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.

More cloud token failures recognised as expired credentials

You'll notice
Useful3 Signal2
Auth

More Bedrock and Vertex token failures now say your credentials expired so you can re-authenticate.

What

Three more provider error strings are now matched by the check that classifies a failure as expired or invalid credentials, so Bedrock and Vertex style token and API key failures surface as an auth expiry you can re-authenticate from, instead of a generic error.

Evidence

Bearer Token has expired

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