Wouter van der Linde enhanced the neuvector/neuvector repository by improving the Admission Control Rules Test Endpoint, focusing on usability and testability for QA and security teams. He updated the API documentation to clarify content types and provided a detailed YAML payload example, making it easier for users to understand and interact with the endpoint. By adjusting access control, he enabled read-only users to test policies, broadening test coverage and reducing bottlenecks in policy verification. His work leveraged Go and YAML, applying skills in API development, backend engineering, and access control to deliver a more efficient and accessible policy testing workflow.
