Frontend To Backend Requirements

What it does

This skill bridges the gap between UI design and server logic by analyzing frontend code to generate precise backend requirements. It extracts data models, API endpoints, and validation rules directly from your existing HTML, CSS, or JavaScript files to ensure full-stack consistency.

When to use it

• You have a finished frontend prototype but lack a defined database schema or API contract.
• Your team needs to align backend development with specific UI interaction patterns before writing server code.
• You want to automate the documentation of data structures and state management flows from your current interface.
• You are refactoring an application and need to verify that new frontend features require corresponding backend changes.

Key capabilities

• Parses frontend source files to identify necessary data entities and relationships.
• Generates structured API endpoint definitions based on user actions and form inputs.
• Outputs validation rules and error handling strategies derived from UI constraints.
• Creates a clear specification document for backend engineers or AI agents to implement the logic layer.

Example prompts

• "Analyze this React component file and list all required database tables, their fields, and relationships."
• "Generate a REST API specification including endpoints and request payloads based on these HTML forms."
• "Extract validation rules from this JavaScript code and suggest corresponding backend error responses."

Tips & gotchas

Ensure your frontend code includes clear comments or naming conventions for data entities to improve extraction accuracy. This skill focuses on requirements generation; it does not automatically write the backend implementation code itself.
