What's Wrong?

Environment:

• Claude Code v2.1.12
• macOS
• Claude Max subscription
• GitHub connected and repo authorized (private repo)

Steps to reproduce:

1. Install Claude Code CLI
2. Run claude in repo directory
3. Run /login - succeeds
4. Run /remote-env - shows "No remote environments available"
5. Run claude --remote "explore the repo" - returns "Error: Unable to create remote session"
6. Visit claude.ai/code - no option to create cloud environment
7. GitHub app installed and repo authorized

Expected:
Cloud environment should be created automatically, or there should be a way to create one via CLI or web UI.

Actual:
No cloud environment exists and no way to create one. Blocks Slack integration.

Workaround:
None found.

What Should Happen?

Cloud environment should be created automatically when GitHub is connected, or there should be a clear way to create one via CLI or web UI. The /remote-env command should show available environments and allow creating new ones.
