SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill solves the problem of API drift by ensuring that Go server implementations, client code, and request validation logic are strictly generated from a single source-of-truth OpenAPI 3.1 contract.

Core Features & Use Cases

  • Strict Contract Enforcement: Generates typed server interfaces and client code that fail to compile if the implementation deviates from the API spec.
  • Runtime Validation: Automatically wires kin-openapi middleware to enforce schema constraints like enums, formats, and required fields before requests reach your handlers.
  • Advanced Pattern Support: Provides standardized Go representations for complex API patterns including Field Masks, Long-Running Operations, and Resource Revisions (ETags).

Quick Start

Use the go-openapi-codegen skill to generate the server interface and client models from the api/openapi.yaml contract file.

FAQPage Schema
How do I generate Go server interfaces from an OpenAPI 3.1 spec?

Generating type-safe Go server interfaces from OpenAPI 3.1 specifications ensures implementation code remains strictly synchronized with your API contract, preventing API drift by failing to compile if the server deviates from the spec.

How does contract-first API development prevent API drift in Go?

Contract-first API development prevents drift by generating Go server interfaces, clients, and validation logic directly from a single OpenAPI 3.1 source-of-truth, ensuring implementation code remains strictly synchronized with API definitions.

Can I automatically enforce OpenAPI schema validation in Go request handlers?

Yes, runtime schema enforcement is achieved by automatically wiring kin-openapi middleware to validate schema constraints like enums, formats, and required fields before requests reach your Go handlers.

Does Go codegen from OpenAPI 3.1 support complex API patterns like Field Masks and ETags?

Yes, generating code from OpenAPI 3.1 provides standardized Go representations for complex API patterns including Field Masks, Long-Running Operations, and Resource Revisions (ETags) directly from the contract.

What is the best way to keep Go client code synchronized with an OpenAPI contract?

The best way to keep Go client code synchronized with an OpenAPI contract is through contract-first codegen, which generates type-safe clients from a single OpenAPI 3.1 source-of-truth to ensure strict type-safety and consistent versioning across service boundaries.

Do I need to manually validate request formats if I generate Go code from OpenAPI?

No, generating Go code from OpenAPI automatically wires kin-openapi middleware to enforce schema constraints like formats, enums, and required fields before requests reach your handlers, eliminating the need for manual request validation.
