What it does

Coding Standards is an agent skill from affaan-m/ECC. TypeScript, JavaScript, React ve Node.js geliştirme için evrensel kodlama standartları, en iyi uygulamalar ve kalıplar.

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code quality. It works with React, JavaScript, TypeScript and Node.js. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

When your agent uses it

  • Tasks that involve Code quality

Example prompts

  • “/coding-standards”

Requirements

  • Node.js

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Önce Okunabilirlik
  2. KISS (Keep It Simple, Stupid - Basit Tut)
  3. DRY (Don't Repeat Yourself - Kendini Tekrar Etme)
  4. YAGNI (You Aren't Gonna Need It - İhtiyacın Olmayacak)
  5. Uzun Fonksiyonlar
  6. Derin İç İçe Geçme
  7. Sihirli Sayılar

What it can do on your machine

Read from SKILL.md and the folder at commit ef648e0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Coding Standards loads about 3k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 259 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Kodlama Standartları ve En İyi Uygulamalar

Tüm projelerde uygulanabilir evrensel kodlama standartları.

Ne Zaman Aktifleştirmelisiniz

  • Yeni bir proje veya modül başlatırken
  • Kod kalitesi ve sürdürülebilirlik için kod incelerken
  • Mevcut kodu kurallara uygun hale getirmek için refactor ederken
  • İsimlendirme, biçimlendirme veya yapısal tutarlılığı zorunlu kılarken
  • Linting, biçimlendirme veya tür kontrolü kuralları ayarlarken
  • Yeni katkıda bulunanları kodlama kurallarına alıştırırken

Kod Kalitesi İlkeleri

1. Önce Okunabilirlik
  • Kod yazılmaktan çok okunur
  • Net değişken ve fonksiyon isimleri
  • Yorumlardan çok kendi kendini belgeleyen kod tercih edilir
  • Tutarlı biçimlendirme
2. KISS (Keep It Simple, Stupid - Basit Tut)
  • Çalışan en basit çözüm
  • Aşırı mühendislikten kaçının
  • Erken optimizasyon yapmayın
  • Anlaşılır kod > akıllıca kod
3. DRY (Don't Repeat Yourself - Kendini Tekrar Etme)
  • Ortak mantığı fonksiyonlara çıkarın
  • Yeniden kullanılabilir bileşenler oluşturun
  • Yardımcı araçları modüller arasında paylaşın
  • Kopyala-yapıştır programlamadan kaçının
4. YAGNI (You Aren't Gonna Need It - İhtiyacın Olmayacak)
  • İhtiyaç duyulmadan özellikler oluşturmayın
  • Spekülatif genellemeden kaçının
  • Karmaşıklığı sadece gerektiğinde ekleyin
  • Basit başlayın, gerektiğinde refactor edin

Yorumlar ve Dokümantasyon

Ne Zaman Yorum Yapmalı
typescript
// PASS: İYİ: NİÇİN'i açıklayın, NE'yi değil
// Kesintiler sırasında API'yi aşırı yüklemekten kaçınmak için exponential backoff kullan
const delay = Math.min(1000 * Math.pow(2, retryCount), 30000)

// Büyük dizilerle performans için burada kasıtlı olarak mutasyon kullanılıyor
items.push(newItem)

// FAIL: KÖTÜ: Açık olanı belirtmek
// Sayacı 1 artır
count++

// İsmi kullanıcının ismine ayarla
name = user.name
Public API'ler için JSDoc
typescript
/**
 * Semantik benzerlik kullanarak market arar.
 *
 * @param query - Doğal dil arama sorgusu
 * @param limit - Maksimum sonuç sayısı (varsayılan: 10)
 * @returns Benzerlik skoruna göre sıralanmış market dizisi
 * @throws {Error} OpenAI API başarısız olursa veya Redis kullanılamazsa
 *
 * @example
 * ```typescript
 * const results = await searchMarkets('election', 5)
 * console.log(results[0].name) // "Trump vs Biden"
 * ```
 */
export async function searchMarkets(
  query: string,
  limit: number = 10
): Promise<Market[]> {
  // Implementation
}

Performans En İyi Uygulamaları

Memoization
typescript
import { useMemo, useCallback } from 'react'

// PASS: İYİ: Pahalı hesaplamaları memoize et
const sortedMarkets = useMemo(() => {
  return markets.sort((a, b) => b.volume - a.volume)
}, [markets])

// PASS: İYİ: Callback'leri memoize et
const handleSearch = useCallback((query: string) => {
  setSearchQuery(query)
}, [])
Lazy Loading
typescript
import { lazy, Suspense } from 'react'

// PASS: İYİ: Ağır bileşenleri lazy yükle
const HeavyChart = lazy(() => import('./HeavyChart'))

export function Dashboard() {
  return (
    <Suspense fallback={<Spinner />}>
      <HeavyChart />
    </Suspense>
  )
}
Veritabanı Sorguları
typescript
// PASS: İYİ: Sadece gerekli sütunları seç
const { data } = await supabase
  .from('markets')
  .select('id, name, status')
  .limit(10)

// FAIL: KÖTÜ: Her şeyi seç
const { data } = await supabase
  .from('markets')
  .select('*')

Test Standartları

Test Yapısı (AAA Kalıbı)
typescript
test('benzerliği doğru hesaplar', () => {
  // Arrange (Hazırla)
  const vector1 = [1, 0, 0]
  const vector2 = [0, 1, 0]

  // Act (İşle)
  const similarity = calculateCosineSimilarity(vector1, vector2)

  // Assert (Doğrula)
  expect(similarity).toBe(0)
})
Test İsimlendirme
typescript
// PASS: İYİ: Açıklayıcı test isimleri
test('sorguya uygun market bulunamadığında boş dizi döndürür', () => { })
test('OpenAI API anahtarı eksikse hata fırlatır', () => { })
test('Redis kullanılamazsa substring aramaya geri döner', () => { })

// FAIL: KÖTÜ: Belirsiz test isimleri
test('çalışır', () => { })
test('arama testi', () => { })

Kod Kokusu Tespiti

Bu anti-kalıplara dikkat edin:

1. Uzun Fonksiyonlar
typescript
// FAIL: KÖTÜ: 50 satırdan uzun fonksiyon
function processMarketData() {
  // 100 satır kod
}

// PASS: İYİ: Küçük fonksiyonlara böl
function processMarketData() {
  const validated = validateData()
  const transformed = transformData(validated)
  return saveData(transformed)
}
2. Derin İç İçe Geçme
typescript
// FAIL: KÖTÜ: 5+ seviye iç içe geçme
if (user) {
  if (user.isAdmin) {
    if (market) {
      if (market.isActive) {
        if (hasPermission) {
          // Bir şeyler yap
        }
      }
    }
  }
}

// PASS: İYİ: Erken dönüşler
if (!user) return
if (!user.isAdmin) return
if (!market) return
if (!market.isActive) return
if (!hasPermission) return

// Bir şeyler yap
3. Sihirli Sayılar
typescript
// FAIL: KÖTÜ: Açıklanmamış sayılar
if (retryCount > 3) { }
setTimeout(callback, 500)

// PASS: İYİ: İsimlendirilmiş sabitler
const MAX_RETRIES = 3
const DEBOUNCE_DELAY_MS = 500

if (retryCount > MAX_RETRIES) { }
setTimeout(callback, DEBOUNCE_DELAY_MS)

Unutmayın: Kod kalitesi pazarlık konusu değildir. Açık, sürdürülebilir kod hızlı geliştirme ve güvenli refactoring sağlar.
