openapi-spec-generation SKILL.md skillA
openapi-spec-generation from wshobson/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wshobson/agents/openapi-spec-generation@git:20260522.be57c0bPins git:20260522.be57c0b in mdr.lock. Pin the fingerprint instead.

Generate and maintain OpenAPI 3.1 specifications from code, design-first specs, and validation patterns. Use when creating API documentation, generating SDKs, or ensuring API contract compliance.
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 Spec Generation
Comprehensive patterns for creating, maintaining, and validating OpenAPI 3.1 specifications for RESTful APIs.
## When to Use This Skill
- Creating API documentation from scratch
- Generating OpenAPI specs from existing code
- Designing API contracts (design-first approach)
- Validating API implementations against specs
- Generating client SDKs from specs
- Setting up API documentation portals
## Core Concepts
### 1. OpenAPI 3.1 Structure
```yaml
openapi: 3.1.0
info:
title: API Title
version: 1.0.0
servers:
- url: https://api.example.com/v1
paths:
/resources:
get: ...
components:
schemas: ...
securitySchemes: ...
```
### 2. Design Approaches
| Approach | Description | Best For |
| ---------------- | ---------------------------- | ------------------- |
| **Design-First** | Write spec before code | New APIs, contracts |
| **Code-First** | Generate spec from code | Existing APIs |
| **Hybrid** | Annotate code, generate spec | Evolving APIs |

How to install
mdr add wshobson/agents/openapi-spec-generation@sha256:8071736973f8a99cThe line at the top of this page pins the label git:20260522.be57c0b, 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.
