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.

Grove, voice, design and bridge calls switch to explicit credentials behind a startup switch

Under the hood
Useful1 Signal3
Auth

Several internal services now receive login credentials directly instead of grabbing whatever token is lying around.

Feature flag
tengu_windows_credman Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.239: not a boolean we can read

Read once, for one account on one subscription tier, against v2.1.239. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A build-wide switch, pinned once at startup, decides whether these call sites pass an explicit credentials object or fall back to reading ambient OAuth tokens. Affected: Grove settings and notice, voice stream, design session auth, bridge session fetch and patch, peer listing, tips prewarm.

Details
  • Grove's cached fetchers now key on "account" and "config" instead of sharing one entry.
  • Startup also primes the credential-storage decision from a cached feature flag and loads remote settings earlier.
  • Related telemetry name: tengu_windows_credman.
Evidence
