description	Use when changing NativeLink JSON5 configuration, deployment examples, protobuf/service protocol surfaces, or compatibility-sensitive config behavior.

NativeLink Config And Protocol Changes

Use this skill when a task touches nativelink-config, JSON5 examples, deployment config, protobuf definitions, generated protocol code, or service APIs.

Config Changes

NativeLink config changes usually require more than editing one struct.

Check:

• nativelink-config/ for config structs and serialization behavior.
• nativelink-config/examples/ for JSON5 examples.
• deployment-examples/, deploy/, kubernetes/, and templates/ for user-facing config samples.
• Tests that load example config files.

Preserve compatibility where practical:

• Add default values when old config files should continue to load.
• Avoid renaming public fields without aliases or migration notes.
• Keep comments in JSON5 examples accurate and actionable.
• Treat config validation errors as user-facing diagnostics.

Protocol Changes

For service or proto work, inspect both the generated API surface and the implementation layer:

• nativelink-proto/ for protobuf definitions and generated interfaces.
• nativelink-service/ for REAPI, bytestream, BEP, worker API, and health service behavior.
• nativelink-util/ for shared digest/proto conversion helpers.

Don't manually edit generated code unless the repository's generation workflow requires checked-in generated changes.

Testing

Start focused:

bazel test //nativelink-config/...
bazel test //nativelink-service/...

Then broaden when the change crosses service boundaries:

bazel build //:nativelink
bazel test //...

For docs or examples:

bazel build docs
bazel build nativelink-config:docs
bazel test doctests

Review Checklist

• Existing config files still load.
• New fields have defaults where needed.
• Error messages identify the invalid field or service behavior.
• Examples and templates match the implementation.
• Protocol changes are reflected in service tests and consumers.
