Consider deprecating old hooks API

**Problem**
When working with utils, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The title concerns the old hooks API, while the body asks for clearer errors in utils. Start by locating the hooks and utils entry points, then clarify which change is intended and review any existing error-handling behavior. Done requires an agreed deprecation scope or a precise error-message target with verifiable expectations.
