It all started with a task to rotate secrets for a service at work. I followed the AWS documentation and implemented a lambda function using one of their templates. It worked, but I was curious about how it worked since there was a condition in code which would never be met.

I've been building APIs using an Spec/API-first development approach with oapi-codegen and Gin for almost a year. I needed to make some of my APIs available only in the staging environment, controlled by feature flags. Since OpenAPI doesn't directly support feature flags, I created a solution using OpenAPI extensions and a custom Gin middleware that checks flags at runtime.
