[yize]

Summary

• Add --check-only parameter to check login status without triggering login flow
• Add auto-select org logic: if only 1 organization detected, automatically select and complete login
• Add can_auto_use field for AI Agent to determine if login is available
• Add human-readable message output

Changes

• Modified skills/yida-login/scripts/login-interactive.py:
  • Added check_login_only() function
  • Added --check-only CLI argument support
  • Modified stage2_get_org_list() to auto-select when only 1 org

Usage

Check login status

python3 login-interactive.py --check-only

Returns:

{
  "status": "ok",
  "can_auto_use": true,
  "csrf_token": "xxx",
  "corp_id": "dingxxx",
  "user_id": "195xxx",
  "base_url": "https://ding.aliwork.com",
  "message": "✅ 已有有效登录态，可直接使用"
}

Auto-select org

When user scans QR code and only 1 organization is detected, the login flow automatically completes without requiring user to reply with org number.

User Experience Improvement

Scenario	Before	After
Already logged in	AI asks to continue	Use directly (no interaction)
1 org detected	User replies with number	Auto-select
Multiple orgs	User replies with number	Still requires selection
