What

The Agent SDK lets other programs run Claude Code. When Claude Code needs a fresh sign-in token, it sends the host program an oauth_token_refresh request. That request now includes token_state:

  • not_refused: the token is only stale.
  • refused: the token was rejected.

Before, the request did not say which.

Why

A host program can now tell a token that simply needs renewing from one that was turned down, and respond to each differently.
