Companion Skill Policy

When sphere-layout-feature-workflow is available in the current session, use it together with this skill.

Collaboration rules:

1. Let sphere-layout-feature-workflow drive framework-native feature assembly (middleware, auth, errors, routing, wiring flow).
2. Let proto-service-skeleton focus on per-service file generation/completion from *ServiceHTTPServer.
3. Prefer shared framework capabilities over custom implementation.
4. Avoid implementing duplicate functionality when an equivalent capability already exists in this repository or the Sphere stack.
