+# Summary
+
+Expand the warning information of validator verification to provide clearer error prompts.
+
+# Basic example
+
+```vue
+<script setup>
+defineProps({
+  num: {
+    type: Number,
+    extendValidator(name, value, props, warn) {
+			if (typeof value !== 'number') {
+				warn(`[Custom Component]: Invalid prop: custom validator check failed for prop "${name}", expected type number, but got ${typeof value}`)
+			} else (!Number.isInteger(value)) {
+				warn(`[Custom Component]: Invalid prop: custom validator check failed for prop "${name}", expected an integer.`)
+			}
+    }
+  }
+})
+</script>
+```
+
+# Motivation
+
+In custom components, we usually validate many props for a better user experience. Currently, the validator function will only return true or false. If it is false, it means that the validation has failed and a warning message will be thrown inside vue.
+
+However, the warning message only indicates that a prop check failed, but users cannot customize and expand more specific error descriptions.
+
+# Detailed design
+
+In order not to affect the original users, it may be a good idea to add a new function to give users more customization space.
+
+refer #Basic example
+
+# Drawbacks
+
+In most cases, the current validator function will suffice. (This proposal is merely to optimize the development experience based on the original one.)
+
+# Alternatives
+
+Add new parameters based on the original validator and make different processing according to different parameters.
+
+# Adoption strategy
+
+
+# Unresolved questions
