature-flag machinery rebuilt as a class with a real dispose path

Under the hood
Useful2 Signal2
Internals

Feature-flag handling now cleans up properly, restoring the original fetch when disposed.

Feature flag
tengu_gb_eval_authed_enable Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.227: not a boolean we can read

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 v2.1.227. It isn't a statement about your account. What a flag value here can and cannot tell you

What

Client creation, exposure logging, remote evaluation, disk sync and the periodic refresh loop moved from module-level globals into one class with injected dependencies behind a lazy singleton. Disposing now restores the SDK's own fetch function instead of leaving the patched wrapper installed, and a disposed instance stops creating clients or refreshing.

Details
  • The authenticated evaluation endpoint is still decided per call by tengu_gb_eval_authed_enable, whose in-source fallback is false; nothing in this build sets it, so the real value comes from remote config.
Evidence

tengu_gb_eval_authed_enable

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