Consider deprecating old types API

**Problem**
When working with hooks, 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 issue names hooks and an old types API but does not identify files, tests, or an entry point. Start by locating those references in the repository, then clarify the deprecation scope, replacement API, error-message expectations, and tests that would define completion.
