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.

Clearer API Authentication Error

What

When the bundled Anthropic API client cannot resolve credentials, the error now says it expects either apiKey or authToken, instead of listing removed credential/profile/config options.

Usage
ANTHROPIC_API_KEY=... claude
Details
  • This makes auth failures less misleading for users who hit lower-level API-client errors.
  • The new message points users toward API key or bearer-token authentication.
  • The previous message referenced credentials, config, and profile; those are no longer listed in the failure text.
Evidence

Authentication validation message changed (search for "Could not resolve authentication method. Expected either apiKey or authToken to be set").

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