[BUG] Can't authenticate in the CLI because the browser automatically redirects

[kosmos]

Environment

• Platform (select one):
  • Anthropic API
  • AWS Bedrock
  • Google Vertex AI
  • Other:
• Claude CLI version: 1.0.70 (Claude Code)
• Operating System: MacOS Version 15.5 (24F74)
• Terminal: Ghosty

Bug Description

I can't authenticate in the CLI because the browser automatically redirects from the authentication page to the chat page. I don't have time to click the "Authorize" button.

Steps to Reproduce

1. Copy login link from CLI.
2. Past login link to browser.

Expected Behavior

I expect to be able to click the "Authorize" button on the authentication form.

Actual Behavior

Instead, I am immediately redirected to the chat page as soon as the form is displayed, without having a chance to click the button.

Additional Context

In the CLI, I see the following error:

OAuth error: Invalid code. Please make sure the full code was copied

[kosmos]

The bug was fixed by fully completing the onboarding process.
Before the user finishes onboarding, any attempt to authenticate in Claude Code redirects them back to the onboarding page, making it impossible to obtain the code.
