SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents discrepancies and hallucinations between the data provided by the backend API and what is displayed in the frontend user interface, ensuring data integrity and a consistent user experience.

Core Features & Use Cases

  • Data Contract Enforcement: Guarantees that every piece of data shown in the UI originates directly from the backend API.
  • Hallucination Prevention: Stops the UI from inventing or displaying data not present in the API response.
  • Use Case: When a new feature is developed, this skill ensures that any new data field displayed on the frontend is explicitly returned by the corresponding backend API endpoint, preventing "phantom" data from appearing to users.

Quick Start

Verify that all UI elements accurately reflect the data returned by the /api/users endpoint.

FAQPage Schema
How do I enforce a one-to-one mapping between backend API data and frontend UI elements?▼

You enforce a one-to-one mapping by validating UI components against API contracts to ensure all displayed fields have a direct, verifiable source in backend responses. This prevents unverified or fabricated data from rendering in the user interface.

What is the best way to prevent frontend UI hallucinations of data not present in backend API responses?▼

The best way to prevent frontend UI hallucinations is to implement contract validation that blocks merges on any detected misalignment. This stops the UI from inventing or displaying phantom data fields not explicitly returned by the backend API.

How do I validate new UI components against an API contract during feature development?▼

You validate new UI components by checking that every newly displayed data field originates directly from the corresponding backend API endpoint. This ensures data integrity and a consistent user experience by preventing unverified data introduction.

Can I block code merges automatically when frontend data structures do not match backend responses?▼

Yes, you can block code merges automatically when frontend data structures do not match backend responses. The validation process detects any misalignment between the UI and the API contract and prevents the merge from completing.

Why does my frontend display data fields that are missing from the backend API endpoint?▼

Your frontend displays missing data fields because the UI lacks strict enforcement of backend data structures, allowing fabricated or phantom data to render. Validating UI components against the API contract ensures all displayed fields have a verifiable backend source.
