One-Click API Key Setup — full flow

CLI initiates → verified consent → key issued → CLI resumes automatically. Four frames, read left-right, top-bottom.

1 Claude Code initiates

Claude CodeCLI detects no ANTHROPIC_API_KEY; user presses ⏎ to open the verified browser handoff.

2 Verified consent

platform.claude.com/setupUser authenticates to Anthropic; the verified-tool slug drives the trust badge.

3 Key issued

platform.claude.com/setupOne click sends the key directly to frontend/.env — nothing to paste.

4 Claude Code resumes

Claude CodeCLI auto-detects the key, calls /v1/messages, writes the lesson file, and reports back.
