Implementation Checklist
- Define request and response schemas for every public operation.
- Include operation IDs, auth requirements, and error payload examples.
- Publish OpenAPI in both /.well-known and canonical API reference locations.
- Ensure content-type consistency across retries and mirrors.
- Add versioning policy and deprecation guidance in docs.
Fast Wins (This Week)
Validate schema with CI before deploy.
Add deterministic examples for top 10 endpoints.
Use stable enums and avoid undocumented free-form objects.
FAQ
Why are OpenAPI examples important for AI agents?
Examples reduce ambiguity and help agents generate valid requests faster, which improves completion and lowers retry loops.
Should we expose internal endpoints in OpenAPI?
No. Keep public OpenAPI focused on supported external operations with explicit auth and error semantics.
