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.

Claude Code v2.1.224

Artifact tool now explains exactly which credential is blocking it

You'll notice
Useful4 Signal2
Artifacts

The artifact tool now names the exact credential blocking you, with a fix for each.

ANTHROPIC_API_KEYapiKeyHelper
What

When you are not logged in, both the input check and the tool call stop immediately and name the credential source that is standing in the way: the ANTHROPIC_API_KEY environment variable, the apiKeyHelper setting, a token file descriptor, or a Unix socket, each with its own fix.

Details
  • for the environment variable the advice is to unset it, or run /logout and decline the API key approval before logging back in
Evidence

Unset the ANTHROPIC_API_KEY environment variable, or claude /logout then say "No" to the API key approval before login.

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