Buf argues AI agents need Protobuf contracts

The author argues that AI agents need deterministic contracts like Protobuf and schema validation tools to prevent breaking production APIs when making code modifications. Without hard constraints and checks such as buf breaking and buf lint, agents can inadvertently alter schemas in ways that break dependent client services even when unit tests pass. Implementing server-side governance through the Buf Schema Registry provides organizations with review workflows and policies to safely manage schema changes at scale. Open article →
