Workflow Tracking

Each workflow has:

  • Pre-conditions check
  • Step-by-step execution
  • Progress indicators
  • Rollback capabilities
  • Success metrics
  • Celebration moments
  • Next workflow suggestions

API-Facilitated Actions

The system can automatically:

  1. Financial Moves: Transfer funds, adjust contributions, set up rules
  2. External Integrations: Calendar blocks, reminder systems, document requests
  3. Monitoring Setup: Alerts, thresholds, review schedules
  4. Social Features: Share sanitized insights, find accountability partners
  5. Learning Paths: Queue relevant education, track progress

This creates a complete ecosystem where simulation insights immediately translate into executable improvements in the user's financial life.
