  API Evangelist from the provider's own Protobuf contract and documentation.

      Saved VERBATIM from Buf's official Claude Code plugin marketplace. Buf ships it as
      the `protobuf` skill inside the `protobuf` plugin, together with a bundled
      `buf lsp serve` LSP server and nine reference documents (best practices,
      protovalidate, buf toolchain, migration, troubleshooting, review checklist).
      Only the SKILL.md is mirrored here; the references and assets stay upstream.
    summary: >-
      Proto design, buf CLI usage, gRPC/Connect service definition, protovalidate
      constraints, schema evolution, and lint/breaking-change troubleshooting.

    note: >-
      Written by API Evangelist. Every RPC named in it was read out of the .proto files in
      grpc/; no method name is invented. The reversal table and the idempotency claim are
      derived from `option idempotency_level` declarations in the same contract.
    summary: >-
      How an agent calls the BSR over Connect/gRPC: URL shape, bearer auth, resolving a
      module reference, paging, fetching descriptors, atomic batch writes and their
      reversals, and Connect error handling.
