maestro: Skill for Claude Code

.claude/skills/example-frontend-patterns/SKILL.md

example-frontend-patterns is a skill for Claude Code from CarlosDanielDev/maestro. It costs 34 tokens per session (1,185 once invoked), scanned A, original, MIT.

A template of frontend web development guidance. Frontend code runs in the user's browser and controls the visible interface, and the template includes examples for React, Vue, Angular, and Svelte.

In plain words
What is it for?
Use it to document component patterns and other web-interface practices for frontend development agents. It is a reference template, not a complete application or a direct user command.
Why use it?
It provides a shared starting point for interface conventions and examples. It must be customised for the project's actual frontend framework before it can serve as project guidance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

example-frontend-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How to Customize Replace examples below with your framework's patterns

Step 1: Choose Your Framework

Replace this section with your framework-specific requirements:

Option A: React

// Example: React with hooks and TypeScript
import React, { useState, useEffect } from 'react'

interface Props {
  data: DataType
}

export const MyComponent: React.FC<Props> = ({ data }) => {
  const [state, setState] = useState<StateType>(initialState)

  useEffect(() => {
    // side effects
  }, [dependencies])

  return <div>{/* JSX */}</div>
}

Option B: Vue 3

<template>
  <div>{{ data }}</div>
</template>

<script setup lang="ts">
import { ref, computed, onMounted } from 'vue'

const data = ref<DataType>(initialValue)
const computedValue = computed(() => data.value * 2)

onMounted(() => {
  // lifecycle hook
})
</script>

Option C: Angular

// Example: Angular component with TypeScript
import { Component, OnInit } from '@angular/core'

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit {
  data: DataType

  constructor(private service: MyService) {}

  ngOnInit(): void {
    // initialization
  }
}

Option D: Svelte

<script lang="ts">
  import { onMount } from 'svelte'

  let data: DataType = initialValue

  $: computedValue = data * 2

  onMount(() => {
    // lifecycle
  })
</script>

<div>{data}</div>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
