form

Generate a validated form for $ARGUMENTS.

Steps

1. Check existing components — call get_components and look for existing form field primitives before creating new ones

2. Define the zod schema — write a z.object() schema in a dedicated <feature>.schema.ts file; derive the TypeScript type with z.infer

3. Wire the form — use useForm<FormValues> with zodResolver(schema) and explicit defaultValues for every field

4. Render with Controller — always use Controller (never register) for React Native compatibility; use project form field components or Tamagui Input + Label as fallback

5. Handle submission — handleSubmit(onSubmit) where onSubmit receives the fully-typed payload; use setError("root", ...) for server-returned errors

6. i18n — every label, placeholder, and error string wrapped with Trans / t`…`

7. Type-check — run tsc --noEmit and fix all errors before reporting done

Canonical output shape

// <feature>.schema.ts
import { z } from "zod";
export const mySchema = z.object({ ... });
export type MyFormValues = z.infer<typeof mySchema>;

// <Feature>Form.tsx
import { zodResolver } from "@hookform/resolvers/zod";
import { useForm, Controller } from "react-hook-form";
import { mySchema, type MyFormValues } from "./<feature>.schema";

export function MyForm({ onSuccess }: { onSuccess: () => void }) {
  const { t } = useLingui();
  const { control, handleSubmit, formState: { errors, isSubmitting } } = useForm<MyFormValues>({
    resolver: zodResolver(mySchema),
    defaultValues: { ... },
  });

  const onSubmit = async (data: MyFormValues) => { ... };

  return (
    <YStack gap="$md">
      <Controller
        control={control}
        name="fieldName"
        render={({ field }) => (
          <FormField label={t`Label`} error={errors.fieldName} {...field} />
        )}
      />
      <Button onPress={handleSubmit(onSubmit)} disabled={isSubmitting}>
        <Trans>Submit</Trans>
      </Button>
    </YStack>
  );
}

Rules

• Schema in a separate file when reused across screens
• defaultValues must cover every field — no uncontrolled → controlled warnings
• Never use .optional() to silence TS errors — fix the type at the source
• Never suppress react-hooks/exhaustive-deps — fix the dependency
• Run tsc --noEmit after generation; zero errors before reporting done
