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.

Feature flag
tengu_herring_clock 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.

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 v2.1.210. It isn't a statement about your account. What a flag value here can and cannot tell you

The memory sync architecture change removes the following:

  • The ANTHROPIC_BEDROCK_MANTLE_API_KEY environment variable is no longer recognised.
  • The old /api/claude_code/memory and /api/claude_code/team_memory endpoints are no longer contacted by the client. If your infrastructure blocks outbound access to the new /v1/code/local/memory/mounts and /v1/code/local/memory/credential endpoints, org memory will not function. The CLAUDE_CODE_DISABLE_ORG_MEMORY=1 environment variable can disable the feature entirely.
  • The tengu_herring_clock feature flag (which gated the old personal memory sync) has been removed along with the sync implementation it guarded.
