# Angular CVA setDisabledState v15
## Purpose
Use this skill to review custom `ControlValueAccessor` implementations for Angular 15 `setDisabledState` behavior.
## When to Use
- The project contains custom CVAs.
- Form controls have custom disabled behavior.
## Do
- Check `writeValue`, `registerOnChange`, `registerOnTouched`, and `setDisabledState`.
- Confirm disabled state flows match the component behavior.
## Do Not
- Do not ignore custom CVAs in critical forms.
- Do not rely on undocumented disabled behavior.
## Review Checklist
- [ ] CVA inventory is complete.
- [ ] setDisabledState is implemented or explicitly not required.
- [ ] Disabled behavior is tested or documented.
## Expected Output
1. CVA inventory.
2. setDisabledState coverage.
3. Risk or required fix.
