Worked on the RedHatProductSecurity/osidb repository to enhance the available-flaws API endpoint, focusing on aligning its behavior with official specifications. Addressed a key issue by updating the endpoint to return a 204 response for non-existent flaws, rather than a 404, ensuring that CVEs not yet present in the database are handled according to spec and improving compatibility with public CVE workflows. Utilized Python and YAML to implement and document the backend change, emphasizing precise API semantics and clear commit messaging. This targeted fix improved downstream integration reliability and demonstrated careful attention to both technical detail and repository standards.
