vue
Vue 3 Composition API, script setup macros, reactivity system, and built-in components. Use when writing Vue SFCs, defineProps/defineEmits/defineModel, watchers, or using Transition/Teleport/Suspense/KeepAlive.
Best use case
vue is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Vue 3 Composition API, script setup macros, reactivity system, and built-in components. Use when writing Vue SFCs, defineProps/defineEmits/defineModel, watchers, or using Transition/Teleport/Suspense/KeepAlive.
Teams using vue should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Vue
> Based on Vue 3.5. Always use Composition API with `<script setup lang="ts">`.
## Preferences
- Prefer TypeScript over JavaScript
- Prefer `<script setup lang="ts">` over `<script>`
- For performance, prefer `shallowRef` over `ref` if deep reactivity is not needed
- Always use Composition API over Options API
- Discourage using Reactive Props Destructure

## Quick Reference
### Component Template
```vue
<script setup lang="ts">
import { ref, computed, watch, onMounted } from 'vue'
const props = defineProps<{
title: string
count?: number
}>()
const emit = defineEmits<{
update: [value: string]
}>()
const model = defineModel<string>()
const doubled = computed(() => (props.count ?? 0) * 2)
watch(() => props.title, (newVal) => {
console.log('Title changed:', newVal)
})
onMounted(() => {
console.log('Component mounted')
})
</script>
<template>
<div>{{ title }} - {{ doubled }}</div>
</template>
```
### Key Imports
```ts
// Reactivity
import { ref, shallowRef, computed, reactive, readonly, toRef, toRefs, toValue } from 'vue'
// Watchers
import { watch, watchEffect, watchPostEffect, onWatcherCleanup } from 'vue'
// Lifecycle
import { onMounted, onUpdated, onUnmounted, onBeforeMount, onBeforeUpdate, onBeforeUnmount } from 'vue'
// Utilities
import { nextTick, defineComponent, defineAsyncComponent } from 'vue'

use-zod
Answer questions about the Zod schema validation library and help build schemas, parsers, refinements, transforms, codecs, and error formatters. Use when developers: (1) ask about Zod APIs like `z.object`, `z.string`, `z.array`, `z.union`, `z.discriminatedUnion`, `parse`, `safeParse`, `z.infer`; (2) define request/response/form schemas in TypeScript; (3) handle `ZodError` or customize error messages; (4) migrate between Zod v3 and v4 (entry-point split, `formatError` → `treeifyError`/`prettifyError`, unified `error` param replacing `message`/`errorMap`). Triggers on: "zod", "z.object", "z.string", "z.array", "z.union", "z.infer", "z.input", "z.output", "ZodError", "$ZodError", "safeParse", "parseAsync", "z.codec", "treeifyError", "prettifyError", "flattenError", "discriminatedUnion", "zod/v4", "zod/v3", "zod/mini", "z.coerce", "superRefine".
workflow
Creates durable, resumable workflows using Vercel's Workflow SDK. Use when building workflows that need to survive restarts, pause for external events, retry on failure, or coordinate multi-step operations over time. Triggers on mentions of "workflow", "durable functions", "resumable", "workflow sdk", "queue", "event", "push", "subscribe", or step-based orchestration.
wpds

wp-rest-api
Use when building, extending, or debugging WordPress REST API endpoints/routes: register_rest_route, WP_REST_Controller/controller classes, schema/argument validation, permission_callback/authentication, response shaping, register_rest_field/register_meta, or exposing CPTs/taxonomies via show_in_rest.
wp-project-triage
Use when you need a deterministic inspection of a WordPress repository (plugin/theme/block theme/WP core/Gutenberg/full site) including tooling/tests/version hints, and a structured JSON report to guide workflows and guardrails.

Use when developing WordPress plugins: architecture and hooks, activation/deactivation/uninstall, admin UI and Settings API, data storage, cron/tasks, security (nonces/capabilities/sanitization/escaping), and release packaging.
wp-playground
Use for WordPress Playground workflows: fast disposable WP instances in the browser or locally via @wp-playground/cli (server, run-blueprint, build-snapshot), auto-mounting plugins/themes, switching WP/PHP versions, blueprints, and debugging (Xdebug).
wp-phpstan
Use when configuring, running, or fixing PHPStan static analysis in WordPress projects (plugins/themes/sites): phpstan.neon setup, baselines, WordPress-specific typing, and handling third-party plugin classes.
wp-performance
Use when investigating or improving WordPress performance (backend-only agent): profiling and measurement (WP-CLI profile/doctor, Server-Timing, Query Monitor via REST headers), database/query optimization, autoloaded options, object caching, cron, HTTP API calls, and safe verification.
wp-block-development
Use when developing WordPress (Gutenberg) blocks: block.json metadata, register_block_type(_from_metadata), attributes/serialization, supports, dynamic rendering (render.php/render_callback), deprecations/migrations, viewScript vs viewScriptModule, and @wordpress/scripts/@wordpress/create-block build and test workflows.
wp-abilities-api
Use when working with the WordPress Abilities API (wp_register_ability, wp_register_ability_category, /wp-json/wp-abilities/v1/*, @wordpress/abilities) including defining abilities, categories, meta, REST exposure, and permissions checks for clients.
