Spec-first REST development in Go with OpenAPI: generating server interfaces and clients with oapi-codegen, request validation middleware, RFC 9457 error bodies, contract testing, and detecting breaking API changes. Use when the API has or should have an OpenAPI document, when wiring code generation into the build, or when a hand-written handler has drifted from its published contract. Trigger examples: "OpenAPI", "swagger spec", "oapi-codegen", "generate a client from the spec", "validate requests against the schema", "breaking API change". Not for: handler structure and shutdown (go-api-design), gRPC and protobuf (go-grpc), GraphQL schemas and resolvers (go-graphql).

From the source SKILL.md

The spec is the source of truth. Types, routes, and clients are generated from it — never hand-written alongside it, because two hand-maintained copies of a contract diverge within one sprint.

What this skill does

Go Openapi is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/go-openapi/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the API has or should have an OpenAPI document, when wiring code generation into the build, or when a hand-written handler has drifted from its published contract. Trigger examples: "OpenAPI", "swagger spec", "oapi-codegen", "generate a client from the spec", "validate requests against the schema", "breaking API change".
