[Bug]: Unable to use Claude Code models with apiKeyHelper setting

Bug type

Incorrect behavior or output

Summary

Symptom: "Not logged in" error when using Claude Code models in pi with Vertex AI / apiKeyHelper auth

Root cause: buildSdkOptions in claude-code-cli/stream-adapter.js sets settingSources: ["project"], which excludes ~/.claude/settings.json where apiKeyHelper and Vertex config are defined

Fix: Change to settingSources: ["user", "project"] so user-level auth settings are respected

Steps to reproduce

1. Use "apiKeyHelper" property in .claude/settings.json
2. Switch model to claude model
3. Send message
4. See error: "Not logged in - Please run /login"
