The following comment was made by an LLM, it may be inaccurate: Based on my search, I found one potentially related PR: Related PR:
The current PR #20080 is the only one directly addressing Claude Code OAuth credentials detection and Anthropic authentication in the way described. PR #18674 appears to handle OAuth plugin vendoring and PKCE security, which could be relevant context for understanding the overall OAuth implementation approach. |

Issue for this PR
Closes #20079
Type of change
What does this PR do?
Adds support for authenticating with Anthropic using Claude Code OAuth credentials (
~/.claude/.credentials.json) when noANTHROPIC_API_KEYis set.Two files changed:
claude-code-credential.ts— reads the credential file, caches the token (5 min TTL), checks expiryprovider.ts— the Anthropic custom loader detects the OAuth token, passes it viaauthTokentocreateAnthropic(), adds OAuth beta headers, and injects the billing header + metadata in the fetch wrapperAPI key always takes precedence. No behavior change for users without Claude Code credentials.
