OpenAPI 3.1 specification, schema design, code generation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OpenAPI Specification Patterns > **Quick Guide:** Use OpenAPI 3.1 for API contracts. 3.1 is a superset of JSON Schema Draft 2020-12 -- use `type: ["string", "null"]` instead of `nullable: true`. Define all reusable schemas in `components/schemas` and reference with `$ref`. Always include `operationId` on every operation (it becomes the client method name). Use `openapi-typescript` to generate zero-runtime TypeScript types and `openapi-fetch` for a 6kb type-safe fetch client. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST use OpenAPI 3.1 syntax -- `type: ["string", "null"]` NOT the 3.0 `nullable: true` keyword)** **(You MUST define reusable schemas in `components/schemas` and reference with `$ref` -- NO inline schema duplication)** **(You MUST include `operationId` on every path operation -- it becomes the generated client method name)** **(You MUST use `openapi-typescript` for type generation and import types with `import type` -- types are zero-runtime)** </critical_requirements> --- …

How to install
mdr add agents-inc/skills/api-specs-openapi@sha256:43fba8824350d437The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
