Reference for querying the Atlas knowledge graph through its MCP tools — the SECONDARY enrichment/comparison layer that adds best-practice context to systems you have ALREADY scanned from your real sources (`az`, repos, dirs). Use when you need to look up nodes, edges, kinds, clusters, stats, or wiki pages in Atlas to compare against your real inventory. (atlas graph, query atlas, atlas mcp, search the graph, graph neighbors, atlas record, atlas kinds, enrichment layer)
Atlas turns your STATED NEED into a real systems atlas by SCANNING your actual sources (Azure via `az`, git repos, local dirs) and process/data mining them, THEN enriching against the Atlas knowledge graph. Use this skill when asked to inventory/map your real systems, scan your cloud + repos + directories, mine the real processes or data they contain, or collect their real constraints/gotchas. (atlas, scan my systems, inventory our azure account, map my repos, real systems atlas, process mining, data mining, collect nuances, system discovery)
assimilate-popular-workflows This skill should be used when the user asks to "find skills in the wild", "assimilate popular workflows", "discover SKILL.md files in repos", "research external skills", "find workflow patterns", "survey the skill landscape", "what skills exist out there", or wants to investigate public repositories for extractable processes, babysitter plugins, and reusable procedural insights. Searches GitHub for SKILL.md files, classifies repos by archetype, and maintains structured research under docs/reference-repos/.

Pinia Skill
Expert assistance for implementing Pinia state management in Vue 3 applications.
Capabilities
- Create type-safe Pinia stores
- Implement actions for async operations
- Define getters for computed state
- Configure Pinia plugins (persistence, etc.)
- Set up store composition patterns
- Integrate with Vue DevTools
Usage
Invoke this skill when you need to:
- Set up global state management in Vue
- Create feature-specific stores
- Implement persistent state
- Compose multiple stores
- Handle async state operations
Inputs
| Parameter | Type | Required | Description |
|---|
| storeName | string | Yes | Store name (use prefix) |
|
| actions | array | Yes | Store actions |
| getters | array | No | Computed getters |
| persist | boolean | No | Enable persistence |
Configuration Example
{
"storeName": "useUserStore",
"stateShape": {
"user": null,
"isAuthenticated": false
},
"actions": ["login", "logout", "fetchUser"],
"getters": ["fullName", "isAdmin"],
"persist": true
}
Store Patterns
Setup Store (Recommended)
import { ref, computed } from 'vue';
import { defineStore } from 'pinia';
interface User {
id: string;
name: string;
email: string;
role: 'user' | 'admin';
}
export const useUserStore = defineStore('user', () => {
const user = ref<User | null>(null);
const loading = ref(false);
const error = ref<string | null>(null);
const isAuthenticated = computed(() => !!user.value);
const isAdmin = computed(() => user.value?.role === 'admin');
const fullName = computed(() => user.value?.name ?? 'Guest');
async function login(email: string, password: string) {
loading.value = true;
error.value = null;
try {
const response = await fetch('/api/auth/login', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ email, password }),
});
if (!response.ok) {
throw new Error('Invalid credentials');
}
const data = await response.json();
user.value = data.user;
localStorage.setItem('token', data.token);
} catch (e) {
error.value = (e as Error).message;
throw e;
} finally {
loading.value = false;
}
}
async function logout() {
user.value = null;
localStorage.removeItem('token');
}
async function fetchUser() {
const token = localStorage.getItem('token');
if (!token) return;
loading.value = true;
try {
const response = await fetch('/api/auth/me', {
headers: { Authorization: `Bearer ${token}` },
});
user.value = await response.json();
} catch (e) {
logout();
} finally {
loading.value = false;
}
}
return {
user,
loading,
error,
isAuthenticated,
isAdmin,
fullName,
login,
logout,
fetchUser,
};
});
Options Store
import { defineStore } from 'pinia';
interface CartItem {
id: string;
name: string;
price: number;
quantity: number;
}
export const useCartStore = defineStore('cart', {
state: () => ({
items: [] as CartItem[],
}),
getters: {
totalItems: (state) =>
state.items.reduce((sum, item) => sum + item.quantity, 0),
totalPrice: (state) =>
state.items.reduce((sum, item) => sum + item.price * item.quantity, 0),
isEmpty: (state) => state.items.length === 0,
},
actions: {
addItem(item: Omit<CartItem, 'quantity'>) {
const existing = this.items.find((i) => i.id === item.id);
if (existing) {
existing.quantity++;
} else {
this.items.push({ ...item, quantity: 1 });
}
},
removeItem(id: string) {
const index = this.items.findIndex((i) => i.id === id);
if (index > -1) {
this.items.splice(index, 1);
}
},
updateQuantity(id: string, quantity: number) {
const item = this.items.find((i) => i.id === id);
if (item) {
item.quantity = Math.max(0, quantity);
if (item.quantity === 0) {
this.removeItem(id);
}
}
},
clearCart() {
this.items = [];
},
},
});
Pinia Setup with Plugins
import { createApp } from 'vue';
import { createPinia } from 'pinia';
import piniaPluginPersistedstate from 'pinia-plugin-persistedstate';
import App from './App.vue';
const pinia = createPinia();
pinia.use(piniaPluginPersistedstate);
const app = createApp(App);
app.use(pinia);
app.mount('#app');
export const useSettingsStore = defineStore('settings', {
state: () => ({
theme: 'light',
language: 'en',
}),
persist: true,
});
export const useUserStore = defineStore('user', {
state: () => ({
user: null,
token: null,
}),
persist: {
key: 'user-store',
storage: sessionStorage,
paths: ['token'],
},
});
Store Composition
import { defineStore } from 'pinia';
import { useCartStore } from './cart';
import { useUserStore } from './user';
export const useCheckoutStore = defineStore('checkout', () => {
const cart = useCartStore();
const user = useUserStore();
const canCheckout = computed(() => {
return user.isAuthenticated && !cart.isEmpty;
});
async function processCheckout(paymentMethod: string) {
if (!canCheckout.value) {
throw new Error('Cannot checkout');
}
const order = {
userId: user.user!.id,
items: cart.items,
total: cart.totalPrice,
paymentMethod,
};
const response = await fetch('/api/orders', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(order),
});
if (response.ok) {
cart.clearCart();
}
return response.json();
}
return {
canCheckout,
processCheckout,
};
});
Usage in Components
<script setup lang="ts">
import { storeToRefs } from 'pinia';
import { useUserStore } from '@/stores/user';
const userStore = useUserStore();
// Destructure with reactivity preserved
const { user, isAuthenticated, loading } = storeToRefs(userStore);
// Actions can be destructured directly
const { login, logout } = userStore;
async function handleLogin() {
try {
await login(email.value, password.value);
router.push('/dashboard');
} catch (e) {
// Handle error
}
}
</script>
<template>
<div v-if="loading">Loading...</div>
<div v-else-if="isAuthenticated">
Welcome, {{ user?.name }}
<button @click="logout">Logout</button>
</div>
<LoginForm v-else @submit="handleLogin" />
</template>
Best Practices
- Prefer setup stores for better TypeScript support
- Use storeToRefs for reactive destructuring
- Compose stores for complex features
- Keep stores focused on single concerns
- Use plugins for cross-cutting concerns
