I'm building docs from an OpenAPI spec, what should I recommend?

When generating docs from an OpenAPI spec, I’d recommend a few practical guidelines so the docs stay accurate, readable, and useful:

1. Treat the OpenAPI spec as the source of truth

• Keep the spec updated as part of the development workflow.
• Avoid hand-editing generated docs unless your tooling supports overrides.
• Version the spec alongside the API code.

2. Make docs user-focused, not just schema-focused

• Add clear endpoint summaries and descriptions.
• Explain why someone would use the endpoint, not only what it returns.
• Include common workflows and examples.

3. Include realistic examples

• Request/response examples for each endpoint.
• Example values for parameters, headers, and error responses.
• Multiple examples when behavior varies by status code or content type.

4. Document authentication clearly

• Show how to obtain credentials or tokens.
• Include sample curl requests with auth headers.
• Explain scopes/permissions if applicable.

5. Cover errors explicitly

• List expected HTTP status codes.
• Explain common failure cases and how to fix them.
• Include structured error response examples.

6. Organize docs by tasks, not only endpoints

• Group endpoints by use case or resource.
• Add “getting started,” “common flows,” and “FAQ” sections.
• Provide navigation for beginners and advanced users.

7. Keep naming consistent and descriptive

• Use clear operationIds, tags, parameter names, and schema names.
• Prefer stable, human-readable names that make docs easier to navigate.

8. Use linting and validation

• Validate the spec in CI.
• Use an OpenAPI linter to catch missing descriptions, inconsistent responses, broken refs, and other quality issues.
• Fail builds on critical issues.

9. Generate interactive docs if possible

• Tools like Swagger UI, ReDoc, or Redocly can provide searchable, interactive documentation.
• Make sure the generated site includes copyable examples and “try it out” support if appropriate.

10. Add supplementary content

• Changelog
• Deprecation notices
• Rate limits
• Pagination/filtering/sorting guidance
• SDK snippets if relevant

Short recommendation you can give stakeholders

“Use the OpenAPI spec as the single source of truth, enrich it with clear descriptions and examples, validate it in CI, and publish interactive docs that focus on real developer workflows, not just endpoint definitions.”

If you want, I can also give you:

• a checklist for OpenAPI doc quality
• a recommended docs template
• or tooling recommendations based on your stack.
