shadcn-agents-form-validator

shadcn ui forms submit undefined values when react-hook-form and zod disagree on schema paths, missing defaultValues, or broken zodResolver wiring. Auditing the JSX Form tree against the zod schema identifies exact field name mismatches causing empty submissions.

To fix validation not triggering, verify zodResolver is correctly wired to useForm and that FormField names exactly match zod schema paths. An eight-point integration audit detects missing handleSubmit wrapping or Controller bindings that silently break validation.

Use Controller vs register based on whether the shadcn ui component is controlled, such as Select, Checkbox, Switch, or RadioGroup. Checking Controller-vs-register correctness prevents uncontrolled-to-controlled warnings and ensures form values properly bind to react-hook-form.

Your react-hook-form setup requires defaultValues for every zod schema field to prevent undefined submission values. Checking defaultValues completeness ensures the resolver initializes all form paths correctly and prevents silent validation skips.

The best way to audit AI-generated react-hook-form and zod code is parsing the JSX Form tree and zod schema to run a deterministic eight-point checklist. This produces a structured pass/fail verdict with canonical fixes for missing FormMessage or duplicated FormProvider contexts.
