4545In bare mode, Claude Code never reads OAuth credentials or the system keychain. For the Anthropic API, set `ANTHROPIC_API_KEY` in the environment, with a key created in the [Claude Console](https://platform.claude.com), or supply an `apiKeyHelper` in the `--settings` JSON. Amazon Bedrock, Google Cloud's Agent Platform, and Microsoft Foundry continue to read their own provider credentials as usual.

Don't use bare mode for a run that needs them.
