To generate frontend API contracts, this Skill analyzes backend Models, server scripts, and HTTP interfaces to extract request and response shapes, capturing field names, data types, and stability classifications for integration.

A frontend-ready data contract is a machine-readable schema derived from backend entrypoints that includes field names, data types, units, default values, error semantics, and stability notes to drive UI integration and testing.

You can extract error semantics and default values by applying contract derivation to your backend APIs, which formalizes the surface of HTTP interfaces and Models into a consistent, documented data contract.

Yes, you can generate representative mock payloads and integration notes for both single endpoints and multi-endpoint workflows by applying contract derivation against your backend entrypoints and script outputs.

This works across repository HTTP interfaces, Models, and server scripts regardless of the framework, extracting request and response shapes to produce a consistent frontend-consumable spec.

The best way to document backend API field types and units is to extract and formalize the surface of backend entrypoints, producing a stable data contract that captures expected types, units, and error models.
