CLAUDE_CODE_OAUTH_TOKEN silently deletes macOS Keychain credentials on exit
증상
Setting CLAUDE_CODE_OAUTH_TOKEN as an environment variable causes the CLI to silently delete the macOS Keychain credential entry (“Claude Code-credentials”) on process exit. This breaks authentication for all other Claude Code sessions (VS Code extension, other terminals).
원인
Environment variable, configuration file, or initialization parameter missing, malformed, or incorrectly scoped.
해결법
We built a wrapper script that:
- Extracts the token from
~/.claude/.credentials.json(not Keychain) - Passes
CLAUDE_CODE_OAUTH_TOKENonly to the child process - Restores the Keychain entry after batch completion if deleted
```bash #!/bin/bash
