buf-cli-lint-breaking-build

Overview

Wraps three buf CLI commands - build, lint, breaking - as the proto-PR gate, per buf.build/docs/cli/quickstart/. Pairs with protobuf-versioning-strategy-reference for the catalog of what counts as breaking and why.

When to use

• Adding buf as the proto lint + breaking-change gate on a new repo.
• A PR changes .proto files - need to gate the merge.
• Investigating a buf breaking failure - what rule fired?
• Configuring buf for a monorepo with multiple proto modules.
