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.

Credentials and storage handles passed explicitly instead of read from ambient state

Under the hood
Useful1 Signal2
Internals

Credentials and storage are passed explicitly rather than read from ambient state.

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 v2.1.246: not a boolean we can read

Read once, for one account on one subscription tier, against v2.1.246. It isn't a statement about your account. What a flag value here can and cannot tell you

What

API key verification, model-config fetching, the network-permission classifier and several resume and print helpers now take credentials and a storage handle as arguments. Worker startup and the Chrome MCP server prime credentials, cached managed settings and a stored login copy before running.

Details
  • On Windows, the credential-manager storage backend is selected only when the cached remote flag tengu_windows_credman is true, so it stays off unless that flag is set.
Evidence

api_key_verify

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