Unclear It is not clear what this check allows or blocks.

What

Claude Code adds a check that allows an item in either of two ways:

  • it passes an existing built-in test
  • Claude Code is connected directly to Anthropic's own API, and the item appears on a list sent by the server

When the server sends no list, only the built-in test applies.

Why

Anthropic can extend what this check allows for direct API users without a new release.
