Improve hooks performance

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

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

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

No files, tests, or entry points are named. Start by locating the validation and hook error-handling paths, then determine how the performance concern relates to the request for more descriptive messages. Done should be defined by agreed scope, measurable hook behavior, and coverage for the updated error messages.
