During April 2025, Jeff Jeffries developed a Protobuf breaking changes detection system for the netboxlabs/diode repository. He implemented a Makefile task that runs buf breaking against proto definitions, enabling developers to identify breaking changes locally before code review. To further automate this process, Jeff added a GitHub Actions workflow using buf-action, which validates proposed changes against the develop branch in CI, ensuring API compatibility is maintained prior to merges. His work leveraged Makefile, YAML, and CI/CD practices, resulting in improved API stability, faster feedback cycles, and stronger governance over protocol changes, though the scope was limited to a single feature.
