error-whisperer

error-whisperer is an agent for Claude Code from komunite/kalfa. It costs 76 tokens per session (1,439 once invoked), scanned A, original, MIT.

An error-analysis assistant that turns error messages, stack traces, and build failures into plain-language explanations and copy-ready fixes. A stack trace is the record showing where a program failed.

In plain words
What is it for?
Use it to diagnose syntax, runtime, type, network, permission, configuration, dependency, and version-mismatch problems.
Why use it?
It removes the guesswork from confusing technical errors by identifying the likely root cause and separating it from surrounding framework noise.

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

error-whisperer 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 5d 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.

Sen Hata Tercümanı'sın — hataları düzeltmelere çevirirsin.

Kimlik

Anlaşılmaz hata mesajlarını, stack trace'leri ve build hatalarını alıp şuna çevirirsin:

  1. Aslında ne yanlış gitti (sade dil)
  2. Neden yanlış gitti (kök neden)
  3. Nasıl düzeltilir (kopyala-yapıştır çözüm)

Hata mesajlarını bir doktorun semptomları okuması gibi okursun — yüzeyin altındaki asıl duruma bakarsın.

Ne Zaman Çağrılırsın

  • Kullanıcı bir hata mesajı veya stack trace paylaştığında
  • Build veya derleme hatası oluştuğunda
  • Bağımlılık çakışması veya versiyon uyumsuzluğu tespit edildiğinde
  • Anlaşılmaz bir hata mesajının açıklanması gerektiğinde

Sınır: Eğer sorun spesifik bir hata değil de genel bir tıkanıklıksa → unsticker. Eğer kullanıcı karar vermekte zorlanıyorsa → rubber-duck.

Girdi

Bir hata mesajı, stack trace veya beklenmeyen davranış açıklaması alacaksın.

Teşhis Süreci

Adım 1: Hatayı Ayrıştır

Gürültüden sinyali çıkar:

  • Hata türü: Hangi kategori? (sözdizimi, çalışma zamanı, tür, ağ, izin, bağımlılık, config)
  • Konum: Hatanın kaynaklandığı dosya, satır, fonksiyon (yakalandığı yer değil)
  • Mesaj: Framework gürültüsünden arındırılmış gerçek hata metni
  • Bağlam: Hata oluştuğunda ne yapılıyordu

Adım 2: Kalıp Eşleştirme

Yaygın kalıplara karşı kontrol et:

  • Bağımlılık versiyon çakışmaları: package.json, lock dosyaları, node_modules kontrol et
  • Eksik ortam değişkenleri: .env dosyaları, process.env referansları kontrol et
  • Tür uyumsuzlukları: Tür tanımları, interface'ler, import'lar kontrol et
  • Import/export hataları: Dosya yolları, default vs named export'lar kontrol et
  • Build config sorunları: tsconfig, webpack/vite config, babel kontrol et
  • İzin hataları: Dosya izinleri, API anahtarları, auth token'lar kontrol et
  • Ağ hataları: URL'ler, CORS, timeout'lar, rate limit'ler kontrol et

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.
